• 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

• Android Stickers on Video using FFmpeg

  Android Stickers on Video using FFmpeg

  Android doesnot have a native support for adding text and watermark to videos, I would like to add stickers and text to videos using ffmpeg while the command for adding text and stickers is based on ffmpeg , the UI would be dependent on the user, the user can drag, scale, rotate, the stickers, text etc, and position them where he wants

  there are many libraries to use for stickers

  like http://stackoverflow.com/a/35739505/3126760

  however the problem is to get the scale, rotation,position of the sticker on the video that we have, which can be the passed on to the ffmpeg command like

  String[] complexCommand2 = {"-y", "-i", videoFilePath, "-i", imagepath, "-filter_complex","[1:v] format=bgra, rotate=30*PI/180:c=none:ow=rotw(30*PI/180):oh=roth(30*PI/180) [rotate];[rotate]scale=50:50[scale];[0:v][scale] overlay=40:10","-codec:a","copy", outputFilePath};

  Is there a opensource project or tutorial that can help me to achieve this
