Incompatible pixel format 'rgb24' for codec 'gif', auto-selecting format 'rgb8' #39
I followed installation instructions exactly, all requirements met, yet I don't think ffmpeg is installed correctly - maybe you are missing a --flag for brew?
ok, here is what step by step to get the ffmpeg work on MAC. This might not be the same case with all but may be with majority hence posting how did I got it working on my machine.
brew install ffmpeg
but when I run the command, I get this error at the last line of logs Incompatible pixel format 'rgb24' for codec 'gif', auto-selecting format 'rgb8' at the last line. 3. And I ended up on this page to find the fix and I tried all the solutions mentioned above but none worked for my case. Then I go ahead and change my command to use 'rgb8' instead of 'rgb24'
Eg. ffmpeg -i in.mov -s 1000x200 -pix_fmt rgb8 -r 10 -f gif - | gifsicle --optimize=3 --delay=3 > out.gif
Yay, it looks worked because that error disappeared and my out.gif is created but here is the catch "its 0 byte file" - no content.
Now I go and read the logs again and I observe the actual issue was at the first line (not highlighted and so was ignored) -bash: gifsicle: command not found
done: brew install gifsicle
all the errors are gone and I get my gif successfully with 'rgb24' (without any need to change the flags i wanted in my command).
clue: read logs from the top, till bottom and fix all warning like errors

I am getting same error. I see out.gif is created correctly.
Here is the command
ffmpeg -i in.mov -s 200x200 -pix_fmt rgb24 -r 10 -f gif - | gifsicle --optimize=3 --delay=3 > out.gif
