It can also gather dependencies using pkg-config from the system to build the GStreamer plugins such as flac, for example, which needs libflac to build. gst-build bundles libffi or glib in the subprojects directory. gst-build comes with the essential projects you need to start using GStreamer and build it almost without system dependencies. These subprojects use the meson build system as well. wrap files which are located in the subprojects folder to determine the elements of the project such as gstreamer or gst-plugins-base. Gst-build is mainly a meson.build project.
Indeed gst-build is just a Meson project including GStreamer sub-projects with options to enable/disable selected sub-projects. For its simplicity, speed and flexibility, Meson replaced Autotools, so it is also perfect to use with gst-build. Since GStreamer 1.18, Meson has been chosen as the only build system for the official GStreamer repositories. Taking advantage of the flexibility of the rising Meson build system, gst-build has been implemented to replace gst-uninstalled and provide a quick and smooth environment to hack into GStreamer and its dependencies. In order to improve this situation, gst-build was born.

It can also create builds for Android and iOS.ĭespite a shell environment allowing artifacts testing, Cerbero is not really convenient for a day to day development related to GStreamer as a new plugin development or a bug fix as it is not easy to update to the last revision without loosing a current work, or to test another branch of GStreamer The rise of gst-build: Indeed a Linux regular desktop host will be capable to cross-build GStreamer for x86(32/64bits) but also for architecture such ARM and system such as Microsoft Windows. Cerbero is written in Python and can create builds for the host machine like gst-uninstalled but also for various common targets depending on the host.

This solution offers a wide range of options in addition to a proper sandbox to avoid system dependencies and to be able to prepare packages that include third party software dependencies for a given version. But it was not as good at providing a real swiss-army knife approach to build GStreamer and its dependencies.Īnother build system called cerbero, created a few years ago, provides a standalone solution to build GStreamer packages. Although this tool was not very flexible and was missing some options in the command line, it was good enough if you wanted to tackle a surprising bug in our favorite framework.
So, a unified tool/build system has always been necessary to build a specified version.įor over a decade, a script named gst-uninstalled was present in the gstreamer/scripts directory to build the whole solution. This pipeline uses omxh264enc hence your design must have VCU encoder.GStreamer relies on multiple repositories such as base and good to build its ecosystem, and now owns more than 30 projects in Gitlab. This is an example pipeline to demonstrate ROI feature. The vvas_xroigen plug-in creates the ROI metadata from the incoming bounding box information and passes this metadata to omxh264enc for ROI based encoding. The inference operation generates the metadata and bounding box, for each detected object. The output from vvas_xmultisrc goes to the vvas_xfilter plug-in for object detection using the densebox model. If your design has other kernels, like multiscaler, for re-size and colorspace conversion, then you may use it along with vvas_xabrscaler plug-in. The output of the decoder goes to the vvas_xmultisrc plug-in for resizing to a resolution of 640 x 360 and color-space conversion to BGR format.

The qtdemux extracts the H.264 elementary stream from the MP4 container and pass it to the omxh264dec plug-in for decoding. The following pipeline takes input video in an MP4 container from the filesrc plug-in. The following table lists the GObject properties exposed by vvas_xroigen plug-in.
