Correct, I missed it. It's just that I'm not getting any emails from this mailing list
(verified they are not getting to the junk folder...).
So I've been polling the page of the last message of this thread in ffmpeg.org,
and guess these posts were added to a different leaf of the message tree...
Would really appreciate it if this could be resolved, either add my work email -
eran dot kornblau at kaltura dot com or my personal email -
erankor at gmail dot com.

I see options to address this:
1. overwrite the codec_id only when it's AV_CODEC_ID_NONE
2. (stricter) save the format 4cc (that is loaded in ff_mov_read_stsd_entries) to some member of
MOVStreamContext, and overwrite the codec id only when the format is 'encv' or 'enca'
please let me know which one you prefer, and I will update the patch.
