The Video Engine (VE) embedded in the Aspeed AST2400 and AST2500 SOCs can capture and compress video data from digital or analog sources. With the Aspeed chip acting a service processor, the Video Engine can capture the host processor graphics output. Add a V4L2 driver to capture video data and compress it to JPEG images, making the data available through a standard read interface.

It seems you are not using videobuf2. I think it should simplify the read I/O part and at the same time expose the other capture methods. There are plenty of examples to follow. Regards, Eze
