[spook-l] Using spook with an hardware encoder

[Marco Buffa]

Hello to everybody.

I'm trying to use spook on an embedded board (Intel IXP425) running
Snapgear Linux.

I succeded in compilation with the arm toolchain, and spook seems to
run fine, but I'm in trouble with the spook.conf file.

I have an MPEG2/4 hardware encoder (wis go7007) mounted on my board,
with working V4L driver (the device in attached at /dev/video0), and
I'm using this spook.conf file:

-------------------------------------------
FrameHeap 30;
Port 7070;

Input V4L {
        Device /dev/video0;
        InputType webcam;
        InputPort 0;
        Framerate auto;
        FrameSize 320 240;
        Output "compressed";
}

RTSP-Handler Live {
        Path /test;
        Track "compressed";
}
-------------------------------------------

The problem is that when I launch spook with such configuration file,
I obtain this error:

Jan  1 00:01:03 spook[43]: live: no media sources specified!
-------------------------------------------

It seems that spook needs to "convert" the stream, but my stream is
already MPEG4 ES.
Where I'm wrong? I need a V4L*2* driver?

Thank you.
