Twitch VOD download freezes indefinitely

[buchno]

Some newer Twitch VODs cannot be downloaded. The first few seconds go fine, but then the download freezes indefinitely.

According to livestreamer issue #1340, this may be because of a missing playlist endtag.

Edit: oh, you fixed it already. This issue can be closed.

This is ffmpeg issue and should be reported to them.
In the next version native hls downloader will be used for vods instead of ffmpeg.
