[GATOS]km and ffmpeg test results

[benoit <b....@sy...>]

Bonjour,

Here is the outcome of some testing with km and ffmpeg if anybody
interested.
- km taken from Cvs 09 sept 2003,
- ffmpeg cvs snapshot 27 sept 2003.

Test 1. With these 2 version ffmpeg capture one frame every 15s or so.

I found out that ffmpeg has some special code to handle all in wonder.
Now I apply the following patch to skip this special code.

-        if (!strcmp(s->video_cap.name, "Km")) {
+        if (!strcmp(s->video_cap.name, "KmDummy")) {
             if (aiw_init(s) < 0)
                 goto fail;
             s->aiw_enabled = 1;

Just use a Dummy string so that ffmpeg does not activate Km specific
code.

test 2. run
./ffmpeg -s 640x240 -vd /dev/video0 -ad /dev/dsp -r 60 -b 1000
/tmp/toto1.avi 

Capture runs well. Playback with mplayer shows correct colors but motion
is not very smooth although audio and video are in sync.

Setup:
- Mandrake kernel 2.4.22-5 (From cooker),
- AIW 8500DV NTSC,
- P4 1.6 GHZ
- using oss drivers.

Bye,
Benoit
