ffmbc: stereo to 2-mono-streams in MXF OP1a

Haven't verified it completely yet, but this should create a proper XDCam HD422 MXF (OP1a) from a regular stereo source. Each audio channel from the source is mapped an individual audio stream in the output: $ ffmbc -threads 8 -i FILE_IN -s 1920x1080 -tff -target xdcamhd422 \ -acodec pcm_s24le -ar 4...

I remember that I've been using my Tascam US-122 audio/midi device on previous versions of (X|K)Ubuntu without problems. Unfortunately, the Ubuntu package maintainers are not allowed (for legal/copyright/patent reasons), to host the firmware binary blob of the US-122 anymore :( Because it's propriet...

xfce4-terminal: Disable F1 shortcut

There are some commandline applications that offer their help on pressing the "F1"-key. Unfortunately however, the xfce4-terminal application also has its help assigned to "F1". This makes sense, but it's more likely that one wants to call the F1-function of the application runni...
