[mythtv] Mythweb - Flash Streaming

[Will Tatam]

The default list of options passed to ffmpeg are long over due for a
refresh, the options I use are

-ar 44100

Why use 11025 by default, it sounds horrible. Users can put up with a
grainy picture, but if the speech is muffled then the content is unwatchable

-vcodec libx264

x264 is way better than default codec, flash on the wii will  not
support x264 but this could be detected though the user agent thereby
removing the need to cripple the content for everyone just for the sake
of one platform

-aspect 16:9

I can't speak for other countries, but in the UK the majority of content
has been 16:9 for years, so if it's not possible to set the aspect ratio
based on the source, please default to 16:9 rather than 6:4

-threads 0

Tells ffmpeg to automatically detect the  number of cores and start the
optimum number of threads rather than defaulting to single thread when
dual and quad core are commonplace
