I've had to search and experiment to get things to work at all, and the Nvidia "support" forum was no help. I've also found the information from Nvidia to be very poor, often misleading, and sometimes wrong.
Once you know the secret magic formula to do this it will work, but there is extra overhead for uploading and downloading frames. Mixing "standard" and Cuda filters is very far from obvious, and you have to specify uploading every frame to the hardware, use the Cuda filter, download every frame back, and then use a "standard" filter or filters. Mixing Intel and "standard" filters requires no effort at all, you just use whatever filters you want. In addition, for what the accelerated filters can't do you have to use the "standard" filters. The vpp_qsv filter alone can do a lot of processing that would take multiple filters otherwise, and it will do things no Cuda filter can do. Next, there are many more filter options available for Intel / QSV than for Nvidia / Cuda. And if you have a laptop you may not be able to upgrade at all. To use Nvidia / CUDA or AMD you need to have add a graphics card not all of them support hardware acceleration, and you can't upgrade all systems because there might not be enough power, or enough slots. This also includes "low power" processors built into laptops (I found out I have one such system). It's built in to the processor, you don't have to buy anything extra. I know now quite a bit more on the subject and would like to share it.įirst, and possibly most important: if you can only support one architecture it should be Intel Quick Sync (QSV) for several reasons.įirst: there are literally millions of computers in use today that have QSV, though many people don't know it. I've been doing a lot with hardware accelerated encoding and filtering, and I've been trying to obtain more information on this subject in other forums (and receiving mostly abuse for my efforts).
I apologize for not being here for a while, it's a lot longer than I realized.
