Re: [FFmpeg-devel] [PATCH v3 2/2] libavformat/oggparseopus: Clear existing stream metadata before parsing potentially new one. Fixes: #10363

[Romain Beauxis <toots@rastageeks.org>]

Hello again!

I wanted to see if there was any interest in this patch and the other one
adding metadata decoding for chained ogg bitstream. These two feel like
easy bugfixes and features to add to the next release.

Reproduction steps for this one are detailed here:
https://trac.ffmpeg.org/ticket/10363
