  • Connecting Firebase to a Computer to Run Programs for It [closed]

    29 mars 2020, par Rainbow Luv Sheep

    Currently I’m using Firebase to store video files sent by an app so that then ffmpeg can stitch them together and send a completed video back. However, ffmpeg will apparently sap up all of the allocated CPU usage of Firebase’s cloud functions since video files are large, and could possibly timeout. Because of that, I want to have Firebase sent a request to a computer that will download the video files, run ffmpeg to stitch them together, then upload that finished file back up to Firebase. App Engine and Compute Engine are out of scope due to cost .

    Is there any way to do that ?

    Sorry if I missed some obvious solution. I’m very new to working with servers in general.

  • FFMPEG Multiple Alpha Overlays

    16 septembre 2018, par AK47

    I have a few videos with alpha channels that I will like to overlay on top of each other. It’s possible to get working with the following command

    ffmpeg -i back.mov -i front.mov -filter_complex overlay -c:v png output.mov

    However if I add another video to this it no longer works

    ffmpeg -i back.mov -i front.mov -i front2.mov -filter_complex overlay -c:v png output.mov

    Does anyone know a way of getting this to work ? or would I have to output the first 2 layers and then run the code again with a new layer ?

    I will have more than 3 layers so looking for the most efficient way.

  • How to properly specify font file for ffmpeg as it's always defaulting to Arial ? [closed]

    21 avril 2024, par Jim Jans

    When calling ffmpeg it keeps defaulting to Arial-MT / Arial-BoldMT even when specifying a font. How do you correctly specify the fontfile ?

    


    When specifying any font it will always default back :

    


    [Parsed_subtitles_0 @ 000001915a83f800] fontselect: (DosisBold, 400, 0) -> ArialMT, 0, ArialMT

    


    I am calling ffmpeg with the following command :

    


    ffmpeg -i input.mp4 -vf subtitles='subtitle.srt':force_style='FontName=DosisBold,Alignment=10,Fontsize=24' output.mp4 -loglevel debug

    


    I have a file called "DosisBold.ttf" in the same folder as ffmpeg. I have already tried FontName=DosisBold.ttf and it also doesn't work. All files are in the same folder as the ffmpeg.exe.

    


    I have converted the .srt file to .ass and specified the font file but it still defaults back to ArialMT.

    


    Format: Name, Fontname, Fontsize {...}
Style: SubStyle,DosisBold,24 {...}


    


    I am using "ffmpeg-n7.0-latest-win64-gpl-7.0", I have tried different versions of ffmpeg (e.g. "ffmpeg-master-latest-win64-gpl") and still no change. Also tried different fonts / font files and it always defaults back to Arial.
