Hallo Erik and List! Did you already have some progress in implementing ALAC support ? I just tried to compile the Apple source code and run into some problems: - First the makefile did not work, see [1] - According to this thread [2] the encoded files don't even play in iTunes - they have a new "magic cookie" and I did not find any compatible player (ffmpeg seems to have a fix now [3]) Someone in the hydrogenaudio forum added some fixes: - see [4], code is at http://perkele.cc/software/ALAC - for linux you have to change ag_dev.c (line 113, remove "{") and ag_enc.c (line 88, remove "{") - however, that seems to be mostly for windows, I am still not sure if the encoded files are correct ... I am just curious if you had some progress, otherwise I will do some more experiments ... Thanks for any hints!
