HI,
thanx for the reply. yes, i do understand that
ooh323 has not got any codecs to grab-encode-decode
video, but has compatibility, in the sense that it has
channels that do suppot video.
The ffmpeg codec accepts the video from a grab device
and converts it into a yuv/mpg or any format needed
for encoding. Then on the other end, u need to convert
this to a "playable" file format, like yuv/rgb.
Now, can u tell me which wud be the best encoding.
shud the grab device encode the video to mpg format
and the decoder then decodes it from mog to yuv
format, that is viewable on the screen.
So, can u tell me which is the best way to encode,
like for audio we have pcm to ulaw and the ulaw to
pcm.
