Commented Issue: AviFormat Enhancements and Fixes in progress

BrhineScot — Wed, 15 Jul 2009 23:15:29 GMT

I have been working on the AviFormat plugin. It looks like it wasn't really finished but it's a very good start and I will continue to enhance it. Thanks to Brian and whomever else worked on it.

Changes made so far:
- Added Frames Per Second (FPS) selection to context menu.
- Added plugin to Options page, allow change FPS and extension.
- Replaced Windows.Forms.Timer with System.Timers.Timer for better FPS resolution
- Fixed issue where main cropper form didn't correctly show Stopped/Recording status (required change to Cropper core)
- Fixed issue with timing which caused errors because AVI library isn't thread-safe.

Changes being considered:
- Quality selection, I'd like to see higher quality AVIs.
- Codec selection: CVID (Cinepak), MJPG, others? This isn't my field of expertise but I'll do what I can.
- Need to accommodate unexpected terminations. The AVI library is unmanaged code that uses an internal reference counter. This isn't cleaned up if a developer has to crash their testing or if an end-user brutally terminates Cropper. That could leave things in a weird state until reboot.

Proposals for other enhancements are welcome.

Expect a new release by 8/2009.

Thanks for the work Tony. I always thought the idea of video capture was an interesting one. I never considered when I originally wrote Cropper. Glad to see it getting more love.

Commented Issue: AviFormat playback speed

TonyGravagno — Mon, 06 Jul 2009 06:05:46 GMT

Cropper v1.9.1.89
Record a video and then play it back. The speed is way too fast.
Emailed author to see if he knows how to make it play in "real time". Will make change if I get a response, or try to fix it myself.
Also trying to figure out how to get AVI file to 10fps. This is hardcoded in the code but changing the value doesn't result in a file with a different fps.
Comments: ** Comment from web user: TonyGravagno **

This issue has been resolved. I'm trying to get Developer access to post this and other updates in a new release.

Corinna John (coco) suggested that the thread that captures images should not be the same thread responsible for inserting images into the AVI. This is correct. Now with separate timers managing the enqueuing and dequeuing of images I get a good 10FPS. The timing doesn't seem to be 100 perfect so I'm going to continue testing and will also test with higher FPS rates.

Commented Issue: [SendToTinyPic] Regex failed to match on proper result.

Cheeso — Thu, 02 Jul 2009 17:56:14 GMT

Thought I'd try the SendToTinyPic Plug-in. Downloaded the Cropper Plugins, and put the Cropper.SendToTinyPic.dll file in the plugins directory. I open up Cropper, and I now have a TinyPic Hosted Image under Output. I select it, and adjust the cropper frame thingy. But then when I double click the frame to do the capture, I get a message box which says:

Regex failed to match on proper result. Upload this file manually:
X:\Path\To\Cropper Captures\CropperCapture[1].png

What does that mean? Have I missed something? Or does it just not work?
Comments: ** Comment from web user: Cheeso **

I had the same error. Apparenly it just doesn't work. I produced a patch for the Send To Tiny Pic plugin. With this patch, the plugin now works for me.

I'm not a contributor to this project so I cannot update the source, but I uploaded it as a patch. Anyone can download and use it.
To use it, you'll have to re-build the SendtoTinyPic.dll plugin assembly, stop cropper, and then copy the new SendToTinyPic.dll plugin to the cropper.Plugins directory.

Find it at http://cropperplugins.codeplex.com/SourceControl/PatchList.aspx - it's # 3236. (Sorry, no direct link)

Created Issue: AviFormat file format has errors

TonyGravagno — Mon, 22 Jun 2009 18:05:10 GMT

Freeware AviMaster reports files have "Spurious Data after RIFF Chunk".
I'm looking into that as well as other details of the file format.

It would be nice to know who has experience with AVI file internals so that we can discuss details here. I have questions about Handlers, some of the other StreamHeader values, quality, etc. The basic code seems to have been taken from sample code created by Corinne John but to make this work well it will need many small changes.

