[FFmpeg-devel] [PATCH 00/20] Matroska muxer patches

[Andreas Rheinhardt]

Andreas Rheinhardt:
> This patchset is sort-of a revival of the part of a patchset I sent
> earlier [1], but which couldn't be applied fully because the way the
> webm_chunk muxer bypassed the API [2]. Now that this has been fixed [3],
> I have taken the opportunity to resend this patchset in an updated form.
> 
> It does not yet completely eliminate the limit on the number of tracks
> as requested in [4], but no longer counting attachments among the number
> of tracks is beneficial even if said limit will be removed.
