imx8qxp how to use vpu encoder,vpu decoder is ok

[zhou1211]

When not using VPU, many videos may not play smoothly, just like pictures;I have enabled VPU, the vpu decoder is normal, but the vpu encoder has failed; This leads to abnormal recording function. Is there any solution to this problem.

dmesg log for encoder:

[VPU Encoder] vpu vpu_enc_probe :6002
vpu-b0-encoder 2d000000.vpu_encoder: mbox_request_channel_byname() could not locate channel named "enc1_tx0"

Hi @zhou1211,

I hope you are doing well.

The device tree seems ok. Please check there isn't any typo error. 

Please share the whole log file to further debug the issue.

One can refer below document for more information related to the same.

Added HAL configuration and adjusted the number of devices, the encoding function is normal.

hal:

};

During video playback, it was found that two so files were missing, resulting in the inability to play rmvb and wmv videos. Can you provide the corresponding files. The log is attached and the main errors are as follows:

Hi @zhou1211,

I hope you are doing well

The packages you listed are restricted codec packages and are not generally available.

Please take a look at Table 1. Enhanced codecs and Section 6 License-Restricted Codecs from the i.MX Android ™ Extended Codec Release Notes of your Android version for more information.
