I'm recording from a webcam. The camera looks great in PhotoBooth. However, when I preview it in my program with a QTCaptureView, or record it to a file, it is very, very slow. The reason is that QuickTime is giving me the maximum possible resolution of 1600x1200. How can I force a more reasonable size for both my QTCaptureView and my re...
Hi guys, I am working on a site which would allow users to upload a video and my site would encode into 3 formats, wmv, iPod and zune. Are there any 3rd party tools/API's that can be used to do this? I am not sure how sites like http://channel9.msdn.com/ , http://www.hanselman.com/blog/ have got this. ...
I'd like to convert mp3's to lower bitrates, as well as possibly convert video to mp3 using Perl. I looked at the ffmpeg module but it doesn't appear that it supports converting files, the only example I saw was grabbing pictures out of a video stream. Is there a way to do this in Perl with out using system() to call ffmpeg? ...
Hi guys, I'm working on a flash site with lots of video-based section-to-section transitions. The transition videos themselves are only a few seconds long but are fairly weighty (~700kb) as they're very high-resolution; given the number of sections and section-to-section transition combinations (and therefore videos), preloading all of...
Do you know how to programatically obtain a list of video codecs installed on computer, from windows forms ? Thank you. ...
Hi guys, I'm building a flash site (as3) with large videos that act as transitions from section to section. The videos don't scale; in order to accommodate users with large monitors, we're planning on playing back HD video and only showing users the center of the frame (depending on their screen size). That is, there will be a central...
This is related to my another question Here I'd like to ask if it is in theory (according to video file formats and codecs, etc) possible to have such scenario: 1) Client on iPhone has a reference to video in flv format. It sends http request to converting "proxy" like http://convproxy.com?source=url_of_original_video.flv by just click...
Is it possible using the iPhone SDK to grab a frame from a video in iPhone and save it or use it in any way in the application? Does the SDK give any control over the video other than play/stop or maybe access to the binary data of the video? Also is it possible to know the time at which the user stopped watching the video (i know in SD...
Hello everyone, I am looking for a network camera which I could program against the following functions, I can plug-in the camera into network cable, then it could work to capture video independently, no need to plug-in into a computer to make it work; I can remotely control the camera, e.g. control its start/stop/direction; I can...

Is there an easy way to use DirectX in Java? In particular, DirectX's video APIs. I know that C# might be a more natural choice, but I have my devious reasons for wanting to do something so perverse. ...
I would like to record the user's interaction in my Java Applet as a video to send (potentially stream) to my server with the intention of uploading to Youtube (or similar). A high frame-rate is not required (a couple frames per second is sufficient). Minimizing the bandwidth used is preferred, so sending jpeg snapshots to the server a...
Hi, Does anyone have a good suggestion on how to do video recording? We have a camera that can record and then stream live video to a server. So this means we can have 1000's of cameras sending data 24X7 for recording. We will store data for over 7 / 14 / 30 days depending on the package. Per day if a camera is sending data to the se...
I'm writing a PHP script that converts uploaded video files to FLV on the fly, but I only want it to run that part of the script if the user has FFMPEG installed on the server. Would there be a way to detect this ahead of time? Could I perhaps run an FFMPEG command and test whether it comes back "command not found?" ...
Hi, I want to play H.264 video streamed from network. To play video iphone provides the media player API. Does anyone one aware of any documented or undocumented API for decoding and playing single video frame? ...
Hi I'm trying to modify a web page so that it loads faster. Since I have some videos embeded (blip.tv but can change it to youtube if it helps) I was wondering if you could load an image where the video should be and on click replace the image with the video and start playing (without reloading the whole page). I think I've seen this be...
I'm wondering if it's possible at all to sort of record/capture the state of an swf movie over a period of time and save it all down as jpgs to the server? AS3 has the new com.adobe.images.JPGEncoder class that seems to do the job, but can I capture a sequence? The hope would be that I could put it back together as a video or animation...
Our website lets people add videos by submitting a URL - usually one from YouTube or Vimeo. I'd like to show thumbnails, when giving people a list of videos. YouTube make this easy for me - just slap "1.jpg" on the end of the URL, and you've got your image. Vimeo seem to want me to make a HTTP request, and extract the thumbnail URL fro...
Hello everyone, I am using the following code to leverage Windows Media Encoder to record screen. I am using Windows Vista, screen resolution 1024 × 768， 32-bit. My issue is, the video could be recorded successfully, but when I playback the recorded video, the quality of video is not very good -- e.g. characters are very obscure. I am w...
