How to handle EOS from an appsrc to ensure all frames are played out before pipeline closes?

[Sébastien FENET]

Thanks, Jan, for the tip.

As far as I am concerned, I use the Python API. In this API, there is no "gst_app_src_end_of_stream". Instead I use emit("end-of-stream"). But according to the documentation, it has the same effect : 

"When the application is finished pushing data into appsrc, it should callgst_app_src_end_of_stream() or emit the end-of-stream action signal."
I may be wrong but I made some testing a while ago and I had the impression that it was rather the audiosink that emits the EOS signal on the bus before draining its queue.

How are you sending the EOS? You should use gst_app_src_end_of_stream,
not gst_element_send_event or similar.
The latter can send the EOS event before appsrc has completely drained
its internal queue.
