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: Derek Buitenhuis <derek.buitenhuis@gmail.com> |

FFmpeg README
FFmpeg is a collection of libraries and tools to process multimedia content such as audio, video, subtitles and related metadata.
Libraries
libavcodec
provides implementation of a wider range of codecs.libavformat
implements streaming protocols, container formats and basic I/O access.libavutil
includes hashers, decompressors and miscellaneous utility functions.libavfilter
provides a mean to alter decoded Audio and Video through chain of filters.libavdevice
provides an abstraction to access capture and playback devices.libswresample
implements audio mixing and resampling routines.libswscale
implements color conversion and scaling routines.
Tools
- ffmpeg is a command line toolbox to manipulate, convert and stream multimedia content.
- ffplay is a minimalistic multimedia player.
- ffprobe is a simple analysis tool to inspect multimedia content.
- ffserver is a multimedia streaming server for live broadcasts.
- Additional small tools such as
aviocat
,ismindex
andqt-faststart
.
