Hi,
Comparing the video quality objectively is not very easy. So I'm thinking about comparing two mpeg4 videos by comparing the counts of received I-frames and P-frames.
But I think we should treat I and P frames differently.
Then my question is how different we should treat them? Is there any formula or scheme that can convert the received I and P frame count into the video quality measure?
Thanks,
Tejas
