Append metadata title during encoding

[ghost]

Here is a suggestion: an option (toggled on by default if possible) that copies the filename and uses it during the video encoding to add a metadata title. This is useful for those video that lost the original name title. Thanks to this you can track down the origin of a file even after multiple encoding since the metadata title should be preserved even after additional encodings with ffmpeg. Right now I have to do this with a bash script like this:

filename=$(basename -- "$i")
tempname=${filename%.*}_tmp.${filename##*.}

mv "$filename" "$tempname"
ffmpeg -i "$tempname" -c copy -metadata title="$filename" "$filename"
rm "$tempname"

but I would rather do the job during video encoding so I don't need to make and remove useless temp files

Duplicate of #12, although he closed the issue when he wrote his own code for that.

I still kinda doubt the usefulness of this, but I'll do it anyway. Soon(tm).

[ghost]

Thanks. Now that I'm thinking about it this shoukd be set off by default or it will affect other people who dont want to edit their metadata at all

[ekisu]

@leewdch I also think off by default makes more sense. Try it out.

I tried the script but the encode fails and it asks me to check the logs. I didn't find logs in my home, source directory or in my mpv config directory

[ekisu]

Please run mpv in the console with the -v and post the output, or add the log-file=log.txt line to your mpv.conf and upload the resulting log.txt file (it will be in the same directory as the video file you're watching).

I need that you try to encode something and trigger the error, so that I can examine the logs.

Is your mpv updated? This was added quite some time ago.

switching from mpv to mpv-git in the AUR fixed the issue
