Description

Hi,

Currently I'm working on video tasks. In order to speed up the preprocessing time, I usually load all the encoded videos to the memory or the tfrecords. However, it seems I cannot find the relative ops in Dali. The VideoReader do the similar thing but it has to load the video from disks.

In this cases, I'm wondering is that possible to add the VideoDecoder ops to decode the video bytes in the memory by slightly changing the VideoReader ops. Also, seems crop is also supported for the video sequence, it would also be nice to add the VideoDecoderSlice ops as well.

Thank!
