Encoder ffmpeg missing in application path.

[Ivanotchsky]

QTv1.14

Everytime I attempt to export selected ml raw clips - whether that be one or multiple at a time - that error messages pops up.

managed to export one clip but haven't managed to do any others no matter the adjustments if none at all and retried to export originally successful clip to no avail.

(export settings - h.264 at either high or medium ffmpeg .mp4)

Hi,

• What (exact) version are you using?
• What OS do you use?
• Have you checked, if ffmpeg is located in MLVApp application path (same path as MLVApp executable)?
• Have you checked e.g. your antivirus, blocking the tunnel between MLVApp and ffmpeg?

Hello @masc4ii, I am running into the same issue with v1.14 OS Linux Manjaro, I have these files (containing ffmpeg in name) in the application path, am I missing something please?

$ ls -R | grep ffmpeg

EDIT: I found out that this issue happens only when using locally built app. However when using AppImage, exports are working, I have trouble with focus dots not being installed in the AppImage, therefore I have to use locally build.

EDIT2: I managed to resolve this issue by downloading the ffmpeg v4.4.1 binary and moving it into MLV-App/platform/qt folder :partying_face:

Please read this for focus pixels and appimage: https://github.com/ilia3101/MLV-App/wiki#fix-focus-dots

You must not download ffmpeg. It is included in the repo you already downloaded, for x86_64 at least. Just unzip, if Qt does not do this automatically on deployment.

I tried unzipping it, but it didn't work because I did not know it has to be placed in the platform/qt directory. I think the Qt haven't placed it in the correct location during the build & installing

[masc4ii]

Place it into the application path (path where MLVApp.exe is located). platform/qt is not correct - no idea why this shall work for you.

[peterslany]

In my case the mlvapp executable (no .exe since I'm on linux) is located in the platform/qt directory probably because I built and installed it in there - according to the steps in the guide. That's why it works I guess : )

[masc4ii]

If you install the executable to this path, then yes, ffmpeg has to be in exactly this path too.
