[RESOLVED] DGAVCDecDI may need the same crash fix as DGDecNV

Dear Donald,

please check if DGAVCDecDI needs a similar fix as DGDecNV (loading at least one frame) as I get the same pseudo-crashes in ivfenc 1.5 (Nic's AviSynth mod) as I used to get with DGDecNV before Build 2026.

It can't be the same race condition because CUDA is not present.

However, if you can tell me how to duplicate it, I can investigate.

Still no reply for almost 3 months...

Anything else you may need?

I doon't know what ivfenc is, how to install it, or how to use it. Give me a step-by-step to reproduce your problem.

Happy New Year.

Donald, you are incredible... :ugeek: :roll: -- Really, I did not expect that you were unable to read my second reply in excatly this thread! :shock:

^ See above. Or below again (repost):


{1} I linked my post in the DGAVCDecDI thread elsewhere, where I described all details already[/url]«.

{2} Furthermore I linked »ivfenc 1.5 in Nic's modified version to accept AviSynth sources«.

Download the ZIP file {2} from Nic's webserver. Unpack it. It contains a command line executable.

Make an AviSynth script which uses DGAVCDecDI to read an AVC source video (similar to the source of "ED_0360_DI.avs" I posted in {1} in the ??? forum).

Use the "ivfenc.exe" contained in {2} to convert the AviSynth script with command lines similar to those reported in the source code of a sample batch file "ED_0360_700_ivf.bat" in {1}.

Hmm ... it may be better to repeat the posted sources here so you don't need to read the ??? forum again.

ED_0360_DI.avs

Code: Select all

LoadPlugin("E:\Programme\DGAVCDecDI\DGAVCDecodeDI.dll")
DGSource("ED_1080_CRF06_DI.dgi") # some 1920x1080 source; here: "Elephants Dream" encoded from PNG files with x264 --crf 6
Spline36Resize(640, 360)
ED_0360_700_ivf.bat - a sample batch to encode the above script with 700 kbps

Code: Select all

E:\Programme\ivfenc\ivfenc.exe --codec=vp8 --passes=2 --pass=1 --fpf=ED_0360.stats --best --threads=1 --token-parts=1 --end-usage=0 --target-bitrate=700 ED_0360_DI.avs ED_0360_700.ivf
E:\Programme\ivfenc\ivfenc.exe --codec=vp8 --passes=2 --pass=2 --fpf=ED_0360.stats --best --threads=1 --token-parts=1 --end-usage=0 --target-bitrate=700 ED_0360_DI.avs ED_0360_700.ivf
E:\Programme\MKVtoolnix\mkvmerge.exe -o ED_0360_700.webm -w ED_0360_700.ivf ED.ogg
Please change any directories according to your own structure.

I just executed your encoding process on WinXP32 using latest DGAVCDecDI 2025 and latest DiAVC 1.2.2. I successfully encoded the .ivf file and encountered no issues whatsoever.

Can you download 2025 & 1.2.2 to get the absolute latest and test it again? Both contain important fixes.

Thank you. May you also get what you deserve this coming year. :)
Donald, you are incredible...
Once again, thank you. Praise is a rare thing and I'll take as much of it as I can.

Good. DGAVCDecDI 2025 and DiAVC 1.2.2 (DiAVC *.ax files copied into DGAVCDecDI folder after re-registering). Re-indexed the *.264 file with the current DGAVCIndexDI.exe to a current ED_1080_CRF06_DI.dgi and checked:

VirtualDubMod opens and displays the video well.

ivfenc ... thinks 3 seconds, then does nothing. Seems to crash and close without any notice. Nothing to read on the console.

Code: Select all

T:\Videos\Elephants Dream>E:\Programme\ivfenc\ivfenc.exe --codec=vp8 --passes=2 --pass=1 --fpf=ED_0360.stats --best --threads=1 --token-parts=1 --end-usage=0 --target-bitrate=700 ED_0360_DI.avs ED_0360_700.ivf

Any idea how I could help you further?

Well, VP8 developed in the meantime; ivfenc is now called vpxenc. Unfortunately, noone seems to be able to modify its sources so that it can accept AviSynth input. Not even porting Nic's ivfenc patch sources to the current vpxenc sources seems to be possible for anyone. Hard to find people with both enough interest in WebM and enough experience in coding C++ (incl. knowing a compiler in detail). I lack in the second.

Marking resolved as I have no bandwidth to work on vpxenc.
