Wheather Dm81xx can decode the H264 video with 25fps(not 30fps) ?

Hello all:

  Now I use ezsdk_5_04_00_11(or the older version) on DM8148,When I use the gstreamer  command to play a  H264 video  with 25fps(not 30fps) ,I found the rate of playing the video was faster than the actual rate,although I set the framerate of the caps to 25fps,Accoroding to the file gstomx_h264dec.c，I found the omx_h264dec plugin maybe only support the 30fps,am I right?

  So,What I can do if I want to play the 25fps H264 video?Thanks.

             Regards .zhihcao

    Dear  zhihcao,

    We have the same issue. I played the H264 video with 30fps is very smoothly, When we pleyed a H264 video with 25fps,the  video shows stumble.

    I have know the OMX_264DEC not support the 25fps interlace decoder very well.

    We need TI engineer give some support, how the resolve this issue.....

    Hello nuoman:

      In my opinion, The work adding 25fps on omx_h264dec for TI engineer is not very difficult or complex,I think they won't change lots of  code for adding 25fps.But for us,because we have not the initial source code for H264DEC  algorithm(We only have the bin code of firmware ),So we have no methord to add the 25fps for H264dec.

    Dear zhichao:

    I agree with you,.

    If the ti engineer provide the H264DEC code to us,  We can solve this issue by myself.
