libde265 is an open source implementation of the h.265 video codec. It is written from scratch in plain C for simplicity and efficiency. Its simple API makes it easy to integrate it into other software.
libde265 decodes all common types of HEVC files. A few features currently unused by known encoders are missing (long-term MC, weighted prediction, PCM), but will be added once conformant bit-streams are available. Encoding is planned to be added afterwards.
libde265 supports WPP-based multithreading and includes SSE optimizations.
The library comes with two example programs:
-
dec265, a simple player for raw h.265 bitstreams. It serves nicely as an example program how to use libde265.
-
sherlock265, a Qt-based video player with the additional capability to overlay some graphical representations of the h.265 bitstream (like CU-trees, intra-prediction modes).
Example bitstreams can be found, e.g., at this site: ftp://ftp.kw.bbc.co.uk/hevc/hm-10.1-anchors/bitstreams/ra_main/
If you got libde265 from the git repository, you will first need to run
the included autogen.sh script to generate the configure script.
libde265 has no dependencies on other libraries, but both example programs require that you install the libvideogfx library, which you can get from http://www.dirk-farin.net/software/libvideogfx/index.html or http://github.com/farindk/libvideogfx
You can disable building of the example programs by running ./configure with
--disable-dec265 Do not dec265 decoder program. --disable-sherlock265 Do not build sherlock265 visual inspection program.
Additional logging information can be turned on and off using these ./configure flags:
--enable-log-error turn on logging at error level (default=yes) --enable-log-info turn on logging at info level (default=no) --enable-log-trace turn on logging at trace level (default=no)
