Incompatibility with recent versions of ffmpeg

[hsenot]

Hi there,

While the install guide does mention ffmpeg 2.6 as the tested version, actually compiling ffmpeg 2.6 with --enable-shared is quite hard due to the multiple dependencies ffmpeg has on different libraries.

Basically, I ended up not being able to compile at all older ffmpeg versions (2.6, 3.0), and encountering issues while compiling veejay-core against ffmpeg 4.4 (error mssages around AVStream API having changed from 'codec' to 'codecpar').

Rather than battling for compiling old ffmpeg versions, I was wondering if you had plans to support more recent versions of ffmpeg (say 4.x). My naive attempt at replacing 'codec' with 'codecpar' in veejay-core's avhelper.c ended up in segmentation faults (core dumps) when running veejay with a video file (though the dummy mode was running ok).

Is there debugging information I can provide (am not familiar at all with core dumps :-/ )?
Thank you!
