To create a constant rate transport stream with ffmpeg, you have
to use the -muxrate parameter. The video stream does not have to
be CBR. However, the peak video rate plus the audio rate cannot
exceed the muxrate.
BTW, w6rz.net is my website. Most of the main page streams are
muxed at the ATSC rate of 19.392658 Mbps.

Dear all,
We are a team of engineer students, working on a ISDB-T Digital TV Transmitter for GNU-Radio.
To test the TX, we need to create constant bit rate transport streams that are compatible with the ISDB-T standard.
Currently we are working with ffmpeg to transcode the videos that we want to send, but we are having some issues with the receptor, and we suspect that the videos that we are transcoding with ffmpeg are not constant bit rate videos.
We found the webpage http://www.w6rz.net that has some CBR samples taken out from DVB-T trasmissions.
Does anyone know how were those samples generated to mantain a constant bit rate?
Thank you!!
