FlashVSR - OOM on 32GB VRAM on long videos

[jnpatrick99]

FlashVSR is supercool, I love the quality. On my RTX 5090 I get OOM if setting video frames to more than ~100. Is it possible to workaround? I tried setting context size to 77 frames, it went through WanVideo Sampler but then crashed with OOM on WanVideo Decode. If original frames number is ~77 it goes through all nodes very well.
Is there a way to upscale long videos?

I experience the same! Maybe allow the decoder to decode frames in windows for long videos, when it detects WanVideo Context options is being used?

@kijai Thanks for your amazing work! I proposed the following PR #1443 to fix that issue. Please let me know if it works that way - implemented chunked decoding/context windows support for long FlashVSR videos.
