On the development board, I found the source code mxc_v4l2_vpu_test, which reads the v4l2 camera image and encodes it and saves it to a local file.I adjusted the code, followed by the imx6 codec routine in mxc_vpu_enc.c to add UDP transmission implementation, and finally using imx8qm as the encoding end, imx6 as the decoding end, Data transmission through udp, but currently encountered some problems: the decoding terminal received the image has a delay of about 3 seconds, i found that imx8qm will have a storage frame operation before encoding, The vpu start encode when the cache area after four frame data , but I think 4 frame data is also not been such a long delay.
If you have ideas or related information about encoding on the IMX8qm,please share to me!
Thank you!
