My eventual goal was to try to add the 'Display aspect ratio : 16:9' attribute to the video stream metadata (otherwise the video is half height) but obviously that can't happen until the video stream gets copied. If I specify anything other than copy after -c:v then it works but it is too slow to use in real time. I get all the audio streams but no video. Even using a syntax that specifically maps the video stream, such asįfmpeg -i infile.ts -c:v copy -map 0:0 -c:a copy -map 0:1 -map 0:2 -map 0:3 outfile.tsĭoes not help. No matter what I do, ffmpeg will copy the three audio streams with no problem (verified by using mediainfo) but it refuses to copy the HEVC video stream, even though it acts like it is doing it. The computer has the latest AMD drivers (22.3.Trying to use ffmpeg to do a real-time stream copy of a stream that contains a HEVC video stream and three audio streams.

I decided to write a program to connect multiple videos and audio.
