Hi I have a question regarding a command in ffmpeg. I have a relatively high quality video as test.mkv which has a 4k quality and hdr. additionally it has a truehd dolby atmos audio. so lossless and uncompressed. i'm trying to cut the video into small snippets of 5 s now. the background is that i can play this video better as video on demand as m3u8. if i use this : ffmpeg -i test.mkv -f segment -segment_time 5 test%d.mkv the desired result does not come out. ffmpeg turns the audio into sound in vorbis. which no longer offers the quality of a pure atmos truehd sound. but if i just copy the sound and the video with: ffmpeg -i test.mkv -c:v copy -c:a copy -f segment -segment_time 5 test%d.mkv or ffmpeg -i test.mkv -c:v copy -c:a truehd -f segment -segment_time 5 test%d.mkv or ffmpeg -i test.mkv -map 0:v -c:v copy -map 0:a -c:a copy -f segment -segment_time 5 test%d.mkv ffmpeg -i test.mkv -map 0:v -c:v copy -map 0:a -c:a truehd -f segment -segment_time 5 test%d.mkv the sound is not played in all segments. The video is always flawless. My question now is if someone can help me to get these segments to work. because theoretically it is just a copy of everything and always cut off after a few seconds. _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user
