[MPlayer-dev-eng] Fast Forward and Slow Motion Patch

[Struan Bartlett]

Dear Arpi, Jonas, Fabian, et al,

Thanks for your positive feedback.

You've convinced me I need to at least mute the audio during fast 
forward / slow motion.

Myself, I didn't experience poor resyncing of A/V after reverting to 1x 
playback. After all, I'm just using the existing seek code, so I don't 
understand how it could be worse than unpatched code (I don't always get 
perfect A/V sync anyway!)

I'd love to attempt the reconfigured audio filters, but that job seemed 
much more difficult, as it I reckoned I would need to break out the 
audio filter config code into a separate function to avoid duplication.

I would like to try the muted audio and get back to you.

Kind regards,

Struan
