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 :

Screen recording with ffmpeg has stuttering [closed]
7 novembre 2024, par Adam LabušI am recording with ffmpeg like so :
ffmpeg -f x11grab -probesize 18M -framerate 30 -video_size 1920x1080 -i :0.0+0,0 -f pulse -i -c:v libx264 -preset ultrafast -c:a aac .mkv

Problem :


Usually at the start the video starts to stutter, sometimes stuttering up to 20 seconds, each frame during this stuttering is shown for 1-5 seconds. Example video : https://drive.google.com/file/d/1uwdaFboCO2qNALgaPC8JD15W64BE3VyY/view?usp=sharing


Diagnostics :


Machine details :


OS: Fedora Linux 41 (Server Edition) x86_64
Host: HP ProDesk 600 G2 DM
Kernel: Linux 6.11.5-300.fc41.x86_64
WM: Openbox (X11)
CPU: Intel(R) Core(TM) i5-6500T (4) @ 3.10 GHz
GPU: Intel HD Graphics 530 @ 1.10 GHz [Integrated]
Memory: 884.62 MiB / 15.49 GiB (6%)
Swap: 0 B / 8.00 GiB (0%)
Disk (/): 5.45 GiB / 14.94 GiB (37%) - xfs


My gpu(20%), cpu (50%), disk utilisation is always in well perfect range - I tried stress testing gpu, ram, cpu and disk while recording and it had no effect on the recording. I tried recording to ramdisk. I always have 10gb ram available. I ran the same command on my laptop (hp 850 g5) and computer and encountered no stuttering at all.


If it matters the machine is running bare Xorg and openbox display manager


I have tried :


- 

- setting fps_mode to cfr - because the frame rate does fluctuate around 29-30 at the start
- setting fps_mode to vfr
- setting fps_mode to passthrough
- setting cfr all the way to 40
- presets veryfast, faster
- increasing thread_queue_size
- async=1

FFMPEG is not working in app service post deployment
1er mars 2024, par Tushar GuptaI using the Xabe.FFmpeg package to generate clips from a video. The code is basically converting a video to multiple clips and it's working fine in my local but whenever I am uploading the code to app service the code is not working.


Stack : .net
App Service OS : Windows


Error :

Code :


private async Task> PrepareVideoClips(CloudBlockBlob sourceVideoBlob, TimeSpan startTime, TimeSpan endTime)
{
 string tempDirectory = Path.Combine(Path.GetTempPath(), Guid.NewGuid().ToString());

 // Create a temporary directory to store clips locally
 Directory.CreateDirectory(tempDirectory);

 // Download the source video
 string sourceVideoPath = Path.Combine(tempDirectory, "sourceVideo.mp4");
 await sourceVideoBlob.DownloadToFileAsync(sourceVideoPath, FileMode.Create);
 FFmpeg.SetExecutablesPath("Controllers\\ffmpeg\\bin\\");
 // Use FFmpegCore to trim the video
 string outputVideoPath = Path.Combine(tempDirectory, "output.mp4");

 await FFmpeg.Conversions.New()
 .AddParameter($"-ss {startTime.TotalSeconds}") // Start time
 .AddParameter($"-i {sourceVideoPath}")
 .AddParameter($"-to {(endTime - startTime).TotalSeconds}") // Duration
 .SetOutput(outputVideoPath)
 .Start();

 // Return a list of file paths for the clips
 return new List<string> { outputVideoPath };
}
</string>

I tried deploying the app service using different OS but still facing the same issue, I also tried using different packages but the result is same.
