encoder: hevc encoder expects allocation returns zeroed memory

earlier, hevc encoder memory allocation wrappers were not clearing the memory.it requires explicit calling of memset functions wherever required for memory management.

this has been resolved since the memory reset happens with in the function call and returns the zeroed memory whenever it is called and does memory management efficiently.

LIBHEVC

Getting Started Document

LibHEVC build steps

Supports:

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

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
