Advance setting problems about H.264 encoder

Hsu Alex

Hello everyone,

I try to test H.264 encoder capability in DM8168 platform, but there are many parameters cannot work, such as B-frame, RefFrames and Mutli-Slice...etc.

Both SDK version "5_00_00_11" and "5_01_01_80" are tested and the testing results are the same.  The following parameters are fail to set into to H.264 encoder:

1. nBFrames (if the value is greater than 0, the encoder will crash)

2. nRefFrames (encoded result is always "1")

3. eLoopFilterMode (encoded result is always "disable")

4. bFlagErrorConcealment (encoded result is always "disable")

5. eSliceMode = "OMX_VIDEO_SLICEMODE_AVCMBSlice" and nSlicesize > 0  (encoded result is always "singal silce")

Does anyone can give me any advice? Appreciate for any response. Thanks a lot!!

 

BRs,

Alex
