Hi,
I was wondering if there was a reason why supported pix_fmts are
rarely seen when calling `ffmpeg -h decoder=$codec`. I did a quick
audit and it looks like pix_fmts are declared in the help section of
some decoders (see below), but for the most part it is left out.
One benefit that I could see

Hi,
I see that uncompressed RGB is not supported within MXF. I know that
Resolve can create 10-bit RGB but only at HD resolution. I didn't see
anything relating to uncompressed RGB in the UL list in mxfenc.c and I
don't have an SMPTE account to get beyond the Paywall that would let
me know what RG

I should have proof-read better. I have many typos in here, but the
worse is my broken command where I said -ar 2 instead of -ac 2
Also I meant to say that I wasn't sure if downsampling will increase
the volume levels, as I don't know enough about audio .

Cool. I don't know much about x265 and bt2020, but I think the issue

just the tail of the file that's affected? My worry would be that audio
frames might be dropped if the timestamps are being messed with, but

Hi,
When I burn in srt subs using a xyz12le jpeg2000.mxf from a DCP, I get
multiple 'Color conversion not implemented for xyz12le' errors. Even
if I specify that I want white subtitles, I end up getting
transparent, multicoloured subs. It happens with prores as well.
There are no warnings display

It is indeed XYZ. However when I transcode the DCP to libx264 without any
filtering and the output file is yuv420p, the colorspace filter still

Hi,
I only noticed this when it was flagged in the new framemd5 output
that includes SAR values.
A .mov source with no SAR/DAR information (listed as #sar 0: 0/1) in
the framemd5, has specific SAR information when remuxed as mkv (#sar
0: 1/1). Obviously these values are also available via ffmpeg
This is the only scenario that I've ever seen a different starting
DTS/PTS (seen in framemd5) after doing a stream copy from quicktime to
matroska.
I don't know enough about DTS and PTS to know how serious this. I
never encounter it usually, but it would be preferable to retain these
values when s

Hello,
I posted a similar issue recently where an unknown SAR was declared as
1:1 when stream copied to matroska.
I think this is a different issue because the SAR is declared in the
source in this instance. I am running some tests on the xiph/derf
collection and found that a lot of the videos ha

Hi,
My input file was generated from Avid Media Composer 8.
Link: https://www.dropbox.com/s/yed44wj5lq9jg8h/2fr.mov?dl=0
If I use -c copy to remux to mov or mkv, then the lack of
interlacement info is maintained. When I encode with FFV1, using
either MKV or MOV, the file is listed as progressive
