Add a new default_streamid configuration option for the SRT server to
allow customization of the default streamid used when SRT clients
connect without setting the SRTO_STREAMID socket option.
When SRT clients (like VLC) connect without properly setting the
SRTO_STREAMID socket option, SRS previously used a hardcoded default
value of "#!::r=live/livestream,m=publish". This caused conflicts when:
1. A publisher connects without setting streamid (uses default publish
mode)
2. A player tries to connect without setting streamid (also uses default
publish mode)
3. The player gets a "Stream already exists or busy" error because both
are trying to publish
Start SRS with default stream id as viewer:
```bash
./objs/srs -c conf/srt.vlc.conf
```
Publish SRT stream by FFmpeg:
```bash
ffmpeg -re -i ./doc/source.flv -c copy -pes_payload_size 0 -f mpegts \
'srt://127.0.0.1:10080?streamid=#!::r=live/livestream,m=publish'
```
Play SRT stream by ffplay:
```bash
ffplay 'srt://127.0.0.1:10080?streamid=#!::r=live/livestream,m=request'
```
Play SRT stream by VLC:
```
✅ Correct - Use simple URL without streamid parameter:
srt://127.0.0.1:10080
❌ Wrong - VLC doesn't support streamid parameter:
srt://127.0.0.1:10080?streamid=#!::r=live/livestream,m=request
```

The issue occurred when srs_rtp_seq_distance(start, end) + 1 resulted in
values <= 0
due to sequence number wraparound (e.g., when end < start). This caused
assertion
failures and server crashes.
SrsRtcFrameBuilder::check_frame_complete(): Added validation to return
false
for invalid sequence ranges instead of asserting.
However, it maybe cause converting RTC to RTMP stream failure, because
this issue
should be caused by the problem of sequence number of RTP, which means
there potentially
be stream problem in RTC stream. Even so, changing assert to warning
logs is better,
because SRS should not crash when stream is corrupt.

Try to fix#4450
## Cause
The SRS transcode rtp packets, whose sequence number in range [start,
end], to one rtmp packet, but when the first rtp packet is empty, then
this crash happens.
check #4450 for details.
## Impact
5.0release and 6.0release branch.
develop branch already has its own solution.
So this PR is targeting to **6.0release**.
## Solution
find the first not empty rtp packet in seq range [start, end].

HLS and DASH components had redundant `enabled` flag checks in their
`cycle()` and `cleanup_delay()` methods that prevented proper cleanup of
files when components were disabled. This created a race condition
where:
1. Stream stops publishing and HLS/DASH components get disabled
2. `cycle()` returns early without performing disposal operations
3. `cleanup_delay()` returns 0 instead of configured disposal timeout
4. Source cleanup doesn't wait long enough for file disposal
5. HLS/DASH files remain on disk without proper cleanup
The `enabled` flag should control processing of **new incoming
streams**, but should NOT prevent **cleanup of existing files** from
previously enabled streams.
Remove redundant `enabled` checks from:
- `SrsHls::cycle()` and `SrsDash::cycle()` - Allow disposal logic to run
even when disabled
- `SrsHls::cleanup_delay()` and `SrsDash::cleanup_delay()` - Always
return proper disposal timeout

Fixes#3993 - WebRTC streams recorded to MP4 via DVR exhibit audio/video
synchronization issues, with audio typically ahead of video. **Note:
This issue is specific to MP4 format; FLV recordings are not affected.**
When WebRTC streams are converted to RTMP and then muxed to MP4, the
audio and video tracks may start at different timestamps. The MP4 muxer
was not accounting for this timing offset between the first audio and
video samples in the STTS (Sample Time-to-Sample) table, causing the
tracks to be misaligned in the final MP4 file.
Introduces `SrsMp4DvrJitter` class specifically for MP4 audio/video
synchronization:
- **Timestamp Tracking**: Records the DTS of the first audio and video
samples
- **Offset Calculation**: Computes the timing difference between track
start times
- **MP4 STTS Correction**: Sets appropriate `sample_delta` values in the
MP4 STTS table to maintain proper A/V sync
- Added `SrsMp4DvrJitter` class in `srs_kernel_mp4.hpp/cpp`
- Integrated jitter correction into `SrsMp4SampleManager::write_track()`
for MP4 format only
- Added comprehensive unit tests covering various timing scenarios
- **Scope**: Changes are isolated to MP4 kernel code and do not affect
FLV processing
This fix ensures that MP4 DVR recordings from WebRTC streams maintain
proper audio/video synchronization regardless of the relative timing of
the first audio and video frames, while leaving FLV format processing
unchanged.

