Split MPEG-TS into MP4 files with gstreamer 1.12.2

Question

I have a MPEG-TS file which contains two video/audio stream-pairs:

$ gst-discoverer-1.0 Recorder_Aug01_12-30-39.ts
Analyzing Recorder_Aug01_12-30-39.ts
Done          


        

Answer 1

GStreamer Buffer has no PTS Failure Mode

This may not completely solve the problem using GStreamer, but this is a workaround that I'm now using. It involves isolating out the failing component which is the 'mp4mux' element in the gstreamer pipeline.

I'm finding that even a sample video encoding in Gstreamer is currently failing e.g. with the Buffer has no PTS failure mode:

gst-launch-1.0 videotestsrc num_buffers=300 ! videoconvert ! videoscale ! omxh264enc ! h264parse ! mp4mux ! filesink location=test.mp4

Using Gstreamer for h264 Encoding only.

Removing the mp4mux element allows us to successfully create .h264 files. Particularly handy if you're using a Raspberry Pi omxh264 encoder element.

gst-launch-1.0 videotestsrc num_buffers=300 ! videoconvert ! videoscale ! omxh264enc ! filesink location=test.h264

Solving the problem of Mixing Audio and Video

Now to convert that into an MP4 (the initial goal) we can use the nice lightweight Gpac MP4box.

sudo apt-get install gpac

MP4Box -isma -inter 250 -fps 30.0 -mpeg4 -hint -noprog -add test.h264 test.mp4

Then you can add in your audio

MP4Box -add audio.mp3 test.mp4

Summary

1. GStreamer appears currently broken with the No PTS failure mode when using Mp4Mux element.
2. GStreamer general h264 encoding and piplines are awesome, and working.
3. Using GPac to combine audio into Mp4 files is a viable alternative.
