Ah, it's actually an HLS playlist, which means the audio is in
fragments. adaptive demuxer elements (like hlsdemux) will expose a new
srcpad for each fragment, and you're supposed to use input-selector to
switch from one pad to the other to have continuous playback. You can
reproduce the same issue with:
! audioconvert ! audioresample ! queue ! autoaudiosink
You should just use playbin instead of decodebin here, since it will
handle all this for you:
You can set the "audio-sink" property to a GstBin that does
`audioconvert ! audioresample ! vorbisenc max-bitrate=64000 !
rtpvorbispay name=pay0 pt=97` and expost ghost pads for the sink and
Basically you need to write C code to make this work with
gst-rtsp-server, you can't do it from the command-line.