Fixes a critical heap-use-after-free crash in HTTP-FLV streaming that
occurs when a client requests a stream while it's being unmounted
asynchronously.
- **Issue**: #4429 - Heap-use-after-free crash in
`SrsLiveStream::serve_http()`
- **Root Cause**: Race condition between coroutines in single-threaded
SRS server:
1. **Coroutine A**: HTTP client requests FLV stream → `serve_http()`
starts
2. **Coroutine B**: RTMP publisher disconnects → triggers async stream
destruction
3. **Async Worker**: Destroys `SrsLiveStream` object while Coroutine A
is yielded
4. **Coroutine A**: Resumes and accesses freed memory → **CRASH**
1. **Early viewer registration**: Add HTTP connection to `viewers_` list
immediately in `serve_http()` before any I/O operations that could yield
2. **Lifecycle protection**: Split `serve_http()` into wrapper and
implementation to ensure proper viewer management
3. **Stream availability checks**: Add fast checks for stream disposal
state before critical operations
4. **Improved error handling**: Convert warnings to fatal errors when
trying to free alive streams
- **`SrsLiveStream::serve_http()`**: Now immediately registers viewer
and delegates to `serve_http_impl()`
- **`SrsLiveStream::serve_http_impl()`**: Contains the actual HTTP
serving logic
- **`SrsHttpStreamDestroy::call()`**: Enhanced error handling and longer
wait timeout
- **Stream state validation**: Added checks for `entry->enabled` before
proceeding with stream operations
Fixes#4429
For H.264, only when the NAL Type is 1, 2, 3, or 4 is it possible for
B-frames to be present; that is, non-IDR pictures and slice data.
The current `SrsVideoFrame::parse_avc_bframe()` function uses incorrect
logic to determine if a NALU can contain B-frames. The original
implementation only checked for specific NALU types (IDR, SPS, PPS) to
mark as non-B-frames, but this approach misses many other NALU types
that cannot contain B-frames according to the H.264 specification.
According to H.264 specification (ISO_IEC_14496-10-AVC-2012.pdf, Table
7-1), B-frames can **only** exist in these specific NALU types:
- Type 1: Non-IDR coded slice (`SrsAvcNaluTypeNonIDR`)
- Type 2: Coded slice data partition A (`SrsAvcNaluTypeDataPartitionA`)
- Type 3: Coded slice data partition B (`SrsAvcNaluTypeDataPartitionB`)
- Type 4: Coded slice data partition C (`SrsAvcNaluTypeDataPartitionC`)
All other NALU types (IDR=5, SEI=6, SPS=7, PPS=8, AUD=9, etc.) cannot
contain B-frames by definition.

1. When the chunk message header employs type 1 and type 2, the extended
timestamp denotes the time delta.
2. When the DTS (Decoding Time Stamp) experiences a jump and exceeds
16777215, there can be errors in DTS calculation, and if the audio and
video delta differs, it may result in audio-video synchronization
issues.

The heartbeat of SRS is a timer that requests an HTTP URL. We can use
this heartbeat to report the necessary information for registering the
backend server with the proxy server.
```text
SRS(backend) --heartbeat---> Proxy server
```
A proxy server is a specialized load balancer for media servers. It
operates at the application level rather than the TCP level. For more
information about the proxy server, see issue #4158.
Note that we will merge this PR into SRS 5.0+, allowing the use of SRS
5.0+ as the backend server, not limited to SRS 7.0. However, the proxy
server is introduced in SRS 7.0.
It's also possible to implement a registration service, allowing you to
use other media servers as backend servers. For example, if you gather
information about an nginx-rtmp server and register it with the proxy
server, the proxy will forward RTMP streams to nginx-rtmp. The backend
server is not limited to SRS.

