Baseline Profile support in DM365 H.264 Encoder?

Tom Hanson
Intellectual 920 points

I'm using dvsdk_2_10_01_18 with H.264 High Profile Encoder v01.00.00, Build ID: 01.00.00.18 (per documentation)

Experimentation shows that this encoder ONLY supports High Profile although the documentation suggests otherwise (i.e. User's Guide, section 4.2.2.1 "profileIdc XDAS_Int32 ... The value must be set to 66(Base line profile), 77(main profile), 100(high profile).  Default value = 100.")

1) Is this correct?

2) Is there a version coming which will support other profiles? If so, when is it expected?

Thanks!

    Hi Tom,

    H.264 encoder in DVSDK 2.10.01.18 supports all profiles. Can you please provide your parameters for H.264 encoder that you are setting for BP? Default parameters are set for High Profile.

    I looked through the encoder documentation and couldn't find any reference to which parameters are compatible/incompatible with which mode.  Where is this documented???

    Here's what I'm currently using (mostly defaults):

    h264Params->videncParams.encodingPreset = 2

    h264Params->videncParams.rateControlPreset = 2

    h264Params->videncParams.maxHeight = 480

    Hi Tom,

    I am working with the team internally to address the settings of base profile in document. I have tested at my end and i can see following parameters are not correct for BP.

    Values of parameters should be as below:

    h264Params->seqScalingFlag = 0

    h264Params->transform8x8FlagIntraFrame = 0

    h264Params->transform8x8FlagInterFrame = 0

    Regards,

    Anshuman

    Hi Tom,

    Please refer to Appendix B of the userguide of H.264 encoder and you can see the parameters that return error for different profiles.

    To which version of the UG are you referring?  I have  H.264 High Profile Encoder on DM365 User’s Guide
    SPRUEU9, March 2009. 

    That version doesn't have an Appendix B

    hi Anshuman ,

    I have been looking for the Appendix B of the userguide of H.264 encoder for a long time . but I failed. so I was hoping you could send it to me by email at xiaogang_210@163.com. or send me a link for downloading the userguide of H.264. It will be appreciated if you could do that for me .

    Best regards.
