I think this is related to the new build system but can't be sure. Using VDPAU_DRIVER=r600 works fine but VDPAU_DRIVER=softpipe fails with - libvdpau_softpipe.so: cannot open shared object file: No such file or directory The lib is built and present, though. -rwxr-xr-x 1 root root 1.8K Jan 31 13:01 libvdpau_softpipe.la lrwxrwxrwx 1 root root 26 Jan 31 13:01 libvdpau_softpipe.so -> libvdpau_softpipe.so.1.0.0 lrwxrwxrwx 1 root root 26 Jan 31 13:01 libvdpau_softpipe.so.1 -> libvdpau_softpipe.so.1.0.0 -rwxr-xr-x 1 root root 27M Dec 19 23:28 libvdpau_softpipe.so.1.0 -rwxr-xr-x 1 root root 30M Jan 31 13:01 libvdpau_softpipe.so.1.0.0 As you can see due to the change of name I still have an old pre automake version of the driver. If I change the links to point to that the above command works. Looking at old and new with ldd the only difference (apart from ../) is that the new lib has libdrm.so.2 whereas the old doesn't. andy [ ~ ]$ ldd /usr/lib/vdpau/libvdpau_softpipe.so.1.0.0 | sort libc.so.6 => /lib/libc.so.6 (0x00007f7faa1f0000) libdl.so.2 => /lib/libdl.so.2 (0x00007f7faab8a000) libdrm.so.2 => /usr/lib/../lib/libdrm.so.2 (0x00007f7fab1be000) libgcc_s.so.1 => /usr/lib/../lib/libgcc_s.so.1 (0x00007f7fa9fdb000) /lib/ld-linux-x86-64.so.2 (0x00007f7fadc49000) libm.so.6 => /lib/libm.so.6 (0x00007f7faa596000) libpthread.so.0 => /lib/libpthread.so.0 (0x00007f7faad8f000) librt.so.1 => /lib/librt.so.1 (0x00007f7faafab000) libstdc++.so.6 => /usr/lib/../lib/libstdc++.so.6 (0x00007f7faa88c000) libvdpau.so.1 => /usr/lib/../lib/libvdpau.so.1 (0x00007f7fac343000) libX11.so.6 => /usr/lib/../lib/libX11.so.6 (0x00007f7fabbf6000) libX11-xcb.so.1 => /usr/lib/../lib/libX11-xcb.so.1 (0x00007f7fabf30000) libXau.so.6 => /usr/lib/../lib/libXau.so.6 (0x00007f7fab5d0000) libxcb-dri2.so.0 => /usr/lib/../lib/libxcb-dri2.so.0 (0x00007f7fab9f2000) libxcb.so.1 => /usr/lib/../lib/libxcb.so.1 (0x00007f7fab7d3000) libXdmcp.so.6 => /usr/lib/../lib/libXdmcp.so.6 (0x00007f7fab3cb000) libXext.so.6 => /usr/lib/../lib/libXext.so.6 (0x00007f7fac132000) linux-vdso.so.1 (0x00007fff4193f000) andy [ ~ ]$ andy [ ~ ]$ andy [ ~ ]$ ldd /usr/lib/vdpau/libvdpau_softpipe.so.1.0 | sort libc.so.6 => /lib/libc.so.6 (0x00007fb749e68000) libdl.so.2 => /lib/libdl.so.2 (0x00007fb74b229000) libgcc_s.so.1 => /usr/lib/libgcc_s.so.1 (0x00007fb74a20d000) /lib/ld-linux-x86-64.so.2 (0x00007fb74cb33000) libm.so.6 => /lib/libm.so.6 (0x00007fb74a929000) libpthread.so.0 => /lib/libpthread.so.0 (0x00007fb74b42d000) librt.so.1 => /lib/librt.so.1 (0x00007fb74a721000) libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0x00007fb74a423000) libvdpau.so.1 => /usr/lib/libvdpau.so.1 (0x00007fb74b025000) libX11.so.6 => /usr/lib/libX11.so.6 (0x00007fb74991c000) libX11-xcb.so.1 => /usr/lib/libX11-xcb.so.1 (0x00007fb74ae24000) libXau.so.6 => /usr/lib/libXau.so.6 (0x00007fb7494fb000) libxcb-dri2.so.0 => /usr/lib/libxcb-dri2.so.0 (0x00007fb74ac20000) libxcb.so.1 => /usr/lib/libxcb.so.1 (0x00007fb7496fe000) libXdmcp.so.6 => /usr/lib/libXdmcp.so.6 (0x00007fb7492f5000) libXext.so.6 => /usr/lib/libXext.so.6 (0x00007fb749c57000) linux-vdso.so.1 (0x00007fff6d452000)

