"iTunes Media Library reader" playlist demux shouldn't open for files it can't parse

When "iTunes Media Library reader" fail with "playlist error: invalid root node name" it should let lua playlist operate or rewrite itml in lua as j-peg said.

I don't see why. If it is an itml file, it should be parsed by itml.

If the root node name is invalid then it probably mean that it isn't a itml file.

The itml playlist demux would have to be modified to check this and fail in its open/probe function instead, earlier. If the itml demux claims to handle it, there's nothing the lua demux can do.

added Component::Demuxers: Playlist label

changed title from LUA: Lua playlist doesn't work when "iTunes Media Library reader" start to "iTunes Media Library reader" playlist demux shouldn't open for files it can't parse
