How to use MPEG4 codec library on L138 or 674x

omap33

Other Parts Discussed in Thread: OMAPL138

Hi,

i have problems to get running a sample applicaion included in : ...\cs1omapl138_1_00_00\packages\ti\sdo\codecs\mpeg4enc\app\

It is dedicated for DM6440, but should be compatible with C64+ cores (like L138). After adaptation of cmd file (see SPRAP73), application can be compiled and runs till PROCESS function of the codec. ividEncfxns->process((IVIDENC1_Handle)handle

But it hangs inside of this function.

My questions:

1. is included library mp4venc_ti.l64P compatible with L138?

2. is there any other example/application note how to use this library on L138?

3. can you propose any other solution, how to implement teh MPEG4 encoder on L138 using only 674x core (w/o ARM usage), because the application will run later on naked 674x DSP.

Thanks in advance

omap33,

I'm not familiar with the contents of that library so it is difficult to say if it is really compatible or not with OMAP-L1x or C674x. If it contains only DSP algorithms, it should be compatible. If it uses any hardware accelerators on DM644x, it will not be compatible.

I would recommended a visit to the Embedded Software -> Multimedia Software Codec Forum to see if they can help you out: http://e2e.ti.com/support/embedded/f/356.aspx

And also TI is not provide MPEG4-Encode/decode Codec examples for CCS on OMAPL138/C6748.
