FFMPEG 处理 MOV 文件时失败

Question

I'm trying to convert video files to DASH format. All videos work great except MOV videos.

I'm using the following command:

/usr/local/bin/ffmpeg -y -i /path/to/mov/video.mov -c:v libx264 -c:a aac -bf 1 -keyint_min 25 -g 250 -sc_threshold 40 -use_timeline 1 -use_template 1 -init_seg_name 'video_init_$RepresentationID$.$ext$' -media_seg_name 'video_chunk_$RepresentationID$_$Number%05d$.$ext$' -seg_duration 10 -hls_playlist 0 -f dash -adaptation_sets -0:s -map 0 -s:v:0 854x480 -b:v:0 750k -strict -2 -threads 12 /output/path/video.mpd

I get the error:

• Could not write header for output file #0 (incorrect codec parameters?): Invalid argument... Error initializing output stream 0:1

The full command output is:

Stream #0:2 -> #0:2 (copy)
Stream #0:3 -> #0:3 (copy)

I guess the problem is that the file contains two not audio/video streams: I can not find a way to exclude or ignore or copy without processing those last two streams (#2 and #3).

Answer 1

To fix this problem I had to remove all streams from the video file.

This answer helps me to build the proper ffmpeg command to prepare video file before processing it by the original command https://stackoverflow.com/a/38162168/10561527

Answer 2

No need to prepare the file beforehand.

Only map video and audio

You are using -map 0 which includes all streams. I doubt the DASH muxer works with other stream types such as data (streams #0:2 & #0:3 in your example), subtitles, and attachments.

Change -map 0 to -map 0:v -map 0:a to make sure only video and audio are included.

Your -adaptation_sets is wrong

Remove this option and use the default, or read the FFmpeg DASH muxer documentation to modify it.
