TPEMRD/2016/Out-of-process decoding
From MozillaWiki
Contents
Introduction
Sometimes Fennec crashes in the decoding backend which is part of Android phone makers' code and we cannot fix it. Sometimes it could be due to out of memory. By making decoding in another process can prevent Fennec from disappearing when crash and even better we can try it again to see if it can be played again. We expect this can reduce crash rate to improve the user experience.
