AW: Video saved using mp4mux is not playable in android default media player

[Thornton, Keith]

Hi, do you know if the video is being streamed with stream-format=byte-stream. Maybe with the first pipeline it is being stored to file as byte-stream. If this were the case, a caps-filter after the h264parser, converting the stream-format to avc might help.

Betreff: Video saved using mp4mux is not playable in android default media player

I send video stream using gstreamer using the below pipeline from desktop

    gst-launch-1.0 v4l2src ! video/x-raw,width=640,height=480 ! x264enc !
h264parse ! rtph264pay pt=96 ! udpsink host=ip_address port=5000

and then receive and save the stream using the below pipeline on another desktop 

    gst-launch-1.0 -e udpsrc port=5000 !
application/x-rtp,clock-rate=90000,payload=96 ! rtph264depay ! h264parse !
mp4mux ! filesink location=a.mp4

But when I transfer this saved video to android phone this video is not playable using default media player. But is playable on other media players like vlc or mx player. If I decode and re-encode the stream on the receiver then the saved video is playable on android using default media player. The modified receiver pipeline is as below

    gst-launch-1.0 -e udpsrc port=5000 !
application/x-rtp,clock-rate=90000,payload=96 ! rtph264depay ! h264parse !
avdec_h264 ! x264enc ! mp4mux ! filesink location=aa.mp4

I don't wanna do this decode/re-encode thing. So can you tell me why this weird issue is happening or where do I need to change in the pipelines?
