It supports the most obscure ancient formats up to the cutting edge.

Thanks.”įor most people who watch movies a lot and do conversions frequently, FFmpeg is widely known to them.
Can anyone help me? Please show me how to extract audio from video using FFmpeg in detail. Could not write header for output file #0 (incorrect codec parameters ?): Invalid argument’. Exactly one MP3 audio stream is required. But it fails and says ‘ Invalid audio stream. I tried to use the following command: ‘ffmpeg -i video.mp4 -acodec copy -ss 00:30:00 -to 00:60:00 extract.mp3’. Stream #0:2(eng): Video: prores (Standard) (apcn / 0圆E637061), yuv422p10le(tv, bt709, progressive), 1920×1080, 170018 kb/s, SAR 1:1 DAR 16:9, 29.97 fps, 29.“How can we extract audio from video file (MPEG-4 format)? From other questions about this topic I learned that ffmpeg is a right tool to do this. In the original file there are 4 empty streams.įfmpeg -i Video1.mov -i Video2.mov -map 1:0 -map 0:1 -map 0:2 -map 0:3 -map 0:4 -map 0:5 -map 0:6 -map 0:7 -map 0:8 -map 0:9 -map 0:10 -timecode 24:10:43 18 -c copy New_Video.mov The original has 11 streams, the new file had 7. But these empty streams don’t copy over to the new file.
When I replace the stream and copy it a new file, it produces a playable file with streams in the correct order, but in the original there are blank streams that the proprietary muxing software I am using needs to see in order to work. Does anyone know of a way to force ffmpeg to copy empty video streams? I have a video file from a ProRes recorder (Odyssey 7Q+) that has a corrupted vidoe (stream 0).
