i am looking for some advice on high speed data compression of matrix data (video):
in my setup, i write and read video as single frames to a harddrive, currently as uncompressed uyvy binary .jxf data - which is fast but requires really fast disks as well. which is why i am now looking at compression.
- what sort of compression would be needed in my case? i tried with jpg/png/etc. but all this is way too slow. a friend recommended having a look at snappy/lzf/lzo - would that make sense? i found an implementation of lzo (sadam external) but did not get that to really compress anything...
- how would i read and write the then compressed data to disk? since matrices only support int or float i guess i would need something else to do that. something that would just dump a list into a file...?
as always, thanks a lot for any help!!
