How to dynamic change mpeg4 resolution on DM365?

Hi,

I use mpeg4 hdvicp encoder  (v02.00.00.08) on dm365.

I try to change mpeg4 resolution at run time but the encoded data are always wrong.

The user's guide says the inputwidth and inputheight can be changed before start of encoding.

Does it mean I need to restart the codec if I want to change the resolution?

If yes, how can I restart the codec using the least time?

And what parameters and buffers should I need to modify for the restart process?

 

Thanks & Best Regards,

Kevin

  • Dear all,

    I think Kevin means how reduce the restart time when av_server is confronted with changing resolution. We have traced avServerMainThr.c to disable the related tasks like ldctsk、vnftsk and fdtsk etc in AVSERVER_tskStart() and AVSERVER_tskStop() that we do not use. But we want to know if  TI can provide a optimal method for av_server that will be good.

    Thanks in advance.

    B.R.
