Video4Linux2 devices usually support a limited set of

If the size for the device is set to 0x0, the input device will

try to auto-detect the size to use.

Only for the video4linux2 device, if the frame rate is set to 0/0 the
|

input device will use the frame rate value already set in the driver.
|

|

Video4Linux support is deprecated since Linux 2.6.30, and will be
|
||||
dropped in later versions.
|

Some usage examples of the video4linux2 devices with ffmpeg and ffplay:
|

|
||||
Note that if FFmpeg is build with v4l-utils support ("--enable-libv4l2"
|
||||
option), it will always be used.
|
||||
|
||||
Follow some usage examples of the video4linux devices with the ff*
|
||||
tools.
|
||||
@example
|
||||
# Grab and show the input of a video4linux device, frame rate is set
|
||||
# to the default of 25/1.
|
||||
ffplay -s 320x240 -f video4linux /dev/video0
|
||||
# Grab and show the input of a video4linux2 device.
|
||||
ffplay -f video4linux2 -framerate 30 -video_size hd720 /dev/video0
|
||||
|
||||
# Grab and show the input of a video4linux2 device, auto-adjust size.
|
||||
ffplay -f video4linux2 /dev/video0
|
||||
|
||||
# Grab and record the input of a video4linux2 device, auto-adjust size,
|
||||
# frame rate value defaults to 0/0 so it is read from the video4linux2
|
||||
# driver.
|
||||
ffmpeg -f video4linux2 -i /dev/video0 out.mpeg
|
||||
# Grab and record the input of a video4linux2 device, leave the
|
||||
framerate and size as previously set.
