DM8168 H264 and MPEG2 Codecs

_Ralph_

Regarding the H264 and MPEG2 codecs for the DM8168:

1) Where can I obtain datasheets for these codecs? There is no information at all in the "omx" directory of EZSDK 5.02.01.59 that I am using at present.

2) What resources do these codecs use?

3) How can I configure the resources that are used?

4) Is all control for these codecs done by the Media Controller?

5) Is the DSP used at all by these codecs?

Thanks,
Ralph

Codecs use HDVICP2, TILED Memory and RAW Memory as resources.

_Ralph_ said:

Through RMAN config one can configure all the resources required by codec.

Answer is Yes.

Answer is no. All the video processing (Encoding/Decoding) is carried out by HDVICP2.

Hi, I only find the decoder datasheet in that page.

Where can I find the encoder datasheet and user guide?

Here is one more question

Does this codec use dma?

I really care about this. In the h264_encoder_dm6467_pdf, there are some discription of dma useage.

I find that dsp&arm can't do its works when hdvicp start h264 encode on dm6467.

I hope that dm8168 will not have the same problem.

Thanks.

Hi,

The http://software-dl.ti.com/dsps/dsps_public_sw/codecs/HDVICP2/index_FDS.html does not mention any encoder.

Is there any update regarding information about the H.264 encoder ?

Thanks,

Sandro

TI provides H264 codec and MPEG-2 decoder for DM8168. Ittiam Systems has developed MPEG-2 encoder for DM8168 for customers who are looking for the legacy MPEG-2 encoder. Contact us if you need more information regarding to MPEG-2 encoder.

In DM8168, the data transfers of video data for encode and decode on HDVICP2 is entirely handled by a standalone DMA module called vDMA inside HDVICP2.

Hence Video DMA is fully encapsulated inside HDVICP2 in DM8168.
