In some cases, we don't want the cv requirement to get an image, for instance interop with other versions of opencv
This enables getting a raw image, and handling conversions from the user side.
LabView only accepts %20 instead of + for parameters, only sends '\n' at the boundaries,
and includes the -- when sending the initial boundary. This solves those parts.
This is not fully enough to fix shuffleboard and others, as the NT format for paths is not the correct path.
This is primarily for use on Linux to get by-id or by-path device names.
This information is now part of UsbCameraInfo.
A new entry point was added to UsbCamera to get that camera's UsbCameraInfo.
The alternate paths are also returned in EnumerateUsbCameras.
This allows save and restore of camera settings. The restore is a bit
smarter than the save.
* Fix mime types in mjpeg server
* wpiutil: WPI_LOG: Make sure level is an unsigned int
This avoids a number of shutdown use-after-free races by controlling the
destruction order. It also is a prerequisite to making the internal
interfaces mockable for unit testing.
By default, sources automatically manage their connection based on whether
any sinks are connected. This change allows the user to keep a connection
open or force it closed regardless of the number of connected sinks.
This allows two streams with different compression levels, and also allows
a stream to receive a different compression level than provided by a JPEG
camera (decompress and recompress).
Some cameras will accept a different resolution as the mode but then provide
JPEG images of a different size. Trust the JPEG image size if available.
This also validates the JPEG image is actually JPEG.
During shared library loading, a different libLLVM can be pulled in, causing
llvm symbols from dependent libraries to resolve to that library instead of
this one. This has been seen in the wild with the Mesa OpenGL implementation
in JavaFX applications (see wpilibsuite/shuffleboard#361).
This is clearly a very breaking change. For some level of backwards
compatibility, a namespace alias from llvm to wpi is performed in the "llvm"
headers. Unfortunately, forward declarations of llvm classes will still break,
but compilers seem to generate clear error messages in those cases
("namespace alias 'llvm' not allowed here, assuming 'wpi'").
This change also moves all the wpiutil headers to a single "wpi" subdirectory
from the previously split "llvm", "support", "tcpsockets", and "udpsockets".
Shim headers will be added for backwards compatibility in a later commit.
