I create a video from a slideshow using ffmpeg. I have a valid video at the end. VLC plays that video, YouTube also. I want to display the final product directly on twitter.
I checked the recommened specs according to resolution, framerate, aspect ration and size required for Twitter to accept this video. But still when trying to add this video direcectly into Twitter I receive an error that "no video with supported format or MIME-Type found".
Ffmpeg does not display any error or warning.
Arguments:
ffmpeg -f image2pipe -framerate 1 -i pipe:.png -c:v libx264 -crf 21 -r 30 -y "Blathering.noaudio.mp4"
As you can see I create one image per frame (-framerate 1) but create a 30fps output file (-r 30)
The output from ffmpeg looks like this:

The Codec information are the following:
This is pure Images, no audio at this point in the video. Is there a parameter I am missing? IMHO this looks like a very common video file I create there.
