To save space on my NAS, I did compress some of my smartphone videos lately using this command:
ffmpeg -hide_banner -y -i in_filename -map 0 -map_metadata 0 -c copy -c:a libvorbis -q:a 4 -c:v libx264 -crf 23 -preset slow -max_muxing_queue_size 4096 -movflags +faststart out_file.mp4
This worked flawlessly, copying over all data streams and metadata, and compressing video and audio with the specified codecs. Unfortunately, as vorbis is not officially supported in the mp4 container, some player will not play the sound on those files. So I wanted to remux the files, for which I still have the originals available using:
ffmpeg -hide_banner -y -i original.mp4 -i compressed.mp4 -map 1:v -map 0:a -map 0:s? -map 0:d? -map 0:t? -map_metadata 0 -c copy out.mp4
This should
- take all video streams from the compressed version created by ffmpeg
- take all audio streams from original
- take all subtitles, data, and attachment streams from orignal
- take all metadata from the original
However, the conversion fails with error
Could not find tag for codec none in stream #2
As I already did use this file to create the compressed version, I am puzzled why I now get a codec tag error here. Also using -copy_unknown, or -ignore_unknown does not help.
When trying my original command again, I also get this error, so I really wonder, how did I create the "compressed" file in the first place. It must be possible...
Codec information on the "original" and "compressed" file:
Stream #0:2(eng): Data: none (urim / 0x6D697275), 38 kb/s (default)
Stream #0:2(eng): Data: none (stts / 0x73747473), 38 kb/s (default)
FYI: I wanted to remux the existing compressed video and original audio to speed up the process and prevent generation loss. As an alternative I could work on the original file or the compressed and encode only vide or audio respectively. However, as it currently stands I cannot work on either file without losing the "data" stream, which I would like to prevent if possible.
Any inputs?
If it helps, here the complete outputs:
ffmpeg -y -i original.mp4 -map 0 -map_metadata 0 -c copy -c:a libvorbis -aq 4 -c:v libx264 -crf 23 -preset slow -max_muxing_queue_size 4096 -movflags +faststart out.mp4
