Wim Taymans	8175c8276d	pipewire-v4l2: more improvements ... Add support for more formats. Connect in the reqbufs ioctl so that we can negotiate the right amount of buffers. Keep file and buffer maps so that we can map an address to a file and then the address to a buffer of that file. We can then also check if the buffers were unmapped properly. Implement some more ioctls. Add some more checks.	2021-10-14 10:16:35 +02:00
Wim Taymans	b466fe67dd	pipewire-v4l2: Implement more ioctls ... Collect all video/source nodes and enumerate their formats. We use this to return the supported formats and to check if a format is supported. Use evenfd as the even we return from open. Make the eventfd readable when we have a new buffer ready. Connect a stream when setting a format. Collect buffers. Implement mmap/munmap on the buffer memory. Implement queue and dequeue of buffers. This is enough to make the webcam test work in firefox.	2021-10-14 10:16:35 +02:00
