• discord.py nextcord.py It cant read mp3 audio files

  23 février 2023, par hihihi hihihi

  I'm trying to make my discord bot speak some text, but I can't make it stream the generated mp3 audio file. I'm using Nextcord and FFmpeg.

  


  This is the code I run :

  


  @bot.command(name="bottalk")
async def bottalk(ctx, *args):
    text = " ".join(args)
    user = ctx.message.author
    if user.voice != None:
        try:
            vc = await user.voice.channel.connect()

        except:
            vc = ctx.voice_client   

        sound = gTTS(text=text, lang="en", slow=False)  
        sound.save("please read this.mp3")

        if vc.is_playing():
            vc.stop()

        source = await nextcord.FFmpegOpusAudio.from_probe("please read this.mp3", method="fallback")
        vc.play(source)
    else:
        await ctx.send("join vc")    


  


  When I run the code it generates the mp3 audio file but cannot play the audio file. I get this error :

• ffmpeg - over 1000 files into a mp4

  20 octobre 2013, par Fabrizio

  I am using FreeBSD and ffmpeg and I am trying to convert over 1000 files into an mp4. Keep in mind that I am completely NEW to ffmpeg and that in the future I might have up to 3600 images.

  I was thinking that simply executing :

  ffmpeg -i /usr/local/www/tmp/phpFa5LT3/*.jpg -r 2 output.mp4

  would work, but I keep getting

  If I reduce the number of files to just a 100 or so, I can do it without any problems... Do you know what the problem might be ?

• How to play an local video in arbitrary codec and format in browser ? [closed]

  24 septembre 2023, par HanXu

  I am developing a video player in browser to let the user select a local video to play, and want to support as many video formats as possible. I know that in browser a video tag can only play videos in a limited set of codecs, and on desktop libraries like VLC can play literally any videos. I would like to bring that broad compatibility to the browser, but not sure how to achieve it.

  


  One thing come up in my mind is to let the user run a thin client natively, which read the local video and stream it at, say, http://localhost:8080, in some web-friendly codec and format, and in the frontend I use a video with src to be http://localhost:8080.

  


  In the client I think I need to run some ffmpeg command to somehow stream and process the video in real-time. I also run into the libVLC which seems nice, and am not sure which one to use.

  


  Furthermore, I need to enable the user to seek to any arbitrary timestamp, and am not sure if the streaming technic supports it.

  


  I have done some googling, and found a method which first runs a ffmpeg command as

  


  VIDSOURCE="/some/video.mp4"
AUDIO_OPTS="-c:a aac -b:a 160000 -ac 2"
VIDEO_OPTS="-s 854x480 -c:v libx264 -b:v 800000"
OUTPUT_HLS="-hls_time 10 -hls_list_size 10 -start_number 1"
ffmpeg -i "$VIDSOURCE" -y $AUDIO_OPTS $VIDEO_OPTS $OUTPUT_HLS /some/public/video.m3u8


  


  and in the frontend I can use the react-player to play the video like

  


  <reactplayer url="/some/public/video.m3u8"></reactplayer>&#xA;

  


  However, I can not seek to an arbitrary timestamp, and the ffmpeg command creates a lot of .ts files one by one about which I am not sure what is going on. It seems that before it creates a video77.ts, I can not seek to timestamp within that segment.

  


  All in all, I am looking for some solution like

  


  

  


  that supports

  


  

  • playing videos in browsers in as many codecs and formats as possible,

  


  • allowing users to seek to any arbitrary timestamp.

  


  


  Since many native video player like VLC supports it, I believe it can be done. Does anyone have any idea that may help ? Appreciate in advance !
