c04c52d3a8 Additional checks for strange num_val in FLV metadata 
Avoids some "Unsupported audio codec (6)" message in FLVs, e.g.
        Example of such problematic bitstream is 'bad_codec6.flv'
        in ftp's /incoming directory.

58293e57e1 Fix issue357 
Do what the spec says, insane or not:
"
Format 0 (uncompressed) and Format 3 (uncompressed little-endian) are similar. Both encode
uncompressed audio samples. For 8-bit samples, the two formats are identical. For 16-bit
samples, the two formats differ in byte ordering. In Format 0, 16-bit samples are encoded and
decoded according to the native byte ordering of the platform on which the encoder and Flash
Player, respectively, are running. In Format 3, 16-bit samples are always encoded in little-endian
order (least significant byte first), and are byte-swapped if necessary in Flash Player before
playback. Format 0 is clearly disadvantageous because it introduces a playback platform
dependency. For 16-bit samples, Format 3 is highly preferable to Format 0 for SWF version 4
or later.

44de39f93c flv/swf do not have a big endian codec id, they only support 
little endian and native endian.

f84c357325 Add support for VP6A in flv. 
Those files really contain 2 standard VP6 video streams:
 - the "normal" video stream
 - the alpha plan video stream (which is a standard
   YV12 video with it's U an V plans all set to 0)
closes issue166