1. Do not create a source when mounting FLV because it may not unmount
FLV when freeing the source. If you access the FLV stream without any
publisher, then wait for source cleanup and review the FLV stream again,
there is an annoying warning message.
```bash
HTTP #0 127.0.0.1:58026 GET http://localhost:8080/live/livestream.flv, content-length=-1
new live source, stream_url=/live/livestream
http: mount flv stream for sid=/live/livestream, mount=/live/livestream.flv
client disconnect peer. ret=1007
Live: cleanup die source, id=[], total=1
HTTP #0 127.0.0.1:58040 GET http://localhost:8080/live/livestream.flv, content-length=-1
serve error code=1097(NoSource)(No source found) : process request=0 : cors serve : serve http : no source for /live/livestream
serve_http() [srs_app_http_stream.cpp:641]
```
> Note: There is an inconsistency. The first time, you can access the
FLV stream and wait for the publisher, but the next time, you cannot.
2. Create a source when starting to serve the FLV client. We do not need
to create the source when creating the HTTP handler. Instead, we should
try to create the source in the cache or stream. Because the source
cleanup does not unmount the HTTP handler, the handler remains after the
source is destroyed. The next time you access the FLV stream, the source
is not found.
```cpp
srs_error_t SrsHttpStreamServer::hijack(ISrsHttpMessage* request, ISrsHttpHandler** ph) {
SrsSharedPtr<SrsLiveSource> live_source;
if ((err = _srs_sources->fetch_or_create(r.get(), server, live_source)) != srs_success) { }
if ((err = http_mount(r.get())) != srs_success) { }
srs_error_t SrsBufferCache::cycle() {
SrsSharedPtr<SrsLiveSource> live_source = _srs_sources->fetch(req);
if (!live_source.get()) {
return srs_error_new(ERROR_NO_SOURCE, "no source for %s", req->get_stream_url().c_str());
}
srs_error_t SrsLiveStream::serve_http(ISrsHttpResponseWriter* w, ISrsHttpMessage* r) {
SrsSharedPtr<SrsLiveSource> live_source = _srs_sources->fetch(req);
if (!live_source.get()) {
return srs_error_new(ERROR_NO_SOURCE, "no source for %s", req->get_stream_url().c_str());
}
```
> Note: We should not create the source in hijack, instead, we create it
in cache or stream:
```cpp
srs_error_t SrsHttpStreamServer::hijack(ISrsHttpMessage* request, ISrsHttpHandler** ph) {
if ((err = http_mount(r.get())) != srs_success) { }
srs_error_t SrsBufferCache::cycle() {
SrsSharedPtr<SrsLiveSource> live_source;
if ((err = _srs_sources->fetch_or_create(req, server_, live_source)) != srs_success) { }
srs_error_t SrsLiveStream::serve_http(ISrsHttpResponseWriter* w, ISrsHttpMessage* r) {
SrsSharedPtr<SrsLiveSource> live_source;
if ((err = _srs_sources->fetch_or_create(req, server_, live_source)) != srs_success) { }
```
> Note: This fixes the failure and annoying warning message, and
maintains consistency by always waiting for the stream to be ready if
there is no publisher.
3. Fail the http request if the HTTP handler is disposing, and also keep
the handler entry when disposing the stream, because we should dispose
the handler entry and stream at the same time.
```cpp
srs_error_t SrsHttpStreamServer::http_mount(SrsRequest* r) {
entry = streamHandlers[sid];
if (entry->disposing) {
return srs_error_new(ERROR_STREAM_DISPOSING, "stream is disposing");
}
void SrsHttpStreamServer::http_unmount(SrsRequest* r) {
std::map<std::string, SrsLiveEntry*>::iterator it = streamHandlers.find(sid);
SrsUniquePtr<SrsLiveEntry> entry(it->second);
entry->disposing = true;
```
> Note: If the disposal process takes a long time, this will prevent
unexpected behavior or access to the resource that is being disposed of.
4. In edge mode, the edge ingester will unpublish the source when the
last consumer quits, which is actually triggered by the HTTP stream.
While it also waits for the stream to quit when the HTTP unmounts, there
is a self-destruction risk: the HTTP live stream object destroys itself.
```cpp
srs_error_t SrsLiveStream::serve_http(ISrsHttpResponseWriter* w, ISrsHttpMessage* r) {
SrsUniquePtr<SrsLiveConsumer> consumer(consumer_raw); // Trigger destroy.
void SrsHttpStreamServer::http_unmount(SrsRequest* r) {
for (;;) { if (!cache->alive() && !stream->alive()) { break; } // A circle reference.
mux.unhandle(entry->mount, stream.get()); // Free the SrsLiveStream itself.
```
> Note: It also introduces a circular reference in the object
relationships, the stream reference to itself when unmount:
```text
SrsLiveStream::serve_http
-> SrsLiveConsumer::~SrsLiveConsumer -> SrsEdgeIngester::stop
-> SrsLiveSource::on_unpublish -> SrsHttpStreamServer::http_unmount
-> SrsLiveStream::alive
```
> Note: We should use an asynchronous worker to perform the cleanup to
avoid the stream destroying itself and to prevent self-referencing.
```cpp
void SrsHttpStreamServer::http_unmount(SrsRequest* r) {
entry->disposing = true;
if ((err = async_->execute(new SrsHttpStreamDestroy(&mux, &streamHandlers, sid))) != srs_success) { }
```
> Note: This also ensures there are no circular references and no
self-destruction.

