Description
Summary of the bug:
sending mjpeg stream from webcam results in broken jpeg frames at receiver.
I record video from webcam like this:
% ffmpeg -loglevel debug -f v4l2 -input_format mjpeg -framerate 25 -video_size 640x480 -i /dev/video0 -vcodec copy -f rtp "rtp://127.0.0.1:5004"

ffplay displays an image with just about the top two lines. I also have this problem in a C program using libavformat with a Qt GUI displaying the frames. I can successfully display the frames before they are encoded in RTP packets (recording from the webcam works fine), but after reception, the frames are broken. Same visible output when displaying the RTP stream with vlc.

@runge_mar: I wanted to work on this bug - but I am not able to play the original file with ffplay. How have you recorded this samplevideo.mjpeg? (which tool and parameters?)

I believe this is a duplicate of ticket #3823, only yuvj420p is supported.
comment:4 by , 9 years ago
@thovo: oh, that was five moths ago. I think I just saved the webcam's mjpeg stream to a file like this:
ffmpeg -f v4l2 -input_format mjpeg -framerate 25 -video_size 640x480 -i /dev/video0 -vcodec copy samplevideo.mjpeg
ffmpeg does not seem to support yuvj422p, but some webcams produce it in hardware.
Note:
