media: visl: Fix ERANGE error when setting enum controls

2025-02-25T10:11:06+00:00

The visl driver supports both frame and slice mode, with and without a start-code. But, the range and default for these enum controls was not set, which currently limits the decoder to enums with a value of 0. Fix this by setting the decoder mode and start code controls for both the H.264 and HEVC codecs.

media: test-drivers: drop vb2_ops_wait_prepare/finish

2024-10-28T08:19:49+00:00

Since commit 88785982a19d ("media: vb2: use lock if wait_prepare/finish are NULL") it is no longer needed to set the wait_prepare/finish vb2_ops callbacks as long as the lock field in vb2_queue is set. Since the vb2_ops_wait_prepare/finish callbacks already rely on that field, we can safely drop these callbacks. This simplifies the code and this is a step towards the goal of deleting these callbacks. Signed-off-by: Hans Verkuil Reviewed-by: Shuah Khan

media: test-drivers: Use V4L2_FMTDESC_FLAG_ENUM_ALL flag

2024-10-12T17:56:16+00:00

Since the V4L2_FMTDESC_FLAG_ENUM_ALL flag mostly targets stateless decoder pixel-format enumeration, update visl test driver to use it. When V4L2_FMTDESC_FLAG_ENUM_ALL flag is set let the driver returns one more pixel format. Signed-off-by: Benjamin Gaignard Signed-off-by: Hans Verkuil

media: Switch back to struct platform_driver::remove()

2024-10-12T14:28:25+00:00

After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/media to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer.

media: visl: Add codec specific variability on output frames

2024-02-16T10:46:33+00:00

When running tests with different input data, the stable output frames could be too similar and hide possible issues. This commit adds variation by using some codec specific parameters. Only HEVC and H.264 support this. Reviewed-by: Daniel Almeida Signed-off-by: Detlev Casanova Signed-off-by: Hans Verkuil [hverkuil: add media: prefix to Subject]

media: visl: Add a tpg_verbose parameter

The text written on the output frames stable for a given input. Remove the unstable elements like pointers, buffer indexes or queues status so that frames are always identical and can be compared against a reference in automatic tests. As the unstable information can be relevant when debugging the API, add a tpg_verbose parameter to show them.

The (TRY_)DECODER_CMD ioctls are used to support flushing when holding capture buffers is supported. This is the case of this driver but the ioctls were never hooked to the ioctl ops.