Edge FLV is not working because it is stuck in an infinite loop waiting.
Previously, there was no need to wait for exit since resources were not
being cleaned up. Now, since resources need to be cleaned up, it must
wait for all active connections to exit, which causes this issue.
To reproduce the issue, start SRS edge, run the bellow command and press
`CTRL+C` to stop the request:
```bash
curl http://localhost:8080/live/livestream.flv -v >/dev/null
```
It will cause edge to fetch stream from origin, and free the consumer
when client quit. When `SrsLiveStream::do_serve_http` return, it will
free the consumer:
```cpp
srs_error_t SrsLiveStream::do_serve_http(ISrsHttpResponseWriter* w, ISrsHttpMessage* r) {
SrsUniquePtr<SrsLiveConsumer> consumer(consumer_raw);
```
Keep in mind that in this moment, the stream is alive, because only set
to not alive after this function return:
```cpp
alive_viewers_++;
err = do_serve_http(w, r); // Free 'this' alive stream.
alive_viewers_--; // Crash here, because 'this' is freed.
```
When freeing the consumer, it will cause the source to unpublish and
attempt to free the HTTP handler, which ultimately waits for the stream
not to be alive:
```cpp
SrsLiveConsumer::~SrsLiveConsumer() {
source_->on_consumer_destroy(this);
void SrsLiveSource::on_consumer_destroy(SrsLiveConsumer* consumer) {
if (consumers.empty()) {
play_edge->on_all_client_stop();
void SrsLiveSource::on_unpublish() {
handler->on_unpublish(req);
void SrsHttpStreamServer::http_unmount(SrsRequest* r) {
if (stream->entry) stream->entry->enabled = false;
for (; i < 1024; i++) {
if (!cache->alive() && !stream->alive()) {
break;
}
srs_usleep(100 * SRS_UTIME_MILLISECONDS);
}
```
After 120 seconds, it will free the stream and cause SRS to crash
because the stream is still active. In order to track this potential
issue, also add an important warning log:
```cpp
srs_warn("http: try to free a alive stream, cache=%d, stream=%d", cache->alive(), stream->alive());
```
SRS may crash if got this log.

