Assembling frames into a video in Node.js using fluent-ffmpeg [closed]
14 novembre 2024, par AndreiI have the original video and it's modified frames in a folder. Now I want to assemble the modified frames into a new video. I also want to take the audio from the original video and add it to the new video.


My latest code is this using fluent-ffmpeg. But it's not working.


await new Promise((resolve, reject) => {
 ffmpeg(path.join(processedFramesDir, "frame-%d.png"))
 .inputOptions(["-framerate 30", "-start_number 1"])
 .input(videoPath)
 .outputOptions([
 "-c:v",
 "libx264",
 "-c:a",
 "copy",
 "-shortest",
 "-r",
 "30",
 "-pix_fmt",
 "yuv420p",
 ])
 .outputOptions(["-map 0:v:0", "-map 1:a:0"])
 .save(outputVideoPath)
 .on("start", (commandLine) => {
 console.log("FFmpeg command: " + commandLine);
 })
 .on("stderr", (stderrLine) => {
 console.log("FFmpeg stderr: " + stderrLine);
 })
 .on("end", resolve)
 .on("error", (err, stdout, stderr) => {
 console.error("Error assembling video:", err);
 console.error("FFmpeg stderr:", stderr);
 reject(err);
 });
});


I get this error even though the frames exist and they are valid pngs :
