Thank you for your help! The fact is taht when using hardware encoder and you set mux rate to 20Mbit/s and video to 2Mbit/s the space between 2 Mbit and 20 Mbit/s will be filled with null packets, this is not in this case. Now I reduced Mux rate and it is not exceeded by the tests I did with TS

Dear All, I've been trying to achive constant video bitrate for mpeg-2 with different settings of ffmpeg (windows) but no success. The source was dshow. I've been testing video bitrate with TS reader. Can you tell me if video CBR in MPEG-2 is possible or not and if yes can you send me the
