hi all,
i'm using the fmlecmd.exe file also fmle 3.2 windows version (tried 3.1 too) to publish my video from a windows 7 os.
the video source is a MediaLooks video mixer, which use a Panasonic DV camera as a source (camera -> mixer -> fmle)
currently the mixer output the video at 25 fps, but in the fmle there are more choices.
now setting the fmle to 150kbps at 25 fps creates (measured by netlimier or perfmon) a 20000 Bps stream (more or less 150kbps)
setting the fmle to 150kbps at 15 fps creates a 32 kBps stream (more or less 250kbps)
setting the fmle to 150kbps at 30 fps or higher make the stream just a little lower at 19.5 kBps.
setting the mixer to output the video at 15 fps will make the fmle :
set at 150kbps and 15 fps to publish at 20000 Bps (~155kbps)
set at 150kbps and 25 fps to bpush at 19,500 Bps (~150kbps)
set at 150kbps and 10 fps to publish at 28000 Bps (~215kbps)
in simple calculation when the fps is lower the published video uses a <setted birate> / <target fps> * <origin fps> instead of (in my understanding) using the same bitrate and sending less frames (so the quality will be better)
from my understanding thats an unexpected result.
i read here in some other discussion that the fmle doesn't really know to change the source (which is the mixer here) fps, is that true? even so why is the bitrate going up when lowering the fps?
Any help is appreciated!
