8 septembre 2020, par Joselyn Khor — Analytics Tips, Marketing -
ffmpeg seems to output a video with a wrong codec ?
12 septembre 2020, par asoredI´m using
ffmpeg
with flutter and I create a video from a lot of images. The problem :ffmpeg
seems to not create a video with a right codec or something else.... please check my description below for concrete informations.

First the code parts :


Creating video from images


-r $settings_fps -i $tempPath/img%04d.jpg -vcodec libx264 -y -an -vf "pad=ceil(iw/2)*2:ceil(ih/2)*2" -shortest $tempPath/$videoFileName.mp4


Adding audio to the created video


-i ${finalSong.path} -i $videoPath -c:a aac -shortest $tempPath/$newVideoFileName.mp4


This is my video output from console on creating this video :

flutter: Speichern mit GallerySaver nicht erfolgreich



In general the created video works, but : If i try to save it as video with flutter
gallery_saver
to the device, this video will not saved. Other videos for example works well. But not the created withffmpeg
.

Can you find any reason for this in the ffmpeg output log ? Thank you !
