Hi,
I would like to use a queue to buffer muxed data. My use case is that I need to record audio and video (for a preconfigured time) from before the user activates the recording, so to record pre-event data.
A simplified version of my pipeline:
audiotestsrc ! vorbisenc ! queue ! file_sink_video_mux.
videotestsrc ! nvvidconv ! nvv4l2vp8enc ! queue ! webmmux name=file_sink_video_mux! queue name=file_sink_queue ! filesink name=file_sink location=/tmp/video_out.webm
(Besides that the pipeline has other brancher for live video feedback and streaming, and using real audio and video sources).
And what Im doing on the application side is the I set the queue's 'max-size-time' property for buffering and blocking its pad until the record request arrives, and in theory when the user enables recording the pre event data would come from the queue and after it would be a regular live recording.
My question here is if this is possible to do with muxed data or not (I can do something similar with the queues before the mux but there it would be more complex to do and would affect other parts of the pipeline).
Thanks!
Peter
