WebA YUV 420 buffer should contain width*height bytes for Y, followed by (width*height)/4) bytes for U. And another (width*height)/4) bytes for V. Hence, if your YUV byte buffer should contain (width*height*3)/2 bytes in size. Just to see the grey scale pattern as you describe it, you'd need to convert the "Y" bytes into 24-bit RGB like the following: Web18 okt. 2024 · cParams.colorFormat = NvBufferColorFormat_YUV420; In 01_video_encode/video_encode_main.cpp, changes to: ctx.raw_pixfmt = V4L2_PIX_FMT_NV12M; cParams.colorFormat = NvBufferColorFormat_NV12; Both results from the two cases have wrong color space values.