Commented Issue: AviFormat playback speed

TonyGravagno — Mon, 22 Jun 2009 17:55:26 GMT

I've replaced the timer for better resolution. The playback time is still too fast. I'm trying to get a balance between the Rate and Scale using the following:
strhdr.dwScale = (int) ( 1000000 / frameRate ); // duration of each video frame in ms
strhdr.dwRate = 1000000; // rate/scale=FPS

Corinne - In your codeproject article you said this:
========
Do you find your video too slow, or too fast? Tell the player application to play more/less frames per second:

Avi.AVISTREAMINFO info = editableStream.StreamInfo;
info.dwRate = (int)(numFrameRate.Value * 10000);
info.dwScale = 10000;
editableStream.SetInfo(info);
========
But all that does is scale up both the dwScale and dwRate. I don't understand how that code would help a video player to adjust the playback rate.

On the following page you have a lot more code built around the rate/scale pair:
http://technica-svn.cvsdude.com/asciiFx/trunk/asciiFx.Engine/Media/VideoStream.cs
In the VideoStream constructor:
this.frameRate = (float)streamInfo.dwRate / (float)streamInfo.dwScale;
and then there's this interesting code:

private void GetRateAndScale(ref double frameRate, ref int scale) {
scale = 1;
while (frameRate != (long)frameRate) {
frameRate = frameRate * 10;
scale *= 10;
}
}

That gets called from CreateStreamWithoutFormat() as follows:
int scale = 1;
double rate = frameRate;
GetRateAndScale(ref rate, ref scale);
but then the scale is still hardcoded to 1:
strhdr.dwScale = 1;
strhdr.dwRate = (int)rate; // Frames per Second

I believe the Scale should be equal to the duration of each video frame in ms, so if the video was recorded with an interval of 100ms (=10FPS) then scale should also be 100, and rate should be multiplied to achieve the right balance.

Using AviMaster (freeware) I can look at the AVI headers and see the scale, rate, and FPS are correct in files I create, but the timing is still a bit off. Could you provide some insight into how you've stabilized playback time in your own code?

I'm starting to wonder if this has to do with the CVID codec. I'm experimenting with MJPG. Comments on this are welcome as well.

Thanks!

Yes, it makes sense that we won't get better than 10fps if the timer is only triggering 10 times per second.
So it seems you're saying a better timer will allow for resolution of 30fps _and_ the fps value in AddVideoStream should correspond to the interval.
I'll give that a try, and I'll see if I can allow the user to change FPS via the Options settings while I'm in there.
Thanks!

MSDN says:
"The Windows Forms Timer component is single-threaded, and is limited to an accuracy of 55 milliseconds. If you require a multithreaded timer with greater accuracy, use the Timer class in the System.Timers namespace."
http://msdn.microsoft.com/en-us/library/system.windows.forms.timer.aspx

I suggest you try the better timer class.

coco — Tue, 16 Jun 2009 20:14:42 GMT

In AviFormat.persistableOutput_ImageCaptured the frame rate is set to 10 fps:
stream = aviManager.AddVideoStream(true, 10, (Bitmap) e.FullSizeImage);

In AviFormat.Connect the record interval is set to 1/10 seconds per frame:
recordTimer.Interval = 100;

So, the timer should records 10 frames per second - in theory. I guess the timer is not that exact, especially when the computer is running a lot of processes. Actually, the event is called less than 10 times per seconds, recording much too few frames.

Hello, I have the exact same problem (using Vista x64). I would really like this feature to work. Why was this issue closed?

CREATED ISSUE: [AnimatedGIF] sound

kotecky — Wed, 28 May 2008 08:38:13 GMT

The sound produced when starting and ending the capture is a good idea. Nonetheless, it should be configurable. For example the user should have the option to turn it off or at least to choose the level. The sound such as it is now is quite annoying and unusable for people who work in a library etc.

CREATED ISSUE: BUG : TFS Create Work Item - Fails

PJTewkesbury — Sat, 24 May 2008 12:03:08 GMT

I have a VPN link to a TFS Server. Visual Studio works fine, but Cropper Adding TFS Create Work item fails with 'You are not authenticated for TFS Server' After some digging, it turns out that if you supply the logon credentials when you connect to TFS Server, all is OK.

Can you add to the TFS Create WorkItem settings, UserName,Domain & ask for password, or use local connection to get over this problem.

NetworkCredential newNetworkCredential = new NetworkCredential(@"<UserID>", "<Password>", "<Domain>");
TFS = new TeamFoundationServer(settings.TeamServer, newNetworkCredential);
TFS.EnsureAuthenticated();

Thanks.
