Hi, is there a way to extract the information about the timebase of a timecode in an audio file, like you can find in the wild e.g. in MXF or in Mov files? I can see that ffmpeg apis and thus ffprobe expose the timecode as a string-valued tag (e.g. TAG:timecode=00:00:00:00) but the information

Thank you for the answer, how would I calculate the correct audio PTS with respect to video stream? As for the intermediate audio file, unfortunately I can only request the file to be delivered to me in this (MPEG-PS, both video and audio streams) format. George A. -Original Message-
