CEF Hang streaming audio with custom CefResourceHandler

[scratchdisk]

CEF 35.0.1916.138

I'm seeing an occasional hang when streaming several ogg files. I've tried everything I could think of with my CefResourceHandler implementation. Here is the possible callstack. Any ideas?

Are you handling Range headers?

Are you handling Range headers?

Great thought, but it happen even if there are no partial requests with "Range" made.

Thanks

Try running with `--enable-logging --v=1` command-line flags and check the debug.log file to see if that sheds any more light on the problem.

Thanks for your quick reply, there are indeed several curious errors of this type:

[0910/152540:ERROR:audio_file_reader.cc(192)] Truncating decoded data due to output size.

and

[0910/152616:ERROR:command_buffer_proxy_impl.cc(540)] Failed to Initialize GPU decoder on profile: 11
