Description

Not sure if limited to just youtube or how far it extends, but with the latest version of yt-dl and the ---embed-thumbnail option (along with -x --audio-format mp3 which I'm guessing is inconsequential), both the mp3 and jpg are downloaded with identical filenames except for extension, however it looks like when the script is trying to embed the thumbnail it's getting choked on the single quotes in the title of the thumbnail image.

For reference the quotes that it choked on are U+2018 and U+2019 (not the U+0027 that is more commonly used in the US)

Most likely avconv issue not supporting file: prefix properly.

[minig0d]

Is there a suggested fix/workaround then?

[dstftw]

Use ffmpeg obviously.
