ffmpegsource & vc1

pwolfamv · 2nd April 2008, 07:10

I'm wondering. I see a lot of guides out there that use directshowsource for their HD-DVD/BD vc1's to * conversions... is there a way to get ffmpegsource to work with vc1? As far as i know, and from experience, ffmpegsource is more reliable and frame accurate compared to dshowsource. does this even matter with vc1 sources? Any info would be appreciated.

DirectShowSource is very reliable - provided you build a filter graph with GraphEdit ahead of time

I assume part of the problem getting ffmpegsource working is the EVO / M2TS containers... the elementary streams would probably work fine.

that work (ffmpegsource 1.16)

FFmpegSource("vc1.m2ts",vtrack=-1,atrack=-2,vcache=false,seekmode=-1)

Nice! I will try it with a MKV containing VC1 remuxed from the HD-DVD multiple EVO source that I'm working on!

The one qualm that I have with DSS is that ffdshow usually goes into the graph, and I typically have it configured for playback post processing. Obviously this has no place in an encoding workflow

Because ffdshow usually has all kinds of postprocessing and filters for watching videos activated which you probably don't want happening when processing the video with AviSynth's own filters.

Forget to at least change ffdshow's preset to a neutral one and you have one long encode ready to throw out on your hands...

np: Pan Sonic - Kuumuudessa Muodostuva / Forming In Heat (Katodivaihe / Cathodephase)

I guess its good that I've always kept it on nuetral settings then! Thanks for the info...

Blue_MiSfit · 3rd April 2008, 20:27

Exactly

Especially since I usually 4 tap lanczos resize to screen resolution (1920x1200), and add about 20 luma noise with modified settings!

That doesn't work at all when you're encoding stuff!

Apparently notify doesn't work on this forum -_-

Anyway, i'll try out that build of ffmpegsource, thanks!

Yea, it's working now. I was using a really old build >.< thought i had downloaded a newer one not too long ago but I must have copied to the wrong folder and just never did anything with it, lol.

Thanks for the help, really appreciated it.

Wanted to add:
I noticed this earlier with directshowsource... i'm getting a 19.982 framerate in vdub. Know why thats happening?
