image capture from avi vfw device can't find video modes
Hello
Here my issu, i have implemented image capture from a video device using jmf 2.1.1e performancepack, using a webcam everything is fine but when i use the video capture source i want to use i can only work with format 720x480 pal and i require 720x576 pal.
jmf seem not to reconize video format from this source, but the video is correcty displayed and image correctly captured. I'm surprised it is half working:decoding&render is ok to but not format choice.
I have check it is not because i'm in ntsc mode (ntsc is 720x480) because my analogic source is pal and color are correct (if with device software i change to ntsc mode i have a black&with but using jmf i'm in color so i'm in pal mode)
Difference bettween the webcam and my device is that my device is an avi encoder so in jmf webcam is javax.media.format.YUVFormat and my device com.sun.media.format.AviVideoFormat
i have tried many thing:
install codec pack (divx6, another codec pack)
try to use Fobs4JMF
register in JMStudio IBMdecoder, jffmpeg
Tanks for any help
the device support many configuration UYVY 235x288 352x576 .... 720x576 but JMF offer only 1 video mode for this device.
here in jmf my capture device info:
