Frame rate very high for a muxer not efficiently supporting it
24 décembre 2018, par DevDaveI got an error when trying to run the following command with FFMpeg :
-i "file1.mp4" -s 506x406 -b:v 2000k -ar 22050 "file2.mp4"
FFMpeg was stuck converting this video, which was just a 7Mb .mp4 file, for hours and eventually I had to kill the process.
The output error from FFMpeg is as follows :

ffmpeg image sequence from text file not rendering correctly
4 juillet 2018, par RichI’ve been working with ffmpeg and I have got it to work perfectly quite a few times, but as of recent I am running into an issue where all the images from my text file arent used.
My text file looks like -
ffconcat version 1.0
file 'gallery-house-77-west-55th-street-01.jpg'
duration 4.44
file 'img03.jpg'
duration 4.44
file 'inside.png'
duration 4.44
file 'placeholder.png'(amount of files, file names and extensions will always vary)
And I’ve tried several combinations but as of now my ffmpeg function looks like —
ffmpeg -i audio.mp3 -safe 0 -f concat -i paths.txt -c:a copy -c:v libx264 \
-vf "scale=1280:720:force_original_aspect_ratio=decrease,pad=1280:720:(ow-iw)/2:(oh-ih)/2,fps=25,format=yuv420p" -vsync vfr -movflags +faststart -y output.mp4 2>&1');When trying to run it, the video seems to convert but has various weird behaviors - sometimes only the middle file(image) in the list is shown or the first 2 only are shown/rendered.
The audio is playing correctly though.
I’ve tried setting the framerate for the input and I also tried setting it for the output but it leads to more strange behavior.
This is what is echoed when running my above ffmpeg command -

EDIT
After some more debugging I think it may be related to the fact that all the files dont have the same extension. How can I make it so that it doesn’t have to be that way or is that already a default setting and the issue is else where ?
