• Audio Files downloaded from YouTube-DL are corrupted

  1er juin 2022, par Sushil

  I have written a small piece of code that downloads audios and videos from YouTube using YouTube-DL. Here is my code :

  


  from __future__ import unicode_literals
import youtube_dl

link = input("Enter the video link:")

while True:
    choice = input("Enter a for audio file, v for video file:")
    if choice == "a" or choice == "v":
        break

ydl_opts = {}

if choice == "a":
    ydl_opts = {
        'format': 'bestaudio/best',
        'postprocessors': [{
            'key': 'FFmpegExtractAudio',
            'preferredcodec': 'mp3',
            'preferredquality': '192',
        }],
    }
else:
    ydl_opts = {'format':137}
    
with youtube_dl.YoutubeDL(ydl_opts) as ydl:
    info_dict = ydl.extract_info(link, download=False)
    video_title = info_dict.get('title', None)

if choice == "a":
    path = f'D:\\DwnldsYT\\{video_title}.mp3'
if choice == "v":
    path = f'D:\\DwnldsYT\\{video_title}.mp4'

ydl_opts.update({'outtmpl':path})

with youtube_dl.YoutubeDL(ydl_opts) as ydl:
    ydl.download([link])


  


  This works fine. I am able to play the downloaded audio. But when I try to read the same audio file, it shows me an error.

  


  Code :

  


  from pydub import AudioSegment

song = AudioSegment.from_mp3("D:\\DwnldsYT\\Cartoon - On & On (feat. Daniel Levi) [NCS Release].mp3")


  


  Output :

  Is this because the audio downloaded is corrupted ? And how to solve this problem ? Any help would be appreciated. Thanks !

  


• Concat two mp4 files with MP4Box error : Bad Parameter [on hold]

  6 février 2014, par user3279646

  I'm trying to concat two mp4 files. But I get an error : Bad Parameter

  Can someone help me with this problem ?

  I'm using de debian packages. On a previously version it worked fine. I moved from a old debian version to the new one and I also had to change the ffmpeg to avconv which I use to create these mp4 files. I also had to change the audio codec to '-acodec aac -strict experimental'

  Kind Regards,
  Marcel

• In FFmpeg, using -filter_complex, how can I overlay and blend at the same time ?

  20 avril 2023, par Kristian Boruff

  My code works to combine three videos, resize the videos to 1920X1080, resize the watermark to the correct size, and then overlays the watermark to the lower left hand side. Then converts to the intended codecs for Youtube.
My question is how do I Blend at the same time using the -filter_complex workflow ?
Currently, I have the following workflow that does everything but set the opacity

  



  ffmpeg -y -i fancy movie.mov -i logo.png -i in.mov -i out.mov -c:v libx264 -crf 18 -b:v 50000k -preset veryfast -tune film -profile:v high -x264opts cabac=1:keyint=16:bframes=2:keyint_min=15 -c:a libvo_aacenc -ab 128K -ar 48000 -filter_complex "[0:0] scale=1920X1080 [main]; [2:0] scale=1920X1080 [start]; [3:0] scale=1920X1080 [end]; [start] [2:1] [main] [0:1] [end] [3:1] concat=n=3:v=1:a=1 [prog]; [1:0] scale=480:90 [wm]; [prog] [wm] overlay=36:main_h-overlay_h-45" fart.mp4


  



  I'm trying to add "blend=all_opacity=0.7" in the last step so the watermark will screen against the background. If I just add

  



  [prog] [wm] overlay=36:main_h-overlay_h-45, blend=all_mode='overlay':all_opacity=0.7" fart.mp4


  



  I get the error, Cannot find a matching stream for unlabeled input pad 1 on filter Parsed_blend_6

  



  If I try a semicolon instead,

  



  [prog] [wm] overlay=36:main_h-overlay_h-45; blend=all_mode='overlay':all_opacity=0.7


  



  I get the error, Cannot find a matching stream for unlabeled input pad 0 on filter Parsed_blend_6 which makes me think that it's expecting something like [input 1] [input 2] blend command [output]. The problem is that I need it to overlay and blend.

  



  I tried simplifying the code to just test if the blend operation was working properly.

  



  ffmpeg -i test.mp4 -i logo.png -filter_complex "[0:0] scale=1920x1080 [wm]; [1:0] scale=1920x1080 [prog], [wm][prog] blend=all_mode='overlay':all_opacity=0.7" fart.mp4


  



  I got the error First input link top parameters (size 1920x1080, SAR 1:1) do not match the corresponding second input link bottom parameters (1920x1080, SAR 243:80)
Failed to configure output pad on Parsed_blend_2

  



  So, in addition to the trouble with combining of filters, I'm also having an issue with resizing the watermark as FFMpeg sees it as a different aspect ratio than the other videos.

  



  This is my second day with FFmpeg, so any help would be appreciated.

  



  I'm currently working with FFMpeg version N-61061-gf34cceb
