Tiled image on each key frame

[ralf.butler]

Dear All,

I record with vlc:

Code: Select all

cvlc --color --run-time=10 v4l2:///dev/video0 :v4l2-adev= :v4l2-standard=0 :sout='#transcode{vcodec=mp4v,vb=800,scale=1,acodec=none,sfilter=marq}:std{access=file,mux=mp4,dst=/tmp/out.mp4}' --sub-filter marq --marq-marquee \"%D %H:%M:%S\" --marq-position 6

When replaying the footage each key frame is tiled (I don't know the exact wording for this kind of effect).
This is how a floor looks like when I record it:

But it should look like this:


With each frame after the keyframe the quality is getting better. But as soon as the next keyframe appears I see a tiled image again.
Any suggestions are welcome.

Increase the video bit rate ro decrease the frame rate.

Hi Remi,

I would like to keep the frame rate. I hope a video bit rate of 1000 will do the job.

Thanks,
Ralf
