.avs shows fine but ffmpeg creates black video

[Starduster]

I'm not sure what I'm doing wrong. I have an .avs file:


sld1 = DirectShowSource("2023-04-22 21-48-24_3.mp4", fps=27.97, convertfps=True)
sld1=sld1.ConvertToRGB32().Spline36Resize(1280, 720).SSRC(22050)

sld2 = DirectShowSource("RickettsRodman.mp4", fps=27.97, convertfps=True)
sld2=sld2.ConvertToRGB32().Spline36Resize(1280, 720).SSRC(22050)
sld2=sld2.LanczosResize(930,720)
sld2=sld2.AddBorders(175,0,175,0)
sld1 ++ sld2


When you play the .avs it looks fine. But I'm trying to create an .mp4 with ffmpeg and I have audio but a black screen. I've tried a number of different arguments:


ffmpeg -i test.avs output.mp4
ffmpeg -i test.avs -vcodec libx264 output.mp4
ffmpeg -i test.avs -v:c libx264rgb output.mp4


Feel like I'm just guessing now. What did I do wrong?

[StainlessS]

Maybe try variations of below to figure out problem. [1st step is to find out if problem is in your script, or ffmpeg command (or both)]

Colorbars(width=1280,height=720)
Trim(0,-1000) # 1000 frames

ConvertToYV12() # Test problem is with RGB32 (EDIT: maybe ffmpeg dont like the alpha channel, and so is black, perhaps RGB24 would work)
#Assumefps(27.97) # Your Non standard framerate
#Assumefps(24000,1001) # 23.976
Assumefps(30000,1001) # 29.97

Return last


As supplied above (and with my ffmpeg.exe), first two ffmpeg commands OK,
but third produces

c:\Z>ffmpeg -i test.avs -v:c libx264rgb output.mp4
Invalid loglevel "libx264rgb". Possible levels are numbers or:
"quiet"
"panic"
"fatal"
"error"
"warning"
"info"
"verbose"
"debug"
"trace"


EDIT: Not sure, but does "-v:c" not mean "copy video", with isolated (ie without any indicated) meaning of "libx264rgb" unpredicatable (at least by me).

c:\Z>ffmpeg -i test.avs -v:c libx264rgb output.mp4


EDIT: below same red error (invalid loglevel) output as above

c:\Z>ffmpeg -i test.avs -v:c output.mp4


EDIT: Below works.

ffmpeg -i test.avs -vcodec libx264rgb output.mp4

EDIT: I usually use BAT files similar to above BAT file to extract 'difficult' video to AVI for simple AviSource() input, where
other Avisynth source filters have difficulty reading a clip. (hence tendency to use Lossless encoders)

EDIT: Might also benefit from investigation of below in blue (maybe -b:2 means stereo, and 96k is bitrate)

ffmpeg -i test.avs -vcodec libx264 -acodec aac -b:2 96k output.mp4


EDIT: With script "ConvertToYV12()" commented out [ie RGB32] and "-vcodec libx264rgb", produces good output.

I kinda suspect that problem might be your ffmpeg.exe,
here:- https://www.mediafire.com/file/xa1zbft5l16ysjq/ffmpeg.7z/file
the one I'm using (I think maybe by PatMan), supports avs input, perhaps yours dont properley support it.
Maybe not the most recent version, but not so old (maybe about XMas issue).
Is static linked, ie no dll files needed.

[Starduster]

I downloaded that ffmpeg and got the message that I'm using a 64 bit Avisynth... Took a look and I was using Avisynth+ on this machine. So I uninstalled that and found I had 2.58, 2.60, and Plus. Not sure what I should be running but installed 2.60 and tried. Playing the .avs by double-clicking still worked but this time using:

ffmpeg -i _Atest.avs -vcodec libx264rgb -acodec aac _output.mp4


I get "unknown error occured." I assume the ffmpeg.7z you referenced is 32 bit... which should match the Avisynth 2.6. Wondering if it's something in the .mp4 that's odd. Here is a link to one of them. http://chloericketts.com/video/rickettsrodman.mp4
and I'm using Atest.avs:


sld2 = DirectShowSource("RickettsRodman.mp4", fps = 30, convertfps = True)
sld2=sld2.ConvertToRGB32().Spline36Resize(1280, 720) #.SSRC(22050,fast=True)
sld2=sld2.LanczosResize(930,720)sld2=sld2.AddBorders(175,0,175,0)
sld2

[StainlessS]

I'm using Avs+ x64 (dont even have x86 installed).

