[gst-devel] MP4 file playback in vlc and QT

[Sriharsha]

Hi all..

I wrote plugin for mp4creator ( utility to mux aac and 264 file in mp4 
file). i m using this pipeline for muxing video only in mp4 file.

gst-launch filesrc 
location=/home/Gurpreet/inputfilesmp4/Sample_Files/TEST3_960x540_video_2.5mbps.264 
! h264parse output-format=0 ! video/x-h264,width=960, height=540, 
framerate=25/1 ! queue ! mymp4mux ! filesink 
location=/home/Gurpreet/outputfilesmp4/TEST-960x540-11.mp4

it is working fine with VLC as well as with QT Player. But when i m 
giving another input of same resolution then  its playing but no video 
is coming.
what may be the problem ? and when i m giving 640x360 input of ( 00.44 
seconds ) then it is plying in vlc ( 00:48 sec.) but black screen is 
coming in QT.
for 640x360 resolution why the length is being increased.

for 176 x 144 input it is working fine with vlc and QT.

m i missing anything ?
what needs to be done more ?
