DM36x H.264 Decoder - Generic Questions

Martin1980

Hi All,

I would like to know what the difference is between Vdec1 and Vdec2?

I'd also like to know how to change the profile of decoder? If this is possible? (since the parameter doesn't appear to be present in the extended params struct).

I'm using a DM368, and DVSDK 4_02_00_06

Regards,

Martin

Vdec1 and Vdec2 are interface versions of XDM Interface XDM1.1 and XDM1.2. XDM1.2 or Vdec2 is next version of XDM1.1 with more interface parameters.(You can google for more info)

Profile information will be present in input bitstream, so decoder doesn't need this information from application. And something like LevelIdc which decides DPB size, needs to set by application.

Thanks,
