now, run the program and enter your frame number in the first edit1.text.

in button1 onClick event, enter this: edit2.text := frameNo2timecode(strToint(edit1.text), 29.970).

put two Tedit's and one Tbutton control on your form1.

so just feed it a frame number and the function will return the timecode in string format.

It computes the timecode based on the frame rate of your video source (ie 29.970 interlace or progressive, and 23.976 for 24p film).

but just so you know, i like my numbers formated for spacing purposes, so i padded to 2-digits, this way there is not shriking back and forth as numbers progress past 59. To my knowledge the routine works flawless.

the following links did help me out some though (but due to c/c++/c# i could not translate as easily to delphi) so most of the final answer were based on lots of trial and error:

This way, with a bit of fine tuning, you should be able to get capture rates are are within a +/-1ms tolerance of the actual video FPS.Īs promised, here is the code i came up with based on some google searches and working them out in delphi. I've generally set the timer to call a single procedure recursively, until it's flagged to stop. The nice thing about the Multimedia Timers is that they let you use it as a 'one shot', where each interval can have a different delay period. HowLongTimerShouldWait := LengthOfASingleFrame - TimeSpentCapturingPreviousFrame Then, when you call "timesetevent" in a multimedia timer, subtract the amount of time the capture took from the overall time of a single frame, and use that as your "uDelay" value. What I would try is using the Performance Timer (queryperformancetimer, as you've already mentioned) to time your "CaptureWindow" procedure. The "Multimedia Timers" offer good resolution (down to 1ms on most machines), and I've found them to be reliable.

Assuming that the software playing the video is also well timed, you should be able to get a smooth capture.

Here is the complete routine (along with some remarked-out experimental code) for this: To help simiplfy the process, i snipped a lot of code of the original project to only feature the screen capturing. timer1 control - setting interval to 34 is not exact, it duplicates or misses frames during screen capture.i've been reading a lot about the following items below but they are all over my head though i did make many attempts at it: I'm not sure how to implement the necessary routines into mine, let alone where.

So i need to be able to configure for both, somehow.Ĭurrently, I can screen capture from tv cards and software video players like, vlc, ffplay, mplayer, virtualdub, etc. i also need this with respect to syncing the captures to the framerate of the sofware player playing the video, otherwise i get a lot of duplicate or missed frames. basically i want to have the timecode and videos framerate of a current screen capture session showing in my app, in the statusbar or label. I have searched google pretty thorough but am not finding the answers to my delima.
