Yes, we used the TI provided codecs. We needed to give the capture/display drivers a workover and some ALSA mods, but the codec engine seemed to be fine. A complete build of everything against the new kernel was in order.
We are using MPEG-4 encode/decode and have not tried the JPEG codec. Also, there was some work done to CMEM to support memory mapping. Also, the RSZCOPY needed some changes. Now that I recall, the DMA enable/disable masks for the board needed to be changed so that the kernel did not hand out DMAs that are in use by the codecs.
