bitrate of the h264stream transcoded using vlc is not proper

[srikanthMadishetti]

Hi all,

I have tried transcoding the stream with following parameters.

vlc -I dummy vop85m3lfaj02w.mp4" --sout '#transcode{venc=x264{aud=1,non-deterministic,no-dct-decimate,no-fast-pskip,merange=24,asm=1,profile=baseline,vbv-bufsize=1024,qcomp=0.1,
qblur=1.0,direct=auto,keyint=15,min-keyint=2,me=tesa,vbv-maxrate=196,ipratio=1.40,no-psnr,bpyramid=0,qp=151,qpmin=0,bframes=0,no-cabac,
nf,level=1.0,crf=18,partitions=all},vcodec=h264,vb=256,acodec=mp4a,ab=32,samplerate=24000,channels=2,height=600,width=800,fps=15}:
std{access=file,mux=mp4,dst="a8001.mp4"}'

I have given target video bitrate as 256kbps in the above command. But the actual transcoded stream is having 2068 kbps video bitrate.
Please suggest any changes required to the above command or need to be set some extra parameters to transcode with the required video bitrate.

Thanks in advance.

IMHO vb=256 is senseless because you have defined the resulted bitrate with the venc=x264{<parameters>} parameters.
