Stream large media transforms instead of materializing full intermediates

Summary#

When a processing path expands compressed media into full in-memory tensors, peak RAM can scale with frame count rather than file size and turn ordinary uploads into OOM risks. Prefer a streaming pipeline for transcoding or conversion work, and reserve full materialization for cases that truly need random access or whole-buffer operations.

Problem#

A video transcode path buffered every frame in RAM, causing memory blowups on longer or higher-resolution inputs.

Solution#

Refactor the slow path to stream frames through the transcode pipeline incrementally, while keeping a fast remux/copy path for already-compatible sources.

Failure Modes#

Keeping hidden fallback paths that still decode the full asset into memory
Optimizing only the happy path while incompatible codecs still hit the old RAM-heavy branch
Missing regression tests for long videos, high resolutions, or partner integrations that always transcode
