How to change brightness of video player in C#?

1 New Member
hi

im workin for last few days on possibility to modify brightness or contrast in my video player (avi, mpeg, wmv)
i was tryin with
- DirectX.AudioVi deoPlayer
- Direct Show and Video Mixing Renderer
- Windows Media Player Component

in every case im able to play, pouse, stop, mute video and so on. but i stuck with controlling of brightness.

in AVP i havent find anything to workout.
in DS i found DirectShowNet library and with its help i tried to use ProcAmp Control Processing. but i fall into two errors - first 80040273 (VFW_E_DDRAW_CA PS_NOT_SUITABLE ) happened becouse im using pivot monitor in vertical mode, so when i come back to horizontal - error gone. Second error 0x80040299 (VFW_E_VMR_NO_P ROCAMP_HW) showed me that my hardware doesnt support ProCamp - strange.
so i decided to try WMP component and again found nothing about brightness/contrast settings, well exactly i found that this component doesnt provide VideoSettings. there is something about IWmpVideoSettin gsCtrl interface but nobody knows how to find it. after another few hours of googling i found comertial component named "WMPEx" which provide wide functionallity of WMP, but it cost $1600 (lol), there is a free version of WMPEx but it only supports changing of hue.

and now i have no more ideas how to solve this problem.
please take a look at this. i hope that someone figured out it and found the solution.

regards kukoc

Question, can I see an event in Javascript that tells me a video starts playing using the <embed src="file.wmv>. I stream the video, but there is a wait time and wanted to pop up a message telling the user it is buffering until the video actually begins to play in the browser. Thanks for any help! JJ

Hello all, I have a Linksys WVC54GC network camera that I am trying to integrate into a website and to enable browsers other than IE to use. Linksys, in their ever-short-sighted ways, decided to make this device only compatible with IE. It requires IE and ActiveX. However, you can access the video stream directly with the following URL http://1.2.3.4/img/video.asf

So I tried to do my father a favor and convert his advertisements to .flv and place them on his website. With Flash being $600, I found an open-source .flv player and configured it. So today he called and stated it isn't working with IE. The script: <script type="text/javascript" src="http://www.fivestarsuzuki.com/ video/swfobject.js"></script> <script type="text/javascript"> <!--

I did a website for a friend's company where they wanted a 'downloads' section similar to standard file sharing you see all over the place. Everything works great except for video.

Since my pc is also my test environment, I try to open the same video from the test site and I get the standard 'Can't...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
