H.264 encoder yet uses DSP?

Hi,

I'm interested to know about the DSP use by TI's H.264 encoder.

For DM6467T a CodecEngine-codec was running on DSP, additionally to the use of the HDVICP.

Now I need to know the concerning details for dm8168.

At least at first view into the H.264 example for DM8168, EZSDK 5.01.01.80, within ezsdk/example-applications/omtb_01_00_00_02, it doesn't look for me as if a CodecEngine-codec yet is in use.

I need the DSP for other purposes, too, and I would like to know if I may it use exclusively of if I have to put my stuff into an own CodecEngine-codec.

My questions concerning dm8168 and dm8148:

  1. Does the H.264 encoder still need the DSP, additionally to HDVICP, and if, will that be changed?
  2. If it makes use of the DSP, is that done directly via DSP-Bios or by use of the CodecEngine framework?
  3. If by CodecEngine framework: where can I find the currently used CodecServer to be enabled to add my own codec?
  4. If DSP used directly via DSP-Bios: will that be changed? Into no use of DSP or use via CodecEngine?

Thanks in advance,
Joern.

    Hello,

    The HDVICP2 video compression engine in these devices is designed so that the full video encode/decode process can be completed without the use of the DSP, freeing it up for other processing tasks.

    Hello Marc,

    thanks for your answer, so I may start to use the DSP exclusively for my other purposes - and will trust in that the TI's H.264 implementation for sure will not make any use of the DSP for these platforms.

    Best regards,
    Joern.
