Hi FSL Guys,
According the picture above, you will find there is a around 1 second delay between the iPhone and navigation unit on CarLife. But for Android phone, the delay time is200-300 ms. Baidu guys said the long delay of iPhone may by caused by i.MX6, USB or decoder. But i cannot where i can improve. Could you advise me the possible cause?
The function SetParametor with OMX_IndexParamVideoDecReorderDisable(OMX_DECODER_REORDER) is used to disable reorder.
