No decompressor found for fourcc ffvh

[SQ]

I have this huffyuv clips, that were supposedly encoded to yuv2. I say that because, that's what I put in the settings.
The videos work in windows media player, but Premiere and VDub won't read them.

the .avi files give me the error "Couldn't locate the decompressor for FFVH (unknown), VirtualDub requires a Video For Windows (VFW) compatible codec to decompress video. DirectShow codecs, such as those used by Windows Media Player, are not suitable."
Not wanting to transcode these files again, I made a small avisynth script, simply using AVISource.
This does not help because I still get the error, but it's slightly reworded. "Avisynth open failure: Could not locate a decompressor for fourcc FFVH."

.... Help.

FFVH is FFDShow's huffyuv implementation. It is much better than standard huffyuv, both in speed and compression, however virtualdub does not take it, nor can avisource. You can load it just fine through ffvideosource, though.

I'm using the x64 avisynth and virtualdub.
When I use ffvideosource, Virtualdub locks up and quits responding. I have to manually end the process each time I try to open this.

I'm unsure I would like to attempt loading this into Premiere.

Code: Select all

LoadCPlugin("C:\Program Files (x86)\AviSynth 2.5\plugins64\ffms2.dll")
FFVideoSource("C:\CONTENT\Video\Gurren lagann\avi\15.AVI")
KillAudio()

Edit: The same string works just fine with mp4 files.

FFVideoSource does not load audio by default, so you're good.
As for halting vdub, it's due to the fact that ffms2 makes index files the first time it loads a video. And the bigger a file is, the more it takes to index. Incidentally, lossless files are huge, so that's prolly why it's having difficulties. If you check, along with the ffms2.dll, there should have come a ffindex.exe and an avsi. If you try to drag and drop your file over the ffindex.exe, it will open a cmd prompt and it'll start indexing. Once that is done, you will be able to load the script in virtualdub or anything else just fine. If however you don't have ffindex.exe (I haven't tried download the 64bit version of it to check, so it might actually only have the dll and maybe avsi), then get that exe out of the 32bit version of ffms2. You won't need this dll or avsi, but the exe will help out, as I believe that the index file is the same regardless if the dll is 32 or 64 bit.

I'm going to assume it's different, because I put it on my desktop and it said ffm2 wasn't installed.
I put it in my plugins64 folder with my ffms2.dll, and it said it could not start correctly.

The 64 version of ffms2 was only the dll file.
Bah.
All right, well, each huffy is about 20gb. So I'm going to assume I'll need to batch import these to Premiere and leave my computer on overnight?
Or would that fuck up everything?

So much crap has changed in 4 years. It's like I have to relearn everything.

[mirkosp]

I have ffindex.exe in my plugins folder along with ffms2.dll, but any folder will do. Try to keep the 32bit dll along with the .exe and drag and drop the video over the exe again, perhaps both in the folder of the video itself for the sake of ease.

For the record, VDub and avisource can both load ffvh if you have a VFW ffdshow filter.

Well, I feel dumb now: I did forget to enable libavcodec for huffyuv in ffdshow-tryout's vfw settings (why isn't it on by default, anyway?).

[Mister Hatt]

Depends how you installed it. Sometimes it's default, other times it isn't.

[SQ]

libravcodec was enabled in my settings. I had googled this problem before I made the thread and that was a suggestion in one of the results. It still wasn't working for me, though.

Anyway, Rather than trying to mess with that exe I just let it index in Premiere. It took a while but I eventually got them all to load and everything works great now.
Thanks for the help.
