• Efficient Video Compression with ffmpeg.js

  24 mai 2024, par John Mark

  I attempted to upload and compress a video using ffmpeg.js. However, it appears that this process is ineffective on modern browsers. I have already implemented console logging to verify if the video compression is occurring, yet thus far, no compression has been achieved. Could anyone suggest an alternative library for video compression that might better suit the requirements ?

  


  <template>&#xA;  <div>&#xA;    <input type="file" accept="video/*" />&#xA;    <video ref="video" controls="controls"></video>&#xA;  </div>&#xA;</template>&#xA;&#xA;<code class="echappe-js">&lt;script&gt;&amp;#xA;import { FFmpeg } from &amp;#x27;@ffmpeg/ffmpeg&amp;#x27;;&amp;#xA;&amp;#xA;export default {&amp;#xA;  methods: {&amp;#xA;    async handleFileInputChange(event) {&amp;#xA;      const file = event.target.files[0];&amp;#xA;      if (!file) return;&amp;#xA;&amp;#xA;      const video = this.$refs.video;&amp;#xA;      const url = URL.createObjectURL(file);&amp;#xA;      video.src = url;&amp;#xA;&amp;#xA;      const inputVideoPath = &amp;#x27;input.mp4&amp;#x27;;&amp;#xA;      const outputVideoPath = &amp;#x27;compressed_output.mp4&amp;#x27;;&amp;#xA;&amp;#xA;      console.log(&quot;Compressing video...&quot;);&amp;#xA;      await this.compressVideo(file, inputVideoPath, outputVideoPath);&amp;#xA;      console.log(&quot;Compression completed.&quot;);&amp;#xA;&amp;#xA;      video.src = URL.createObjectURL(await this.downloadFile(outputVideoPath));&amp;#xA;    },&amp;#xA;    async compressVideo(file, inputVideoPath, outputVideoPath) {&amp;#xA;      const ffmpeg = new FFmpeg();&amp;#xA;      await ffmpeg.load();&amp;#xA;&amp;#xA;      // Writing the input file to the FFmpeg file system&amp;#xA;      await ffmpeg.writeFile(inputVideoPath, file);&amp;#xA;&amp;#xA;      // Execute FFmpeg command for compression&amp;#xA;      await ffmpeg.exec([&amp;#x27;-i&amp;#x27;, inputVideoPath, &amp;#x27;-vcodec&amp;#x27;, &amp;#x27;libx264&amp;#x27;, &amp;#x27;-crf&amp;#x27;, &amp;#x27;28&amp;#x27;, outputVideoPath]);&amp;#xA;    },&amp;#xA;    async downloadFile(filePath) {&amp;#xA;      const ffmpeg = new FFmpeg();&amp;#xA;      await ffmpeg.load();&amp;#xA;&amp;#xA;      // Read the compressed file from FFmpeg file system&amp;#xA;      const data = await ffmpeg.readFile(filePath);&amp;#xA;&amp;#xA;      return new Blob([data.buffer], { type: &amp;#x27;video/mp4&amp;#x27; });&amp;#xA;    }&amp;#xA;  }&amp;#xA;};&amp;#xA;&lt;/script&gt;&#xA;&#xA;&#xA;

  Trying to merge two audio files into a single video at specific offset and duration

  


  What I tried

  


  checked previous stack overflow questions and answers, no one matched my requirements, below is the command i tried

  


  ffmpeg -i 5a54b260-f8a0-11ee-99e0-2d7afd1305f3.mp4 \
   -i 62d24fb0-f8a0-11ee-99e0-2d7afd1305f3.wav \
   -i 76cf3190-f8a0-11ee-99e0-2d7afd1305f3.wav \
   -filter_complex "[1:a]adelay=0|0,atrim=0:18[a1trimmed]; \
                    [2:a]adelay=20000|20000,atrim=0:10[a2trimmed];\
                    [a1trimmed][a2trimmed]amix=inputs=2[aout]" \
   -map 0:v -map "[aout]" -c:v copy -c:a aac -shortest output.mp4


  


  Expected output

  


  Video with both the audios( 62d24fb0-f8a0-11ee-99e0-2d7afd1305f3.wav, 76cf3190-f8a0-11ee-99e0-2d7afd1305f3.wav) first audio start at video start and last for 18 seconds then second audio start at 20 seconds and last for 10 seconds.

  


  What I am getting

  


  output mixes only first audio

  


  Any help appreciated.

  


• No such file or directory : 'ffmpeg' in Django/Docker

  6 avril 2024, par tthheemmaannii

  I run my Django code in Docker. I run transcription software that requires ffmpeg to function. However I've been getting the error [Errno 2] No such file or directory: 'ffmpeg' whenever I try to run my code.

  


  Here's my views.py :

  


  def initiate_transcription(request, session_id):
    ...
                with open(file_path, 'rb') as f:
                    path_string = f.name
                    transcript = transcribe_file(path_string,audio_language, output_file_type)

   ...
