an error-handling section. The full syntax of the try..catch statement is: try { ... statements ... } catch(err_msg) { ... statements ... } The err_msg string in the catch block megui couldn't run updater contains the text generated by AviSynth when the error inside the try block was encountered. This text is the same that would appear in the familiar MessageBox that shows up when a fatal script error occurs. You can query the text (it is a normal string variable) to find specific substrings inside that indicate the error that has been encountered. avisynthwrapper.dll download This is a technique that can produce many useful results (for an example, see here). Other control structures (in the broad sense) In the broad sense, there are many elements in AviSynth Syntax that although not control structures by themselves, together allow the creation of language constructs equivalent to a control structure. Those constructs in turn allow the performance of complex programming tasks. The elements under consideration are the following: The Eval() statement that allows execution of arbitrary script language statements (and its cousin Apply that simplifies calling functions by name). Multiline strings, and in particular multiline strings surrounded by triple quotes (the """ sequence of chars), since they allow string literals inside them naturally, as one would do in a normal AviSynth script. The Import() statement that allows execution of arbitrary scripts, which can return a value (not necessarily a clip; a script can return a value of any type, which can be assigned to a variable of the calling script). Recursion (the ability to create recursive functions). Control functions, in particular Assert, Select, Default and NO

These are several different ways to represent colors. For example: YUV and RGB colorspace. In YUV colorspace there is one component that represent lightness (luma) and two other components that represent color (chroma). As long as the luma is conveyed with full detail, detail in the chroma components can be reduced by subsampling (filtering, or averaging) which can be done in several ways (thus there are multiple formats for storing a picture in YUV colorspace). YV12 is such a format (where chroma is shared in every 2x2 pixel block) that is supported by AviSynth. Many important codecs stored the video in YV12: MPEG-4 (x264, XviD, DivX and many others), MPEG-2 on DVDs, MPEG-1 and MJPEG. The subsampling used by YV12 is also called "4:2:0" compared to "4:2:2" which is used by YUY2 and UYVY. Where can I download the latest stable AviSynth version which supports YV12? "AviSynth v2.57" (and more recent versions) can be downloaded here. Where can I download the DGIndex/DGDecode plugin, which supports YV12, to import MPEG-1/MPEG-2/TS/PVA in AviSynth? The latest DGIndex/DGDecode combo can be downloaded here. Which encoding programs support YV12? The regular builds of Virtualdub (by Avery Lee) have YV12 support in fast recompress mode since v1.5.6. There are also two another options for encoding to

The file(s) opens in VLC Player and VirtualDub. I installed all the related codecs and plugins like FFDShow, AC3 Filter, reinstalled AVISynth, updated meGUI, but no luck. I also Googled a lot, but couldn't find any similar posts or solutions. Hoping to get a solution here. Thanks!

Quote 27th Jan 200921:20 #3 th3obr0 View Profile View Forum Posts Private Message Member Join Date : Jan 2009 Location : United States Yea it has worked 3-4 times, bit not more. I every time get this error. Those 3-4 times were only when I did a clean install twice - Uninstalled and reinstalled meGUI and AVISynth. EDIT: I just realized that AVISynthWrapper.dll is in meGUI folder. I quickly reinstalled meGUI, but didn't update it. It worked! Then just to test it, I updated meGUI. WOLLA! The update corrupts the DLL file.
