[FFmpeg-devel] [GSoC] Qualification task (?) FFserver, further implementation

[Stephan Holljes]

This version contains some fixes including:
  - fix compiler warning
  - initial fixing of muxing non-matroska files
  - clarify documentation
unrelated but helpful for testing:
  - add address-sanitation to compilation

As mentioned, using non-matroska files does not properly work as of now.
Muxing to in-memory matroska yields:

> [matroska @ 0x61b00001ea80] Starting new cluster due to timestamp

Playback of the stream in mpv yields:

> Invalid audio PTS: 0.023220 -> 1.024000

Pointers for further investigation are appreciated! I'll next read more
doc/examples and possibly ffmpeg.c to understand more about timestamps.
