#3004(build system:new): OpenCL Version detection broken (at least on OSX)

#3004: OpenCL Version detection broken (at least on OSX) -------------------------------------+------------------------------------- Reporter: | Owner: thilo.borgmann | Status: new Type: defect | Component: build Priority: normal | system Version: | Keywords: opencl unspecified | configure Blocked By: | Blocking: Reproduced by developer: 0 | Analyzed by developer: 0 -------------------------------------+------------------------------------- Summary of the bug: configure accepts any installed version of OpenCL if any is installed. In configure, it seems like the block starting in line 4263 is not executed (not mentioned anywhere in config.log, see config.log.unpatched): {{{ {...} && {...} && { check_cpp_condition "OpenCL/cl.h" "defined(CL_VERSION_1_2)" || check_cpp_condition "CL/cl.h" "defined(CL_VERSION_1_2)" || die "ERROR: opencl must be installed and version must be 1.2 or compatible"; } }}} If I reorder the three blocks for opencl, a version prior to 1.2 is found and rejected properly (see config.log.patched). How to reproduce: 1) Install OpenCL 1.0 or 1.1 2) Run: {{{ ./configure --enable-opencl }}} I can't find a reason why the test is skipped in the unpatched configure and thus I cannot send a patch to really fix it without further assistance. I also don't have a non-Mac machine ready now to test if this is really just a Mac problem. Attached are a patch for the reordering workaround and two corresponding config.log files. -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/3004> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker

#3016: Support fast yuv422 and yuv444 inverse telecine process ---------------------------------------+---------------------------------- Reporter: cehoyos | Owner: Type: enhancement | Status: new Priority: wish | Component: avfilter Version: git-master | Keywords: pullup Blocked By: | Blocking: Reproduced by developer: 0 | Analyzed by developer: 0 ---------------------------------------+---------------------------------- (This was inexplicably requested on mplayer-users) pullup seems to be signficantly faster than fieldmatch but only supports yuv420p, to fix this either a port of filmdint or improving the pullup filter (or speed up fieldmatch) are possible. -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/3016> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker
