1a0ad3d688 v4l2-utils: only allocate MemPtr when requested 2021-05-06 10:16:21 +02:00

941620b733 v4l2: don't expose the internal fd 
When allocating memory, just export the mmaped memory and mark the
memory as MemPtr, not MemFd. Set the fd to -1.

Otherwise we might send this fd to the client, making the complete
device accessible to the client.

9c8a578e21 v4l2: don't select DmaBuf when the type mask is invalid 
an invalid data type mask means that the caller did not explicitly
allowed DmaBuf so fall back to memptr or memfd.

223f20709d meson: replace join_paths(a, b) with a / b 
More readable and from the meson reference manual:
(since 0.49.0) Using the/ operator on strings is equivalent to calling join_paths.

2b44f42845 pass the complete buffer size to snprintf

af092a9a7e v4l2: respect allowed data types 
Check if we can do DmaBuf as the data type before we attempt this.
Otherwise we don't get any data in clients that can't deal with
DmaBuf.

ed1ee3f164 v4l2: detect driver reusing buffers 
Some drivers seem to only use 2 buffers when asked for 16 buffers. We
can see this because the buffer is already queued. In this case, just
use the 2 buffers.

9f1d84e37c v4l2: in alloc buffer, don't mmap, just pass the fd 
If we can't use EXPBUF, just put the fd and mapoffset in the buffer
memory. This way we can pass the fd to the client and let it mmap .

a9b191971c v4l2: fix buffer recycle

When we captured a frame, put it in the queue. Then dequeue it
into the io area after recycling buffers.

f391353c7f Make interface types a string 
This is more in line with wayland and it allows us to create new
interfaces in modules without having to add anything to the type
enum. It also removes some lookups to map type_id to readable
name in debug.

the port.id/node.id etc to make relations to other objects.
