+
+Decoder Features
+----------------
+- Constrained Baseline Profile up to Level 5.2 (Max frame size is 36864 macro-blocks)
+- Arbitrary resolution, not constrained to multiples of 16x16
+- Single thread for all slices
+- Long Term Reference (LTR) frames
+- Memory Management Control Operation (MMCO)
+- Reference picture list modification
+- Multiple reference frames when specified in Sequence Parameter Set (SPS)
+- Annex B byte stream input
+- YUV 4:2:0 planar output
+
+OS Support
+----------
+- Windows 64-bit and 32-bit
+- Mac OS X 64-bit and 32-bit
+- Linux 64-bit and 32-bit
+- Android 64-bit and 32-bit
+- iOS 64-bit and 32-bit
+- Windows Phone 32-bit
+
+Processor Support
+-----------------
+- Intel x86 optionally with MMX/SSE (no AVX yet, help is welcome)
+- ARMv7 optionally with NEON, AArch64 optionally with NEON
+- Any architecture using C/C++ fallback functions
+
+Building the Library
+--------------------
+NASM needed to be installed for assembly code: workable version 2.10.06 or above, NASM can downloaded from http://www.nasm.us/.
+For Mac OSX 64-bit NASM needed to be below version 2.11.08 as NASM 2.11.08 will introduce error when using RIP-relative addresses in Mac OSX 64-bit
+
+To build the arm assembly for Windows Phone, gas-preprocessor is required. It can be downloaded from git://git.libav.org/gas-preprocessor.git
+
+For Android Builds
+------------------
+To build for android platform, You need to install android sdk and ndk. You also need to export `**ANDROID_SDK**/tools` to PATH. On Linux, this can be done by
+
+    export PATH=**ANDROID_SDK**/tools:$PATH
+
+The codec and demo can be built by
+
+    make OS=android NDKROOT=**ANDROID_NDK** TARGET=**ANDROID_TARGET**
+
+Valid `**ANDROID_TARGET**` can be found in `**ANDROID_SDK**/platforms`, such as `android-12`.
+You can also set `ARCH`, `NDKLEVEL` according to your device and NDK version.
+`ARCH` specifies the architecture of android device. Currently `arm`, `arm64`, `x86` and `x86_64` are supported, the default is `arm`. (`mips` and `mips64` can also be used, but there's no specific optimization for those architectures.)
+`NDKLEVEL` specifies android api level, the default is 12. Available possibilities can be found in `**ANDROID_NDK**/platforms`, such as `android-21` (strip away the `android-` prefix).
+
+By default these commands build for the `armeabi-v7a` ABI. To build for the other android
+ABIs, add `ARCH=arm64`, `ARCH=x86`, `ARCH=x86_64`, `ARCH=mips` or `ARCH=mips64`.
+To build for the older `armeabi` ABI (which has armv5te as baseline), add `APP_ABI=armeabi` (`ARCH=arm` is implicit).
+To build for 64-bit ABI, such as `arm64`, explicitly set `NDKLEVEL` to 21 or higher.
+
+For iOS Builds
+--------------
+You can build the libraries and demo applications using xcode project files
+located in `codec/build/iOS/dec` and `codec/build/iOS/enc`.
+
+You can also build the libraries (but not the demo applications) using the
+make based build system from the command line. Build with
+
+    make OS=ios ARCH=**ARCH**
+
+Valid values for `**ARCH**` are the normal iOS architecture names such as
+`armv7`, `armv7s`, `arm64`, and `i386` and `x86_64` for the simulator.
+Another settable iOS specific parameter
+is `SDK_MIN`, specifying the minimum deployment target for the built library.
+For other details on building using make on the command line, see
+'For All Platforms' below.
+
+For Linux Builds
+--------------
+
+You can build the libraries (but not the demo applications) using the
+make based build system from the command line. Build with
+
+    make OS=linux ARCH=**ARCH**
+
+ You can set `ARCH` according to your linux device .
+`ARCH` specifies the architecture of the device. Currently `arm`, `arm64`, `x86` and `x86_64` are supported   
+
+ NOTICE:
+ 	If your computer is x86 architecture, for build the libnary which be used on arm/aarch64 machine, you may need to use cross-compiler, for example:
+ 		make OS=linux CC=aarch64-linux-gnu-gcc CXX=aarch64-linux-gnu-g++ ARCH=arm64
+   		 or
+    	make OS=linux CC=arm-linux-gnueabi-gcc CXX=arm-linux-gnueabi-g++ ARCH=arm
+
+
+For Windows Builds
+------------------
+
+Our Windows builds use MinGW which can be downloaded from http://www.mingw.org/
+
+To build with gcc, add the MinGW bin directory (e.g. `/c/MinGW/bin`) to your path and follow the 'For All Platforms' instructions below.
+
