The data reader, the data writer and the subsampler are meant to be independent components. They should be implemented independently to make it easy to test and benchmarks them. However for performance reason we may want to let underlying libraries (eg ffmpeg or yt-dl) handle multiple responsibility and hence we can introduced fused components. For example we may fuse multiple subsamplers into a single one, or we may even want to fuse a reader and a subsampler. These fused components will behave the same as using a composition of 2 independent components but may be faster.
DoD: one fused component has been implemented, and performance comparison was done
yeah would be a good time, most obvious fusing at this point would be creating the "FFmpegSubsampler" which can do:
- fps
- clipping
- resolution
all together
we should also fuse workers
