2514	Upstream bugs in xine-lib	alexander@…	blfs-book@…	"This is a continuation of #2476. Three upstream xine-lib bugs were mentioned there:

1) green artifacts on H.264 videos with the internal ffmpeg (fixed in the book by switching to the external ffmpeg, but the fact that the external ffmpeg has to be compiled with --enable-pp --enable-gpl is mentioned nowhere).

2) Broken (and crashing xfmedia, which is not in the book) OpenGL output as a reason to --disable-opengl: xfmedia still crashes. Gxine doesn't crash, but produces incorrect output when using unaccelerated OpenGL (and defaults to this broken output configuration in qemu or other emulators--you can probably reproduce this on a real machine by moving /usr/lib/dri out of the way and restarting X). The distortion with the same testcase file looks like overall greenish background, a ghost image of the blade shifted to the right from the real one, and purple artifacts on the right. Also, scaling is incorrect. The xshm output plugin produces the correct image. So, the --disable-opengl swtich is still a good idea. Maybe it also makes sense to disable other uncommon outputs such as a framebuffer.

3) Incorrect stack alignment causing the external ffmpeg to think that it has been miscompiled: I cannot reproduce this, and assume that it has been fixed upstream, so there is no need to pass --disable-optimizations as of xine-lib 1.1.12."	defect	closed	normal	6.3	BOOK	SVN	low	fixed
