The vf_drawtext filter uses the GET_UTF8 macro in multiple locations. Each of these use `continue;` as the error handler. However the documentation for the GET_UTF8 macro states "ERROR should not contain a loop control statement which could interact with the internal while loop, and should force an exit from the macro code (e.g. through a goto or a return) in order to prevent undefined results."
This patch adjusts vf_drawtext to use goto error handlers similar to other locations in ffmpeg. Aaron PS Sorry for having to send again, sent from the wrong address last time, so patchwork didn't pick it up.
