Description Jonathan Miles 2016-09-01 09:36:29 UTC 
Building a recent gst-plugins-base (fb9bddd81e08925b329430a0ede9f8e2ef8a0bc5) fails with:

orcc --compat 0.4.23 --implementation --include glib.h -o tmp-orc.c gst-libs/gst/video/video-orc.orc
| ORC: ERROR: orc-0.4.23/orc/orcbytecode.c(251): bytecode_append_int(): assertion failed: value >= 0
| In function video_orc_convert_I420_BGRA:
| error: variable "(null)" used before being written
| In function video_orc_convert_I420_ARGB:
| error: variable "(null)" used before being written
| Failed to compile no orc for 'video_orc_convert_I420_BGRA'
| Failed to compile backup code for 'video_orc_convert_I420_BGRA'

The offending instruction appears to be 'x4 addb argb, x, c4128', which was introduced in: a12f51c video-converter: add more fastpaths for I420 -> RGB
  
Upgrading to orc 0.4.25 fixes the problem.

Should be one of the .24 changes that is needed here. Thanks for reporting.
