Also, the formats that you have specified, are already compressed formats. Do you mean to say
you want to transcode? If you are transcoding videos, there are various other factors on which
your output video file size will depend.

Thanks and Regards

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

Subject: video compression

how to compress the video using hadoop

input : any type of video file (.flv,.mp4,.3gp,etc....)
output : compressed video file with customized format having less size than input video file.


is there any api.
