An error occurs when a Ffmpeg+mediamtx.exe stream is pushed to the network port VLC based on the MIP

[ximenbingmeng]

We are using the Ffmpeg(FFmpeg5.1.2)+mediamtx.exe stream push to the network port solution, in which the USB camera can push the stream to VLC, but the MIPI camera pushes the following error:

The ingest command is as follows:
#MIPI camera
ffmpeg -re -i /dev/video0 -vcodec libx264 -preset:v ultrafast -tune:v zerolatency -rtsp_transport tcp -f rtsp rtsp://192.168.1.12:8554/stream
#USB camera
ffmpeg -re -i /dev/video1 -vcodec libx264 -preset:v ultrafast -tune:v zerolatency -rtsp_transport tcp -f rtsp rtsp://192.168.1.12:8554/stream

The OV5640 camera on the MIPI-CSI interface can be previewed, and the MIPI-CSI interface can be called through the gst-rtsp-server solution to push streams to the network port. Please help to divide the reason for the error, thank you!

Hi

Here is the supported format in csi bridge.

static struct mx6s_fmt formats[] = {
	{
		.name		= "UYVY-16",
		.fourcc		= V4L2_PIX_FMT_UYVY,
		.pixelformat	= V4L2_PIX_FMT_UYVY,
		.mbus_code	= MEDIA_BUS_FMT_UYVY8_2X8,
		.bpp		= 2,
	}, {
		.name		= "YUYV-16",
		.fourcc		= V4L2_PIX_FMT_YUYV,
		.pixelformat	= V4L2_PIX_FMT_YUYV,
		.mbus_code	= MEDIA_BUS_FMT_YUYV8_2X8,
		.bpp		= 2,
	}, {
		.name		= "YUV32 (X-Y-U-V)",
		.fourcc		= V4L2_PIX_FMT_YUV32,
		.pixelformat	= V4L2_PIX_FMT_YUV32,
		.mbus_code	= MEDIA_BUS_FMT_AYUV8_1X32,
		.bpp		= 4,
	}, {
		.name		= "RAWRGB8 (SBGGR8)",
		.fourcc		= V4L2_PIX_FMT_SBGGR8,
		.pixelformat	= V4L2_PIX_FMT_SBGGR8,
		.mbus_code	= MEDIA_BUS_FMT_SBGGR8_1X8,
		.bpp		= 1,
	}
};