If SRS responds with this empty data packet, FFmpeg will receive an
empty stream, like `Stream #0:0: Data: none` in following logs:
```bash
ffmpeg -i rtmp://localhost:11935/live/livestream
```
This won't cause the player to fail, but it will inconvenience the user
significantly. It may also cause FFmpeg slower to analysis the stream,
see #3767

When stopping the stream, it will wait for the HTTP Streaming to exit.
If the HTTP Streaming goroutine hangs, it will not exit automatically.
```cpp
void SrsHttpStreamServer::http_unmount(SrsRequest* r)
{
SrsUniquePtr<SrsLiveStream> stream(entry->stream);
if (stream->entry) stream->entry->enabled = false;
srs_usleep(...); // Wait for about 120s.
mux.unhandle(entry->mount, stream.get()); // Free stream.
}
srs_error_t SrsLiveStream::serve_http(ISrsHttpResponseWriter* w, ISrsHttpMessage* r)
{
err = do_serve_http(w, r); // If stuck in here for 120s+
alive_viewers_--; // Crash at here, because stream has been deleted.
```
We should notify http stream connection to interrupt(expire):
```cpp
void SrsHttpStreamServer::http_unmount(SrsRequest* r)
{
SrsUniquePtr<SrsLiveStream> stream(entry->stream);
if (stream->entry) stream->entry->enabled = false;
stream->expire(); // Notify http stream to interrupt.
```
Note that we should notify all viewers pulling stream from this http
stream.
Note that we have tried to fix this issue, but only try to wait for all
viewers to quit, without interrupting the viewers, see
https://github.com/ossrs/srs/pull/4144

2. Always call _srs_thread_pool->initialize for single thread.
3. Support `--signal-api` to send signal by HTTP API, because CLion
eliminate the signals.

New features for valgrind:
1. ST: Support /api/v1/valgrind for leaking check.
2. ST: Support /api/v1/valgrind?check=full|added|changed|new|quick
To use Valgrind to detect memory leaks in SRS, even though Valgrind
hooks are supported in ST, there are still many false positives. A more
reasonable approach is to have Valgrind report incremental memory leaks.
This way, global and static variables can be avoided, and detection can
be achieved without exiting the program. Follow these steps:
1. Compile SRS with Valgrind support: `./configure --valgrind=on &&
make`
2. Start SRS with memory leak detection enabled: `valgrind
--leak-check=full ./objs/srs -c conf/console.conf`
3. Trigger memory detection by using curl to access the API and generate
calibration data. There will still be many false positives, but these
can be ignored: `curl http://127.0.0.1:1985/api/v1/valgrind?check=added`
4. Perform load testing or test the suspected leaking functionality,
such as RTMP streaming: `ffmpeg -re -i doc/source.flv -c copy -f flv
rtmp://127.0.0.1/live/livestream`
5. Stop streaming and wait for SRS to clean up the Source memory,
approximately 30 seconds.
6. Perform incremental memory leak detection. The reported leaks will be
very accurate at this point: `curl
http://127.0.0.1:1985/api/v1/valgrind?check=added`
> Note: To avoid interference from the HTTP request itself on Valgrind,
SRS uses a separate coroutine to perform periodic checks. Therefore,
after accessing the API, you may need to wait a few seconds for the
detection to be triggered.

I did some preliminary code inspection. The two playback endpoints share
the same `SrsLiveStream` instance. After the first one disconnects,
`alive_` is set to false.
```
alive_ = true;
err = do_serve_http(w, r);
alive_ = false;
```
In the `SrsHttpStreamServer::http_unmount(SrsRequest* r)` function,
`stream->alive()` is already false, so `mux.unhandle` will free the
`SrsLiveStream`. This causes the other connection coroutine to return to
its execution environment after the `SrsLiveStream` instance has already
been freed.
```
// Wait for cache and stream to stop.
int i = 0;
for (; i < 1024; i++) {
if (!cache->alive() && !stream->alive()) {
break;
}
srs_usleep(100 * SRS_UTIME_MILLISECONDS);
}
// Unmount the HTTP handler, which will free the entry. Note that we must free it after cache and
// stream stopped for it uses it.
mux.unhandle(entry->mount, stream.get());
```
`alive_` was changed from a `bool` to an `int` to ensure that
`mux.unhandle` is only executed after each connection's `serve_http` has
exited.

