Recently I got an audiobook in m4b format, but I wanted to play it on my mp3 (only!) device. So, had to convert it. To do this, on my Debian Lenny box I first: apt-get install ffmpeg libmp3lame30 libfaad0 libavcodec51 The last one seems to be the most important, nothing works even though libavcodec51 wold seem to have nothing to do with mp3 encoding... Then used a bash script: #!/bin/bash for i in *.m4b; do ffmpeg -i "$i" -acodec libmp3lame "${i%m4b}mp3"; done to convert all the m4b files in a directory. Later, I used easytag to add tags to the mp3s so they would show up properly on the device {770}. Simplest way to get this to work was to just change the name of the containing folder to Artist - Title; didn't want to manually change the tags on all the mp3's, and I didn't find a 'apply all' button. | ||

During the GOSH! summit there was an intensive talk about making a open-hardware USBkey-to-television converter/computer/mp4 player, an idea (patented!) by Joshua Kauffman and Gwendolyn Floyd. Since this was a very hands-on workshop, I decided to get an mp4 player in downtown Banff and take it apart to see how it works. The selected device, a RCA Lyra MC4202-A portable media player, is, in accordance with its low price, electrically simple on the inside. What follows is a rough teardown of the internals. -- View of the Lya with the back plastic panel removed.
