Full command line is in the log. Probably any HLS inputs and similar filter will work.

What was tested:

• master with --enable-gnutls
• master with --enable-openssl
• different HLS demuxer options: http_persistent, http_multiple, http_seekable and probably more
• high thread_queue_size seems to resolve the issue, but only because in some cases whole streams are cached in the memory and no http requests are made after initialization
• different providers (local files are working correctly)

With openssl error is slightly different:

but the result is the same - output with broken audio and video.
