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.
