H.265 video decoder using libde265 (GStreamer plugin) (original) (raw)

gstreamer-libde265

Deprecated

The libde265 plugin has been integrated in upstream GStreamer:https://gstreamer.freedesktop.org/documentation/de265/index.html

Using code from this repository therefore should no longer be necessary.

Building

If you got gstreamer-libde265 from the git repository, you will first need to run the included autogen.sh script to generate the configurescript.

Compile for gstreamer0.10:

$ ./configure --enable-gstreamer0.10
$ make

Compile for gstreamer1.0:

Dependencies

Various libraries are required to build gstreamer-libde265:

libde265-dev (>= 0.7),
libz-dev
libbz2-dev
libgstreamer0.10-dev (only for gstreamer0.10)
libgstreamer-plugins-base0.10-dev (only for gstreamer0.10)
libgstreamer-plugins-bad0.10-dev (only for gstreamer0.10)
libgstreamer1.0-dev (only for gstreamer1.0)
libgstreamer-plugins-base1.0-dev (only for gstreamer1.0)
libgstreamer-plugins-good1.0-dev (only for gstreamer1.0)
libgstreamer-plugins-bad1.0-dev (only for gstreamer1.0)

Prebuilt packages for old versions of Ubuntu are available athttps://launchpad.net/~strukturag/+archive/libde265

Please note that the PPA is no longer maintained since the plugin is part of upstream GStreamer.

Running

To test, make sure the libde265.so.0 is in your LD_LIBRARY_PATH and execute:

$ gst-launch-0.10 \
    --gst-plugin-path=/path/to/gstreamer-libde265/src/.libs/ \
    playbin uri=file:///path/to/sample-hevc.mkv

You can also playback raw H.265/HEVC bitstreams by switching the decoder to raw-mode and passing the desired framerate:

$ gst-launch-0.10 \
    --gst-plugin-path=/path/to/gstreamer-libde265/src/.libs/ \
    filesrc location=/path/to/sample-bitstream.hevc \
    ! libde265dec mode=raw framerate=25/1 ! xvimagesink

The examples folder contains a sample raw bitstream player which can be used instead of passing the various options to gst-launch (assuming you have all necessary plugins in the GStreamer plugin path):

$ ./playhevc --fps=25 /path/to/sample-bitstream.hevc

Other commandline switches are available from

Performance

Decoder performance was measured using the timehevc tool from the examplesfolder. The tool plays a Matroska movie to the GStreamer fakesink and measures the average framerate.

Resolution	avg. fps	CPU usage
720p	298 fps	36 %
1080p	161 fps	43 %
4K	40 fps	55 %
