Uploading Reel to Instagram via API error : The video format is not supported
24 juin 2024, par Ben FoxI'm using
FFMPegto create a video with backing audio to upload to Instagram via the Graph API. I've followed the specs here as closely as I can : https://www.facebook.com/business/help/1197310377458196?id=376980407544978 and I've usedffprobeandMediaInfoto try and debug differences between my generated file and the requirements from Meta but every time, I get "Video process failed with error : Unsupported format : The video format is not supported. Please check spec for supported duration format".

I've tried doing binary uploads and supplying a URL via their Resumable Upload protocol with the same result both times.





I've uploaded screenshots from MediaInfo showing the entire breakout of the file and here is the code using the Node package fluent ffmpeg to create it :


await new Promise<void>((resolve, reject) => {
 ffmpeg()
 .size('1080x1920')
 .aspect('9:16')
 .autopad()

 .input(imageFilePath)
 .videoCodec('libx264')
 // .inputFPS(fps)

 .input(audioFilePath)

 .audioCodec('aac')
 .audioChannels(2)
 .audioFrequency(48000)
 .audioBitrate('128k')

 .addOption('-use_editlist', '0')
 .addOption('-movflags', '+faststart')
 .addOption('-crf', '23')

 /* .outputOptions([
 // YUV color space with 4:2:0 chroma subsampling for maximum compatibility with
 // video players
 '-pix_fmt yuv420p',
 ]) */

 // Set the output duration. It is required because FFmpeg would otherwise
 // automatically set the duration to the longest input, and the soundtrack might
 // be longer than the desired video length
 .duration(duration)
 // Set output frame rate
 .fps(fps)

 // Resolve or reject (throw an error) the Promise once FFmpeg completes
 .toFormat('mp4')
 .saveToFile(outputPath)
 .on('end', () => resolve())
 .on('error', (error) => {
 console.log('[render] :: Error', error);
 reject(new Error(error));
 });
});
</void>

Add a fixed size image on a video, regardless of the video width & height FFMPEG [duplicate]
30 juillet 2017, par RitaThis question already has an answer here :
This is my code that that is use is following
$info = pathinfo($file) ; $out = "$info[’dirname’]/ss_$info[’basename’]" ; exec("ffmpeg -i ’".$file."’ -i ’".SS_ROOT."".$ss->settings[’watermark_image’]."’ -filter_complex ’overlay=main_w-overlay_w-10:main_h-overlay_h-10’ ’".$out."’") ;that works very well, but it doesn’t keep the logo aspect ratio. I tried this code on two videos with different resolution and this is the result

Accord.Video.FFMPEG getting error for long video
30 novembre 2022, par wahyuI use Accord.Video.FFMPEG to extract images every 10 frames from a video. Total frames for this video is 38194 frames. First run is good, I can save image every 10 frames but after run of about 38185 frames i got null return from this code
Bitmap bmpBaseOriginal = vReader.ReadVideoFrame();, if I see in the video there is no problem at the end of video.

I do something like this


using (var vReader = new VideoFileReader())
{
 vReader.Open(files[0]);
 TotalFrame = vReader.FrameCount;
 countin = Convert.ToInt32(TotalFrame / Convert.ToDouble(countAsset));
 Fps = vReader.FrameRate.Value; 
 int a = 0;
 for (int i = 0; i < vReader.FrameCount; i++)
 {
 if(i < vReader.FrameCount - 1)
 {
 Bitmap bmpBaseOriginal = vReader.ReadVideoFrame();
 if (i%10 == 0)
 {
 a++;
 bmpBaseOriginal.Save(string.Format("{0}\\{1}.jpeg", dirVideo.FullName, a), ImageFormat.Jpeg);
 }
 bmpBaseOriginal.Dispose();
 }
 else
 {
 a++;
 Bitmap bmpBaseOriginal = vReader.ReadVideoFrame();
 bmpBaseOriginal.Save(string.Format("{0}\\{1}.jpeg", dirVideo.FullName, a), ImageFormat.Jpeg);
 bmpBaseOriginal.Dispose();
 }
 }
 vReader.Close();
}


this problem occurs again on another video if the video has a lot of frames, but no problem if the video has a less frames.


How to solve it ?
