Test: 1finger.avi
Video Time : 14 sec video
No of Frames : 99
Now if it is true that the video is having 30 fps (frames per sec) when converted to uncompressed AVI then:
No of frames should be = 30 fps * 14 sec = 420 frames but actually it is 99 frames stacked into the program stack.
I think the frames per second is not 30 or may be I am missing something.
Correct me if I am wrong in calculation. We need to figure it out before we give the XML file to signal team and this would help Fan "what to put in time attribute in each event element". Right now she is printing frame no.
We need to come up with some calculations so that number of frames stacked into the program and fps make sense to produce some values to put in time attribute in each event element of any xml file.
I wont worry about picking up time from video. That is a long term goal and Fan is putting the the time when video is processed and some what make sense. But if we can not relate No of frames produced with video length then the signal team wont be able to analyze our XML file to produce anything meaningful and findings would be meaning less.
Lets work on it. Looking forward to the "video sub team(Peter/Fan)"-------->
The tested frame was actually 7fps and so 7 X 14 =98 was OK.
