What is the correct parameter for ffmpeg cmd line with libopenh264 to
make a video from image snapshots.
I used for example this:
ffmpeg -start_number 1 -framerate 2 -i img_%d.jpg -c:v h264
-profile:v baseline -r 25 -s 208:160 movie.mp4
I've tried:
- various jpeg, png sets of images
- many other variants of cmd with/without -profile, -r, -s, ...
-preset is not recognized ...
LOG shows that proper encoder libopenh264 is recognized.
The error message is:
Error while opening encoder for output stream #0:0 - maybe
incorrect parameters such as bit_rate, rate, width or height
Always this same error for all possible parameter variations.
Appreciate your help,
