[Bug] OOM Killed

[lawliet89]

I noticed that when the tool tries to download one whole day of continuous footage (daily) from a 4K camera, it takes a long time and eventually it gets "Killed". The output file was zero bytes.

I haven't confirmed this with the code, but it seems like the whole file content is buffered in memory before writing to the filesystem.

The tool should stream from the URL to the final file instead of buffering into memory.
