Vivia Nikolaidou b90d02741e avviddec, video.c, h265parse: Workaround for broken field-based interlaced encoders
Some encoders (e.g. Makito) have H265 field-based interlacing, but then
also specify an 1:2 pixel aspect ratio. That makes it kind-of work with
decoders that don't properly support field-based decoding, but makes us
end up with the wrong aspect ratio if we implement everything properly.
As a workaround, detect 1:2 pixel aspect ratio for field-based
interlacing, and check if making that 1:1 would make the new display
aspect ratio common. In that case, we override it with 1:1.

gst-libav

This module contains a GStreamer plugin for using the encoders, decoders, muxers, and demuxers provided by FFmpeg. It is called gst-libav for historical reasons.

Plugin Dependencies and Licenses

GStreamer is developed under the terms of the LGPL-2.1 (see COPYING file for details), and that includes the code in this repository.

However, this repository depends on FFmpeg, which can be built in the following modes using various ./configure switches: LGPL-2.1, LGPL-3, GPL, or non-free.

This can mean, for example, that if you are distributing an application which has a non-GPL compatible license (like a closed-source application) with GStreamer, you have to make sure not to build FFmpeg with GPL code enabled.

Overall, when using plugins that link to GPL libraries, GStreamer is for all practical reasons under the GPL itself.

The above recommendations are not legal advice, and you are responsible for ensuring that you meet your licensing obligations.
