Hmm, that's true. The problem i was trying to avoid here is that for most things you use a dedicated command to list them, for some others you use -command list, which is annoying both in code and usage. -list <foo> seems like a good idea. -- Anton Khirnov _______________________________________________ libav-devel mailing list libav-devel@libav.org https://lists.libav.org/mailman/listinfo/libav-devel
