"sub-source" was formerly "sub-filter", and now the "sub-filter" configuration may contain sub-filters or sub-sources configurations.
so if sub-filter configuration was provided but the sub-filter chain creation was failed, try to use the configuration as a sub-source configuration.

Tested on current libav and ffmpeg @ 25846 svn revision playback only.

all the "new" functions used arrived earlier than abovementioned
versions were published.

Some V4L2 devices (e.g. Hauppauge EXETER boards) compute the tuner
frequency depending on the configured standard, so the standard needs to
be set first.

Otherwise, use the normal default device even if the audio input format
is non-linear (VLC does A/52, DTS and MPGA to linear decoding as audio
filter rather than decoder).

This will be needed for special styling

FYI: GnuTLS seems to have moved beyond libgcrypt and uses libnettle now...
