Description

From 10/July/2019, some live streaming on youtube upgraded their format, for example: "https://www.youtube.com/watch?v=KTJXlMnA1c0", with separate video and audio.

When using:
youtube-dl -f 136+140 "https://www.youtube.com/watch?v=KTJXlMnA1c0"
or even
youtube-dl -f 136 "https://www.youtube.com/watch?v=KTJXlMnA1c0"

It will only download a 500KB mp4 file with no sound. I have changed networks and checked with browser in the same network condition, and confirm it isn't caused by network fault.

its the same here, when we do youtube-dl -f 136 -g "youtunbe-link" it gives something strange. Youtube moved the live transmission from HLS to DASH and i dont find the way to get the MPD manifest to passthrough to ffmpeg yet. In the past i used youtube-dl to get the m3u8 links and download with ffmpeg hls demuxer. FFmpeg has a dash demuxer but you need to give him the MPD manifest.
