  • how to not remove transparency using negate option on png files ffmpeg

    27 mars 2024, par Reilbas

    I'm new to FFMPEG.
To make it simple, I've created a program that applies a negative filter to small images in png format. For some of the images, everything is fine and the transparency is maintained... But for others, FFMPEG converted the transparency to either black or white pixels.

    


    I'm just using the command :
ffmpeg -y -i input.png -vf negate output.png

    


    I downloaded the latest binaries for windows from https://www.gyan.dev/ffmpeg/builds/ (2024/03/25)

    


  • Failed to run the ffmpeg binary : The process "ffmpeg exceeded the timeout of 60 seconds

    6 janvier 2024, par Sufian The Geek

    I 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.

    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.

    


  • FFMPEG - copy the SPECIFED tracks only, ignore all others

    10 janvier 2024, par GDP

    I have some very strange MP4 files that we get regularly for processing created by Wowza. Neither FFMPEG or MEDIAINFO can detect that there are subtitles soft-coded in them, but they ARE there, I can extract them with ccextractor, and when they're played, the captions appear later in the video where the actually start in the timeline.

    


    I've tried every variation of copying with/without re-encoding, but all the answers show how to "omit" the subtitles with -sn such as these :

    


     ffmpeg -i 3078.mp4 -c copy -sn 3078_sn.mp4
 ffmpeg -i 3078.mp4 -c:v libx264 -c:a ac3 -map 0:v:0 -map 0:a:1 3078_sn.mp4
 ffmpeg -i 3078.mp4 -map 0:v:0 -map 0:a:0  -map -0:s -map -0:d  -c copy 3078_sn2.mp4 -y

    The problem seems to be that FFMPEG isn't detecting they're there, and so copies them anyways. My assumption is that they're not stored in the header of the MP4 properly (or however that's done), so get because they're later detect, but weren't omitted when it checked the header (pure guesswork on that).

    


    So, is there a way to copy ONLY the video, regardless of whatEVER tracks may or not be in the file, then do the same for audio, and then merge the two single-track files ?
