I need to create an application that captures a video from a webcam. Later on I need to load the video and be able to navigate around in the video freely.
When I use the videocap-demo that comes with the Sources of DSPack, the captured video is encoded in H264. When I navigate around in that video, the picture becomes blurry, with wrong colors and you can't recognize the picture. (I tried with VLC and Windows media player)
...playing the video works, but after jumping to any position in the video, it looks like this...
How can I tell DSPack to capture the video e.g. in the old MJPEG-format?
(I tried with old videos from my camera. In MJpeg the navigation seems to work flawless)
Thanks in advance, R.

I currently use the vlc for unity (libvlcsharp) for a media player project.
It performs well but when I play the 360 video it automatically shows the center viewport of the panorama video due to the metadata.
Why does the VLC do things like this? And according to the forum, I cannot disable this feature?
I have been recording a video game series with this old Dazzle capture card. If you look at my video, you can see how the footage looks fuzzy.
I think it has something to do with my having to deinterlace it. I tried a couple different deinterlacing options, but the video just didn't look right.
The video's format is 1080p and I believe the game's native resolution is 480p. Can someone tell me how to fix this?

I have been trying to create a video template which uses alpha channel video overlayed on the mp4 videos and images.
This is how I need to create a video http://viewptch.ptchcdn.com/rendered/52b28a9f8d4f980f3a3f99c3_cb44bf2b/52b28a9f8d4f980f3a3f99c3_lrg_main_main.mov
For overlaying alpha video on another videos, I have used AVAnimator, I was succeeded for playing a preview using AVFoundation, AVSynchronizedLayer and AVAnimator.
When rendering video from composition, frames of alpha channel videos renders very slowly.
I need to create a video with alpha channel video on top of another video.
Can any one please suggest me what are the possible ways to render a video like http://viewptch.ptchcdn.com/rendered/52b28a9f8d4f980f3a3f99c3_cb44bf2b/52b28a9f8d4f980f3a3f99c3_lrg_main_main.mov ?
You mention that you have looked at AVAnimator, did you download the KittyBoom example project and try it out? The specifics of how it works are detailed in this post. One thing to note is that when you build and run on the device, you need to turn Debug mode off otherwise it will not execute quickly because a number of extra checks are done in debug mode. Also, you have to make sure to test on the actual device, the simulator is not a good measure of performance on a real device. Performance is a key problem with video that contains an alpha channel as iOS does not support video with an alpha channel by default.
I am trying to make a nice pretty video.
I have a AVI video from a GOPro video camera, and I hae some info I want to overlay on top of the video. Like Time, GPS, Speed, G-Force etc.
I got my raw data, and ActionScript coded it up into a Flash movie, but then worked out I have two issues.
Flash export to AVI is pretty crap, and basically does a screen capture.
The export to AVI cant be transparent or anything but spare/rectangle.
So, can anyone suggest a better way? Should I use something other than Flash to create my speedometer, that is more friendly for overlaying on a AVI?
This is the sort of thing I am trying to create.

I have a CSV of all my raw data, and am trying to find a way to overlay it and look as professional as that link above. I can make the dials in actionscript, but then exporting to AVI with a 'screen capture' type program, they look pretty crap. But on the other hand, inporting my HD video info Flash, and it becomes pretty crap quality, and still have the export issue at the end.
I'm not 100% clear on what you're trying to do.
If you mean that you want to put some info over a video using Flash, all you need to do is import your video onto the timeline on one layer and then place your information on a higher layer. If you want your video to play as a different shape, then you can simply apply a mask to the layer your video is sitting on.
If you throw in more directing information then I'll improve this answer for you :)
Is there any way to play mpg files in XNA? (I want to develop a game that a video stream has to play at background)
XNA has built-in video playback. A good place to get started using it might be Catalin's XNA 3.1 Video Sample.
One downside to XNA's built-in functionality is that it has limited format support (specifically WMV9). So you will need to convert your video to that format. Two options for encoding are Windows Movie Maker and Windows Media Encoder (which seems to have recently become Expression Encoder 4).
Once in that format, you can simply add it as content to your project. Then load it as a Video through the content manager, and use VideoPlayer to play it back, calling videoPlayer.GetTexture() to get a texture of the current video frame you can set on the device or pass to spriteBatch.Draw().
