Well, finally I've written that code. Using the decoding time to calculate the bitrate of the PES stream, the audio bitrate is perfectly constant, but the video's does not look constant at all. Plotting the result with xgraph you can see a saw with sharp teeth. I'm not sure if this is the correct way to see the bitrate of a PES stream, (maybe delving into the 13818-2 standard is required) but the results agree with yours. Best regards -- Samuel
