• Ffmpeg : Move a slider "image" over a "background" from 0% to 100% in sync with the audio

  7 février 2014, par Znuff

  I'm trying to create a video using the follwing code :

  `$`ffmpeg -loop 1 -r 5 -i video.png -r 5 -i progress.png -filter_complex "overlay=x='if(gte(t,0), -W+(t)*5, NAN)':y=H-h" -i video.mp3 -acodec copy video.mp4

  I have the following files

  • video.png
    • this is a 1280x720 px still frame that is simply a background with a waveform of the video.mp3 file
  • progress.png
    • this is simply a 1280x100 px semi-transparent image that should simulate an animation (from from 0 to 100% of the width of the video.png file, in order to simulate "fill up" animation.

  My issues are as following :

  • The video is not in sync with the audio. The progress bar is way off, instead of finishing at the end of the song, it just keeps going on and on and on and on...
  • Also... it just keeps going on and on ! I left it create a 1 hour video and it never stopped.

  I know I'm missing something in the filter, but I have no idea how I could fix it.

  Could someone lend me some help ?

• ytdl python "KeyError : formats"

  7 juillet 2022, par Mondumkreisung

  Im trying to make a discord music bot for personal use, since groovy and rythm got shut down.
It's working okay-ish I guess, but im having a problem with ytdl.
typing "-play" and an url is working just like intended, but i cant type "-play 'song name'".
Typing "-play example" gives me this :

  


  [download] Downloading playlist: example
[youtube:search] query "example": Downloading page 1
[youtube:search] playlist example: Downloading 1 videos
[download] Downloading video 1 of 1
[youtube] CLXt3yh2g0s: Downloading webpage
Ignoring exception in command play:
[download] Finished downloading playlist: example
Traceback (most recent call last):
  File "C:\Users\Dennis\PycharmProjects\groovy's true successor\venv\lib\site-packages\discord\ext\commands\core.py", line 85, in wrapped
    ret = await coro(*args, **kwargs)
  File "C:\Users\Dennis\PycharmProjects\groovy's true successor\voice.py", line 53, in play
    url2 = info['formats'][0]['url']
KeyError: 'formats'

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "C:\Users\Dennis\PycharmProjects\groovy's true successor\venv\lib\site-packages\discord\ext\commands\bot.py", line 939, in invoke

    raise CommandInvokeError(exc) from exc
discord.ext.commands.errors.CommandInvokeError: Command raised an exception: KeyError: 'formats'


  


  im fairly new to coding, so im sorry if somethings weird to understand.

  


  okay, so : typing -play with an url works fine, but typing -play with the song name doesnt. its only searching for the first word, downloads the first searchresult and then "crashes".

  


  so "-play Rick Astley - Never Gonna Give You Up" for example only searches for "Rick" and then it says something about KeyError : 'formats'
Here is my code :

  


  @client.command()
async def play(ctx, url):
    channel = ctx.author.voice.channel
    voice = discord.utils.get(client.voice_clients, guild=ctx.guild)
    if voice and voice.is_connected():
        pass
    else:
        await channel.connect()

    ffmpeg_opts = {'before_options': '-reconnect 1 -reconnect_streamed 1 -reconnect_delay_max 5', 'options': '-vn'}
    ydl_opts = {'format': "bestaudio/best", 'default_search': 'auto'}
    vc = ctx.voice_client

    with youtube_dl.YoutubeDL(ydl_opts) as ydl:
        info = ydl.extract_info(url, download=False)
        url2 = info['formats'][0]['url']
        source = await discord.FFmpegOpusAudio.from_probe(url2, **ffmpeg_opts)
        vc.play(source)


  


• Getting small file size from ffmpeg [duplicate]

  20 février 2020, par sukach

  I am not an ffmpeg expert. I am trying to get some movies converted to a smaller DIVX file for a cheap portable DVD player for a family trip. The movies are for my kids so I’m not too concerned about quality.

  The DVD player is a 10.1", 1024x600 screen. It says it supports DIVX/MPEG2 files. It took me a lot of experimentation to get the right ffmpeg settings to even get it to work, but I found another answer that provided a very complex set of parameters that ultimately worked.

  I have converted about 20 movies with this setting and every one results in a file size of 1.1GB. I have tried different file sizes and crf settings and it is the same every time.

  Here is an example. First, the original file :

  Same file size but lower resolution.

  Any ideas on what the best settings to achieve my goal ?
