After upgrading from 10.6 to 10.7beta2, a52dec produces loud squelch noises along with audio track #97

Using the same source file, playing back ac3 audio from an mpeg2ts file on 
10.7beta2 produces mostly loud squelching/screeching noise, along with the 
(barely audible) audio track of the file. Playback in 10.6 is fine.

Can you attach a sample that reproduces the issue?

Here it is.

I can definitely hear the screeching, but I can't get audio to play in windows 
media player and the video won't even play in quicktime. Is there possibly an 
encoding issue?

Have you submitted this upstream as well? Have you tried it on linux w/ gst git?

The file was taken directly from a television broadcast. If I play back in 10.6 
there is no problem with the audio, so I don't know if that means that it's 
possible that the file is corrupt or not.

Please, check that you are using the same audio sink in both version, the 
directaudiosink is broken IIRC

I am. I tried waveformsink as well as outputting the audio to a file (with and 
without encoding it first), and it has the same problem. I think the problem is 
actually a52dec because every file I have that has ac3 audio has this problem 
with 10.7beta2. I have not submitted anything upstream nor am I able to try 
linux. I will upload some more samples in case you were concerned about it 
being the particular file I had.

@David: Can you reproduce it with the latest build? I was unable to compile the 
last sources, because the update requires latest liborc, and I need to rebuild 
all the deps (my windows machine is extremely slow and I'll have to wait a 
couple of days)

It looks like the last build of liba52dec is broken. Replacing this library 
with the one of 0.10.6 build fixes the issue.

I have reverted liba52-0.dll for the release (see r925)

GoogleCodeExporter commented 9 years ago

I can reproduce it. I should get a correct build, though. Just curious, why 
would you need to rebuild all the deps? We already have most of them built. :D

GoogleCodeExporter commented 9 years ago

Because I deleted accidentally the build folder, and from time to time a 
rebuild everything from scratch. But you are right, no need for that :P

I believe this is resolved for now.
