• How to use ffmpeg speedup video specific time range in one line ffmpeg cli [closed]

  18 mars, par chikadance

  I try following splited cli, they work well

  


  ffmpeg -i "$input_file" -filter_complex "[0:v]trim=start=0:end=10,setpts=PTS/10[v1];[0:a]atrim=start=0:end=10,asetpts=PTS/10[a1]" -map "[v1]" -map "[a1]" -shortest -t 1 "$output_file" -y
ffmpeg -i "$input_file" -filter_complex "[0:v]trim=start=10:end=13,setpts=PTS-STARTPTS[v2];[0:a]atrim=start=10:end=13,asetpts=PTS-STARTPTS[a2]" -map "[v2]" -map "[a2]" -shortest "$output_file" -y


  


  but when i merge them :

  


  ffmpeg -i "$input_file" -filter_complex "[0:v]trim=start=0:end=10,setpts=PTS/10[v1];[0:a]atrim=start=0:end=10,asetpts=PTS/10[a1];[0:v]trim=start=10:end=13,setpts=PTS-STARTPTS[v2];[0:a]atrim=start=10:end=13,asetpts=PTS-STARTPTS[a2]" -map "[v1]" -map "[a1]" -map "[v2]" -map "[a2]" -shortest -t 4 "$output_file" -y


  


  the result video last 3s is frozen, how to fix it

  


  If I found following answer, but it give multi lines ffmpeg solution, I hope one ffmpeg cli todo it

  I use FFMPEG plugin with Vue3 and Vite. My code :

  


  <code class="echappe-js">&lt;script setup&gt;&amp;#xA;import { FFmpeg } from &amp;#x27;@ffmpeg/ffmpeg&amp;#x27;&amp;#xA;import { fetchFile, toBlobURL } from &amp;#x27;@ffmpeg/util&amp;#x27;&amp;#xA;import {onMounted} from &quot;vue&quot;;&amp;#xA;&amp;#xA;// const baseURL = &amp;#x27;https://unpkg.com/@ffmpeg/core@0.12.6/dist/esm&amp;#x27; // doc - vite&amp;#xA;const baseURL = &amp;#x27;https://unpkg.com/@ffmpeg/core-mt@0.12.6/dist/esm&amp;#x27; // example&amp;#xA;&amp;#xA;const ffmpeg = new FFmpeg();&amp;#xA;&amp;#xA;onMounted(() =&gt; {&amp;#xA;    initializeFfmpeg()&amp;#xA;})&amp;#xA;&amp;#xA;const initializeFfmpeg = async () =&gt; {&amp;#xA;await ffmpeg.load()&amp;#xA;}&amp;#xA;&lt;/script&gt;&#xA;

  


  but FFMPEG is not initialized correctly.
the error occurs when I run the command :

• Can't get FFMPEG buildpack working in Heroku Node.js server (using Fluent-FFMPEG)

  30 juillet 2021, par Rayhan Memon

  I'm using a library called 'fluent-ffmpeg' on my Nodejs server that makes it easier to use an audio/video editing tool called FFmpeg, which is downloaded locally on my computer.

  


  When running on my computer, I point fluent-ffmpeg to the local executable files of FFmpeg and FFprobe on my computer, like so :

  


  import ffmpeg from "fluent-ffmpeg";

// When running locally, set FFmpeg and FFprobe path to the local executable files
ffmpeg.setFfmpegPath("C:/Program Files/FFMPEG/ffmpeg.exe");
ffmpeg.setFfprobePath("C:/Program Files/FFMPEG/ffprobe.exe");


  


  When deploying to Heroku, I must use an FFmpeg 'buildpack'.

  


  I've tried two :

  


  

  1. https://github.com/jonathanong/heroku-buildpack-ffmpeg-latest

  


  2. https://github.com/HasibulKabir/heroku-buildpack-ffmpeg-ffprobe

  


  


  Neither have worked for me. Whenever I use an FFmpeg command, I get the following error in my heroku logs :

2021-07-24T15:22:52.970992+00:00 app[web.1]: }


  


  How can I go about using fluent-ffmpeg in my Nodejs server when deploying to Heroku ?

  


  Thank you for the help in advance !
