Hi,
I am trying to evaluate the AVI processor for inclusion in my application.
I made a small sample project (VS 2010, c#)

And I keep getting a null reference error when I try to instantiate the aviwriter object.

System.NullReferenceException was unhandled
Message=Object reference not set to an instance of an object.
Source=Aurigma.GraphicsMill
StackTrace:
at Aurigma.GraphicsMill.Codecs.FormatWriter._Close()
at Aurigma.GraphicsMill.Codecs.FormatWriter.Dispose(Boolean disposing)
at Aurigma.GraphicsMill.Codecs.AviWriter.Dispose(Boolean disposing)
at Aurigma.GraphicsMill.SyncHandler.Finalize()
at Aurigma.GraphicsMill.Codecs.FormatWriter.{dtor}()
at Aurigma.GraphicsMill.Codecs.AviWriter..ctor()


Attached is my sample project.
It was designed to take a serieas of images (all ready created) and stitch them together into an AVI file

GraphicsMillCreateAviTest.rar (10kb) downloaded 22 time(s).

Hello,

Thank you for these files. I investigated the problem. AviWriter supports Format24bppRgb 24 and
Format32bppRgb pixel formats. Your PNG images are Format32bppArgb. You should converted them to one of the support formats before adding them to avi file.

Hi Dmitry,
I'm not even getting to the stage of being able to add the files to the avi writer.
It is erroring out on this line of code

_aviWriter = new Aurigma.GraphicsMill.Codecs.AviWriter();

Hi Paul,

I investigated this problem. It occurs if trial license key has been expired or has not been set at all. I generated trial key for 30 days - please read PM. Please specify it through License Key Registration Wizard which you can find in the folder where GM was installed. Sorry for the inconvenience.

Hi Dmitry,
Ok I got past that stage now I'm having some different issues.
Using XVidMpeg4 I kept getting a

Aurigma.GraphicsMill.Codecs.MediaProviderException was unhandled
Message=Cannot set video stream format.

My source images were 1102x517, but I then changed the aviwriter to specifically create it at 1280x720 and resize the frames and it worked.
When I recreated my source images at 1644x852 it worked as well without me having to specify another size.

Does this mean that XVid recordings can ONLY be created at specific sizes? Or is this kind of a 'driver/operating system' thing becuase I have seen them created on other cmputers here in the office without issue (using on of 3 different avi creators)
Turns out none of the 3 work on my computer though. So i'm wondering if XVid has some graphics card specific limitations?
I have a good graphics card (ATI Mobility Radeon HD 5830), and I know one of the computers XVid is working on is a really crappy card.

This was one of the reasons I was trying out GraphicsMill, was to see if the issues with recording to xvid on my machine could be gotten around. Certain clients of the existings system have problems as well, while others don't.

I was able to get MSVideo1 to record an avi without a problem, except that the quality is very sub-par, especially compared to xvid.

thanks
paul

Hello Paul,

Actually Avi Processor Add-on is based on obsolete library VfW (Video for Windows). Unfortunately many modern codec do not support it. I assume that the machines where you get good results, have codec supporting VFW. Please check it and try another codec.

Hi Dimitry.
I went ahead and purchasd the Graphics Mill component.
Now I am getting a different kind of error.

A first chance exception of type 'Aurigma.GraphicsMill.UnexpectedException' occurred in Aurigma.GraphicsMill.dll
'GraphicsMillCreateAviTest.vshost.exe' (Managed (v4.0.30319)): Loaded 'C:\Windows\Microsoft.Net\assembly\GAC_MSIL\System.Configuration\v4.0_4.0.0.0__b03f5f7f11d50a3a\System.Configuration.dll', Skipped loading symbols. Module is optimized and the debugger option 'Just My Code' is enabled.

at GraphicsMillCreateAviTest.Form1.CreateAvi() in D:\projects\prototype\GraphicsMillCreateAviTest\GraphicsMillCreateAviTest\Form1.cs:line 74



Using the attached project and these recording files
(http://www.aras360.com/customer360.com/recordings.rar) (~250mb)

It is 255 frames of pngs at 1280x720.
It gets to about frame 243 and then errors out (and errors for the rest of the frames as well)
Some smaller sets of frames I was able to do fine.
In further testing I found it seems to be memory-related.
Watching in my Task-Manager the memory being used steadly climbs and when it hits roughly 1.5 GB is when it crashes.

Hi Paul,

According to the error stack trace and your description you have "Unable to commit memory" problem.
32 bit applications can access only 2 GB of RAM. Sometimes, this memory is not enough to handle loaded images and run other applications. Thus you get the “Unable to commit memory” error. To resolve the problem, you need to use 64-bit system with 64-bit Graphics Mill.

Hi Dimitry,
so that being said I can't use Graphics Mill to create an avi as 1280x720 that is longer than roughly 10 seconds?
Seems to me that the memory usage is bloating too fast.
the amount of memory that increases when each frame is added is more then 2x what the image is (assuming an um-compressed bmp) and never gets cleared.
Now I know other 32-bit programs are able to create avi's much large than this without the memory issue. Though none of them have an SDK available to use.

Is there something I need to do differently in creating the avi?

Here is my main worker function
Code:

    void CreateAvi()
        {
            List<string> files = GetFiles();

            _aviWriter = new Aurigma.GraphicsMill.Codecs.AviWriter();

            _aviWriter.CompressorHandler = Aurigma.GraphicsMill.Codecs.AviCompressor.XvidMpeg4;

            _aviWriter.ResizeFrame = false;

            _aviWriter.FramesPerSecond = 30;
            _aviWriter.BytesPerSecond = 128;
            _aviWriter.KeyFrameRate = 160;

          
            _aviWriter.Open(_aviFile);
            for (int i = 0; i < files.Count; i++)
            {
                try
                {
                    Aurigma.GraphicsMill.Codecs.AviFrame frame = new Aurigma.GraphicsMill.Codecs.AviFrame(new Aurigma.GraphicsMill.Bitmap(files[i]));
                    _aviWriter.AddFrame(frame);
                }
                catch (Exception ex)
                {
                    System.Diagnostics.Debug.WriteLine(ex.ToString());
                }
                
            }
            _aviWriter.Close();

        }


I've tried closing,disposing the aviwrite every 50 frames, with the intent of re-opening to append more frames. but the memory doesn't clear up when I close and dispose the aviwriter.

Any thoughts on this?

thanks
Paul

Hi Dmitry,
Ok I might have found a method that works.more testing required but it appears I need to explictly dipose of each and every frame after it is added to the avi writer
Code:
          for (int i = 0; i < files.Count; i++)
            {
                try
                {
                    Aurigma.GraphicsMill.Bitmap bmp = new Aurigma.GraphicsMill.Bitmap(files[i]);
                    Aurigma.GraphicsMill.Codecs.AviFrame frame = new Aurigma.GraphicsMill.Codecs.AviFrame(bmp);
                    _aviWriter.AddFrame(frame);
                    frame.Dispose();
                    bmp.Dispose();
                }
                catch (Exception ex)
                {
                    System.Diagnostics.Debug.WriteLine(ex.ToString());
                }
                
            }


this reduces the memory footprint substantially.

cheers
paul
