need_data and enough_data don't work properly caused by sparse stream

[haykav]

Hi experts,

pipeline contains video-appsrc and many audio-appsrc connected to audiomixer and their streams eventually are connected to mp4mux. For some time-points i have audio-gaps(no audio-buffer) and video-appsrc doesn't send need_data signal but only enough_data. i tried to send  gst_event_new_gap to audio-appsrc but in any case the video-appsrc doesn't send need_data until i send audio-buffers.
How can i solve this problem?

Thanks in advance
Hayk

Hi haykav,

There may be a possible deadlock. Can you add a queue just before the audio and video encoder, set it to leaky. Check if it helps.

Hi Vinod Kesti,

Thanks for your response.
I've added queues before the audio and video encoders and set it to be leaky, the pipeline works but there are buffer-drops and we are not get desirable result :(

Best regards
