ffmpeg built with schannel freezes when outputting HLS with http_persistent

Reported by: r1ch Owned by:

Version: git-master Keywords: hls schannel regression

Description

When outputting HLS to a HTTPS URL using http_persistent, if ffmpeg is built with the schannel TLS backend (Windows), it will freeze as it writes the first segment. Switching the TLS backend to gnutls allows this to work as expected.

How to reproduce (Windows only):

Build ffmpeg with --enable-schannel. Stream some input file to Youtube with the HLS ingest endpoint (or any HLS server of your choice). You must use -http_persistent 1 to reproduce the issue.

% ffmpeg -i "bbb_sunflower_1080p_60fps_normal.mp4" -acodec aac -vcodec libx264 -vb 2.5M -f hls -hls_time 4 -http_persistent 1 "https://a.upload.youtube.com/http_upload_hls?cid=VALID_YOUTUBE_STREAM_KEY&copy=0&file=01.ts"

comment:6 by ushadow, 2 years ago

I can reproduce the same problem with a simple nginx HTTP server with similar setup as in #7975. HTTP works. HTTPS with schannel and no http_persistent on Windows works. But HTTPS with schannel and http_persistent on Windows doesn't work. Compiled ffmpeg from latest snapshopt. Here is the log:

Replying to ushadow:

I can reproduce the same problem with a simple nginx HTTP server with similar setup as in #7975. HTTP works. HTTPS with schannel and no http_persistent on Windows works. But HTTPS with schannel and http_persistent on Windows doesn't work. Compiled ffmpeg from latest snapshopt. Here is the log:

I compiled the current FFmpeg git master with this patch applied and with --enable-schannel. I ran the command in the description and successfully streamed the full test video to YouTube via HLS on Windows.

This seems promising. Hopefully others can test and produce similar results.

That because -http_persistent 1 is default, you can try to use -http_persistent 0

BTW:
Is this problem happened with this ticket? Or should it merge into this ticket?

The patch in comment #comment:9 has solved the issue on our end.

Comment #comment:11 seems to be discussing issues with HLS input, I don't believe this is relevant to this ticket as the issue and patch only relate to HLS output.

Looks like the patch works. Is the patch going to be merged to Ffmpeg?

Maybe you should build with openssl 3.0 that is finally compatible with gpl.

Yes, the patch should be merged if you will again confirm it works.

The patch provided above is for fixing HLS output. The test case in this ticket is about outputting from FFmpeg to YouTube. You seem to be talking about HLS input by ingesting a playlist from some external source into FFmpeg. Your described scenario seems to be unrelated to the described scenario in this ticket or to the patch provided above.

Unfortunately, I'm not sure when I'll have time to rebuild FFmpeg and retest this. The ticket author and I did confirm earlier in comment:10 and comment:13 that the patch resolved the issue we're experiencing, however.
