Strict Rate Control Problems

Hello,

I am having problems transcoding a input file to a output file with a constant bitrate.

I am using the following vlc arguments:

--intf dummy -vvv input_stream.mpg ':sout={#transcode{venc=ffmpeg{vt=0,strict=1,keyint=12,
rc-buffer-size=4000,strict-rc},vcodec=mpg,vb=5000}:standard{access=file,
mux=ts,url=output_stream.mpg}' vlc:quit

The output stream *has not* a constant bitrate. It reaches 6 Mbps at some moments. I have noticed that videolanclient says that the encoder doesn't understand the strict-rc option. I am using the 0.8.1 version of videolanclient and the ffmpeg codec was compiled from the source that I donwloaded from a link of the VideoLAN homepage some weeks ago.

Thanks in advance.

AFAIK, constant bit rate isn't possible with ffmpeg (or vlc)

What about the strict-rc option?
