It's still noisy. The file is attached.

Hi!

Yep! A guy is sitting on a bench feeding a bird weird stuff, and also hitting it with a racket :)

feed.swf still plays noise.
It's likely parser related more then media-handler, as ffmpeg
had the same problem.

much closer to 0.8.1 as far as I can tell.
only tested those 2 ones.
I guess we can close this one if we have another bug for ADPCM parsing/decoding (and if you confirm these two tests are ADPCM related)

I committed a new patch which improves adpcm decoding even more. Please test with your various files.

Magical trevor worked before too.
I still have the noise for both feed.swf and 568db6323c3109f.swf

I tried with 0.8.1 and yes I can still ear some noise with feed.swf, but less, and much less noise with 568db6323c3109f.swf

Magical Trevor works for me again after that patch.

I committed a patch that I think will solve some of these noise issues. Feel free to test.

I confirm sound is fine with 0.8.1 and not with head.
BitsReader will loop around the buffer when trying to read beyond (tgc asked in irc).

I've changed back to using our internal ADPCM decoder, but i don't think it's improving...
Btw, i didn't get more noise with ffmpeg-libmedia than before, maybe ffmpeg has had a recent improvement.

Similar issue with this:

Magical trevor seems fine:

The testfile:

0ecb986f13a8d5bbc50769dc566d7c86 swf3/568db6323c3109f.swf

I'm pretty sure it used to work before libmedia.
