avcodec/libx265: use x265 Multi-library Interface to query the API
ffmpeg can now use the x265 multi-library interface to make a runtime selection between a number of libx265 libraries (perhaps 8bpp and 16bpp). ffmpeg will link to one build of libx265 (statically or dynamically) and this linked version of libx265 will support one bit-depth (8 or 10 bits). At runtime, ffmpeg now has the option to request the encoder to use a different bit depth(8 or 10). If the requested bitdepth is zero, or if it matches the bitdepth of the system default libx265 (the currently linked library), then this library will be used for encode. If ffmpeg requests a different bit-depth, the linked libx265 will attempt to dynamically bind a shared library with the requested bit-depth from the install location (default or user-specified). new x265 API: const x265_api* api = x265_api_get(int bitDepth); x265_api - holds the libx265 public API functions bitDepth - requested API for 8bpp or 16bpp note: Use 0 to indicate native bit depth of the linked libx265 and x265_api_get(0) is guaranteed to return a non-null pointer Signed-off-by:Gopu Govindaswamy <gopu@multicorewareinc.com> Signed-off-by:
