Summary

• multimedia/avidemux-qt4:

[...]
/wrkdirs/usr/ports/multimedia/avidemux-qt4/work/avidemux_2.6.11/avidemux/qt4/ADM_jobs/src/ADM_jobControl.cpp:115:58: error: unable to find string literal operator 'operator""y' with 'const char [8]', 'long unsigned int' arguments
define MX(x,y) case ADM_JOB_##x:  status->setIcon(QIcon(":/jobs/"y));break;
[...]

• multimedia/avidemux-plugins:

[...]
/wrkdirs/usr/ports/multimedia/avidemux-plugins/work/avidemux_2.6.11/avidemux_plugins/ADM_demuxers/MpegTS/dmxTSPacket.cpp:436:49: error: unable to find string literal operator 'operator""x' with 'const char [30]', 'long unsigned int' arguments
#define fail(x) {printf("[Ts Demuxer]*********"x"*******\n");return false;}
[...]

avidemux-plugins needs some more work as it also fails with

/wrkdirs/usr/ports/multimedia/avidemux-plugins/work/avidemux_2.6.11/avidemux_plugins/ADM_videoEncoder/ffMpeg4/ADM_ffMpeg4.h:74:1: error: narrowing conversion of '-2' from 'int' to 'uint32_t {aka unsigned int}' inside { } [-Wnarrowing]

I'll update the diff later...

https://github.com/mean00/avidemux2/commit/68df30b902540e6f299dc63ea3ae53b3d353cbe4 contains a fix for the narrowing, probably.
