Hi，
When debugging app_multi_cam_codec, we encountered the problem that the video could not be decoded. The error message is as follows:
To this end, I made the following three attempts: 1. Only enable encoding and disable decoding function, select YUV camera, can successfully encode and save mp4 files; 2. 2. If the encoding and decoding function is enabled at the same time, the mp4 file cannot be decoded; 3, only enable the decoding function, also cannot decode mp4 files.
Please help me solve this problem, thank you! The log is attached.Please check.
Capture->Encode Selection Yes(1)/No(0)
0
Decode->Display Selection Yes(1)/No(0)
1
Max number of cameras supported by sensor MAX_RAW12_AR0147 = 4
Please enter number of channels to be enabled
