AM5728: about VPE and gstreamer for AM5728

Hi Kouji,

1) Are there any restrictions on the images that can be processed by the Video Processing Engine (VPE), such as limiting the data to be input from the Video Input Port (VIP)?
For example, is it possible to convert an image from USB through a CPU and then process it with VPE?

Yes, it is possible to do a memory to memory operation, please refer to the user guide and examples for VPE from the Softwrae Developers Guide: https://software-dl.ti.com/infotainment/esd/jacinto6/processor-sdk-linux-automotive/6_00_00_03/exports/wiki/DRA7xx%20GLSDK%20Software%20Developers%20Guide%20-%20Texas%20Instruments%20Wiki.pdf, search for VPE.

2) When performing H.264 encoding with gstreamer provided by SDK, can it be used even if the resolution is FHD or higher?
(It seems that 4K @ 15fps encode can be done with IVA-HD, but)

The IVAHD supports 1080p at 30fps encode operation. 

Please refer to this FAQ: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/961127/faq-dra745-how-to-determine-if-ivahd-can-be-used-for-a-certain-resolution-and-also-how-many-instances-can-be-supported-for-that-resolution

Hi, Karthik

We continue to accept questions from our customers.
If you know, please answer.

1) Is it possible to convert UYVY to NV12 using vpe for the video input from the USB camera with v4l2src with gstreamer?

2) I am trying to decode the video input by Motion JPEG from a USB camera with v4l2src with ducatijpegdec, but the video decoded from ducatijpegdec does not come out. Can this decoder be used to decode JPEG?

3) Are there any restrictions such as the number of vertical and horizontal pixels when encoding with ducatih264enc must be a multiple of 16 or 32 pixels, for example?

Best Regards,

Kouji Nishigata
