LG webOS 5.x GStreamer - Good Plugins

Description

This directory contains the gst-plugins-good source, as compiled by LG to be included in webOS 5.x devices, such as LG CX OLED TVs.

Thus, unless LG applied some changes that have not yet been published, the binaries produced by compiling the source from this repository should work as a drop-in replacement for the GStreamer binaries that are officially used by LG in their CX OLED Smart TVs.

This can be very useful if you have rooted your TV and want to alter this source to enable or restore functionality that is not provided by default on your CX model.

For instance, in this specific repository, we have also restored DTS demuxing from the Mastroska plugin, which LG's forcibly removed, on CX models, so that, provided that you also have a DTS audio decoder plugin, .mkv files with a DTS track can be played natively on your TV. For more on this, please see this thread from the RootMyTV issue tracker.

Origin

This source, which is licensed under LPGL v2.0, was obtained through a legal inquiry at https://opensource.lge.com/inquiry and was extracted from the webOS 5.0 JO 2.0 archive that can be downloaded here.

The changes that have been applied by LG on top of the official GStreamer 1.14.4 source can be found in this commit.

Compilation

Toolchain installation

You will need a recent Linux system, with some GTK related system updates as well as the webosbrew toolchain from https://www.webosbrew.org. On Debian 11, the toolchain can be installed as follows:

apt install cmake doxygen libglib2.0-dev-bin gobject-introspection libgirepository1.0-dev
wget https://github.com/webosbrew/meta-lg-webos-ndk/releases/download/1.0.g-rev.5/webos-sdk-x86_64-armv7a-neon-toolchain-1.0.g.sh
chmod 755 webos-sdk-x86_64-armv7a-neon-toolchain-1.0.g.sh
./webos-sdk-x86_64-armv7a-neon-toolchain-1.0.g.sh

Note that, if using the toolchain above, you should also have compiled and installed the GStreamer software from https://github.com/lgstreamer/gstreamer as well as the base plugins from https://github.com/lgstreamer/gst-plugins-base otherwise the process will complain that your version of GStreamer is too old.

Build process

Once the toolchain and GStreamer dependencies have been installed, you can compile these plugins by issuing:

git clone https://github.com/lgstreamer/gst-plugins-good.git
cd gst-plugins-good
. /opt/webos-sdk-x86_64/1.0.g/environment-setup-armv7a-neon-webos-linux-gnueabi
