* Revert "hwcontext_vulkan: only use one semaphore per image"Lynne2020-05-113-89/+91
| | | | | | | | | This reverts commit 97b526c192add6f252b327245fd9223546867352. It broke the API, and assumed no other APIs used multiple semaphores. This also disallowed certain optimizations to happen. Dealing with APIs that give or expect single semaphores is easier when we use per-image semaphores.

* hwcontext_vulkan: convert to general layout and transfer queue when exportingLynne2020-05-101-1/+19
| | | | | | | The specs note that images should be in the GENERAL layout when exporting for maximum compatibility. CUDA exported images are handled differently, and the queue is the same, so we don't need to do that there.
* hwcontext_vulkan: create all images with concurrent sharing modeLynne2020-05-102-31/+52
| | | | | | | | | As it turns out, we were already assuming and treating all images as if they had concurrent access mode. This just changes the flag to CONCURRENT, which has less restrictions than EXCLUSIVE, and fixed validation messages on machines with multiple queues. The validation layer didn't pick this up because the machine I was testing on had only a single queue.

* hwcontext_vulkan: remove unused internal REQUIRED extension flagLynne2020-05-101-16/+4
| | | | | This is a leftover from an old version which used the 1.0 Vulkan API with the maintenance extensions being required.
* hwcontext_vulkan: expose enabled device and instance extensionsLynne2020-05-104-11/+56
| | | | | | | This solves a huge oversight - it lets users reliably use their own AVVulkanDeviceContext. Otherwise, the extensions supplied and enabled are not discoverable by anything outside of hwcontext_vulkan. Also clarifies that any user-supplied VkInstance must be at least 1.1.
* hwcontext_vulkan: let users enable device and instance extensions using optionsLynne2020-05-102-7/+81
| | | | | | Also documents all options supported by the hwdevice. This lets users enable all extensions they need without writing their own instance initialization code.

* avcodec/v4l2_context: Finish draining if V4L2_BUF_FLAG_LAST is setAndriy Gelman2020-05-091-0/+4
| | | | | | | | | | | | | | | | | | V4L2 api can indicate that flushing of the capture buffers is completed by setting the V4L2_BUF_FLAG_LAST flag. Use guards because the flag was only defined in Linux v4.2. Reference: linux/Documentation/media/uapi/v4l/dev-decoder.rst "The client must continue to handle both queues independently, similarly to normal decode operation. This includes: ... - queuing and dequeuing CAPTURE buffers, until a buffer marked with the V4L2_BUF_FLAG_LAST flag is dequeued" Reviewed-by: Ming Qian <ming.qian@nxp.com> Signed-off-by: Andriy Gelman <andriy.gelman@gmail.com>
* avcodec/v4l2_context: Drop empty packet while drainingAndriy Gelman2020-05-091-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | v4l2_m2m devices may send an empty packet/frame while draining to indicate that all capture buffers have been flushed. Currently, the empty packet/frame is not handled correctly: When encoding, the empty packet is forwarded to the muxer, usually creating warnings. When decoding, a reference to the memory is created anyway. Since in the past this memory contained a decoded frame, it results in an extra frame being decoded. This commit discards the empty packet/frame. References: linux/Documentation/media/uapi/v4l/dev-decoder.rst: "The last buffer may be empty (with :c:type:`v4l2_buffer` bytesused = 0) and in that case it must be ignored by the client, as it does not contain a decoded frame." linux/Documentation/media/uapi/media/v4l/vidioc-encoder-cmd.rst: "...This buffer may be empty, indicated by the driver setting the ``bytesused`` field to 0."
