Calculating FPS

Okay, so I am not sure whether I am just googling badly or if I'm not reading what I find well enough, but I have been searching for a way to calculate fps in a similar way to how Fraps does or the Steam fps counter from within my wpf Application. So far
I have only been able to produce the refresh rate of my monitor using the code below. Any help would be greatly appreciated!
void fps_Tick(object sender, EventArgs e)
//fps.Content = CalculateFrameRate();
if (System.Environment.TickCount - lastTick >= 1000)
lastFrameRate = frameRate;
fps.Content = lastFrameRate.ToString();
frameRate = 0;
lastTick = System.Environment.TickCount;
frameRate++;
Thank You,
Jesse

Hello Jesse,
I want to know some more details from you, what is the frame in your post? Do you want to know system fps or your application fps? How you draw those frames?
Best regards,

  • Timed Loop in Producer/Consumer Loop

    Hello!
    I have a producer/consumer loop LabVIEW program setup to allow me to properly capture images that are quite large (8MP) at approximately 14 frames per second (FPS). The program works great when the consumer loop is a 'while loop' (records at 14fps no problem), but I wanted to make it into a timed loop, so that I may vary the FPS as required. An oddity arises when I do this. Anywhere below 12fps, the loop works fine and the data is recorded properly. However, when I bump it up to 13fps, the consumer calculated FPS goes haywire and starts jumping between ~9 and ~13fps (data processing gets bogged?). When I set the required FPS to 14, the loop executes at a steady 7FPS maximum. Is there something I can do to rectify this situation?
    I have attached my .VI
    Thanks in advance!

    Palanski,
    Are you using LabVIEW Real-Time? Timed loops in a windows OS don't really increase determinism more than a while loop with a wait until next multiple timer. Before you changed the producer consumer loop to include a while loop was the programming running correctly? You may also want to vuse the VI analyizer to see how long things are taking to run. I would leave the producer consumer loop in the traditional set up and change the FPS by controlling the wait timer, after benchmarking your code this should be done the same way as you have it for the timed loop

  • Filters for video and FPS on mobile devices

    Hi,
    I tried to apply a filter to a video on mobile phones and had a strange effect:
    When I apply the filter to a 24 FPS source video the resulting frame-rate after applying the filter drops to about 7 FPS. But if I use a 8 FPS source video the frame-rate is even lower at about 3-4 FPS. I expected an higher, or at least equal resulting framer-rate with the 8 FPS source video. What's the reason for this behavior?
    I use the Flash Player 10.1 for Android 2.2 and the Google Nexus One.
    Greetings
    Stefan

    I know that there is no "calculation" of the Framerate! You do not understand my problem: if the client is capable to calculate 7 frames=images per second using the filter, why it only calculates 4 images per second if I take exaclty the same source video stream and just reduce the delivered framerate to the device of it from 24 to 8.
    So with regards to your anwser: the highest rate the client can handle is about 7 frame per second when the filter is applied.
    And just for the understanding: I have a video object who displays the video stream from a streaming server. On this video object i apply the filter one time and afterwards each frame is processed applying this filter. So there is no alternately applying and removing of filters.

  • Stream 2 x 120 fps cameras to disk ... HDD can't keep up?

    So I have two Basler firewire cameras.  Each camera has its own firewire-B card.  And I I wrote some LabVIEW software that can grab frames at 120 fps per camera. 
    But I am unable to stream to disk quickly enough to keep up with the frame grab.  Even if I use a producer-consumer architecture, my buffers end up overflowing.  Because I am logging from two cameras simultaneously, I am essentially streaming 240 fps to disk, and each image is color and 640x480.
    Question:  any reccomendations on how to get around this?  I am curious if a new and fast PC with a super-fast HDD will solve the problem.  Or maybe even a SSD drive?

    It all depends on the data rate you have to stream. Different storages have different performance. Benchmarks are the key to get a feeling if a storage type (HDD, SSD, RAID) is sufficient to handle the given data rate. This white paper has some sample benchmarks included which can give you some figures.
    Let's make a small calculation on your figures:
    640 * 480 (Resolution) * 2 (32 bit color depth) * 240 (fps) = 147456000 B/s. This is round about 147 MB/s. Pure data without any additional information.
    So you can see that even SSD will most probable be not sufficient (read something about 70-80MB/s for SSD writing), so you will have to use RAID.
    hope this helps,
    Norbert
    EDIT: The transferrates for SSD is very different. Maybe, this chart helps a bit, even though it does not state MB/s....

