libyuv: make shared object - Adjust port to Genode expected layout - Make shared library - Adjust dependent infrastructure to change issue #4196 2021-05-25 09:01:55 +00:00			`SHARED_LIB = yes`

libs: use `select_from_ports` in eager assignments If `select_from_ports` is evaluated lazily, we might miss a port during the dependency check. A way to prevent this is to use the `:=` operator. Fixes genodelabs/genode#4618 2022-09-23 13:05:17 +00:00			`YUV_PORT := $(call select_from_ports,libyuv)`
			`YUV_DIR = $(YUV_PORT)/src/lib/libyuv`
libports: add libyuv support Issue #4078 2021-04-22 12:45:12 +00:00
libyuv: add support to overwrite default allocator Internally libyuv uses malloc & free for short time dynamic memory allocation during image transformation. The converted images are such large, that the Libc allocator will create and destroy new Genode dataspace per image. In time sensitive code paths, the overhead can be noticeable by the caller of the image transformation. The patch adds the option to register callbacks in the libyuv library to implement the image allocation by users of the library. They may implement caching strategies to avoid the overhead, e.g. as seen with qemu-usb and the webcam model. 2023-09-15 11:44:26 +00:00			`LIB_DIR = $(REP_DIR)/src/lib/libyuv`
