Can you tell me what settings you use in dvtb? I've run it through with
the following settings, and it still only gives me 11ms/frame. This is
one of the 640x480 sample yuv files supplied in dvsdk 2.00.00.18:
./dvtb-r
setp videnc1 codec mpeg4enc
setp videnc1 encodingPreset 6
setp videnc1 rateControlPreset 1
setp videnc1 maxHeight 480
setp videnc1 maxWidth 640
setp videnc1 maxFrameRate 30000
setp videnc1 maxBitRate 2000000
setp videnc1 dataEndianness 1
setp videnc1 maxInterFrameInterval 1
setp videnc1 inputChromaFormat 4
setp videnc1 inputContentType 0
setp videnc1 reconChromaFormat 1
setp videnc1 inputHeight 480
setp videnc1 inputWidth 640
setp videnc1 refFrameRate 30000
setp videnc1 targetFrameRate 30000
setp videnc1 targetBitRate 2000000
setp videnc1 intraFrameInterval 1
setp videnc1 generateHeader 0
setp videnc1 captureWidth 640
setp videnc1 forceFrame 0
setp videnc1 interFrameInterval 1
setp videnc1 mbDataFlag 0
setp videnc1 numFrames 300
func videnc1 -s foreman_vga_422i.yuv -t mp4-encode.mpeg4
This is all being done using the following kernel version:
$ uname -a
Linux snapper 2.6.18_pro500-davinci_evm-arm_v5t_le #1 PREEMPT Mon May 4
10:37:58 NZST 2009 armv5tejl unknown
We are using the cmemk & dm350mmap drivers from dvsdk_2_00_00_18. Is
there a different version of these I should be using?
Regards,
Andre
