Harish Mahendrakar 052d028555 Fix heap-buffer-overflow in HBD padding due to bit depth change. 
Trigger IVD_RES_CHANGED when bit depth or chroma format changes in SPS,
forcing reallocation of picture buffers.

To prevent corrupting the codec state on invalid SPS parses, the updates to
global codec parameters (like i4_pixel_size_y and i4_bit_depth_luma) are
deferred to the end of ihevcd_parse_sps, after all validation checks have
passed. The resolution change check now compares the old active values in
ps_codec against the newly parsed values in the temporary ps_sps structure.

LIBHEVC

Getting Started Document

LibHEVC build steps

Supports:

  • aarch32/aarch64 on Linux.
  • aarch32/aarch64 on Android.
  • x86_32/x86_64 on Linux.
  • aarch64 on Mac.
  • x86_64 on Mac.

Native Builds

Use the following commands for building on the target machine

$ cd external/libhevc
$ mkdir build
$ cd build
$ cmake ..
$ make

Cross-compiler based builds

Building for x86_32 on a x86_64 Linux machine

$ cd external/libhevc
$ mkdir build
$ cd build
$ CFLAGS="-m32" CXXFLAGS="-m32" LDFLAGS="-m32" cmake ..
$ make

Building for aarch32/aarch64

Update 'CMAKE_C_COMPILER', 'CMAKE_CXX_COMPILER', 'CMAKE_C_COMPILER_AR', and 'CMAKE_CXX_COMPILER_AR' in CMAKE_TOOLCHAIN_FILE passed below

$ cd external/libhevc
$ mkdir build
$ cd build

For aarch64

$ cmake .. -DCMAKE_TOOLCHAIN_FILE=../cmake/toolchains/aarch64_toolchain.cmake
$ make

For aarch32

$ cmake .. -DCMAKE_TOOLCHAIN_FILE=../cmake/toolchains/aarch32_toolchain.cmake
$ make

Building for android

NOTE: This assumes that you are building on a machine that has Android NDK.

$ cd external/libhevc
$ mkdir build
$ cd build

Armv7 (32-bit)

cmake -DCMAKE_TOOLCHAIN_FILE=../cmake/toolchains/android_toolchain.cmake\
    -DHEVC_ANDROID_NDK_PATH=/opt/android-ndk-r26d/\
    -DANDROID_ABI=armeabi-v7a\
    -DANDROID_PLATFORM=android-23 ../
make

Armv8 (64-bit)

cmake -DCMAKE_TOOLCHAIN_FILE=../cmake/toolchains/android_toolchain.cmake\
    -DHEVC_ANDROID_NDK_PATH=/opt/android-ndk-r26d/\
    -DANDROID_ABI=arm64-v8a\
    -DANDROID_PLATFORM=android-23 ../
