I got this on the android 4.4.2 (API 19) emulator. Can you please let me know if I did anything wrong?

It would be very useful to minimize size of the output file and allow to configure output image size and count of frames. Now, util creates 5-15Mb images, I think it's too much.

PS: Thank you for this project.

Hi,

your project seems very interesting but the way you connect your Android device to the computer that is running RoboGif is somewhat obscure (at least for me). Could you please improve the documentation?

Cheers.

P.

Some devices seem to not report their model name (e.g. my Nexus S / 4.0.4), so generating the list of connected devices fails with a KeyError. I've added a fallback that simply displays (unknown) for the model name, if model key is missing inside the device dictionary.

First and above all, thanks a lot for your code. It is really useful.

There is a use case where I can't use it, when I need to show the user iteraction. Would you please consider adding a "touch" option like the one Android Studio has when recording videos?

There's a forked version of gifsicle called lossygif (https://kornel.ski/lossygif) that allows for reducing GIF file sizes even more than using the original gifsicle optimizations.

gifsicle --lossy=20 -O3 -o out.gif in.gif

Robogif could use lossygif to even further crunch down sizes of generated GIFs. A very convenient feature would be a --max-filesize option, that would tell robogif to continuously increase lossyness, trying get the final file size below that option value. This option can come in handy when a file size restriction is given (e.g. when adding GIF files to GitHub issues).

robogif --max-filesize=10M out.gif
