+Crops select the same pixels as TorchCodec's. Since v0.4.2, `Resize` scales in YUV while converting
+to RGB, so it costs no more than native-size output; its pixels differ from TorchCodec's by about
+0.9 levels on average (see [resizing](docs/compatibility.md#resizing)).

 This TensorCodec extension selects by actual PTS and retries seeks that overshoot.
 It supports time queries, including ranges with explicit `fps`, but not frame
 indices, `len(decoder)`, or `get_all_frames()`. See [the contract](docs/compatibility.md#timestamp-mode).
