It can actually be useful if you can't use libavcodec api (eg due to missing bindings from another language) or if you want to just parse avconv output. Also this output is very specific (since you have to specify -h codec=name), so I don't think it's going to confuse users, but just provide more details. -- Vittorio _______________________________________________ libav-devel mailing list [email protected] https://lists.libav.org/mailman/listinfo/libav-devel