+To build with Visual Studio you will need to set up your path to run cl.exe.  The easiest way is to start MSYS from a developer command line session.  Instructions can be found at http://msdn.microsoft.com/en-us/library/ms229859(v=vs.110).aspx.  If you need to do it by hand here is an example from a Windows 64bit install of VS2012:
+
+    export PATH="$PATH:/c/Program Files (x86)/Microsoft Visual Studio 11.0/VC/bin:/c/Program Files (x86)/Microsoft Visual Studio 11.0/Common7/IDE"
+
+You will also need to set your INCLUDE and LIB paths to point to your VS and SDK installs.  Something like this, again from Win64 with VS2012 (note the use of Windows-style paths here).
+
+    export INCLUDE="C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\include;C:\Program Files (x86)\Windows Kits\8.0\Include\um;C:\Program Files (x86)\Windows Kits\8.0\Include\shared"
+    export LIB="C:\Program Files (x86)\Windows Kits\8.0\Lib\Win8\um\x86;C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\lib"
+
+Then add `OS=msvc` to the make line of the 'For All Platforms' instructions.
+
+For Windows Phone Builds
+------------------------
+
+Follow the instructions above for normal Windows builds, but use `OS=msvc-wp`
+instead of `OS=msvc`. You will also need gas-preprocessor (as mentioned below
+"Building the Library").
+
+If building for Windows Phone with MSVC 2013, there's no included bat file that sets the lib paths to the Windows Phone kit, but that can be done with a command like this:
+
+    export LIB="c:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\lib\store\arm;c:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\lib\arm;c:\Program Files (x86)\Windows Phone Kits\8.1\lib\arm"
+
+This is only necessary for building the DLL; the static library can be built without setting this.
+
+Note, only Windows Phone 8.1 or newer is supported, 8.0 is no longer supported.
+
+For All Platforms
+-------------------
+
+Using make
+----------
+
+From the main project directory:
+- `make` for automatically detecting architecture and building accordingly
+- `make ARCH=i386` for x86 32-bit builds
+- `make ARCH=x86_64` for x86 64-bit builds
+- `make V=No` for a silent build (not showing the actual compiler commands)
+- `make DEBUGSYMBOLS=True` for two libraries, one is normal libraries, another one is removed the debugging symbol table entries (those created by the -g option)
+
+The command line programs `h264enc` and `h264dec` will appear in the main project directory.
+
+A shell script to run the command-line apps is in `testbin/CmdLineExample.sh`
+
+Usage information can be found in `testbin/CmdLineReadMe`
+
+Using meson
+-----------
+
+Meson build definitions have been added, and are known to work on Linux
+and Windows, for x86 and x86 64-bit.
+
+See <http://mesonbuild.com/Installing.html> for instructions on how to
+install meson, then:
+
+``` shell
+meson builddir
+ninja -C builddir
+```
+
+Run the tests with:
+
+``` shell
+meson test -C builddir -v
+```
+
+Install with:
+
+``` shell
+ninja -C builddir install
+```
+
+Using the Source
+----------------
+- `codec` - encoder, decoder, console (test app), build (makefile, vcproj)
+- `build` - scripts for Makefile build system
+- `test` - GTest unittest files
+- `testbin` - autobuild scripts, test app config files
+- `res` - yuv and bitstream test files
+
+Known Issues
+------------
+See the issue tracker on https://github.com/cisco/openh264/issues
+- Encoder errors when resolution exceeds 3840x2160
+- Encoder errors when compressed frame size exceeds half uncompressed size
+- Decoder errors when compressed frame size exceeds 1MB
+- Encoder RC requires frame skipping to be enabled to hit the target bitrate,
+  if frame skipping is disabled the target bitrate may be exceeded
+
+License

+  * Step 2:decoder creation
+  * @code
+  *  WelsCreateDecoder(&pSvcDecoder);

+  * @code
+  *  SDecodingParam sDecParam = {0};

+  *        this can be done in a loop until data ends

+  *  //no-delay decoding can be realized by directly calling DecodeFrameNoDelay(), which is the recommended usage.
+  *  //no-delay decoding can also be realized by directly calling DecodeFrame2() again with NULL input, as in the following. In this case, decoder would immediately reconstruct the input data. This can also be used similarly for Parsing only. Consequent decoding error and output indication should also be considered as above.
+  *  iRet = pSvcDecoder->DecodeFrame2(NULL, 0, pData, &sDstBufInfo);
+  *  //judge iRet, sDstBufInfo.iBufferStatus ...

+// and detach when the object goes out of scope. Additional thread checking
