Can not install dclFFMSource250.bpl,Why?

[sxbug]

When I installed dclFFMSource250.bpl,the error msg displayed: can not load package, The specified module could not be found.(Win 10 64Bit, Delphi 10.2.3)

Verifying OpenCV dependencies checked: ------- Verifying Microsoft DLL ------- OK ------- OpenCV DLL ------- OK ------- Delphi-OpenCV classes DLL ------- OK ------- FFMPEG DLL ------- OK ------- SDL DLL ------- OK

How can I do?

Thanks

This has never happened and here again ... Problem solved?

[sxbug]

No solved. I can not install it anyway.

Microsoft DLLs, OpenCV DLLs, Delphi-OpenCV classes DLLs, FFMPEG DLLs, SDL DLLs should be available to any program through the system variable PATH or located in catalogs according to the instructions - https://github.com/Laex/Delphi-OpenCV#requirements

Perhaps they are only available to the CheckCVDep.exe.

In my case, I got some error, but fixed.

environment: win8.1, 32bits,delphi xe10.2.3

error1: ocv.comp.FFMSource.pas - CODEC_CAP_TRUNCATED not define if (pCodec^.capabilities and CODEC_CAP_TRUNCATED) = 0 then pCodecCtx^.flags := pCodecCtx^.flags or CODEC_FLAG_TRUNCATED; ( we dont send complete frames )

fixed: rename CODEC_CAP_TRUNCATED to AV_CODEC_CAP_TRUNCATED

error2: dclFFMSourceXXX.dpk can't be istall, need avutil-56.dll FFMPEG 3.4.2 only has avutil-55.dll

fixed: install both FFMPEG 3.4.2 and 4.0.0

[sxbug]

It can be download here: FFMPEG 4.0.0 https://ffmpeg.zeranoe.com/builds/win32/shared/ffmpeg-4.0-win32-shared.zip https://ffmpeg.zeranoe.com/builds/

cc to Laex, thank you and your team member, the project is real cool! ( I had used c++ to develop opencv code, it is real not convenience than using delphi....)

[sxbug]

Yes. After I copied ffmpeg 4.0 's dll to sysWOW64 , I can install dclFFMSource250.bpl

Thanks
