Apologies for dragging up an old post, but I am struggling with the output of Dashware when rendering the final video. All works well within the project to add/modify gauges and synchronize, etc, but I get an immediate Media Foundation error at the end when creating the output video. Hoping someone can set me straight. Using the latest Dashware 1.9 and understand it doesn't work without the video file containing some audio... so added some music to the DJI video MP4 file (lasting full length of the video) using Windows Movie Maker (as suggested in another thread). Still no success and the same error. Subsequently found this thread and tried downloading the FFmpeg.exe as suggested and using the batch file helpfully offered a number of posts ago to add silent audio... this alas fails to create the silent audio file, and gives me errors of 'silent_audio.mp3: Permission denied' and then 'silent_audio.mp3: No such file or directory'. I'm not sure if the video file is supposed to have ...audio appended to the file name afterwards but in my case it doesn't and the video file in the folder ultimately still doesn't render at the end of the project when used back in Dashware. I don't think the batch file worked for me. Can anyone help? thanks.
First of all, make sure to download the latest version of my package, version 5.1 (it's just a couple posts above). The batch file in the Audio Bug folder (ffmpeg_add_audio.cmd) creates the silent .mp3 automatically if it does not exist, but it seems that on your PC it fails because of permissions. Try running the .cmd file as an Administrator and see if that helps.
Using FFmpeg to add a silent track (or even a non-silent one) is better than Movie Maker as FFmpeg doesn't re-encode the video, it simply repackages the .mp4 to include the original video track, plus the audio track. In any case, what you have done with Movie Maker should have fixed the audio issue of DashWare, so maybe the problem is somewhere else...
