media: drop CONFIG_MEDIA_CONTROLLER_REQUEST_APIThis config option was added during the development of the Request APIto make it easy to disable it.The Request API is now stable so it is time to drop this option altogether.Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab List of files: /linux-6.15/drivers/media/test-drivers/Kconfig

0c078e31 - media: visl: add virtual stateless decoder driver

Sat, 05 Nov 2022 13:58:42 +0000

media: visl: add virtual stateless decoder driverA virtual stateless device for stateless uAPI development purposes.This tool's objective is to help the development and testing ofuserspace applications that use the V4L2 stateless API to decode media.A userspace implementation can use visl to run a decoding loop even whenno hardware is available or when the kernel uAPI for the codec has notbeen upstreamed yet. This can reveal bugs at an early stage.This driver can also trace the contents of the V4L2 controls submittedto it. It can also dump the contents of the vb2 buffers through adebugfs interface. This is in many ways similar to the tracinginfrastructure available for other popular encode/decode APIs out thereand can help develop a userspace application by using another (working)one as a reference.Note that no actual decoding of video frames is performed by visl. TheV4L2 test pattern generator is used to write various debug informationto the capture buffers instead.Signed-off-by: Daniel Almeida Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab List of files: /linux-6.15/drivers/media/test-drivers/Kconfig

9958d30f - media: Kconfig: cleanup VIDEO_DEV dependencies

Sun, 13 Mar 2022 06:25:46 +0000

media: Kconfig: cleanup VIDEO_DEV dependenciesmedia Kconfig has two entries associated to V4L API:VIDEO_DEV and VIDEO_V4L2.On Kernel 2.6.x, there were two V4L APIs, each one with its own flag.VIDEO_DEV were meant to: 1) enable Video4Linux and make its Kconfig options to appear; 2) it makes the Kernel build the V4L core.while VIDEO_V4L2 where used to distinguish between drivers thatimplement the newer API and drivers that implemented the former one.With time, such meaning changed, specially after the removal ofall V4L version 1 drivers.At the current implementation, VIDEO_DEV only does (1): it enablesthe media options related to V4L, that now has: menu "Video4Linux options" visible if VIDEO_DEV source "drivers/media/v4l2-core/Kconfig" endmenubut it doesn't affect anymore the V4L core drivers.The rationale is that the V4L2 core has a "soft" dependencyat the I2C bus, and now requires to select a number of otherKconfig options: config VIDEO_V4L2 tristate depends on (I2C || I2C=n) && VIDEO_DEV select RATIONAL select VIDEOBUF2_V4L2 if VIDEOBUF2_CORE default (I2C || I2C=n) && VIDEO_DEVIn the past, merging them would be tricky, but it seems that it is nowpossible to merge those symbols, in order to simplify V4L dependencies.Let's keep VIDEO_DEV, as this one is used on some make *defconfigconfigurations.Suggested-by: Laurent Pinchart Reviewed-by: Laurent Pinchart Reviewed-by: Jacopo Mondi Reviewed-by: Neil Armstrong # for meson-vdec & meson-ge2dAcked-by: Andrzej Pietrasiewicz Acked-by: Łukasz Stelmach Signed-off-by: Mauro Carvalho Chehab List of files: /linux-6.15/drivers/media/test-drivers/Kconfig

24fb190e - media: vidtv: implement a tuner driver

Fri, 21 Aug 2020 12:58:45 +0000

media: vidtv: implement a tuner driverThe virtual DVB test driver serves as a reference DVB driver and helpsvalidate the existing APIs in the media subsystem. It can also aiddevelopers working on userspace applications.This dummy tuner should support common TV standards such as DVB-T/T2/S/S2,ISDB-T and ATSC when completed.Signed-off-by: Daniel W. S.
