Using git HEAD, here's the full output of using "-ss 0.333" which seeks much
less than 0.333 seconds into the file:
$ ffmpeg -ss 0.333 -r 24 -i color-frames.mp4 -r 24 colorout4.mp4

Hi,
I have learned, that ffmpeg respects a given tbr value as output frame rate.
Now I'm questioning the advantage of that behaviour. Can someone tell me?
I only see disadvantages:
- the video becomes encoded with lower quality, i.g. q=33.0 instead q=29.0
- the video size is 13 % bigger, e.g. 5

I guess you could use the -r option to override this and force a
specific framerate if you want something different?
Yes, this works fine. But I would appreciate, if I could use something like
-r=inputrate or --keep_framerate
I've found out, that using

Probably not, you're telling ffmpeg to do different things.
You're also missing the complete command output from each command.

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

AV1 has no keytimes. That's what I call it because I don't know what else
to call it. It works with the other known codecs. I can jump back and
forth in the video, but AV1 always goes back to the beginning.
Can you do anything with FFMPEG?

Hi,
is it possible to convert the waveform of an entire audio file (or a
segment of it) to a picture?
The "showwavespic" filter has the problem that for each sample it draws
a line from +level to -level. For example, if the input is a +0.5 DC
signal, I can't decide from the output picture if t
