reimar a4177fd581 audio: make AC3 pass-through with ad_spdif work
Do not fall back to 0 for samplerate when parser is not initialized.

Might fix some issues with using -ac spdifenc with audio in MKV
or MP4.

git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@35517 b3059339-0415-0410-9bf9-f77b7e298cf2

Replace outdated list of unsupported formats by list of supported formats.

git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@35534 b3059339-0415-0410-9bf9-f77b7e298cf2

Do not call af_fmt2str on the same data over and over.

git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@35535 b3059339-0415-0410-9bf9-f77b7e298cf2

ad_spdif: use the more specific AF_FORMAT_AC3_LE when
we handle AC3.

git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@35536 b3059339-0415-0410-9bf9-f77b7e298cf2

Make AF_FORMAT_IS_IEC61937 include AF_FORMAT_IS_AC3.

Our AC3 "sample format" is also iec61937.

git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@35537 b3059339-0415-0410-9bf9-f77b7e298cf2

af_format: support endianness conversion also for iec61937
formats in general, not just AC3.

git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@35538 b3059339-0415-0410-9bf9-f77b7e298cf2

Conflicts:
	audio/filter/af_format.c

af_format: Fix check_format, non-special formats are of course supported.