Yes, I think you may be correct that is x86 ffmpeg
I think maybe Patman exe I was thinking of is x264 or x265, and the ffmpeg.exe I use/posted is by the guy that still supports XP compatible x86 ffmpeg,
so I think should work on both x86 and x64 machines,
Works for me on x64 machine with x64 AVS+, and x86 ffmpeg.exe.

FranceBB knows the guys name that supports XP compatible ffmpeg x86 (name begins with "R" I think).

So far as I know, it should not matter if ffmpeg is x86 and Avs+/plugins are x64, ffmpeg is simply using output of AVS+ x64, as input to ffmpeg.
Well it works for me with mismatch in avs+ [x64] and ffmpeg [x86].

I assume the ffmpeg.7z you referenced is 32 bit

You have to extract the exe from the compressed 7z file (like zip file) use 7Zip, or I imagine WinZip and WinRar can also extract it).
And I suggest that you call my ffmpeg.exe like so, (with full path)
"D:\ffmpeg.exe -i _Atest.avs -vcodec libx264rgb -acodec aac _output.mp4"
So you are using the right one. If works better than can replace the ffmpeg.exe wherever it resides on your machine.

Nope, the one I thought I might be using was from Reino (ffmpeg-5.2-2131-fcd557a-win32-dev-xpmod-sse.7z):- https://rwijnsma.home.xs4all.nl/files/ffmpeg/
but big difference in sizes.

[Starduster]

Yes, I have 7zip and used its ffmpeg.exe for my test. That's the one that gave the error... but now it's using the Avisynth 6.0 which is 32 bit. Were you able to use the file and avisynth code I referenced with any success?

[StainlessS]

With same ffmpeg and same avs+ x64,
script [I changed to LSmash, DirectShowSource is infamous for its being not frame accurate,and output was a bit choppy]

#sld2 = DirectShowSource(".\RickettsRodman.mp4", fps = 30, convertfps = True)
sld2 = LSmashVideoSource(".\RickettsRodman.mp4", fpsnum = 30, fpsden = 1)
sld2A = LSmashAudioSource(".\RickettsRodman.mp4")
sld2 = AudioDub(sld2,sld2A)

sld2 = sld2.ConvertToRGB32().Spline36Resize(1280, 720) #.SSRC(22050,fast=True)
sld2 = sld2.LanczosResize(930,720)sld2=sld2.AddBorders(175,0,175,0)
sld2

Maybe its your player that dont like RGB32, and shows as black due to Alpha channel.
(x264 RGBA in mp4 would also be a lot bigger I think).

[StainlessS]

Potplayer OK,
VLC OK,
MPC-HC (open OK from within MPC-HC via file menu), Windows Explorer right click open in MPC-HC does nothing.
Windows Media Player, shows Black Screen, same as your original problem.

Avoid RGB with Alpha Channel, ie use YV12 [Return ConvertToYV12() at end of script ]

EDIT: Ignore the MPC-HC problem, It dont open other files either, I must have a problem there.
EDIT: Damn, about 5->10 mintues after trying to open another mp4 in MPC-HC via Explorer right click, it jumped up and started to play,
perhaps Antivirus was scanning entire mp4 file or something.

EDIT: From the ffmpeg text output [looks like its any RGB within an Mp4 (and not just alpha) that is the problem for Windows MediaPlayer]

Stream #0:0: Video: h264 (avc1 / 0x31637661), rgb24(pc, gbr/unknown/unknown, progressive), 1280x720, q=2-31, 30 fps, 15360 tbn

[Starduster]

Well... thanks a ton for all that. I'm going to reinstall Avisynth+ and try again. The video player is just Windows Media Player. I'll let you know how it goes.

[StainlessS]

Yep, dont use Windows Media Player (that IS the problem), and avoid rgb in mp4, use YV12.

[Starduster]

You are correct. Media player won't play it but VLC and Chrome play it fine. I downloaded a new version of Avisynth+ and installed that with your ffmpeg. Thanks so much for the help!
