[FFmpeg-devel] Separate stream for subtitles in HLS?

[David Johansen]

Currently, I have to put the subtitles on the video stream and when I make
the subtitles their own stream, I get this error:
No streams to mux were specified

Would it be possible to have the subtitles as their own stream or is too
engrained of an assumption that there's an output stream tied to each of
the streams? (this appears to be from the call to avformat_init_output)

Thanks,
Dave
