Aayush Soni bbf593f216 libavcenc: fix null buffer dereferencing 
During encoding, if encoder encounters an error, the library returns the
same. If the application ignores it and feeds further input, library
while processing the new input is facing a null dereference.

1. Added a error check in encode API call before processing input
2. Made entropy bitstream buffer overflow errors non-fatal.

LIBAVC

Getting Started Document

LibAVC 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/libavc
$ mkdir build
$ cd build
$ cmake ..
$ make

Cross-compiler based builds

Building for x86_32 on a x86_64 Linux machine

$ cd external/libavc
$ 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/libavc
$ 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
