about encoding the YUV data with 420P format using dm355 mpeg4 encoder

All,

 

Can it encode YUV data with YUV420p format to mpeg4 using dm355 mpeg4 encoder? How to set the encoder parameters? Thanks in advance.

 

When I changed the inputChromaFormat as XDM_YUV_420P in DVSDK example venc, I got failure.

 

Best Regards,

Jeff

    Hi Jeff,

    What type of error do you get?  FYI, looking at MPEG 4 encoder user guide (included with DVSDK), it appears XDM_YUV_420P is supported but there is a note of caution with regards to the input buffer format.  How are you getting the 420 Planar data into DDR2?

    Additionally, the MPEG4 Release Notes (also included in DVSDK) suggests that YUV 420 input is not supported, so even though it may work, it is not a supported feature in the codec.
