nvidia dali video decode from external_source buffer (instead of file)

331 views Asked by At

This article explains how to do image decoding and preprocessing on server side with Dali while using triton-inference-server.

I am trying to find something similar for doing video decoding from h.264 encoded bytes array on server side, before the input "NTHWC" array is passed to any of the video recognition models like in mmaction2 or swin-transformer, using ensemble model.

All I can find is how to load video from files, but nothing on loading videos from external_source.

Also, as a workaround, I guess I can do the desired thing using python-backend by writing the encoded video bytes to a file, and preprocess the video, but that will not inherently support batch processing, and I will either have to handle the batch sequentially or by starting multiprocess pools for processing each batch. highly un-optimal I guess.

Any help is highly appreciated.