(In reply to comment #1) > Try running under strace to see what's going wrong. Below is what happens - I don't know why - it opens /usr/lib/vdpau OK but then there are a bunch of fails and it ends up trying /lib and /usr/lib. open("/usr/lib/vdpau/libvdpau_softpipe.so.1", O_RDONLY|O_CLOEXEC) = 6 read(6, "\177ELF\2\1\1\3\0\0\0\0\0\0\0\0\3\0>\0\1\0\0\0\200\350\32\0\0\0\0\0"..., 832) = 832 fstat(6, {st_mode=S_IFREG|0755, st_size=31041050, ...}) = 0 mmap(NULL, 24122432, PROT_READ|PROT_EXEC, MAP_PRIVATE|MAP_DENYWRITE, 6, 0) = 0x7fc6e4b34000 mprotect(0x7fc6e5cef000, 2093056, PROT_NONE) = 0 mmap(0x7fc6e5eee000, 475136, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_FIXED|MAP_DENYWRITE, 6, 0x11ba000) = 0x7fc6e5eee000 mmap(0x7fc6e5f62000, 2962496, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_FIXED|MAP_ANONYMOUS, -1, 0) = 0x7fc6e5f62000 close(6) = 0 open("/usr/lib/../lib/tls/x86_64/libstdc++.so.6", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory) stat("/usr/lib/../lib/tls/x86_64", 0x7fff67a3fd10) = -1 ENOENT (No such file or directory) open("/usr/lib/../lib/tls/libstdc++.so.6", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory) stat("/usr/lib/../lib/tls", 0x7fff67a3fd10) = -1 ENOENT (No such file or directory) open("/usr/lib/../lib/x86_64/libstdc++.so.6", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory) stat("/usr/lib/../lib/x86_64", 0x7fff67a3fd10) = -1 ENOENT (No such file or directory) open("/usr/lib/../lib/libstdc++.so.6", O_RDONLY|O_CLOEXEC) = 6 read(6, "\177ELF\2\1\1\3\0\0\0\0\0\0\0\0\3\0>\0\1\0\0\0\360\221\5\0\0\0\0\0"..., 832) = 832 fstat(6, {st_mode=S_IFREG|0755, st_size=5730036, ...}) = 0 mmap(NULL, 3134384, PROT_READ|PROT_EXEC, MAP_PRIVATE|MAP_DENYWRITE, 6, 0) = 0x7fc6e4836000 mprotect(0x7fc6e4916000, 2093056, PROT_NONE) = 0 mmap(0x7fc6e4b15000, 40960, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_FIXED|MAP_DENYWRITE, 6, 0xdf000) = 0x7fc6e4b15000 mmap(0x7fc6e4b1f000, 82864, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_FIXED|MAP_ANONYMOUS, -1, 0) = 0x7fc6e4b1f000 close(6) = 0 open("/usr/lib/../lib/libgcc_s.so.1", O_RDONLY|O_CLOEXEC) = 6 read(6, "\177ELF\2\1\1\0\0\0\0\0\0\0\0\0\3\0>\0\1\0\0\0\20(\0\0\0\0\0\0"..., 832) = 832 fstat(6, {st_mode=S_IFREG|0644, st_size=486560, ...}) = 0 mmap(NULL, 2182520, PROT_READ|PROT_EXEC, MAP_PRIVATE|MAP_DENYWRITE, 6, 0) = 0x7fc6e4621000 mprotect(0x7fc6e4636000, 2093056, PROT_NONE) = 0 mmap(0x7fc6e4835000, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_FIXED|MAP_DENYWRITE, 6, 0x14000) = 0x7fc6e4835000 close(6) = 0 mprotect(0x7fc6e4b15000, 32768, PROT_READ) = 0 open("/etc/ld.so.cache", O_RDONLY|O_CLOEXEC) = 6 fstat(6, {st_mode=S_IFREG|0644, st_size=43792, ...}) = 0 mmap(NULL, 43792, PROT_READ, MAP_PRIVATE, 6, 0) = 0x7fc6eda39000 close(6) = 0 open("/lib/libvdpau_softpipe.so", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory) open("/usr/lib/libvdpau_softpipe.so", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory) munmap(0x7fc6eda39000, 43792) = 0 write(2, "Failed to open VDPAU backend lib"..., 109Failed to open VDPAU backend libvdpau_softpipe.so: cannot open shared object file: No such file or directory
