Send additional parameters for extract audio (ffmpeg) to add ID3 tags.

[andrewfree]

Is there a way to send more parameters to ffmpeg when it converts a video to mp3 file because I would like to add params to write ID3 metadata tags.

I would also support this if does not exist already.

In the next release (or with the version from git) you can add the metadata with the --add-metadata option, for example: youtube-dl 'http://www.youtube.com/watch?v=BaW_jenozKc' --add-metadata, will add it to the video file, if you extract the audio with youtube-dl 'http://www.youtube.com/watch?v=BaW_jenozKc' --add-metadata -x it will also be added to the audio file.
Currently it sets the title, date and author.

Awesome! That will be helpful. I was just using the id3v2 library and python like this in the meantime.

process = subprocess.call(["id3v2","-t",title.strip(),"-a",artist.strip(),"--COMM",downloadSource,os.path.abspath(fileName)])

These changes have been added to youtube-dl 2013.10.17 and newer. Type sudo youtube-dl -U to update.

I updated and am now running youtube-dl version 2013.11.22.2. But when I run the suggested command on the suggested file, I get no id3 tags. After digging a lot I found out how broken the world of m4a tagging is (http://askubuntu.com/questions/364415/is-there-a-command-line-program-to-read-tags-from-m4a-files) and I see that there are tags there, so that's good.

But when I add --audio-format mp3 to get a better-standardized file, I get no tags. Can id3 tagging be added also? Thanks!

@nealmcb Normally, ffmpeg should just copy the ID3 tags.

$ youtube-dl --add-metadata -x --audio-format mp3 BaW_jenozKc

Can you create a new issue where you describe precisely what you are running (the output of youtube-dl, if possible even when called with -v), what version of ffmpeg you have and how you are checking for ID3 tags?

[nealmcb]

Thanks for the quick response! It looks like you're right, and the issue is with the id3v2 program.

When I did my original copy-paste from the command line and hit "Comment", I got this error from github:
"There was an error creating your comment: Body contains unicode characters above 0xffff"
so I've removed some of the file name characters below. (That's quite a file name for youtube-dl tests, and it made me wonder what was going on for a while. A simpler name for this sort of testing might be better.)

$ id3v2 -l youtube-dl\ test\ video-BaW_jenozKc.mp3
youtube-dl test video-BaW_jenozKc.mp3: No ID3 tag

$ eyeD3 youtube-dl\ test\ video\BaW_jenozKc.mp3
...
ID3 v2.4:
title: youtube-dl test video artist: Philipp Hagemeister
...

And mutagen-inspect and exiftool also find it.
So this seems to be an issue with id3v2 (version 0.1.12-2, on Ubuntu Precise 12.04)
