RTSP cache/buffer

 Hi All,

I am trying do rtsp video streaming on my android device using media
player. works fine for both, h263 and h264. the only issue is, I am
getting around 3 to 4 second delay. I want to reduce it to less then a
second.

I have checked till depth, I cant find buffer or cache settings
anywhere. Is it default for media player? Is there any way I can
change it?

Is there any other option to play remote video without delay??????

If this limitation is from Opencore it self, there is no way android
can have by-directional video calling with its native libs.


Thanks,

Chirag

1. Problem of using switch_class for headset detection

Dear all,

I'm using switch_class driver for me to implement headset detection.
Below are my codes (roughly):
-------------------------------------------------------
enum {
        NO_DEVICE       = 0,
        HEADSET = 1,
};

struct hs_res {
        struct switch_dev sdev;

        unsigned int det;
        unsigned int irq;
};
static struct hs_res *hr;

In probe function:

xxx_probe()
{
        int ret;
        hr->sdev.name = "hs";
        hr->sdev.print_name = hs_print_name;

        ret = switch_dev_register(&hr->sdev);
}

In IRQ for dealing with detection gpio

hs_det_irq()
{
        state = gpio_get_value(hr->det);
        if (state)
                switch_set_state(&hr->sdev, NO_DEVICE);
        else
                switch_set_state(&hr->sdev, HEADSET);
}

This switch_set_state(&hr->sdev, HEADSET) action can be done while the
headset is inserted
first before power on the device.

I can set the state to 1 by switch_set_state(&hr->sdev, HEADSET), and
the audio path can be switched to my headset (music came from my
headset)

Howevere, if the headset is inserted after the device gets into
homescreen,  the switch_set_state(&hr->sdev, HEADSET) won't be done .

It pops up messages as below:
Anyone has idea about what's wrong is it?
