1209806 - Remove dependency on libavformat

Status: RESOLVED FIXED

(Core :: Audio/Video: Playback, defect)

Description

[Jean-Yves Avenard [:jya]]

When searching for ffmpeg or libav we currently look for libavformat and search a specific version.

We have no use for the libavformat library as we only use libavcodec and indirectly libavutil.

The version numbering in libavformat is also completely irrelevant for our use.

We should look for libavcodec instead.

Interestingly, libavformat doesn't appear to be installed on ubuntu unless you install the full ffmpeg or gstreamer-ffmpeg plugin.

So currently to use Firefox with ffmpeg, you must install gstreamer-ffmpeg which is rather a pity

Rename |struct AvFormatLib|.

(Jean-Yves requested I do the review, as we're not sure whether Edwin is available at the moment.)
