Is there a very efficient audio/video reader in matlab?
Nowadays, with the popularity of deep learning video understanding, all kinds of task data generally exist very large, as little as a few thousand videos or as many as a million videos. ", "videoReader","fileDatastore","imageDatastore" and other functions can perform video-level operations without running out of memory, but the problem is that many bottlenecks in deep learning occur in video IO, and matlab is not efficient at reading and processing using the above functions. The decord module (underlying C++) is available in python, will a future version of matlab introduce a similar efficient module?
