Various vicodec improvements that make it more useful and easier to re-use in userspace applications like v4l2-ctl and qvidcap. - add support for quantization parameters - support many more pixel formats - code simplifications - rename source and use proper prefixes for the codec: this makes it independent from the vicodec driver and easier to reuse in userspace (similar to what we do for the v4l2-tpg code). - split off the v4l2 'frontend' code for the FWHT codec into its own source for easier re-use elsewhere (i.e. v4l2-ctl/qvidcap). - fix out-of-range values when decoding. I made a v4l-utils branch that uses the FWHT codec to compress video when streaming over the network: https://git.linuxtv.org/hverkuil/v4l-utils.git/log/?h=qvidcap Regards, Hans The following changes since commit 3799eca51c5be3cd76047a582ac52087373b54b3: media: camss: add missing includes (2018-08-29 14:02:06 -0400) are available in the Git repository at: git://linuxtv.org/hverkuil/media_tree.git vicodec for you to fetch changes up to a12ff4f22c26492ee38dc27fe04a2f90aeb98d8b: vicodec: fix out-of-range values when decoding (2018-08-30 10:35:18 +0200) ---------------------------------------------------------------- Hans Verkuil (8): vicodec: add QP controls vicodec: add support for more pixel formats vicodec: simplify flags handling vicodec: simplify blocktype checking vicodec: improve handling of uncompressable planes vicodec: rename and use proper fwht prefix for codec vicodec: split off v4l2 specific parts for the codec vicodec: fix out-of-range values when decoding Documentation/media/uapi/v4l/pixfmt-compressed.rst | 2 +- drivers/media/platform/vicodec/Makefile | 2 +- drivers/media/platform/vicodec/{vicodec-codec.c => codec-fwht.c} | 158 +++++++++---- drivers/media/platform/vicodec/{vicodec-codec.h => codec-fwht.h} | 80 +++---- drivers/media/platform/vicodec/codec-v4l2-fwht.c | 325 +++++++++++++++++++++++++ drivers/media/platform/vicodec/codec-v4l2-fwht.h | 50 ++++ drivers/media/platform/vicodec/vicodec-core.c | 483 ++++++++++++++++---------------------- 7 files changed, 731 insertions(+), 369 deletions(-) rename drivers/media/platform/vicodec/{vicodec-codec.c => codec-fwht.c} (84%) rename drivers/media/platform/vicodec/{vicodec-codec.h => codec-fwht.h} (64%) create mode 100644 drivers/media/platform/vicodec/codec-v4l2-fwht.c create mode 100644 drivers/media/platform/vicodec/codec-v4l2-fwht.h
