• 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);
    }
  });


  


• Telegram Bot - Editing Video in Channel Changes Aspect Ratio to Square

  11 octobre 2024, par Shayki Abramczyk

  I'm working on a Telegram bot that processes videos by adding a watermark and then edits the original message to replace the video in a channel post. The issue I'm encountering is that when I edit the message with the new video, the aspect ratio changes, and the video becomes a square, even though the original video is in vertical format.

  


  Here’s a simplified version of the code I’m using to edit the message with the processed video :

  


  video_file = await video.get_file()
print(video_file)
random = randint(0,9999)
input_path = f"input_{user_id}_{random}.mp4"
output_path = f"output_{user_id}_{random}.mp4"
await video_file.download_to_drive(input_path)

loop = asyncio.get_event_loop()
executor = ThreadPoolExecutor()
await loop.run_in_executor(executor, process_video_sync, input_path, output_path, watermark_path, settings)

try:
    if return_file:
        return open(output_path, 'rb')
    if channel:
        chat_id = post.chat_id
        message_id = post.message_id
        caption = post.caption if post.caption else ""
        if settings['has_signature']:
            signature = settings['signature']
        else:
            caption = post.caption_html if post.caption_html else (post.caption or "")
        video_clip = VideoFileClip(output_path)
        await context.bot.edit_message_media(
            chat_id=chat_id,
            message_id=message_id,
            media=InputMediaVideo(media=open(output_path, 'rb'), width=video_clip.w, height=video_clip.h, caption=caption, parse_mode="HTML")
        )
    elif update.message:
        caption = update.message.caption if update.message.caption else ""
        video_clip = VideoFileClip(output_path)
        
        with open(output_path, 'rb') as video_file:
            await update.message.reply_video(
                video=InputFile(video_file),
                caption=caption,
                width=video_clip.w,
                height=video_clip.h,
                supports_streaming=True
            )
except Exception as e:
    logger.error("Error in sending video. Exception Type:", e.args[0][0], "Message:", e.args[0][1])
finally:
    os.remove(input_path)
    os.remove(output_path)


  


  When editing the message in a channel, the video’s aspect ratio changes from vertical to square (if the video is horizonal it's ok). However, if I send the video as a new message, the aspect ratio remains correct.

  


  How can I ensure that when I edit the video in the channel, the aspect ratio stays the same as the original, and doesn’t get cropped or turned into a square ?
