Design Process : Data Backend

handle all files lumiera uses at runtime (media, edl, temp data)

manage filehandles, lumiera might use more more files than available filehandles

manage temporary data

do caching

io will be blocked where the backend tells the core where it can expect the data (not read()/write() like)

kindof garbage collector

do prefetching

no/low latency for the core the prefetcher and other things ensure that data is available in time

translate any input into a format which the lumiera core understands (demux, decode)

same for encoding to output formats

offer a plugin API for encoders/decoders

maybe network backend for serving data to distributed rendernodes

can do some load control or management (trigger adaptive rendering if system is idle etc)
