Description

When i try to download all videos of a channel via youtube-sync i get the error "Conversion failed!" at the step "[ffmpeg] Embedding subtitles in 'SYNC/PursuitofWonder/ID/oGVhOWqsBWM.mkv'". Is this error youtube-dl or ffmpeg related? How to fix this?

The url of the video is https://www.youtube.com/watch?v=oGVhOWqsBWM and the quality setting i use to download is "22/136+bestaudio[ext=m4a]/bestvideo[height<=720]+bestaudio[ext=m4a]/best[height<=720]"
