GStreamer pops on 22050Hz MP3
Last modified: 2009-08-10 23:24:31 UTC
Please describe the problem: Playback of MP3's recorded at a 22050Hz sample rate produce audio with hisses and pops. Steps to reproduce: 1. Find or create an MP3 encoded with a 22050Hz sample rate. 2. Play it in RhythmBox 3. Hear pops and hisses. Actual results: I hear pops and hisses. Expected results: To hear beautiful music. Does this happen every time? Yes Other information: I was able to work around by edit the MP3 in Audacity and resampling to 44100Hz. I tried different bit rates before I discovered it was an issue with the sample rate. Email me and I can send a sample problem file.
Which versions of gstreamer core, plugins-base and plugins-ugly do you have installed? Also are you using the mad or the fluendo mp3 decoder plugin? What's your audio setup (pulseaudio, alsa, ...)?
dpkg -s libgstreamer0.10-0 | grep Version Version: 0.10.22-1 dpkg -s gstreamer0.10-plugins-base | grep Version Version: 0.10.22-5 Gstreamer-Version: 0.10 dpkg -s gstreamer0.10-plugins-ugly | grep Version Version: 0.10.10.2-1build1 Gstreamer-Version: 0.10 As for the mp3 decoder, I don't know how to check that one. dpkg --get-selections | grep mp3 libgmp3c2 install libmp3lame0 install dpkg --get-selections | grep gstream bluez-gstreamer install gstreamer0.10-alsa install gstreamer0.10-ffmpeg install gstreamer0.10-gnomevfs install gstreamer0.10-plugins-bad install gstreamer0.10-plugins-base install gstreamer0.10-plugins-base-apps install gstreamer0.10-plugins-good install gstreamer0.10-plugins-ugly install gstreamer0.10-pulseaudio install gstreamer0.10-schroedinger install gstreamer0.10-tools install gstreamer0.10-x install libgstreamer-plugins-base0.10-0 install libgstreamer0.10-0 install totem-gstreamer install So, I guessing ffmpeg? I'm not entirely sure how to check the audio setup but the last thing on tty1 is "* PulseAudio configured for per-user sessions [ OK ]" Curiously, it sounds like a blown speaker except that it sounds perfect on 44100Hz mp3's. What else can I do to help out?
Hm, could send me a file that shows this behaviour at slomo@circular-chaos.org ?
I can't confirm this with the file you sent to me. Could you try with newer versions of GStreamer as used in the latest Ubuntu release (you seem to be using Ubuntu, if not try to find newer packages for your distribution ;) ).
According to Synaptic, I have the most recent Ubuntu packages but there's newer ones at gstreamer.freedesktop.org. Which components should I manually upgrade? libgstreamer, gstreamer0.10-plugins-base, and gstreamer0.10-plugins-ugly?
You can install newer packages from this PPA: https://launchpad.net/~gstreamer-developers/+archive/ppa
Ah, sweet. There's still a small pop when starting 22050 songs and when skipping around but it's leagues better. Thank you. :D
