FFVideoSource v. DGAVCDecode v. ...?

I've seen a whole bunch of input filters being tossed around, between DirectShowSource, FFVideoSource, AVCSource (from DGAVCDecode), and a whole bunch more, but there doesn't seem to be any reasonable explanation of why to use one over the other or what the differences are. I've heard some talk about DirectShow somehow not being deterministic. Can anybody explain?

a good review http://avisynth.org/mediawiki/FAQ_loading_clips

AVI: avisource (internal)
AVC/MPG/VC1 DGDecNV (requires a supported Nvidia graphics card) and discussion

MPEG 1/2 DGINDEX


AVI, MKV, MP4, FLV, WMV, OGM, VOB, MPG,M2TS, TS ffmpegsource- ffvideosource ()

for everything else:


directshowsource

or

dss2

(and needed Direct Show components)

Plus some esotheric decoders like RawSource, but if you should use then you don't need advice.

That's where the 'non-deterministic' part comes in, as the behaviour depends on what DirectShow components you have installed on your sytem.

Yes, but what would be the difference if I were to drag an m2ts file into DGAVCDecode and use AVCSource versus using the m2ts directly with FFVideoSource?

From what I read here DGAVDecode is the optimal tool, FFVideosource may exhibit strange behaviour sometime (there is a recent thread in first page, with a post of Didée).

My notebook has a AMD/ATI graphic card therefore I haven't any direct experience with neuron2's tools.

Naw, it's broken for most PAFF streams, and anyway, the author does not license it for public use and no longer supports it.

I' m sorry, of course you are right. I meant DGDecNV (see my comment about graphic card)

DGDecNV more unpredictable than DGAVCDecode for me. And cost money.
Only one think it can made better is decode VC-1 Interlaced.

Care to elaborate on that statement? In what way is it less predictable (or "more unpredictable")?

avisource and directshowsource both rely on the appropriate decoders being installed on your system. ffms2 is the only general-purpose source plugin that doesn't have that limitation. on the other hand it has its own issues; some formats suffer more than others.
