Can't create a WebM with VirtualDub FilterMod

[Bruce Banner]

I'm trying to use the WebM (Opus) encoder set.

The command arguments for the V VP9 video encoder are -y -f rawvideo -s %(width)x%(height) -r %(fpsnum)/%(fpsden) -i - -f webm -c libvpx-vp9 -b 0 -crf 18 -threads 8 -speed 2 -tile-columns 6 -frame-parallel 1 -auto-alt-ref 1 -lag-in-frames 25 "%(tempvideofile)"

The command arguments for the A Opus @~192K audio encoder are -y -i - -f ogg -c libopus -b 192K -vbr on -compression_level 10 "%(tempaudiofile)"

I keep getting an "anonymous pipe" error. How do I fix it?

[Bruce Banner]

Nothing? No suggestions?

[pandy]

It looks like ffmpeg doesn't receive data from pipe (at least error type and ffmpeg command-line suggest such problem) - if you are desperate you can always use ffmpeg directly with your video outside virtualdubmod.

Show the log (F8) - it should show any ffmpeg errors.

Cant be problem the video is mod2 only? I know nothing about VP9 to be honest, but suppose it couldnt be problem nowadays.
If you add 1pixel to each side you get mod 16 and it is probably better for compression?

1 pixel? Wouldn't I have to add 2? If I added 1 to each side, the video would be 719x575.

[Bernix]

of course I meant left right top and bottom...
EDIT: If I were bad man, I take your remark personally. With such attitude, you can't search for help. Please use your brain.
And yes, I know my english is very very poor, but I can still recognize even and odd numbers.

Oh yeah, of course, sorry, brain freeze.

Sorry, how do you do that?

From "Configure External Encoders", press "Export...", save to file.
If you can, delete everything irrelevant (if you have many other presets).

I don't know ffmpeg that much but this command also fails. This is weird

copy test.bin | ffmpeg.exe -y -f s16le -ar 48000 -ac 2 -i - -c libvorbis test.ogg

Stream #0:0 -> #0:0 (pcm_s16le (native) -> vorbis (libvorbis))
Multiple frames in a packet from stream 0
[pcm_s16le @ 029029e0] Invalid PCM packet, data has size 1 but at least a size of 4 was expected
Error while decoding stream #0:0: Invalid data found when processing input

To me it looks like its pipe reader is broken, but this is insane. Any ideas?

At least it's not just me then. That's something. What's test.bin?

[shekh]

Sorry, used wrong command. Should be type instead of copy, works this way.
But it is interesting that wrong command resulted in same error messages as in VD log. Need to look further

test.bin is raw audio for this test, to make it repeatable just in case.

Ah, OK. In the meantime, as you're looking further, is there anything you'd advise me to change about the command arguments? Should I look for copy and change it to type?

Ah, seems I can't find the word copy.

It works for me with these presets using the webm(opus) encoder set on a random youtube video

The only thing I changed was the ffmpeg path

(tested using vdfm 40176)

[poisondeathray]

Maybe try updating your ffmpeg binary ? Where/when is it from ?

ffmpeg version N-72086-g51f6455 Copyright (c) 2000-2015

Probably older.... I think it's 2017 now ? Yep. Almost 2018

Hi. I just downloaded ffmpeg 3.4.1 but I've no idea how to update.

[poisondeathray]

Unzip it somewhere , and update the paths in the external encoder settings (your 1st post)
e.g. Instead of C:\Users\Bruce\Desktop.... , change to wherever the newer ffmpeg.exe is located

There doesn't seem to be a newer one. I unzipped the ffmpeg-3.4.1 folder to my desktop but there's no ffmpeg.exe in there.

[poisondeathray]

it's probably in a subfolder somewhere usually it's in the folder "bin" for binary

[Bruce Banner]

Nope, I searched with this app called Everything that looks at all the files on your computer; there's no ffmpeg.exe in that folder. And there's no bin folder either. I've got all the subfolders listed in alphabetical order; the first one's compat

[poisondeathray]

where did you download it from ? I usually get precompiled windows ffmpeg binaries from zeranoe
https://ffmpeg.zeranoe.com/builds/

That could explain it then. I just Googled ffmpeg and downloaded from the first hit.

https://www.ffmpeg.org/

EDIT: Hey, great, that did the trick, it worked! I downloaded from zeranoe and the new ffmpeg worked fine! Thanks!

[pandy]

Beware of older ffmpeg that can be present in your path environment - lot of programs install ffmpeg on their own silently and later when you call ffmpeg you may receive errors as old ffmpeg build may be used instead desired one. Best idea is to search ffmpeg.exe on ALL local disks. This is quite common issue.
Alternatively you can modify path to point current ffmpeg first. Substituting older ffmpeg.exe by new one is not recommended as some difference may occur in syntax and you will get unexpected error from applications.

[shekh]

So the problem was filename conflict
Instead of

"outputFilename": "%(outputname).webm"

Should specify distinct names for audio/video

"outputFilename": "%(outputname).Audio.webm"
"outputFilename": "%(outputname).Video.webm"

The problem I saw with invalid pcm packets remains but it is something not critical, the encoding finishes.

[Bruce Banner]

Great, thanks for the advice, guys!
