Problem Encoding ITV HD

[peterson28]

hi,
when i encode itv hd-transport streams with megui, i get ugly artefacts like in the screenshot every few frames...
the original ts-file is fine though...
anyone know whats the problem and maybe even a solution for that problem?

Just a guess, but it looks like the errors you get with old ffdshow decoding of mbaff h.264 streams. So if you are using DGAVCdec (which still relies on an older libavcodec version), you often get this artifacting. One workaround is to use DirectShowSource() with CoreAVC or recent ffdshow build

here a sample:

maybe i should tell u also my workflow:
i index the ts-stream with DGAVCIndex, than open the file with this small avs-script with megui:

LoadPlugin("C:\Eigene Programme\ENCODE Apps\GordianKnot\DGAVCIndex\DGAVCDecode.dll")
AVCSource("ITV HD - Germany vs England [2nd Half]_cut_cut.dga")

this avs already has the artefacts...

dont think its a problem with my codecs, cause this method works fine with all tv channels but itv hd...

Why did you send us encoded file instead of source ts?????????????

Because he's obviously new here, these are his 2 first posts, and you weren't explicit in what you wanted?

Just a guess, though.
