Changing, to block 124353 , as it is a meta bug. Increasing this limit is just a workaround though :( I keep wondering if we should investigate building our own audio-sink that would maintain a single connection with PA, whatever the number of media elements present in the page... Sebastian suggested to have one pipeline for audio playback maintaining a single connection to PA and then for each playbin pipeline set the audio-sink to connect to the audio playback pipeline using the "inter" elements. The playback pipeline would also have an audiomixer to combine all incoming audio streams to one, IIUC.

This was done in https://bugs.webkit.org/show_bug.cgi?id=207634 BTW. (In reply to Philippe Normand from comment #4) > The playback pipeline would also have an audiomixer to combine all incoming > audio streams to one, IIUC. Same. To enable the mixer, set WEBKIT_GST_ENABLE_AUDIO_MIXER=1 at runtime. |
