Jitter and pause in video playing using gstreamer ...
Locked
 
|
Hi all , I am using gstreamer to stream video from a file source in iMX27 freescale app processor. I have used the gst-launch command and i get the video output. But the video has jitter and sometimes pause for some time. I dont understand the problem since there is no error message. Here is the code for the output... ################################################################################################### mx27# Setting pipeline to PAUSED ... Pipeline is PREROLLING ... /pipeline0/mfwgstvpu_dec0.sink: caps = video/mpeg, mpegversion=(int)4, systemstream=(int)0, height=(int)240, width=(int)320, framerate=(fraction)24999/1000 /pipeline0/mfwgstvpu_dec0.sink: caps = video/mpeg, mpegversion=(int)4, systemstream=(int)0, height=(int)240, width=(int)320, framerate=(fraction)24999/1000 WARNING: from element /pipeline0/demux: pads are not negotiated!

Hi, gstreamer-devel:
1. Add a probe in front of your sink element and print every buffer's timestamp. If the timestamp is discontinuous, consider all the elements in your pipeline which modified the timestamp.
2. If the timestamp of buffer is OK, watch the CPU load. It is possible that your processor cannot decode quickly.
