It's possible you'll instead want to use "setpts", which will keep the frames
as-is but re-timestamp the frames.

With the latest git version on Debian, I try and screen record.
My system is set up for 10-bit color, which I assume is the "mapping pixmap
format" issue.
Is anyone working on - or willing to work on - adding support for this pixel
format? It would be very appreciated!
Thanks,

OS: Debian 11.2, latest ffmpeg git master.
I've got a fairly simple filtergraph that's been giving me quite a hard time in
terms of starting or staying in sync. I've boiled it down to a test case with
three input videos, two identical (i.e. the same file), which clearly shows at
least a frame

While reproducing a separate issue, I came upon some strange behavior with the
-ss flag: it seems to be seeking incorrectly when used as an input option in
some cases (including while transcoding and using -accurate_seek). Here's a
reproducer:
wget 'https://0x0.st/-yD3.mp4' # this host
n't know.
Any help here is much appreciated. Thanks!

How are frame numbers converted to and from decimal numbers of seconds in
ffmpeg and related tools?
For example, given a file foo.mp4 at 24fps, when I run a command like:
ffmpeg -i foo.mp4 -t 0.72 bar.mp4
0.72 is a time between frame 18 (0.70833... seconds) and frame 19 (0.75
seconds).
When can I expect the output of ffmpeg to be byte-for-byte identical across
runs given the same input and command-line flags?
When I do simple tests now I always see the same checksums, but I remember
(sorry, short on details) often seeing different results with the same commands
in the past.
Does anyone use ffmpeg (the executable, not the library) for large video edits?
I can imagine taking an edit decision list and translating it to a giant filter
graph of trims and concats, but I haven't seen this done. Is that because it's
an awkward tool for the job? Or is there some upper
