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?

maybe you are missing a --flag for brew?

I dunno, cc @kud maybe, I am on Linux

Did you do brew install ffmpeg --with-libass --with-fontconfig?

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

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.

1. brew install ffmpeg

2. 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

3. 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.

4. 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

5. done: brew install gifsicle

6. 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

+1 brew install gifsicle fixed it for me. Thanks @p00j4!
