dm644x h264enc + IH264VENC_StreamFormat

S.C

Hi,

I need help in setting the IH264VENC_StreamFormat field for h264enc on dm6446 platform. The h264enc's user's guide pdf has IH264VENC_StreamFormat listed, but look at the ih264venc.h, there is nowhere to set it. The default stream is IH264_BYTE_STREAM, my 3rd-party middle ware can only work with IH264_NALU_STREAM. I guess this field is codec specific, so please help me with h264enc on dm6446. Thanks!!!!

BTW, I am using h264enc version "H264ENC.version.2.00.004.wizardversion.0.5" on DM6446.

Would assume the IH264VENC_StreamFormat field be set somewhere in IH264VENC_DynamicParams struct. Looking at the definition of IH264VENC_DynamicParams struct, there is no clue where the offset for this field is. So, please help!

H264 encoder version 2.00.004 on DM6446 does not support stream format as dynamic parameter.

Upgraded the h264enc for dm6446 to H264ENC.version.02.02.00.02.wizardversion.0.5.2,with verious upgrades of targetcomponents for the dvsdk (fc, xdais, bios, etc).

1. Does it support StreamFormat as NALU instead of ByteStream?

2. The User's Guide says this version has "User configurable Group of Pictures (GOP) length supported",
could you please tell me how? I searched its header files and did not see anything related....

Thanks a ton!