  • Time calculation in setInterval

    my code is
    var myInterval = setInterval(wait, 6000);
    function wait() {
    _root.img_mc.play();
    and my clip "_root.img_mc" changes every 60 frames (frame
    rate is 30 fps). When i type the above code i expect the clip
    "_root.img_mc" should change after 6 sec., but it is changing after
    3 to 4 sec.
    That means i am somehow laking in calculations or unable to
    understand the function. Plz help

    if your _root.img_mc isn't stopped at any time, it will, once
    it started playing replay every 2 second (60 frames with 30 frames
    a second.) If your animation is too stressful for the CPU, it might
    be more.
    So take car to stop your clip after it has been running and
    use something like gotoAndPlay(1) (or 2) in your wit
    function.

  • What's the correct workflow for high FPS footage motion blur?

    Situation is the following:
    I have a few 600fps recordings I want to put together with heavy editing.
    Things I want to do (not in order):
    Change the velocity heavily up and down, from 300% to 10% and back withing seconds.
    Basic VFX, heightmap, masking, light flashes and so on.
    3D tracking and effects, particles and text in 3D space
    Color Correction
    Good motion blur
    Overlays
    Now, my question is at which point I apply the motion blur. I'd like to start in Sony Vegas for the velocity and then move to After Effects.
    But Sony Vegas is capable to export at max 120fps. Will the motion blur result be worse/different with minro FPS footage?
    In Sony Vegas for example, the resample feature is pretty useless/bad unless you go over 120fps.
    But obviously I can't start by importing my footage into AE and firstly add motion blur. By my understanding I have to do all FX and color correction before adding motion blur, and until then the footage has to stay 600fps. Is this correct?
    Thanks in advance.

    and until then the footage has to stay 600fps. Is this correct?
    No. Motion blur is calculated from frame to frame at the actual playback speed. Anything else would look fake, anyway, though of course you may already ned to/ want to add some motion blur to some elements halfway through just to from the precision of higher framerates. Smoother curves and all that. So ultimately in which order you do it is till a matter of what gives you the best result, not so much a fixed "correct" order.

  • SG is slowing down the FPS to 24fps if the original file has more FPS

    I put a MOV file from my GoPro Hero 3 into SG, The file has 50fps but SG plays it in 24fps so it is slowmotion
    where do i set the program to play the file in the original fps?

    Now that the cache is large enough the problem is that it has to trigger all of the dense calculations when it is returning the blocks. You have said they are complex calculations so it is taking time. What version are you on? It seems to me in one of the more recent versions there isa cfg setting to not calculate values not returned. (I don't have the tech reference available right now,and don't remember what it is called)

  • Reducing fps raising the kbps?!

    hi all,
    i'm using the fmlecmd.exe file also fmle 3.2 windows version (tried 3.1 too) to publish my video from a windows 7 os.
    the video source is a MediaLooks video mixer, which use a Panasonic DV camera as a source (camera -> mixer -> fmle)
    currently the mixer output the video at 25 fps, but in the fmle there are more choices.
    now setting the fmle to 150kbps at 25 fps creates (measured by netlimier or perfmon) a 20000 Bps stream (more or less 150kbps)
    setting the fmle to 150kbps at 15 fps creates a 32 kBps stream (more or less 250kbps)
    setting the fmle to 150kbps at 30 fps or higher make the stream just a little lower at 19.5 kBps.
    setting the mixer to output the video at 15 fps will make the fmle :
    set at 150kbps and 15 fps to publish at 20000 Bps (~155kbps)
    set at 150kbps and 25 fps to bpush at 19,500 Bps (~150kbps)
    set at 150kbps and 10 fps to publish at 28000 Bps (~215kbps)
    in simple calculation when the fps is lower the published video uses a <setted birate> / <target fps> * <origin fps> instead of (in my understanding)  using the same bitrate and sending less frames (so the quality will be better)
    from my understanding thats an unexpected result.
    i read here in some other discussion that the fmle doesn't really know to change the source (which is the mixer here) fps, is that true? even so why is the bitrate going up when lowering the fps?
    Any help is appreciated!

    I would recommend going to 15 if you are going to play with frame rate.
    If you want to know how data rate effects the size
    double-click the setting for your movie
    look at the inspector
    Under the summary tab compressor show you how big the file size will be at _ data rate etc.
    Changing the data rate will be reflected here.
    When a client doesn't want a file over 15mb I use this tool to know and understand how data rate and other settings effect the overall file. This works for h.264 but may not be the same for every setting.

  • FPS Issue

    I have created a 12fps swf (calculator.swf) that simply has
    six independent numbers that change on each frame - think of a
    calculator gone crazy !! I've then created a another swf at 1fps
    and use the playmovie function to play the calculator.swf. The
    obvious problem is that I lose the speed at which the numbers
    change.
    Is there anyway to run a 12fps swf inside of a 1fps swf ? If
    not, how can I simply code a set of numbers that change fast
    independently of each other ?
    Many Thanks in advance - this has been driving me insane !!
    Typical novice eh ??

