We want to bring YUV422 video into the AM62A through the CSI-2 port. In this case the TRM states the following:
So, normally the VISS would convert non-YUV data into YUV420 into a YUV type format for the rest of the system, but it cannot ingest YUV data itself. Our data will come in as YUV422 and be written directly to memory as YUV422.
However, the TI FAQ page about encoder formats: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1222753/faq-am62a7-video-encode-decode-formats-and-use-cases, lists the following encoder compatible video formats, which does not include YUV422:
Input formats that Encoders support are:
- V4L2_PIX_FMT_YUV420
- V4L2_PIX_FMT_NV12
- V4L2_PIX_FMT_NV21
- V4L2_PIX_FMT_YUV420M
- V4L2_PIX_FMT_NV12M
- V4L2_PIX_FMT_NV21M
If the VISS cannot ingest YUV data, then that includes our YUV422 data and we can’t convert it from YUV422, to YUV420. Without converting it to YUV420, the encoders can’t accept it.
Maybe I’m missing something here, but it seems that there isn’t a path to input YUV422 data in and encode it? Please tell me I’m wrong.
