Description of your issue, suggested solution and other information

When attempting to download the video in question, the downloader warns that the formats are incompatible to merge and downloads 2 separate files, and mp3 and a webm

The MP4 file seems to be OK as its playable in VLC but does not have any audio

But VLC can't play the webm file (which I presume is supposed to contain the audio), and ffpmeg is also unable to process the webm

The webm file does seem to contain data, and looking in a hex editor it has
google/video-fileWA‘google/video-file. in the header block.

I get pretty much the same error on Linux Mint, as when using the Windows exe.

I don't know if this is a problem that ffmpeg can't decode the webm file or possibly the incorrect file is being download as the webm, I suspect the former.

Outdated ffmpeg.

[rogerclarkmelbourne]

Thanks.

I had to compile ffmpeg from source in order to get it to work, as doing a dist upgrade on Linux mint didn't seem to give me a new enough version.
