FFMPEG Flutter - Generating video from images not playing on default android video players
17 février 2023, par Abdullah RiazI'm trying to generate a video from multiple image files in FFMPEG Flutter. I'm using https-gpl package.


ffmpeg_kit_flutter_https_gpl: 5.1.0



I'm using this command.


"-f concat -safe 0 -protocol_whitelist file,http,https,tcp,tls,crypto -i $filePath -stream_loop -1 -i $musicFile -vf 'scale=3840:2880:force_original_aspect_ratio=decrease,pad=3840:2880:(ow-iw)/2:(oh-ih)/2,setsar=1' -r 6 -c:v libx264 -crf 40 -profile:v main -preset veryfast -pix_fmt yuv420p -t $totalTime $outputFilePath"



Where you can clearly see, I'm encoding video in
libx264
withyuv420p
.

The thing is, the video is created successfully and played smoothly on the VLC. But it doesn't show anything on normal/default android video players although it plays the audio.


I've tried multiple things but all failed to run video on default android video players. I've even tried multiple android phones.
What am I doing wrong here ?
