Linux/AM5728: General video support questions

Part Number: AM5728

Tool/software: Linux

Good day.

We want to use one of Sitara processors in our designs for video processing. We used DaVinci before. Help us to clarify some points.

1. What's minimal DDR volume for IVAHD subsystem video buffers? We need H264 encoding.

2. Which firmware is used in gstreamer for ducatih264enc plugin? How is it being loaded? For DaVinci we used firmware loader.

I don't have kit at the moment. Only downloaded SDK and found xem4 files. I've just started. Point me to relevant topics if questions is answered.

Thanks in advance.

    Please refer to the datasheet document of H.264 encoder for memory need. Note that the table in the docuement doesn't include the input/out buffer memory requirement (owned by application).

    dra7-ipu2-fw.xem4.ipummm-fw firmware is used for all the codecs running on IVA-HD, controlled by M4. The firmware can be found inside filesytem in /lib/firmware. remote-proc kernel component loads the M4 firmware at kernel booting time. grep for "remoteproc" in the kernel dmesg log to see the boot logs associated with firmware loading.
