Codec FAQ

1. Where to download the latest DM36x codec?

3. "Why there is different structure for SAD output by DM365 h264 encoder? Why the old motion detection algrithm gets wrong behavor with latest h264 encoder?"

There is a bug in SAD structure of before version 01.10.00.08. You can find below in release note of h264 v01.10.00.08.
Fixed In This Release Defect ID Description None Fixed the output format of motion vector and sad data exported to application as per user guide explanation.
So you need to follow the structure as the h264 user guide mentioned as below if you are using the h264 enc v01.10.00.08 or later.

MV SAD information is in the following format:

Word0: MVy[bit 31-16]:MVx[bit 15-0]

Word1: SAD [bit 31-0]

4.How to know the codec version?

Go to the codec folder and check the codec datasheet at \packages\ti\sdo\codecs\CODEC NAME\docs\. CODEC NAME can be h264enc, etc.
