Hi everyone:<div>I need some help to improve my project</div><div>I used to type "gst-launch -v filesrc location = 'xxxx.mp4' ! typefind ! qtdemux name=demux demux. ! queue2 ! ffdec_h264 ! xvimagesink demux. ! queue2 ! ffdec_aac ! autoaudiosink" to play a mp4 file, which composed by h-264 and AAC. it worked fine</div>
<div>But in my coding, it will freeze at the first frame, I have tried to set property of queue2 "max-size-time", some of mp4 sources will get better.</div><div>I also used "current-size-time" to get some info about the queue2, but I don't know the relationship between them</div>
<div>anybody who can give some hints about them?</div><div>Or I have on idea about my coding, Why it will not work but I will work in command line ?</div><div>The structure of pipeline are totally same</div><div><br></div>
