The audio included formats are only three (on the bottom), really bad choice to choose from, i wanted webm video 720p VP9 with audio. Unsure if issue is on my side or on YT not providing it?

Windows 7 Ultimate 64bit, i am not aware i installed any codec pack.

Instead of manually fucking around with the format codes, use format specifiers:

If you don't want the highest resolution, specify that in the specifier, like this:

--format "bestvideo[height=720]+bestaudio/best"

This'll choose the best vid with the height of 720p (commonly 1280x720 but there are other, rare, instances) and the best audio, then uses FFmpeg or avconv to combine them (you've to specify the location). If that fails, it'll take the best present option which had both vid and audio, in this case the format code 18 in your output.

In YT they don't store high-resolution combinations of best vid and best audio, but in separate parts. That's a godsend to us although it requires combining them locally.

Dunno if your other options will play nicely with this; I imagine FFmpeg will convert the audio and/or the vid.

@rautamiekka @dstftw @ALL

--format "bestvideo[height=720]+bestaudio/best"

Thanks for detailed explanation. The result was:

E:\Other\Software\Youtube-DL>youtube-dl.exe --format "bestvideo[height=720]+best
audio/best" https://www.youtube.com/watch?v=gl1aHhXnN1k

(It ended up the audio is .webm and video is .mp4)

So ffmpeg/avconv is not bundled in youtube-dl.exe? Can it be bundled for more easy to use?
I need to be searching some third party software to install codec packs for me?
How do you do it to make YT-dl to combine files?
I am on Windows 7.
