"MPEG2 Source" Question

[t_2]

1. Could someone explain to me why GPL programs (AviSynth, VirtualDubMod, etc., seem to rely on DVD2AVI to open MPEG2 files? I remember reading on Ben's original AviSynth site that he had an MPEG2Source filter that he didn't want to release for fear of being sued. 2.In that case couldn't it be released separately as a plug-in?

It seems that there are problems with the DVD2AVI derived filters, which some fix filters only partially correct.

3. Since the new wave in DV seems to be MPEG2 based, i.e., the new HDV standard, does anyone know about new MPEG2Source projects in the works? 4. Or is DirectShowSource the way to go???

Thanks, T_2

Using Virtualmod-AC3 Ver. 1.5.4. alone I don't beleive it uses DVD2AVI program to open a Mpeg2 file. I use MPEGDECODER.DLL I do thinke it is true that Avisynth 2.54 does. It is possible now to edit HD Mpeg2 fromat 1920x1080 in VDMOD.

I don't know what is in the future, somebody else needs to comment on that.

Creating an index file is the safest way to allow for random access, which is critical to most Avisynth operations. If all you need is linear editing (e.g. a VDub dub), 1-pass parsers should be good enough.
