• How to wait until ffmpeg is finished with the conversion

  15 mai 2022, par ThePinkLyna

  Im going nuts with this. The situation is this. I have a picture, I convert that picture into something else using fluentffmpeg and then I want to edit that image then send it. The problem here is that I the conversion stops the script from continuing after is done. And also, the edit part needs to wait until the conversion is done and I don't know how to do that, because it seems that with fluentffmpeg the order of the code doesn't matter.
Here is the script

  


                      
                case 'sticker':
                    
                    
                        const encmedia = isQuotedImage ? JSON.parse(JSON.stringify(mek).replace('quotedM','m')).message.extendedTextMessage.contextInfo : mek
                        const media = await Bether.downloadAndSaveMediaMessage(encmedia)
                        
                        await ffmpeg(`./${media}`)
                            .input(media)
                            
                            .addOutputOptions([`-vcodec`,`libwebp`,`-vf`,`scale='min(320,iw)':min'(320,ih)':force_original_aspect_ratio=decrease,fps=15, pad=320:320:-1:-1:color=white@0.0, split [a][b]; [a] palettegen=reserve_transparent=on:transparency_color=ffffff [p]; [b][p] paletteuse`])
                            .toFormat('webp')
                            .save('./a.webp')
                            .on('start', function (cmd) {
                                console.log(`Started : ${cmd}`)
                            })
                            .on('error', function (err) {
                                console.log(`Error : ${err}`)
                                
                                reply(mess.error.stick)
                            }) 
                            
                            
                    
exec(`webpmux -set exif ./BetherMultiMedia/Marca.exif ./a.webp -o ./a.webp`)
ran = fs.readFileSync(`./a.webp`)
Bether.sendMessage(from, ran, sticker, {quoted: freply})
break


  


  On console I get the latter part first then the conversion, it doesn't make any sense. Help

  


• FFMPEG convert rtp stream to rtmp - bind failed address already in use

  27 août 2020, par Leo

  I setup a server with Janus gateway and using videoroom plugin I'm trying to forward locally the rtp stream using port 5002 for audio and 5004 for video.
This is the videoroom plugin configuration

  



      room-1234: {
        description = "Demo Room"
        secret = "adminpwd"
        publishers = 6
        bitrate = 128000
        fir_freq = 1
        #fir_freq = 10
        audiocodec = "opus"
        videocodec = "vp8"
        #videocodec = "h264"
        record = false
        #rec_dir = "/path/to/recordings-folder"
}


  



  After the RTP forward I would like to convert the video to rtmp to get the video remotely using OBS Studio and I set up an nginx server with rtmp plugin. Using ffmpeg I'm trying to make this conversion and I created the sdp file with this content :

  



  v=0
o=- 0 0 IN IP4 127.0.0.1
s=RTP Video
c=IN IP4 127.0.0.1
t=0 0
a=tool:libavformat 58.29.100
m=audio 5002 RTP/AVP 111
a=rtpmap:111 OPUS/48000/2
m=video 5004 RTP/AVP 100
a=rtpmap:100 VP8/90000
a=fmtp:100


  



  And then I launched the command

  



  ffmpeg -protocol_whitelist rtp,udp,file -loglevel trace -analyzeduration 300M -probesize 300M -i config.sdp -c:v copy -c:a aac -ar 16k -ac 1 -preset ultrafast -tune zerolatency rtmp://127.0.0.1/live/1234


  



  But I got back the error bind failed address already in use. Below the complete output

  I did a lot of searches and tries but I'm really not able to figure out what's wrong. Could you please help me to understand the error ?

  



  Thank you !

  


• How to input an audio file, generate video, split, crop and overlay to output a kaleidoscope effect

  29 septembre 2017, par wrrkkksstffrrg

  I need to create an FFMPEG script which reads in an audio file ("testloop.wav" in this example) generates a video from the waveform using the "showcqt" filter , and then crops and overlays the output from that to generate a kaleidoscope effect. This is the code I have so far - the generation of the intial video and the output section work correctly, but there is a fault in the split, crop and overlay section which I cannot trace.

      ffmpeg -i "testloop.wav" -i "testloop.wav" \
  
  -filter_complex  "[0:a]showcqt,format=yuv420p[v]" -map "[v]" \
  
          "split [tmp1][tmp2]; \
  
          [tmp1] crop=iw:(ih/3)*2:0:0, pad=0:ih+ih/2 [top]; \
  
          [tmp2] crop=iw:ih/3:0:(ih/3)*2, hflip [bottom]; \
  
          [top][bottom] overlay=0:(H/3)*2"\
  
  -map 1:a:0 -codec:v libx264 -crf 21 -bf 2 -flags +cgop -pix_fmt yuv420p -codec:a aac -strict -2 -b:a 384k -r:a 48000 -movflags faststart "${i%.wav}.mp4
