DM814X: More than 4 Audio channel support with DVR-RDK

Other Parts Discussed in Thread: TVP5158

Hi,

We are using DVR-RDK 03.00.01.03 with DM814X EVM. We want to support 8 channel Audio capture using two TVP5158, and encode them in AAC-LC.

In RDK, McFW defines a macro "ACAP_CHANNELS_MAX" which is 4, for DM814X, so more than 4 Audio channels are not working.

What needs to be done to add more than 4 Audio channel capture, encode support in RDK?

Thanks & Regards,

Dharati Shah

    DVR RDK 03.00.01.03 was not validated for audio channels > 4 for DM814x. You might have to do several changes referring to wherever ACAP_CHANNELS_MAX is used in these files -

    1. dvr_rdk\mcfw\src_linux\mcfw_api\ti_audio.c

    2. dvr_rdk\mcfw\src_linux\links\audio\audio_capture.c
