6c9eac1998 avconv: don't set output width/height directly from input value. 
Always take it from lavfi. This way we don't need a clearly defined

2e21526790 avconv: change {input,output}_{streams,files} into arrays of pointers. 
Right now, they are arrays of structs, reallocated when new
streams/files are added. This makes storing pointers to those structs
harder than necessary.
