Hi,
Is there a way for my to input my mxf file and grab the meeting to create a
user preset?
Currently, the wizard can only allow video passthru but not audio. I would like
to have a preset base on my approve mxd file.
Thank you
Chan

Right. I was under the impression that TB was not always available in
setpts because I tried the incorrect formula 'N*TB" on a short video and
I obtained pts=0 in all the frames. I forgot that TB is typically a very
small value and that the pts is rounded down to an integer value. Facepalm!

The documenation to setpts says that the FR value may is only defined in

If its does not exists in your mpeg file then you could try something
like 'setpts=N*30'

In your ffmpeg output, all frames have the same time=26:19:06.00 and
that could indicate an overflow in the PTS (presentation time stamp)
values probably because your video is part of a very long video stream.
Add the filter showinfo to your command.
ffmpeg -i input.mpg -vf

Hmm, alright. That's very clear.

Really? That is strange because your original log seems to indicate that
mutiple frames are decoded.
Did you try to generate a raw file instead of using a pipe as shown in
my first comment?
If so, what is the size of that raw file and can you successfully
inspect its content using the ffplay

Usually number of inputs is limited by your memory and not by number of pads,
as that can be very high 31bit number.

The output of
ffprobe -show_streams -show_format -show_packets -show_frames FILE
would be the next best thing. You can add "-of compact" and trim similar
lines if there are.

Whatever filter is being used, this has me curious what the limits of a filter
chain are in terms of number of in/out pads, if any.

Hi,
We're working on a project to have a highly parallelized video rescaling
pipeline but we're finding that small audio and video jumps are being
introduced into the video when we put the video back together. Can anyone
point out anything we're doing wrong?
The pipeline has 3 stages. First we
Hello ffmpeg-user,
About 7 years ago I've used Audacity to assemble the soundtrack of the
videogame No One Lives Forever 2. See

The soundtrack comprised of lots of small segments that can all dynamically be
loaded by the videogame.

This is more of an x264 question than an ffmpeg one, but if I were to guess
they changed the parameter name at some point because, like, what does
psz_cqm_file even stand for, right?
Dear Sir,
As referred by Moritz below command is working fine for FFmpeg 4.1
-x264opts cqmfile=filename
I would like to know the difference between psz_cqm_file and cqmfile.
From notes I got
/* JM format reads the external quantization matrix file in JM format,
automatically ignores other -cqm
In my previous comment, the change of framerate is done during the
transcoding to raw yuv which could be problematic with your mpeg
stream. An alternative could be to convert all frames to YUV and then
drop some of them during the second transcoding. Of course, the
intermediate raw file
I am no expert but something is obviously messing up with the frame
number (a bug in ffmpeg?)
So looking at your dump, it seems to me that the frames are produced
correctly except that they all have the frame number 1.
A solution to your problem could be to drop the frame information by
