           Summary: mpegtsdemux: Audio & video streams mixed up for Apple
                    sample HLS stream
    Classification: Platform
           Product: GStreamer

            Status: UNCONFIRMED

When playing Apple sample HLS stream with mpegtsdemux, video is pushed out on
the audio pad and vice versa after hlsdemux switches to a higher quality stream
Ensure good bandwith, and run this example pipeline. It starts off OK but fails
to detect the new stream mapping and audio and video streams are mixed up. In
the example run below it happens after 0:00:40.

It's even more clear if aacparse is used to parse the audio stream, it fails
and sometimes segfaults when attempting to parse the video stream as audio.

Reasonable behavior is newly added pads when the input stream changes.
