  • Removing / Overlaying logo on mp4 video format with ffmpeg on linux

    13 juillet 2016, par SilverShadow

    I’m trying to remove logo from an .mp4 video format with ffmpeg on linux machine without re-encoding (for preserving the same quality) with the following command :

    ffmpeg -i input.mp4 -vf delogo=x=270:y=190:w=40:h=40 -c:a copy output.mp4

    and it give me the following errors :

    Unrecognized option 'vf'

    then a new error came up :

    Unable to find a suitable output format for 'delogo=x=270:y=190:w=40:h=40'

    ffmpeg always updating and it seems that they change command line arguments alot so any material or tutorial i find online seems to get out-dated quickly

    I review their website documentation but can’t get it to work, I think i’m missing something...?

    so what is the correct command line in linux shell also, how to view or find out exactly the area coordinates to be removed before actually removing logo/overlaying it and keep testing every while

    and how to overlay a solid color in certain area instead of removing logo transparently as well ?

  • How to combine a .mp4 video with a .wav audio with an offset in ffmpeg from command line ?

    15 mars 2014, par minder42

    I've got a TV clip in mp4 format containing audio and video, and an WAV audio_commentary track.

    I've been trying to combine them in ffmpeg and then play it online with a flash player (which can only take h264 format)

    What's the best ffmpeg command to accomplish this ? My inputs are MP4 video, WAV audio, and an offset in seconds, the time the audio commentary starts relative to the start of the mp4 video.

    I tried

    ffmpeg -i input_audio.wav -i input_vid.mp4 -vcodec copy output.mp4

    and

    ffmpeg -vcodec copy -ss offset -i input_audio.wav -i input_video.mp4 output.mp4

    nether of these do what I want and output the video in the h264 format that is good for flash players- Is there a way to do this from command line in ffmpeg ?

  • Discord bot not playing any audio and immediately terminates once joined channel (Python)

    28 novembre 2024, par MrPwnageLegend

    I am trying to create a small discord bot for me and my friends. Currently, I tried several examples online for a music bot using ffmpeg. I added the path to environment variables as well. I simplified the code to make it easier to debug. Below is the code :

    


    voice_client = await msg.author.voice.channel.connect()
print(voice_client.is_playing())
FFMPEG_OPTIONS = {'before_options': '-reconnect 1 -reconnect_streamed 1 -reconnect_delay_max 5','options': '-vn'}
voice_client.play(discord.FFmpegPCMAudio(source="test.mp3", **FFMPEG_OPTIONS))


    


    The moment the bot enters the channel, it displays this on the terminal and nothing else happens :
discord.player ffmpeg process 18792 successfully terminated with return code of 2880417800

    


    I originally tried Youtube videos, but that did not work. So, I tried local files, and that did not work as well. Tried bypassing the ffmpeg path using executable = "C:\\ffmpeg\\ffmpeg.exe", still the same error. Is there some other reasons for the error such as firewalls etc ? I have set the intents to all(). Could that be a problem as well ?
