What is the purpose of your issue?

- [ X] Bug report (encountered problems with youtube-dl)

Add -v flag to your command line you run youtube-dl with, copy the whole output and insert it here. It should look similar to one below (replace it with your log inserted between triple ```):

$ $ youtube-dl --external-downloader aria2c --external-downloader-args '--min-split-size=1M --max-connection-per-server=16 --split=16 --max-concurrent-downloads=16' -v https://www.twitch.tv/xbox/v/72220716

Description of your issue, suggested solution and other information

When using the arguments as noted, I usually had 16 dl streams through aria2. Now it seems the dl just goes through youtube-dl?

Seems aria2 does not support HLS.

$ aria2c http://vod.ak.hls.ttvnw.net/v1/AUTH_system/vods_3012/xbox_21831886816_469072441/chunked/index-dvr.m3u8

@sheepdestroyer, there is feature request to make HLS possible in Aria2.
