Allow ffmpeg/ffplay to have a boolean flag to use different hosts crossdomain in m3u/hls/m3u8 feeds (Cannot reuse HTTP connection for different host)

[dejavuyeah]

Before I start, I would like to inform that I have scoured every single resource i could get my hands on (google, ffmpeg docs, this sub, superuser, stackoverflow...) and the fixes are either nonexistent or wouldn't work.

I have an m3u file that looks like.. (hypothetical urls)

#EXTM3U

#EXTINF:-1,https://cdn461.example.com/hooligan.mp4
https://cdn461.example.com/hooligan.mp4

#EXTINF:-1,https://cdn329.example.com/poker.mp4
https://cdn329.example.com/poker.mp4

#EXTINF:-1,https://cdn907.example.com/damnation.mp4
https://cdn907.example.com/damnation.mp4

And the ffmpeg cmd: ffmpeg -re -protocol_whitelist "file,crypto,data,http,https,tcp,tls,rtmp,rtmps" -f hls -http_persistent 1 -http_multiple 0 -i "https://example.com/different_hosts.m3u8" rtmps://chopsuey.net

After streaming of the first file FFMPEG would then yield an error...

ERROR:

[https @ 000001a8f763bb00] Cannot reuse HTTP connection for different host: cdn461.example.com:-1 != cdn329.example.com:-1
[hls @ 000001a8f5775bc0] keepalive request failed for 'https://cdn329.example.com/poker.mp4' with error: 'Invalid argument' when opening url, retrying with new connection
[hls @ 000001a8f5775bc0] Opening 'https://cdn329.example.com/poker.mp4' for reading

After successfully he rtmps feed would then be frozen, with ffmpeg seemingly not feeding any data to the rtmps feed. the FFMPEG process is not frozen or have crashed, it would simply not output once it detects the second file which has a different domain.

When setting http_persistent to 0 and http_multiple to 1 ffmpeg would stop streaming output to the output file.

It seems like ffmpeg does not work with m3u8/hls files that have cross domain sources and there is no option to force it to use different connections for each file. Similar issues are well documented:

How to reproduce:

This is easily reproducible by creating an m3u file that directly links to files that have different domains (working urls).

#EXTM3U

#EXTINF:-1,http://cdn001.fr.to/001.webm
http://cdn001.fr.to/001.webm

#EXTINF:-1,http://cdn002.fr.to/002.webm
http://cdn002.fr.to/002.webm

#EXTINF:-1,http://cdn003.fr.to/003.webm
http://cdn003.fr.to/003.webm

(A copy of this file is located in ​http://master.fr.to/)
And by running said m3u to passthru an rtmps server or a local file. I have not tested the local file method but it should also produce a ftile consisting the first video only. I will further test the issue and alter this post whenever needed.

Amendments:

This is also an issue in ffplay.

ffplay -f hls http://master.fr.to/
