  • Get blur effect inside a drawn box using ass format

    18 septembre 2024, par Armen Sanoyan

    I have Nodejs application which generates subtitles file for video editing. The editing is done by ffmpeg. For each word I also generate a backdrop with rounded corners using drawing command. Example of dialog for backdrop.

    


    Dialogue: 0,00:00:38.60,00:00:42.10,Default,,0,0,0,,{\p1\1a&HD8&\c&HE27FA4&\pos(341.07421875,517.5)\an4}  {\p1}m 15 0 b 1202.8515625 .... {\p0}


    


    Now I want to make the backdrop blur.
(Text backdrop by ass formatting)

    


    I have tried to use \blur or \be, but they are for other purpose. Below is reference from the doc

    


    Enable or disable a subtle softening-effect for the edges of the text

    


    Is there any other way to achieve the blurred backdrop. I am ready even to mix ffmpeg commands like boxblur and ass file. I mean separately paint the backdrops and then apply ass subtitles file. Here is an experiment to explain the idea.

    


    [0:v]split=3[base][blur1_in][blur2_in];

[blur1_in]crop=w=100:h=100:x=20:y=40[region1];
[region1]boxblur=luma_radius=10:luma_power=1[blurred_region1];
[base][blurred_region1]overlay=x=20:y=40:enable='between(t,0,5)'[tmp1];

[blur2_in]crop=w=30:h=30:x=20:y=40[region2];
[region2]boxblur=luma_radius=5:luma_power=1[blurred_region2];
[tmp1][blurred_region2]overlay=x=20:y=40:enable='between(t,5,10)'[tmp2];

[tmp2]ass=../logs/ass.ass:fontsdir=../fonts/Audiowide-Regular.ttf[final_video]


    


    The problem in this case is that the corners are not rounded. Could anyone explain to me what is the easiest way to get backdrop with rounded corners an blurred inside

    


  • Is it possible to use ffmpeg in nwjs native addon in linux ?

    16 octobre 2016, par Sergey Yakimov

    I’ve created native addon for encoding video from IDS camera. It work in nodejs but after rebuilding it with nw-gyp it stop working. I checked available encoders and there is none. When nwjs loads addon I think it using ffmpeg which come with nwjs and it have only few decoders compiled in and no encoders. In nwjs docs they only describe how one can enable h264 codec, but if I understand it right it will work only as decoder.

    So is there a way to make addon use system ffmpeg instead of that what come with nwjs or at least rebuild ffmpeg used in nwjs to include encoders in it ?
