RE: video compression

Hi Mallik,

This is a good wish list, but there are challenges around running compressions across a hadoop cluster. Not all compression algorithms are suited for running through map-reduce, since most of the compression algorithms are very much context driven and tree based, so its hard to break them across various map-reduce tasks. LZO compression is however a parallel compression algorithm and has can be run in a map-reduce paradigm. The video compression however are different, and whether they can be achieved via map-reduce is something that will depend on, as to how much parallel compression the specific video compression algorithm supports.

Thanks and Regards
Pankaj Misra
