* lavf: replace AVStream.codec with AVStream.codecparAnton Khirnov2016-02-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, AVStream contains an embedded AVCodecContext instance, which is used by demuxers to export stream parameters to the caller and by muxers to receive stream parameters from the caller. It is also used internally as the codec context that is passed to parsers. In addition, it is also widely used by the callers as the decoding (when demuxer) or encoding (when muxing) context, though this has been officially discouraged since Libav 11. There are multiple important problems with this approach: - the fields in AVCodecContext are in general one of * stream parameters * codec options * codec state However, it's not clear which ones are which. It is consequently unclear which fields are a demuxer allowed to set or a muxer allowed to read. This leads to erratic behaviour depending on whether decoding or encoding is being performed or not (and whether it uses the AVStream embedded codec context). - various synchronization issues arising from the fact that the same context is used by several different APIs (muxers/demuxers, parsers, bitstream filters and encoders/decoders) simultaneously, with there being no clear rules for who can modify what and the different processes being typically delayed with respect to each other. - avformat_find_stream_info() making it necessary to support opening and closing a single codec context multiple times, thus complicating the semantics of freeing various allocated objects in the codec context. Those problems are resolved by replacing the AVStream embedded codec context with a newly added AVCodecParameters instance, which stores only the stream parameters exported by the demuxers or read by the muxers.

* xcbgrab: Provide better names for the y and x optionLuca Barbato2015-02-24
| | | | | | | | | | Incidentally `-y` also collides with avconv global options. Update x11grab to match and document the option. CC: libav-stable@libav.org Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* x11grab: Check the XQueryPointer return valueAntonio Ospite2014-10-04
| | | | | | | | | | | | | | The paint_mouse_pointer() code uses XFixes to retrieve the cursor coordinates, but XFixes gives no information about which screen the pointer is on; this results in always drawing the cursor on the captured screen even if the mouse pointer was on another screen. For example, when capturing from screen 1 (i.e. -f x11grab -i ":0.1") the cursor was being drawn in the captured image even when the mouse pointer was actually on screen 0, which is wrong and visually confusing.

* x11grab: Check XFixesGetCursorImage return valueLuca Barbato2014-10-04

* x11grab: fix a memory leak exposed by valgrindAntonio Ospite2012-03-16
| | | | | | | | | | | | | | | | | | | | | | | | | When using "-f x11grab -i :0.0" valgrind reports a definitely lost memory block with this message: ==31544== 5 bytes in 1 blocks are definitely lost in loss record 1 of 2 ==31544== at 0x4026E68: memalign (in /usr/lib/valgrind/vgpreload_memcheck-amd64-linux.so) ==31544== by 0x4026F17: posix_memalign (in /usr/lib/valgrind/vgpreload_memcheck-amd64-linux.so) ==31544== by 0x60D399A: av_malloc (in /usr/lib/x86_64-linux-gnu/libavutil.so.51.22.1) ==31544== by 0x60D3A70: av_strdup (in /usr/lib/x86_64-linux-gnu/libavutil.so.51.22.1) ==31544== by 0x4A2BE58: ??? (in /usr/lib/x86_64-linux-gnu/libavdevice.so.53.2.0) ==31544== by 0x506D29E: avformat_open_input (in /usr/lib/x86_64-linux-gnu/libavformat.so.53.21.0) ==31544== by 0x400A80: main (in /home/ao2/WIP/am7xxx-play/tests/a.out) The 5 bytes lost are the ones from param = av_strdup(":0.0"), so let's free param in the exit path. Also check the av_strdup() return value. Note: calling av_free(param) even when av_strdup() fails and param is NULL is OK and keeps the code simpler without adding another label to skip av_free().

* configure: Do not unconditionally add -D_POSIX_C_SOURCE to CPPFLAGS.Diego Biurrun2011-05-12
| | | | | | | | | | | | | | | | Adding _POSIX_C_SOURCE to CPPFLAGS globally produces all sorts of problems since it causes certain system functions to be hidden on some (BSD) systems. The solution is to only add the flag on systems that really require it, i.e. glibc-based ones. This change makes BSD systems compile out-of-the-box without the need for adding specific flags manually. It also allows dropping a number of flags set manually on a file-per-file basis, but were only present to work around breakage introduced by the presence of _POSIX_C_SOURCE. Also add _XOPEN_SOURCE to CPPFLAGS for glibc systems. We use XSI extensions in several places already, so it is preferable to define it globally instead of littering source files with individual #defines only needed for glibc.

* Make x11grab cursor drawing suck lessJason Garrett-Glaser2010-11-07
| | | | | | | | | | | | | This new version: 1. Works on 24-bit and 32-bit input, not just 32-bit. 2. Doesn't try to run on 16-bit or 8-bit, instead of outright crashing. 3. Does proper alpha-blending, so cursor shadows look correct. 4. Doesn't swap R and B. Mostly fixes issue 1997. Fixes issue 2056.
