How set limit to output bandwidth

[erotavlas_turbo]

Hi,

I know the vb parameter is used to set the output video bandwidth. If I try to set vb=100, the output video always requires 350 kbps. Why?

These are my command line parameters

Code: Select all

vlc image.jpg --sout '#transcode{vcodec=H263p,fps=1,width=352,height=288,vb=100,acodec=none}:duplicate{dst=rtp{dst=195.223.177.46,port-audio=11318,port-video=16444}}'

Thank

Not all encoders implement all bit rate values.

Ok, so only H264 implement bit rate variable. Where can I find the bit-rate value for H263p?

The H264 codec implements VBR very well. I can set through the vb parameter the bandwidth value and the video changes accordingly. The H263p doesn't care about the vb parameter. If I try to change vb the results don't change. Is this a implementation choice?

You'd have to ask FFmpeg people if you want to know about their design choices.

How can I use FFmpeg encoding parameters inside VLC?
