Trying to build a real-time transcoding farm based on FFmpeg + NVENC.
I see many bench marks report on encoding frame rate, but not sure on
how they scale when the number of encoding processes increase.
I would appreciate advise from those with insight on the following.
As of today, what is the most affordable NVIDIA card that allows 3 or
more instances of FFmpeg + NVENC to run?
In the case of the following application, roughly how many instances can
I expect to run simultaneously?
CPU: A single modern Core i7 (Rather than multi CPU)
OS: Windows or Linux
Input: MPEG2 or H.264, Mainly SD but occasionally HD
Output: H.264, SD
Other: De-interlace. Quality has priority over latency.
Any other bottlenecks/pitfalls I should be aware of?
