Hi everybody,

  here is the problem, when I set SwMsLink_CreateParams.numOutBuf to littler than default, and maxInputQueLen to  16, it will cause drop frame. what's the relatives between input and output buffer number?

    Hi,

    If buffers are not available at the output of software mosaic, and the input channel queue has more than 3 frames(in case of SC mode) and 4 frames(in case of DEI and SC mode), it will drop the extra frames in the queue provided AVSync is not turned on. 

    I would suggest increase the number of output buffers to atleast 5 if not 6, as 2 buffers will be consumed by display link and 2 by SwMs link, which leaves 1 or 2 frames free in the output queue so that input frames(in SwMs) are not dropped due to lack of output buffers.

    Regards,

    Arun
