Video Encoding and Decoding on imx8m

[fengyang]

      Hello:

      I want to know if there are any examples of vpu mxc_vpu_test similar to imx6 on imx8m.

      I want to implement the same functions in mxc_vpu_test directory on imx8m, including encoding and decoding H264 stream and UDP transmission of code stream, but I am not sure which library I should use to implement it, and I can't find the relevant documentation.

      If you have any information on this, can you share it with me?

      Thank You

Hello y.f.

You can find the information related to VPU in Linux reference manual of your BSP documentation There is only a user-space programming interface for the VPU module. A user in the application layer cannot access the kernel driver interface directly. The VPU library accesses the kernel driver interface for users. if you want to tranport UDP In Linux OS, run 1588 stack binary with the following commands.Linuxptp:
Transport on UDP IPV4 with E2E delay mechanism: ptp4l -A -4 -H -m -i eth0
Transport on UDP IPV4 with P2P delay mechanism: ptp4l -P -A -4 -H -m -i eth0

Transport on UDP IPV6 with E2E delay mechanism: ptp4l -A -6 -H -m -i eth0
