RASPBERRYPI ONLY: Handle mandatory stream flags
Look for the RAW mandatory stream flag in the pipeline handler config
file. If this flag is set, it guarantees that the application will
provide buffers for Unicam Image, so override the minUnicamBuffers and
minTotalUnicamBuffers config parameters in the following way:
- If startup drop frames are required, allocate at least 1 internal buffer.
- If no startup drop frames are required, do not allocate any internal buffers.
Look for the Output 0 mandatory stream flag in in the pipeline handler
config file. If this flag is set, it guarantees that the application
will provide buffers for the ISP, do not allocate any internal buffers
for the device.
Add a new rpi_apps.yaml pipeline handler config file that enables both
these flags. To use the file, set the following env variable for a
custom build:
export LIBCAMERA_RPI_CONFIG_FILE=/usr/local/share/libcamera/pipeline/rpi/vc4/rpi_apps.yaml
or for a packaged install:
export LIBCAMERA_RPI_CONFIG_FILE=/usr/share/libcamera/pipeline/rpi/vc4/rpi_apps.yaml
