Hi,

 

  If you are analyzing a TS stream, its possible to use TS Reader or other
TS readers such as elecard / stream guru..etc which can extract timestamp
data from TS stream. Its also possible for program stream.

Hi Niko,

   Thanks for your help! After going through the demo code I see what's
going on. So we have to find the syncing solution by ourselves. My config
now is NTSC so its giving 30fps output. However many video files have 25fps,
23.7fps and many other fps so we need to implement a solution to play these
files correctly based on timestamp data in the video/audio streams. Does
anyone know how to get DTS, PTS data from the decoder?

Hi Andrew

 

AV Sync isn't done at all in the demos. Audio and video streams are handled
independently. For displaying the video frames, a function called
'waitForVsynch' does the vertical buffer syncing for the display thread.
You'll find that function in display.c. Regarding the frame rate, what
format did you configure your board to? NTSC (30 fps) or PAL (25 fps)? Can
you please recheck your bootargs (and S3 switch) and verify that you
configured your board to PAL.

 

Cheers,

 

Niko

Hi,

     I was wondering how you guys were doing your Audio Video syncing? I've
try using the decode demo to play some streams I extracted from a video, but
the video plays too fast (@30fps, should be 25fps). Anyone run into this
problem before?
