Hi guys,
I am trying to use NVDEC to decode H264 video frame (1920*1080) encoded by OpenH264 , but found the performance is worse than OpenH264 decoder:
NVDEC spent 5-6 ms to decode a frame, while OpenH264 spent 4-5 ms to decode a frame.
But when I tried to use NVDEC to decode H264 video frame (1920*1080) encoded by NVENC, performance is much better:
NVDEC spent 1-1.5 ms to decode a frame, while OpenH264 spent 2-2.5 ms to decode it.
I’m wondering:
- Does NVENC have any specific optimization comparing to OpenH264?
- Does NVDEC have any specific optimization for frame encoded by NVENC?
Thanks!