When unpublishing, the handler callback that will stop the coroutine:
```cpp
_can_publish = true;
handler->on_unpublish(req);
```
In this handler, the `http_unmount` will be called:
```cpp
void SrsHttpStreamServer::http_unmount(SrsRequest* r)
cache->stop();
```
In this `http_unmount` function, there could be context switching. In
such a situation, a new connection might publish the stream while the
unpublish process is freeing the stream, leading to a crash.
To prevent a new publisher, we should change the state only after all
handlers and hooks are completed.

## Describe ##
http_remux feature support config `has_audio`, `has_video` &
`guess_has_av` prop.
282d94d7bb/trunk/src/app/srs_app_http_stream.cpp (L630-L632)
Take `http_flv` as example, `srs` can accept both RTMP streams with only
audio, only video or both audio and video streams. It is controlled by
above three properties.
But `guess_has_av` is not implemented by `http_ts`. The problem is that
if I want publish a RTMP stream with audio or video track, the
`has_audio` and `has_video`, which are default true/on, must to be
config to match the RTMP stream, otherwise the `mpegts.js` player can't
play the `http-ts` stream.
## How to reproduce ##
1. `export SRS_VHOST_HTTP_REMUX_HAS_AUDIO=on; export
SRS_VHOST_HTTP_REMUX_HAS_VIDEO=on; export
SRS_VHOST_HTTP_REMUX_GUESS_HAS_AV=on; ./objs/srs -c
conf/http.ts.live.conf`
2. publish rtmp stream without video: `ffmpeg -re -stream_loop -1 -i
srs/trunk/doc/source.200kbps.768x320.flv -vn -acodec copy -f flv
rtmp://localhost/live/livestream`
3. open chrome browser, open
`http://localhost:8080/players/srs_player.html?schema=http`, go to
`LivePlayer`, input URL: `http://localhost:8080/live/livestream.ts`,
click play.
4. the `http://localhost:8080/live/livestream.ts` can not play.
## Solution ##
Let `http-ts` support `guess_has_av`, `http-flv` already supported. The
`guess_has_av` default value is ture/on, so the `http-ts|flv` can play
any streams with audio, video or both.

1. Should always stop coroutine before close fd, see #511, #1784
2. When edge forwarder coroutine quit, always set the error code.
3. Do not unpublish if invalid state.

## Cause
dash auto dispose is configured by seconds, but the code compare by
usecond, 1 second = 1,000,000 useconds.
releated to #4097
Bug introduced after #4097 supported Dash auto dispose after a timeout
without media data.
## How to reproduce
1. `./objs/srs -c conf/dash.conf`
2. publish a rtmp stream.
3. play dash stream. -> no dash stream, always 404 error.

To manage an object:
```cpp
// Before
MyClass* ptr = new MyClass();
SrsAutoFree(MyClass, ptr);
ptr->do_something();
// Now
SrsUniquePtr<MyClass> ptr(new MyClass());
ptr->do_something();
```
To manage an array of objects:
```cpp
// Before
char* ptr = new char[10];
SrsAutoFreeA(char, ptr);
ptr[0] = 0xf;
// Now
SrsUniquePtr<char[]> ptr(new char[10]);
ptr[0] = 0xf;
```
In fact, SrsUniquePtr is a limited subset of SrsAutoFree, mainly
managing pointers and arrays. SrsUniquePtr is better than SrsAutoFree
because it has the same API to standard unique ptr.
```cpp
SrsUniquePtr<MyClass> ptr(new MyClass());
ptr->do_something();
MyClass* p = ptr.get();
```
SrsAutoFree actually uses a pointer to a pointer, so it can be set to
NULL, allowing the pointer's value to be changed later (this usage is
different from SrsUniquePtr).
```cpp
// OK to free ptr correctly.
MyClass* ptr;
SrsAutoFree(MyClass, ptr);
ptr = new MyClass();
// Crash because ptr is an invalid pointer.
MyClass* ptr;
SrsUniquePtr<MyClass> ptr(ptr);
ptr = new MyClass();
```
Additionally, SrsAutoFreeH can use specific release functions, which
SrsUniquePtr does not support.
