Changing video_format_t (and thus es_format_t and picture_t) affects 
access_demuxes, demuxes, packetizers, decoders, video filters, spu sources, spu 
filters, encoders, visualizations, vout splitters and vout displays... 
Personally I am unable to review such an invasive change within any meaningful 
time frame.

Breaking the binary interface is no longer an option for 2.2 releases so you 
would need to change the bug milestone in any case.
