Specfying "^=" ("begin with" filter) in format selection doesn't seem to work

[mzso]

Hi!

I get this:

youtube-dl --ignore-config -f bestvideo[vcodec^=avc]+bestaudio -o teszt.%(ext)s https://www.youtube.com/watch?v=Zpyxuf30pYc
[youtube] Zpyxuf30pYc: Downloading webpage
[youtube] Zpyxuf30pYc: Downloading video info webpage
ERROR: requested format not available

I have no idea, why wouldn't it work. It works with exact format codes such as vp9 or avc1.640028. So the filter fails I guess.

Format list:

Well, I was using the latest exe it updated to (2018.10.05) and not a python script. So that's a difference:

youtube-dl -v

Using exe makes no difference.

IIRC ^ (caret) is a special character that allows to continue a command on next line.

Instead of
-f bestvideo[vcodec^=avc]+bestaudio
try this:
-f "bestvideo[vcodec^=avc]+bestaudio"
or
-f bestvideo[vcodec^^=avc]+bestaudio
