gstreamer recording m3u8 stream

Question

I'm trying to record stream from m3u8 file. This pipeline works:
gst-launch-0.10 -e souphttpsrc location=(mysrc.m3u8) ! queue ! hlsdemux ! queue ! mpegtsparse ! queue ! mpegtsdemux ! queue ! audio/mpeg ! queue ! filesink location=test.ts
and (sometimes) record audio stream.
But i can't record video, whatever i do it crashes.
I tried something like this:
gst-launch-0.10 souphttpsrc location=(mysrc.m3u8) ! queue ! hlsdemux ! queue ! mpegtsparse ! queue ! mpegtsdemux ! queue ! video/x-264 ! queue ! filesink location=test.ts
But it does nothing.

Answer 1

You are using gstreamer 0.10 which is obsolete and unmantained, all users should upgrade to the 1.x series.

Given that warning, it is not clear whether you want to save the mpegts stream or the streams inside it.

To save the mpegts stream you can just do:

gst-launch-1.0 http://path/to/your/stream.m3u8 ! hlsdemux ! filesink

Be aware that if the HLS playlist contains multiple bitrates hlsdemux might switch bitrate and it will fail as gst-launch-1.0 isn't capable of handling this. (it is a debugging and testing tool). You can likely set a fixed "connection-speed" to make it always use the same bitrate you desire to overcome this issue.

If you want to get only the video stream and you know it is H264, try:

gst-launch-1.0 http://path/to/your/stream.m3u8 ! hlsdemux ! tsdemux ! queue ! video/x-h264 ! filesink

It might be a better idea to save it to a container format to allow easier use later, with something like:

gst-launch-1.0 http://path/to/your/stream.m3u8 ! hlsdemux ! tsdemux ! queue ! video/x-h264 ! h264parse ! qtmux ! filesink

But, as I said, please move to 1.x, HLS is much better at 1.x than it was in 0.10 and it should work.
