hi3518Ev200 使用vpss拓展通道帧率不对
我使用sdk是Hi3518E V200R001C01SPC021, sensor是720P的 9732 , 使用vpss拓展通道放大成1080P之后, vpss通道的帧率不正确,
1.使用vpss拓展通道的帧率情况:
720P: (没有放大的时候)
vi ----> vpss ----> venc
FrameRate: 25 17 14
1080P:(放大的时候)
vi ----> vpss ----> venc
FrameRate: 25 14 9
2. 不使用vpss拓展通道的帧率情况:
-------------------------------VPSS CHN OUTPUT RESOLUTION---------------------------------------------------
GrpID ChnID Enable Width Height Pixfmt CompressMode FrameRate
0 1 1 1280 720 SP420 0 25
0 2 1 640 480 SP420 0 25
0 4 1 1280 720 SP420 0 0
问题一: 为什么在使用了vpss 拓展通道之后, vpss通道的输出帧率会降下来, 并且在venc编码通道还会继续降帧, 而不使用vpss拓展通道的话, 在vpss通道和vence通道都不会有降帧的情况出现??
问题二: 使用了vpss拓展通道,并放大到1080P之后, vpss通道的输出帧率会又降一点, .
