Description of my issue:

Happens when I try this URL: https://www.youtube.com/watch?v=2tN875A3Bj8
with these options: --continue -o - {url}

Any idea why?
And why is the download speed so low (30KB/s)?
(Using C#)

People?

Most likely network issue on your side.

And why is the download speed so low (30KB/s)?

Cause you are streaming to stdout and consume with ffmpeg at playback bitrate.

That's a no. it happens to me and a friend of mine. @dstftw

@NoamHerry : try without piping to stdout to isolate the download speed from the ffmpeg transcode speed. This might be the issue here as was suggested.
