Arthur R Longbottom 1fe5e3f86c Fix VideoFromComponents.save_to crash when writing to BytesIO ... When `get_container_format()` or `get_stream_source()` is called on a tensor-based video (VideoFromComponents), it calls `save_to(BytesIO())`. Since BytesIO has no file extension, `av.open` can't infer the output format and throws `ValueError: Could not determine output format`. The sibling class `VideoFromFile` already handles this correctly via `get_open_write_kwargs()`, which detects BytesIO and sets the format explicitly. `VideoFromComponents` just never got the same treatment. This surfaces when any downstream node validates the container format of a tensor-based video, like TopazVideoEnhance or any node that calls `validate_container_format_is_mp4()`. Three-line fix in `comfy_api/latest/_input_impl/video_types.py`.		2026-02-27 10:27:28 -08:00
