I have a directory with randomly named png files (`a.png b.png c.png`) I
want to stitch together in a particular order.
When the names follow a specific format I use:
ffmpeg -r 4 -i image-%07d.png -c:v libx264 -r 4 -pix_fmt yuv420p out.mp4
and it works well. But when the names are random I tried:
I tried:
ffmpeg -r 4 -i a.png b.png c.png -c:v libx264 -r 4 -pix_fmt yuv420p
out.mp4
but it outputs a video with `a.png` only; I also tried:
cat C:\Users\trinker\Desktop\raw3*.png | ffmpeg -f image2pipe -r 1
-vcodec png -i - -vcodec libx264 out.mp4
I'd really like to specify the order manually as I attempted with my first
attempt.
First attempt output:
C:\Users\trinker\Desktop\raw3>ffmpeg -r 4 -i a.png b.png c.png -c:v
libx264 -r 4
-pix_fmt yuv420p outty.mp4

[image2pipe @ 02a60900] Could not find codec parameters for stream 0
(Video: png): unspecified size
Consider increasing the value for the 'analyzeduration' and 'probesize'
options
pipe:: could not find codec parameters
I'm on Windows 7 if it makes a difference.
