Comment:
What are you trying to achieve?
alac is a proprietary (in the sense of "published by a company, not by a
standard committee or similar") audio codec that can only be read by a
limited number of software (either QuickTime- or FFmpeg-based). FFmpeg
supports muxing alac in mov and caf. (avi could possibly be supported, but
how would you read the resulting file?)
Transport Streams are not general-purpose containers (like avi), but allow
only a very limited set of codecs, see
