Hi, The encoder allows you to set the MaxQp(0~51), MinQp(0~51), and MaxBitrate parameters. MaxQp and MinQp are used to controlpicture quality and MaxBitrate is used to clamp the maximum encoding bit rate within the bitrate statistical time; The default configuration is MinQp = 10; MaxQp = 40. If you could not get it to work for lower bitrates , please try to change MaxQp to a bigger value, then maybe reduce the qulity of the picture.

I could not get it to work for lower bitrates. After about 1.5Mb/s it stopped doing anything. I needed 500Kb/s for my application and was unable to get that. > > BR, > > -- > You received this message because you are subscribed to the Google Groups > "linux-sunxi" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to [email protected]. > For more options, visit https://groups.google.com/d/optout. -- Jon Smirl [email protected] -- You received this message because you are subscribed to the Google Groups "linux-sunxi" group.
