• Batch script cannot read file if there is a space

  25 août 2022, par Shahpari

  CD "C:\Input"
for %%a in ("*.*") do "C:\ffmpeg.exe" -i %%a -map 0:v -map 0:a:0 -map 0:s -c:v copy -c:a ac3 -b:a 640K "C:\Out\%%~na.mkv"
pause


  


  if there is no space this script works fine, but if there is a space in file name, the script reads only the first word of the file and throws an error. i tried to add a double quote first %%a. but then the script does not even run.

  


  here is an example file name :
[TEST] ABC test - 99

  


• How to downloaded embedded videos on Instagram that have multiple media network requests ? (ffmpeg / curl)

  21 octobre 2022, par flhu

  I was wondering whether it is still possible to download the stories on Instagram that have multiple media network requests nowadays. Previously, I could simply download them using the Firefox Media Page Info View. This is still possible for some content such as reels or by using ffmpeg / curl. I have posted the network behaviour when I load a story on Instagram and a Reel on Instagram. I could not figure out which of the network requests is the relevant one (assuming it is the request with the biggest size) and when downloading it, the VLC player does not recognise the video.

  


  Instagram Reel Network Request

  


  Instagram Stories Network Request

  


  When using the Firefox Media Page Info View, it is possible to download the content from the reel directly whereas the mp4 media file is greyed out.

  


  I tried to copy the URL from the network request using :

  


  ffmpeg -i  -c copy  


  


  Copying the corresponding curl request but also only works for the Reel where the HTTP response status codes is 206 (Reel) instead of 200 (Story).

  


• FFMPEG fnExtractFrameToJPG to DB sequelize

  4 juillet 2020, par jjplack

  after process the video i would like to pass the first frame screenshot to to db !

  


  I've tried by get the originalname or filename and did not get the exact thumb file

  


  So, i've tried also use fs but, the issue is that after the thumb creation the FFMPEG add the thumb number to identify the frame, and seems impossible to get the same thumb.

  


  Someone can help ?

  


  here is the code

  


  fastify.route({
    method: "POST",
    preHandler: upload.single("video"),

    handler: async function(request, reply) {
      const { Post } = fastify.sequelize;
 

      const fileName = Date.now() + "-" + request.file.originalname;
      const filename = request.file.originalname;

      const thumbName = Date.now() + "-" + "thumb" + ".jpg";
      const videoPath = "./public/uploads/";
      const thumbPath = "./public/thumb/";
      // const thumbFile = thumbPath + request.file.
      // const video_file = fs.createReadStream(request.file.path);

      try {
        const process = new ffmpeg(request.file.path);
        process.then(
          function(video) {
            video.fnExtractFrameToJPG(thumbPath, {
              frame_rate: 1,
              number: 1,
              file_name: filename[0] + "_%s"
            });
            video.setVideoStartTime("00:00:00");
            video.setVideoDuration("00:01:00");
            console.log(video.metadata);
            // FFmpeg configuration
            //console.log(video.info_configuration);
            video.save(videoPath + fileName, function(error, file) {
              if (!error) console.log("Video file: " + file);
       
            });
          },
          function(err) {
            console.log("Error: " + err);
          }
        );
      } catch (e) {
        console.log(e.code);
        console.log(e.msg);
      }

      const post = await Post.create({
        video: fileName,
        title: request.body.title,
      
        thumb: thumbName
      });
      reply.code(201).send(post);
    }
  });
