Watching a M3U8 stream that uses small TS files about obs-gstreamer

[crossan007]

Does the gstreamer test video src work for you?

That will at least tell us if obs-gstreamer is installed properly and "talking to" obs.

Also, what os are you on? What version of gstreamer, and what version of obs?

Running latest Windows 10 with latest gstreamer (32bit and 64bit) installed, the test works.

Not sure which pipeline and streams you have tried. But I have tested and added an HLS example to the README.md:

uridecodebin uri=http://184.72.239.149:1935/vod/mp4:sample.mp4/playlist.m3u8 name=bin ! queue ! video. bin. ! queue ! audio.

This did work just fine for me.

Doesn't seem to work with streams from VKontakte (VK).
Recently VK streams also stopped working on VLC Player, but is fixed on it's settings by changing MPEG-TS demuxer setting to not trust in-stream PCR and to seek based on percent not time.

VLC has following error without the fix:
ts demux error: libdvbpsi error (PSI decoder): TS duplicate (received 0, expected 1)

I assume these streams are not public accessible for testing?

So if they offer invalid streams do they do this on purpose? Anyway if they cannot be played with the gst-play-1.0 application there is nothing this plugin can do to fix this. Perhaps there are some specific GStreamer options on some of the elements in question like the workarounds in VLC - but I'm not sure. If the expectation is that GStreamer can play these streams I suggest to discuss these upstream to the GStreamer people as they are ones who may be able to fix it.

You can find VK streams here: https://vk.com/video
Opening a stream, right clicking it and copying the debug info gets you the Live HLS M3U8 file.

Yes, so it throws several errors. Its either multiple programs in these streams or broken in a way the parser completely freaks out. Most likely on purpose to get people using their site instead of grabbing streams by 3rd parties. IT's probably a cat and mouse game to keep up with whatever they are doing to their streams. Either way - if it supposed to get fixed it must be done by the GStreamer project. Nothing this plugin can do here, so I'm closing this.
