Apologies that my question is hardly related to Ffmpeg. Just trying to tap
into the knowledge of the experts on this user group.

I am dealing with a system that transfers H264 over the internet in the
following way:
We break the encoded stream into frames, then we send individual frames
over the network, then we piece the stream back together.
The problem is that due to inadequate network speed we sometimes drop
frames out
Thanks Gyan, we'll give mp4box a shot.

I am using a somewhat experimental evaluation board to record HEVC video. I
converted the stream to mp4 using this command:
ffmpeg -i input.bin -c:v copy out.mp4
I can play out.mp4, however I see the video skips at some point and plays
at faster-than-life rate at another point.
I think there are
Thanks for your answer Carl.
-skip_frame works.
Too bad "spatial subsampling" is hard or impossible .

I have an USB3 camera module that outputs an MJPEG stream.
I recorded it with “-v:c copy” argument to an avi file.
Now I want to reencode it to a more compact file in h264/mp4 format. If I
do that with default arguments, I get a file with more frames than the
original! Also the FPS – as
rsed a group of options.
Opening an input file: video=Microsoft LifeCam Front.

I’m on a Surface Pro 3 running Windows 10. Trying to record an mp4 from a
native H.264 stream.
The H.264 video sources are on the second “pin” and I suspect that’s the
problem. But the first and second pins have the same name, so I don’t know
how to specify them. I was able to record from the

Thank you Moritz!

I want to copy the original stream without any transcoding or processing.
I'm on Windows. I got this far:
