capturing a frame from video to image

[xEnOn]

Hi people, I am trying out Flix and I was hopping to do a video frame capture from video files. I need flix to capture one of the frames in the video and save it as an image file. these image files are going to be used as thumbnails.

it would be great if it could capture video frame image from any video formats but it will be alright too, if could only do this in FLV video files.

i looked into the sample files and i have no idea how i could do this. i am using PHP with flix. can anyone help on this?

thanks :)

Hey, here you can see documentation about your problem.
Note that fli engine only capture the first frame of video.

You can export an image (or multiple images) using the png export functionality in the latest version. It is not limited to the first frame anymore.

Does anyone have a sample code that exports multiple frames to PNG images?


Tks!

I found a sample code. Use the code bellow before the encode process


string flxPNG = "png exporter";
string pngDirectory = "C:\\TesteFLIX\\png\\";

IFlixPlgn flxJPG = flix.addFilter(flxPNG);
//Generate 4 PNG files
flxJPG.setParam(flix.FE2_PNGEX_AUTO_EXPORT_COUNT,4);
flxJPG.setParamAsStr(flix.FE2_PNGEX_OUTPUT_DIRECTORY,pngDirectory);
flxJPG.setParamAsStr(flix.FE2_PNGEX_FILENAME_PREFIX, inputFile);
flxJPG.setParam(flix.FE2_PNGEX_HEIGHT,84);
flxJPG.setParam(flix.FE2_PNGEX_WIDTH,117);

I'm not sure but the old jpg functionality may still be in the product, but it's limited to the first frame if it is. I don't mind extracting a png. In my conversion process, I convert the extracted image from png to jpg. It only takes a second to process. .NET has all the classes you need. If you are using another language, I'm sure something is available for you to convert. Note that most browsers these days DO support png, including mozilla, firefox, ie, opera, etc. However, png images are much bigger than jpg, so if file size and/or ultimate compatibility are issues, then just grab some code to do the conversion.
