The problem I found (so did everyone else) when updating to Ubuntu 9.10 Karmic was static/popping noises when your sound card is silent (aka goes into power-save mode). It applies to my Dell XPS M1530 laptop’s on-board sound and probably to the same chipset elsewhere. (more…)

Wow, ffmpeg is really great for converting multimedia.  Unfortunately, the support for MP3 audio doesn’t appear available by default.  Sure, it can decode MP3 audio and write to an MP3 container, but what about having an actual MP3 codec available?

sudo apt-get purge ffmpeg
sudo apt-get install libavcodec-unstripped-52 libavdevice-unstripped-52 libavformat-unstripped-52 libavutil-unstripped-49 libpostproc-unstripped-51 libswscale-unstripped-0 ffmpeg

As a little bonus, there’s a number of other codecs that come along with it too (xvid etc).  I’m not too fussed on them but now I can use `-acodec libmp3lame` as my audio codec and have the FLV outputted with MP3 audio.  There’s a problem with either the default FLV encoder or VLC not being able to playback the audio with default settings, but this seems to work.

That said, it remains to be seen if this’ll cause any problems with FLV playback, but the players I’ve used so far (web-based) seem happy enough.
