Failed to run the ffmpeg binary : The process "ffmpeg exceeded the timeout of 60 seconds
6 janvier 2024, par Sufian The GeekI am using FSPOSTER wordpress plugin to share videos on instagram as a reels and story. I have installed wordpress on amazon aws ec2 t2.micro. FsPoster required FFmpeg plugin to work with the videos.


Whenever I share the video, I get error after 60 seconds. There are some videos that are easily getting shared as a reel and story. I looked into the plugin code and changed every single timeout function value to 300 seconds including php.ini file. There are some libraries like symfony in the plugin, I also changed the timeout 60 sec to 300 seconds. Restarted the server and all but still getting the error.




Failed to run the ffmpeg binary : The process "'ffmpeg' -v error -y -i '/opt/bitnami/wordpress/wp-content/uploads/2024/01/videoWater-First-18.mp4' -vf 'crop=w=1280:h=720:x=0:y=0' -metadata:s:v rotate="" -f mp4 -c:v libx264 -preset fast -crf 24 -strict -2 -c:a aac -b:a 96k '/tmp/fs_65994ac0ddf8b.mp4'" exceeded the timeout of 60 seconds.




I am using bitnami wordpress on ec3 aws t2.micro that has 1 vcpu and 1 GB ram. I also switched to 2 vcpu and 8 gb ram but still this timeout issue.

"How can we use Ffmpeg to apply blur, overlay a logo and waveform, and add a border around a video, step by step ? [closed]
1er février 2024, par itsfaisalkhalidWe're looking to enhance a video using Ffmpeg by implementing several effects sequentially. First, we aim to apply a blur effect to the entire video. Then, we want to overlay a logo and a waveform onto the blurred video. Finally, we need to add a border around the entire composition. This step-by-step process requires precise commands and careful consideration of parameters to achieve the desired result effectively.


I utilized Ffmpeg commands to sequentially apply blur, overlay the logo and waveform, and add a border to the video. I expected each effect to be applied in the specified order, resulting in a visually enhanced video with all desired elements. However, I encountered challenges in properly configuring the parameters for each effect, leading to unexpected results such as misaligned overlays or improper blur intensity.

Flutter : How to use "ffmpeg_kit_flutter" to merge videos ?

In "mergeVideos" function the "returnCode" it return value "1" when i look in the package code


getState() async {
 try {
 return _platform
 .abstractSessionGetState(this.getSessionId())
 .then((state) {
 switch (state) {
 case 0:
 return SessionState.created;
 case 1:
 return SessionState.running;
 case 2:
 return SessionState.failed;
 case 3:
 default:
 return SessionState.completed;
 }
 });
 } on PlatformException catch (e, stack) {
 print("Plugin getState error: ${e.message}");
 return Future.error("getState failed.", stack);
 }
}


Which mean its keep running but in my code it does not wait until complete merging


how can i fix that ??!


but i think my problem is in command(concat)



-i /storage/emulated/0/Movies/VID_20240512_115128.mp4 -i /storage/emulated/0/Movies/VID_20240512_115116.mp4 -filter_complex "[0:v][1:v]concat=n=2:v=1:a=0[outv]" -map "[outv]" -y /storage/emulated/0/merged_video_2024513_122719.mp4


(This is my command when i run the code) ??
