Switching bitrates disables audio?

[hughwhitehouse]

I've been testing this project on some sample media and have noticed the following:
When switching bit rates the audio drops out entirely.

I've qualified that the sample media has audio on all bit rates. Is this a known bug or is there a solution to this issue?

I don't recall having this issue when I tested before. But with that being said, there are a lot of bugs in the current version of this code. It's entirely possible that the audio issue does exist.

We've been investigating the issue and may have found a root for the problem: Does the HLS-AS handle a change in audio bitrates between different streams? i.e Stream 3 is 64k and stream 4 is 128k? Or are there any advised audio settings the HLS-AS can decode?

That’s a good question. I actually do not have an answer for it. I did not write the code that parses the TS files, so I am not sure if the multiple audio bitrates are handled. The TS file parsing is from an older OSMF plugin that was abandoned on google code.
