• ffmepg concat videos is blocking in a frame

  5 septembre 2020, par عليلو احمد

  I am using this command to concatinate videos and audio in one single video :

  


  subprocess.run("ffmpeg -stream_loop -1 -f concat -i input.txt -i "+audioPath+" -map 0:v -map 1:a -c:v libx264 -crf 29 -preset slower -shortest -movflags +faststart output.mp4")


  


  And i'm facing a problem, the video sometimes stack in a frame, see Example

  


• Error opening input files : Invalid data found when processing input

  27 mars 2024, par Master's Time

  I am creating disnake music bot. The error is :

  


  [in#0 @ 00000233f8d71500] Error opening input: Invalid data found when processing input
Error opening input file https://www.youtube.com/watch?v=duDUqBtxwXk.
Error opening input files: Invalid data found when processing input


  


  Here is part of my code :

  


  import disnake
import asyncio
from yt_dlp import YoutubeDL
import ffmpeg


YTDL_OPTIONS = {'format': 'bestaudio', 'noplaylist': 'False', 'simulate':'True', 'key':"FFmpegExtractAudio"}
FFMPEG_OPTIONS = {'before_options': '-reconnect 1 -reconnect_streamed 1 -reconnect_delay_max 5', 'options': '-vn'}


async def play_music(inter):
        global YDTL_OPTIONS, FFMPEG_OPTIONS
    print(tm.now().strftime("%H:%M:%S"),"play_music begin")
    id = int(inter.guild.id)
    with YoutubeDL(YTDL_OPTIONS) as ydl:
        info = ydl.extract_info(url, download=False)

    song = {
            'link': 'https://www.youtube.com/watch?v=' + url,
            'thumbnail': 'https://i.ytimg.com/vi/' + url + '/hqdefault.jpg?sqp=-oaymwEcCOADEI4CSFXyq4qpAw4IARUAAIhCGAFwAcABBg==&rs=AOn4CLD5uL4xKN-IUfez6KIW_j5y70mlig',
            'source': info['formats'][0]['url'],
            'title': info['title']
        }   self.vc[id].play(disnake.FFmpegPCMAudio(executable=r"C:\\ffmpeg\\ffmpeg\\bin\\ffmpeg.exe",source=song["source"], **FFMPEG_OPTIONS))
    print(tm.now().strftime("%H:%M:%S"),"play_music end")


  


  I tried to write source = song['source'] instead of source = song['link'], but it didn't seem helpful.

  


• poster adjustment after getting it from video

  30 juin 2016, par Jass

  I am capturing poster from this video https://www.youtube.com/watch?v=wg-kEWsL6Xc using following code. Video can be any, I am just giving example.

  shell_exec('ffmpeg -y  -itsoffset -4  -i "'.base_path().'/assets/videos/'.$file_name.'.mp4" -vcodec mjpeg -vframes 1 -an -f rawvideo -filter:v scale=1170:ih*1170/iw "'.base_path().'/assets/videos/thumbnail/'.$file_name.'.jpg"')

  Width = 1170px,

  Height= 300px (as it is background image so it does not matter)

  But I am facing adjustment problem. Following are my current views

  First : Head is cutting, here I am using css property background : url(’completepath’) center no-repeat ;
  

  Second : Showing black portion on top of head. This is the original image that I am getting from ffmpeg code.

  

  My Question : But I need image like in you tube, you can notice that in all videos we can see top portion of humans without being cutting even black portion is well adjusted.

  Currently I am downloading and testing with youtube videos but in actual job seekers will make their own videos using android/iphone or any camera and will upload on our site.

  so how i can overcome this issue means show image with proper human face and body ?

  thanks in advance.
