Test build VirtualDub2 v2.5.2.1123 (https://disk.yandex.ru/d/R3Ob8yREy4ChvA)
Fixed display of the duration of the selected range in the status.
Potential memory leaks have been fixed.
32-bit "PICVideo Lossles JPEG Codec" (pvljpg20.dll) is not supported because it crashes when opening the video compression selection window.
Fixed video capture with compression in the "FFmpeg FFV1" and "x264 8 bit" codecs.

You are right, thank you. :)
Sorry about that!

However that's kind of confusing at the virustotal page.
I always thought that by entering an URL there would make unnecessary to d/l the file,
but have virustotal analyse the file directly from the URL given.
This doesn't seem to be possible?

How do I set the time format to this: 0:00:06.95 What time format? Where?

[nji]

I was about to use an external encoder (for the first time) of ffmpeg.

What I need is to encode the video, leave the audio as-is and put it into an mkv container.

But doing File/Export/UsingExternalEncoder I always get:
Invalid command line template: "-i - -c:v libsvtav1 -preset 5 -crf 22 -pix_fmt yuv420p10le -c:a copy "%file%""

What I did before:

Options/ExternalEncoders...
Have to define at the Encoders tab first. My entries:
Video Encoder
C:\<FullPathToFFMPEG>\ffmpeg.exe
-i - -c:v libsvtav1 -preset 5 -crf 22 -pix_fmt yuv420p10le -c:a copy "%file%"
%(outputname).video
I do not define an audio encoder in the other tab.
Next go to Encoder Sets
and define a set with only the former video encoder entered.
That's it.

What did I do wrong?

It is obvious that an encoder of the "Video encoder" type will not be given audio data.

[nji]

It is obvious that an encoder of the "Video encoder" type will not be given audio data.

OK, I removed "-c:a copy" from the video encoder's parameters.

Then additionally defined an audio encoder:
Command as of video encoder, options as:
-i - -c:a copy "%file%"
Input format: Raw audio data (or WAV file, doesn't matter).
Compression: Bypass...

Next added the defined audio encoder to the encoder set.
(Still no multiplexer defined).

Then do the Export/ ExternalEncoder.
Message:
Invalid command line template: -i - -c:a copy "%file%"

What might be obviously wrong now?

[nji]

Very strange... there seems to be no knowledge in the forum how to use external encoders :confused:

However I just discovered that your app can't read vdscript files (saved by itself), whereas orig VD2 has no problem with.

Sticky: VirtualDub External Encoder Tutorials (https://forum.doom9.org/showthread.php?t=171141)

[nji]

I already saw that source, but as it is as old (for VD1.10!), I wouldn't have expected that these entries do still work for VD2.x.

OK, with them I tried a simplified example:
source: h264+aac movie.

wanted destination: x265 lossless + audio copy.
ffmpeg CLI: ffmpeg -i SourceAVC1.mp4 -c:v libx265 -crf 0 -c:a copy s.mkv does fine.

Now define as external encoder in VD2.5:
Video encoder arguments:
-f rawvideo -c:v libx265 -crf 0 -i - "%(tempvideofile)"
Audio encoder arguments:
-i - -c:a copy "%(tempaudiofile)". Other tab: WAV file and bypass compression.
Addition simple muxing by ffmpeg of both defined.

What is wrong with this super-simple usage?

[v0lt]

What is wrong with this super-simple usage?
I think you forgot to pass the RAW Video parameters.

If the task is to encode only video, then a simple example is as follows:
Video encoder
ffmpeg.exe
-f rawvideo -s %(width)x%(height) -r %(fps) -i - -c:v libx264 -y %(outputname)
%(outputname)
You can also specify -pix_fmt and "-x264opts colormatrix=bt709" if needed.

This could be found in the link I wrote above.
Sample1 (https://web.archive.org/web/20191122113000/https://encodingtalk.com/threads/virtualdub-save-direct-to-mp4-fraps-to-youtube-with-external-encoders.2446/page-2#post-13731), Sample2 (https://web.archive.org/web/20150928230131/http://forums.virtualdub.org/index.php?act=ST&f=3&t=18840&st=120#entry93547).

[nji]

Thank you for your assistance :)

Acutually parameters width and height seem to be mandatory.
I didn't expect that.
I thought that VD2 just "calls" the encoder (same as in CLI).

Audio encoder, bypass compression:
It seems I misunderstood that.
I thought when defining an external encoder, it would be possible to
somehow leave the audio as-is (like the CLI ffmpeg command: -c:a copy).
But if I'm right, then that isn't possible at all?
By defining an external decoder, VD2 forwards the (de-compressed, if compr. bypassed) raw audio
to audio encoder, so you have to compress with the audio encoder again.
Right?
Or do I miss something?
Is it possible to pass-through the compressed audio stream from source
untouched to the muxer? :confused:

[v0lt]

Is it possible to pass-through the compressed audio stream from source
untouched to the muxer? :confused:
The Caching input driver (avlib-1.vdplugin) always decodes the audio.

