Description Sven Gothel 2020-01-03 02:24:58 CET

Currently our FFMPEGMediaPlayer only supports FFmpeg up to version 3.

Support using the current FFmpeg version 4.*,
which is used in Debian-10 and other distributions today.

+++

Also take care of optional non-system ffmpeg libraries,
potential packaged w/ JogAmp. 
For this, we should provide a choice via properties and 
allow loading an internal library name upfront, e.g. 'internal_avutil'.
This will also resolve Bug 1356.

jogl commit 2be7001101dbb16e5264c9c38b9764ba1e39ab5c

Bug 1420: Add FFMpeg 4.* versioned lib-names and provide optional internal lib lookup
    
New property 'jogl.ffmpeg.lib' may be set to 'internal',
setting PREFER_SYSTEM_LIBS:=false (default it true)
    
Non system internal libraries are named 'internal_<basename>',
e.g. 'internal_avutil'.
    
System default libraries are named '<basename>',
e.g. 'avutil'.
    
If PREFER_SYSTEM_LIBS is true (default),
we lookup the default library first,
then the versioned library names and last the internal library.
    
If PREFER_SYSTEM_LIBS is false,
we lookup the internal library first,
then the versioned library names and last the default library.

commit 2ecf00d7733c473358b652c50b83cb95f65174ff

    FFMPEGMediaPlayer: Add implementation update for FFmpeg version 4.* (Debian 11), 5.* (Debian 12) and 6.* (Current Development trunk)
    
    From here on, libav support has been dropped.
    
    Required FFmpeg libraries to be fully matched by their major runtime- and compiletime-versions are:
    - avcodec
    - avformat
    - avutil
    - swresample
    
    Library avdevice is optional and only used for video input devices (camera).
    
    Library avresample has been removed, since FFmpeg dropped it as well in version 6.*
    and swresample is preferred for lower versions.
    
    The matching major-versions of each library to the FFmpeg version
    is documented within FFMPEGMediaPlayer class API-doc.
    
    Each implementation version uses the non-deprecated FFmpeg code-path
    and compilation using matching header files is warning-free.
