Bug Description
I'm on Ubuntu 10.04.1 LTS (64bit)
My libfaad2 is v 2.7-4.
This stream is from my local radio station: http://
This stream plays properly on a mac on VLC; but on Lucid it has the a popping and warbling glitch that happens every second or so. Playing with mplayer, totem, gst-launch, mpd, vlc (which all seem to use libfaad2) all have the same problem. (I'm guessing that VLC on OSX uses system-native AAC decoding?)
I ruled out the network transport layer and audio configuration problems by using command-line tools like wget. I'm attaching "out.aac" that contains a good squeek sound for example. Note that faad can't do anything with this file, but the clients that use libfaad can decode it.
I installed ffmpeg, and converted the stream into a wav file, which plays flawlessly.
"mplayer out.aac" --> <squeek !>
"ffmpeg -i out.aac ffmpeg.wav"
"mplayer ffmpeg.wav" --> <perfect>
There's another bug #575798 against FAAD2 that may be related.
I noticed that the clicks and pops happen less when the audio is simple (like when someone is talking rather than music playing)... perhaps this is a clue.
