Function Documentation

◆ video_stream_start()

int video_stream_start	(	const struct device *	dev,
		enum video_buf_type	type )

#include <video.h>

Start the video device function.

video_stream_start is called to enter ‘streaming’ state (capture, output...). The driver may receive buffers with video_enqueue() before video_stream_start is called. If driver/device needs a minimum number of buffers before being able to start streaming, then driver set the min_vbuf_count to the related endpoint capabilities.

Parameters

dev	Pointer to the device structure.
type	The type of the buffers stream to start.

Return values

0	Successful.
-EINVAL	Parameters are invalid.
-EIO	General input / output error.

int video_stream_stop	(	const struct device *	dev,
		enum video_buf_type	type )