Some other input drivers may output the audio track as is. But I don't know if this works with external encoders.

[nji]

Actually I use a Quicktime driver for Audio (per "Audio from other file..."),
if I don't change video timeline, and so audio can remain,
and doesn't have to be decompressed and recompressed again.
Works perfect within VD2.

But I haven't been successful in passing that compressed stream
to an external encoder.
And I haven't found any example/ explanation on that.
I wonder, as it seems a usual case.

Did anybody manage that?

[nji]

In my example:
Say I have an aac audio file (e.g. the as-is extracted audio track (aac)
from my video file; take AviDemux for extraction).
In VD2's external decoder thing: how do I get that to "%(tempaudiofile)"?
Using ffmpeg CLI the command is:
ffmpeg -i SourceAVC1.aac -c:a copy bitcopy.aac
So the definition for VD2 Audio Encoder should be like:
ffmpeg
-i - -c:a copy "%(tempaudiofile)"
Right?
When starting the external decoder set, it interupts after few seconds.

What time format? Where?

I mean, how do I change the time format from this (https://imgbox.com/n1AGDIZX) to this (https://imgbox.com/B6NMBQ0L)?

[nji]

I noticed that actual 32 bit VD records wrong colors (capturing a movie playing with MPC-HC).
Maybe some kind of flipping color components?

I enclose an example of orig VD2 versus actual VD2.5.1.1095.
Both 32 bit, both same settings (@ Win7-64).

Attachments in this forum require a release by a moderator. That can take some time. External hosts are recommendable.

Does it look like blue (Cb = U) and red (Cr = V) are swapped? This is a quite common issue with very similar YUV formats, possibly treating a FourCC wrong.

Yes, you're right... R and B are swapped.
But what caused it?
The settings in VD2 orig and VD2.5.1.1095 are the same...

This is not a bug.

I understand that opening the script three times via CID will remain, because that's how CID works?

[v0lt]

VirtualDub2 requests the video and audio tracks. The Caching Input Driver opens the video and audio independently. This results in two calls to avformat_open_input. Then, for some reason, VirtualDub2 requests the audio track again, resulting in a third call to avformat_open_input.

Perhaps this can be redesigned, but it doesn't seem straightforward to me. Especially since the Caching Input Driver works well in many cases.

[v0lt]

Test build VirtualDub2 v2.5.2.1131 (https://disk.yandex.ru/d/R3Ob8yREy4ChvA)
...
Fixed loading of processing settings (script files).
Cosmetic changes.

Updated avlib-1.vdplugin to version 1.1.2.446.
- The FFmpeg 8.1 x64 build from BtbN is used.
- The FFmpeg 8.1 win32 build from Defisym is used.
- Fixed enumeration of video encoders when some video encoders were not available in the used FFmpeg build.
- Video encoders that cannot be used due to missing hardware or an unsupported driver will not be available for selection and configuration.

Thanks for the explanation.
However, this is a disadvantage if the AviSynth script performs some calculations (e.g. the first pass of some filter).

To v0lt.
Is there any chance you would review 10-bit video support?
The known to me issues are with internal filters downconvert 10-bit video to 8-bit.
And, in capture mode I get right half of the video in green when use display with filters option, even when there are no filters.

Thanks.

[v0lt]

Basic 10-bit support is available.
However, you won't be able to work correctly with Bt.2020, HDR10, HLG, etc. in VirtualDub2.

Yes. Many filters support a limited range of video formats. You might want to look for a more modern video editor.
And, in capture mode I get right half of the video in green when use display with filters option, even when there are no filters.
My webcam only supports YUY2 format (I looked in Video > Capture pin).

Sorry, old school.

Well, you have powerful tool in your hands.
In capture mode activate filters, add convert format filter and configure it to produce 4:2:2 YCbCr 16-bit. Then select Display with Filters and you'll see 10-bit video. :)

I understand what you're saying.
However, my suggestion to use filters was just to simulate real 10-bit video for testing purpose.
Nowadays I don't use filters in capture mode, but I did use them in the past and didn't have any unexpected issues.
I think the problem is with displaying the video, not with the processing because the capture itself comes out just fine.

[v0lt]

Try processing the video after capturing and writing it to a file.

[mts1]

Try processing the video after capturing and writing it to a file.
Never had any issues with viewing/processing 10-bit video file with or without any filters.
The only condition I know, which produces the "green", is Viewing with filters in capture mode. I usually need it for built-in histogram.

Is VirtualDub2 on GitHub?

That's indeed a very complex question, that is discussed by many experts since years. There are academic papers on all the aspects of that issue.
It can't be answered by a simple Yes or No.