    You can mimick the 1 fps with a 12fps SWF. Simply make each
    keyframe last for 12 frames, and you effectively have a 1fps
    animation. That way, you aren't dealing with multiple
    framerates.

  • Tax Calculation of free goods

    Hi
    We have a requirement where the client wants only VAT to be posted in GL accounts and not the price.For this I tried free goods condition type R100 with AltCBV 28.But the VAT value is also coming zero. I want the VAT to be calculated on Pricing condition and then give 100% discount.
    Apart from this I also tried to make pricing condition statistical and calculate VAT on it but then also system gives zero value for VAT.
    Also wondering if the scenario can be addressed with Free of Change Dellivery.

    Hi
    Normally in scenario where you are dealing with samples , there are cases you have to charge only TAXES / EXCISE part.
    Here my SUGGESTION is you can handle this through a simple sales order process, where you have to configure a new pricing procedure.
    1. Create a new document type to handle samples.
    2. Create a New pricing procedure where you can keep the basic price condtion as Statistical and rest all same as wht is is there your main pricing procedure. Just juggle with the TO-FROM to capture the TAX part in the total.
    3. Doc pricing procedure will help you to pick the new Pricing procedure
    4. Now Process this as a normal sales order
    5. This new document type will help you to have a proper reporting.
    The only constraint here is USER has to punch a fresh order seperately for such scenario. He cannot give a free good in the same sales order which is used as standard.
    The other way is you can configure a FREE GOOD Determination procedure as suggested  where you need to then have your Single pricing procedure accomodating the same scenario.
    Thanks

    You need to write a compound logical statement to evaluate all of the values and that statement needs to evaluate to true or false.
    Do you know how to write JavaScript?
    Do you know how to enter JavaScript calculations into a form field?
    For custom calculation of the text field I could write something like:
    // define an array of the field names to check
    var aNames = new Array("Text1", "Text2", "Text3", "Text4",
    "Text5", "Text6", "Text7", "Text8",
    "Text9", "Text10", "Text11", "Text12",
    "Text13", "Text14", "Text15", "Text16");
    // define a logical variable that is true if any field has a value of 1 - default is false or no field has a value of 1
    var bMatch = false;
    // value for text field
    var TextValue = 0;
    // logical value of field being equal to 1 test
    var FieldIs1 = false;
    // loop through all the fields and test the fields value
    for(i = 0; i < aNames.length; i++) {
    // logically OR the result of field i value equal to true with bMatch
    // get the value of field
    TextValue = this.getField( aNames[i] ).value;
    // test the value of the field
    FieldIs1 = Number(TextValue) == 1
    // logically OR the 2 values
    bMatch = FieldIs1 | bMatch;
    } // end field processing
    // set the field value
    if(bMatch == true) {
    event.value = "Y";
    } else {
    event.value = "N";
    You will need to change the field names to match your fields. You can add more field name or remove field names as needed and the script will adjust for the number of field names.

  • If statement in calculated batch characteristic (dependencies)

    I have a little problem with calculating a certain batch characteristic.
    The situation is the following:
    I have batch char A, batch char B and batch char C. Batch char C is the result of the sommation of char A and B. The problem I have now is that batch char C only should be calculated when batch char A and B are different from 0.
    I have a custom build interface that imports QM data to the batch chars. Default, all my batch chars are set to 0 so if I just say $self.charC = $self.charA + $self.charB, I always get a value.
    Is it possible to some sort of IF statement to check if the value is different from 0?

  • Pension not calculated when EE is hired mid-month

    Hi All
    Please suggest for the following....
    When an Employee is hired in the middle of the month, the system doesn't calculate Pension Contribution.
    Like if an EE is hired on 10th April. The system will calculate all payments & deductions, but it is not calculating the Pension Contributions.
    I am maintaining IT 169, 171 for Pension Contribution.
    The problem I found behind this is.....(WIth the help of an ABAPer)
    -: System checks the Payroll Period Start Date with the Org. Assignment start date. When it doesnu2019t match, the system does not calculate the Pension Contribution.
    For the time being I solved this through the following action -: In debugging, I canceled this condition (skipped this check). Then it calculated the Pension Contribution.
    But, this is not the right solution for achieving that as we are changing standard SAP coding.
    Please suggest any solution for the same.
    Thanks & Regards

  • Mid-Month Calculations

    I am bringing a fixed asset system online in SAP and during the legacy conversion it was realized that the test system is not calculating the depreciation using a mid month convention.  That being said looking at the configuration the company code was setup in 2005 and is in production and is productive (since 2005).  So it appears that this setting is global and SAP will not allow me to change these settings to allow mid month calculations.  Is this correct? anyone ran across the same issue.
