Option to choose output color format

🚀 The feature

Hi is it possible to stop the decoder from converting a video from bgr to rgb?

Motivation, pitch

Sometimes it is better to keep the images in bgr especially if running a live system at fast speed because cameras usually output frames in bgr. I would like the decoder to replicate that behaviour.

Hi @jc211 , videos are usually stored in YUV or some kind of chroma-subsampling format, so it's neither natively RGB or BGR.

We don't allow to convert the RGB to BGR, but you can do so very easily by calling e.g. permute() on the output tensor.

Ah ofcourse, I guess what I was asking is to choose the format it converts to to avoid double processing.
