SCOPE: Affects gentoo users running MythTV on an computer using the Via CLE266 hardware MPEG decoder. Primary users of the Via Epia mini-ITX motherboard family. This one took me a minute to track down, but there is an error in the use of sed to uncomment lines in the file settings.pro (located /var/tmp/portage/mythtv-0.16.20050115/work/mythtv/settings.pro). It should be noted also that the settings.pro included with mythtv-0.16 is non-standard to start with, and not all of the via XvMC lines start out commented out, like they should (to make it like the nvidia XvMC lines). The original calls from the ebuild are (lines 131-140): if use cle266 ; then sed -e 's:#EXTRA_LIBS += -lviaXvMC -lXvMC:EXTRA_LIBS += -lviaXvMC -lXvMC:' \ -i 'settings.pro' || die "enable cle266 sed failed" fi if ! use cle266 ; then sed -e 's:CONFIG += using_xvmc using_xvmc_vld:#CONFIG += using_xvmc using_xvmc_vld:' \ -e 's:DEFINES += USING_XVMC USING_XVMC_VLD:#DEFINES += USING_XVMC USING_XVMC_VLD:' \ -i 'settings.pro' || die "disable VLD XvMC sed failed" fi Should be replaced with: if use cle266 ; then sed -e 's:#CONFIG += using_xvmc using_xvmc_vld:CONFIG += using_xvmc using_xvmc_vld:' \ -e 's:#DEFINES += USING_XVMC USING_XVMC_VLD:DEFINES += USING_XVMC USING_XVMC_VLD:' \ -e 's:#EXTRA_LIBS += -lviaXvMC -lXvMC:EXTRA_LIBS += -lviaXvMC -lXvMC:' \ -i 'settings.pro' || die "enable cle266 sed failed" fi if ! use cle266 ; then # needed because nvidia and cle266 are not compatible sed -e 's:EXTRA_LIBS += -lviaXvMC -lXvMC:#EXTRA_LIBS += -lviaXvMC -lXvMC:' \ -i 'settings.pro' || die "disable VLD XvMC sed failed" fi I tested this ebuild after making these changes, and was able to successfully build mythtv 0.16 with viaXvMC support, and it acted normally (didn't crash as soon as it attempted an XvMC call). deepshag@gmail.com 2005-02-09 07:39:41 0000 Created an attachment (id=50831) Patch to fix the via XvMC support in ebuild mythtv-0.16.20050115.ebuild cardoe@gentoo.org 2005-02-09 23:25:08 0000 Thanks. In CVS. kallamej@gentoo.org 2005-02-10 06:36:22 0000 This fix breaks USE="nvidia -cle266", as the nvidia sed matches also the XvMC_VLD support. It results in the following settings.pro. # XvMC support, modify as necessary. CONFIG += using_xvmc DEFINES += USING_XVMC EXTRA_LIBS += -lXvMCNVIDIA -lXvMC # XvMC_VLD support, modify as necessary. Incompatible with normal XvMC support. CONFIG += using_xvmc using_xvmc_vld DEFINES += USING_XVMC USING_XVMC_VLD ##EXTRA_LIBS += -lviaXvMC -lXvMC Mythtv consequently fails to compile due to xvmc_render.h:13:36: X11/extensions/vldXvMC.h: No such file or directory while compiling vmcvldvideo.c The ! use cle266 case needs to be restored to its previous state. 50831 2005-02-09 07:39 0000 Patch to fix the via XvMC support in ebuild mythtv-0.16.20050115.ebuild patch-mythtv-0.16.20050115-viaXvMC-fix-ebuild text/plain LS0tIG15dGh0di0wLjE2LjIwMDUwMTE1LmVidWlsZAkyMDA1LTAyLTA5IDE2OjM5OjMyLjc0NjUy ODk4NCArMDEwMAorKysgbXl0aHR2LTAuMTYuMjAwNTAyMDkuZWJ1aWxkCTIwMDUtMDItMDkgMTY6 Mzk6MzIuNzcyNTI1MDMyICswMTAwCkBAIC0xMjksMTMgKzEyOSwxNCBAQAogCWZpCiAKIAlpZiB1 c2UgY2xlMjY2IDsgdGhlbgotCQlzZWQgLWUgJ3M6I0VYVFJBX0xJQlMgKz0gLWx2aWFYdk1DIC1s WHZNQzpFWFRSQV9MSUJTICs9IC1sdmlhWHZNQyAtbFh2TUM6JyBcCisJCXNlZCAtZSAnczojQ09O RklHICs9IHVzaW5nX3h2bWMgdXNpbmdfeHZtY192bGQ6Q09ORklHICs9IHVzaW5nX3h2bWMgdXNp bmdfeHZtY192bGQ6JyBcCisJCQktZSAnczojREVGSU5FUyArPSBVU0lOR19YVk1DIFVTSU5HX1hW TUNfVkxEOkRFRklORVMgKz0gVVNJTkdfWFZNQyBVU0lOR19YVk1DX1ZMRDonIFwKKwkJCS1lICdz OiNFWFRSQV9MSUJTICs9IC1sdmlhWHZNQyAtbFh2TUM6RVhUUkFfTElCUyArPSAtbHZpYVh2TUMg LWxYdk1DOicgXAogCQkJLWkgJ3NldHRpbmdzLnBybycgfHwgZGllICJlbmFibGUgY2xlMjY2IHNl ZCBmYWlsZWQiCiAJZmkKIAotCWlmICEgdXNlIGNsZTI2NiA7IHRoZW4KLQkJc2VkIC1lICdzOkNP TkZJRyArPSB1c2luZ194dm1jIHVzaW5nX3h2bWNfdmxkOiNDT05GSUcgKz0gdXNpbmdfeHZtYyB1 c2luZ194dm1jX3ZsZDonIFwKLQkJCS1lICdzOkRFRklORVMgKz0gVVNJTkdfWFZNQyBVU0lOR19Y Vk1DX1ZMRDojREVGSU5FUyArPSBVU0lOR19YVk1DIFVTSU5HX1hWTUNfVkxEOicgXAorCWlmICEg dXNlIGNsZTI2NiA7IHRoZW4gIyBuZWVkZWQgYmVjYXVzZSBudmlkaWEgYW5kIGNsZTI2NiBhcmUg bm90IGNvbXBhdGlibGUKKwkJc2VkIC1lICdzOkVYVFJBX0xJQlMgKz0gLWx2aWFYdk1DIC1sWHZN QzojRVhUUkFfTElCUyArPSAtbHZpYVh2TUMgLWxYdk1DOicgXAogCQkJLWkgJ3NldHRpbmdzLnBy bycgfHwgZGllICJkaXNhYmxlIFZMRCBYdk1DIHNlZCBmYWlsZWQiCiAJZmkKIAo=
