See: e3dc2c86Merged-by: Michael Niedermayer <michaelni@gmx.at>

The rationale is that you have a packed format in form
<greyscale sample> <alpha sample> <greyscale sample> <alpha sample>
and shortening greyscale to 'G' might make one thing about Greenscale instead.
An alias pixel format and color space name are provided for compatibility.

Merged-by: Michael Niedermayer <michaelni@gmx.at>

This makes the default of '1' more explicit than defaulting to '1' in
fate-run.sh and regression-funcs.sh if THREADS is not set.
Fixes the reported thread count in fate-cpu if THREADS is not set.

Icecast is basically a convenience wrapper around the HTTP protocol.

Not merged, the error messages are not about missing support of features
of the input file. avpriv_report_missing_feature() speaks about
"... your file has a feature which has not been implemented"
Thats would simply not be correct
