#12807 closed Bug Report - General (Unverified)
HLS encodes audio in video segments

Description
HLS specs out the audio/video segments separately. The MythTV .av files contain the audio track as well. This would seem like a slight overhead waste. Before trying to fix it I figured see if there was any legitimate use for this.

dekarl commented that he thought audio separate streams may have been new in 1.4. It is supported in older (specifically mentioned in 1.3 http://tools.ietf.org/html/draft-pantos-http-live-streaming-13) with older ones still supporting alternate audio streams (back to 1.0 http://tools.ietf.org/html/draft-pantos-http-live-streaming-10).
I guess maybe it is best to remove the audio-only stream from the playlist? As mythtv doesn't support multiple audio/video bitrates encoding the audio in the video file and not providing a second audio only track does not seem detrimental (this also would explain why some clients show two audio tracks for HLS live streaming).
If we want 100% back compat it could be a flag in the initial AddLiveStream? request.
