Dear all, Now we are writing up a media demux element. It contains one sink pad and two source pads (audio & video). The element is expected to contact to next stage element (codec) in PUSH mode. After processing data in chain() function, we call gst_pad_push to send the audio or video to peer pads in codec elements (H.264 video or AAC). a) gst_pad_push returns back with 0 which looks successfully for video data b) gst_pad_push always return back with -5 for audio data. Actually we use same codes (but names) to finish the above actions, however we got different results (o or -5). Would anyone of you tell me what?s the difference to send out audio/video data to their codec? Thanks a lot! Best Regards!
