[android-developers] Calculate percentage of a video file
Hello Sir, I am playing a video file , i want to calculate percentage of video file . using this code int current=video.getDuration(); int total= video.getCurrentPosition(); int per = (current/total)*100; This way is wrong behave please confirm me this is right or wrong. which is easiest way solve my issue. -- You received this message because you are subscribed to the Google Groups Android Developers group.

*Manually calculate the bitrate** *The basic bitrate formula is (*S*ize - (*A*udio x *L*ength )) / *L*ength = *V*ideo bitrate L = Lenght of the whole movie in seconds S = Size you like to use in KB (note 700 MB x 1024*°* = 716 800 KB) A = Audio bitrate in KB/s (note 224 kbit/s = 224 / 8*°* = 28 KB/s) V = Video bitrate in KB/s, to get kbit/s multiply with 8*°*. *°8 bit = 1 byte.* *°1024 = 1 kilo in the computer world.* Example 90 minutes video, L = 90 x 60 = 5 400 seconds 700 MB CD but be sure that if fits use a bit lower like 695 MB, S = 695 x 1024 = 711 680 KB Audio bitrate, A = 224 kbit/s / 8 = 28 KB/s (711 680 - (5400 x 28) ) / 5400 = 104 KB/s x 8*°* = 830 kbit/s.

You have too much to do this morning but still found a few minutes to troll, eh? Good you have your priorities straight, at least. Audio bitrate, A = 224 kbit/s / 8 = 28 KB/s (711 680 - (5400 x 28) ) / 5400 = 104 KB/s x 8*?* = 830 kbit/s. Again, you need to get your units straight That chore list isn't getting any shorter! One knows the length of the video file up front, be it in seconds or KB or whatever unit, The only tricky thing is to determine what fraction of that size/length has been consumed at a particular point in playback. The technique depends in part on how precise you need to be. If you're just showing a progress bar, or calculating to, say, the nearest 5%, you can probably get away with ignoring the wobble factors like CRC, perhaps with a correction applied every 100 MB or so to reduce cumulative error. If you need ppm resolution your calculations will need to be more precise. You can measure time or you can measure stream size. If you know the number of seconds of the entire video, and you have the current tickmark from the video, then Bob's your uncle. You can skip all that fooferol of bytes/second, yada yada, and just use the timestamp-to-duration ratio. If you cannot get at that data, you can use the system clock to approximate, but you'd have to factor out any pauses, fast-forward or whatnot. I'd venture that dealing with rewind, pause and fast-forward will cause you more trouble than the raw calculation of ratio completed. It all hinges on determination of your current position in the video. -- Lew -- You received this message because you are subscribed to the Google Groups Android Developers group.

Uppercase 'K' is a common mis-use, but that doesn't make it correct any more than mb is correct for MB. Next time you try to correct someone on units used in telecom, networking, etc., try not to do so with a senior network engineer.

Notice that the chart shows a *lowercase* 'k'. Thanks for proving my point.

MB/s ones have only recently turned up here. Thanks -- You received this message because you are subscribed to the Google Groups Android Developers group.
