• 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 ?

  


• look for a specific filetype in a directory in php and send it to a different directory after conversion

  12 juin 2019, par flash

  I have a directory in which there is a mp4 file (including other files as well) which I want to convert into mp3 and then send it to different directory. I have used the following command line command to covert into mp3 and its working perfectly fine.

  ffmpeg -i 36031P.mp4 -map 0:2 -ac 1 floor_english.mp3 

  mp4 file is inside in_folder. Using ffmpeg, I want to convert mp4 file into mp3 and send it to out_folder.

  <?php
  
  $dir    = 'in_folder';
  
  $files1 = scandir($dir);
  
  print_r($files1);    /* It lists all the files in a directory including mp4 file*/
  
  ?>

  print_r($files1) lists all the file in a directory including mp4file.

  Problem Statement :

  I am wondering what php code I need to write so that it looks for only mp4 file inside the directory and send it to different directory (let say out_folder) after converting into mp3.

  The pictorial representation of what I want :
