Description

The recent ffmpeg update seems to trigger a build failure with GCC4. The revision before the updates, hrev29533, builds okay.

Using hrev29546: 

/home/andreas/Haiku/haiku/src/add-ons/media/plugins/avcodec/libavcodec/cabac.h: In function 'get_cabac_noinline':
/home/andreas/Haiku/haiku/src/add-ons/media/plugins/avcodec/libavcodec/cabac.h:527: error: PIC register '%ebx' clobbered in 'asm'
/home/andreas/Haiku/haiku/src/add-ons/media/plugins/avcodec/libavcodec/cabac.h: In function 'get_cabac':

in libavcodec/config.h you could try changing HAVE_EBX_AVAILABLE to 0 and let me know what that does to the build.

Yes, this fixes it. Committed in hrev29557. Don't know if the produced avcodec plugin is fully functional, though. At least the GCC4 build is fixed. So I close this ticket.
