Command line video player

The code that is changed is responsible for scaling the video size to display size, so that the resulting video rectangle is letter-boxed inside the display window. This is before panscan calculations, which can actually enlarge the video and make it larger than the display size again. (src_dst_split_scaling() in vo.c takes cares of clipping the video size to window size.) I'm not sure why this rounding is done, as using panscan controls can introduce odd sizes again. The rounding has been part of the code since the initial commit. On the other hand, this rounding can slightly influence the aspect ratio of the displayed image to the worse. It forces the image to be scaled by an additional pixel, without actually correcting the display size into the other direction. Although video sizes are usually at least aligned on 2 (and often more), odd sizes can still happen when playing e.g. anamorphic DVDs. Remove the additional rounding. (Note that we still round the _source_ image position and size when the displayed image is larger than the screen, e.g. when panscan is used. This is needed by some VOs so that the image source rectangle starts on full chroma pixels. Maybe this rounding should be moved to the respective VOs, which includes at least vo_direct3d.) |

mpv ### Overview ======== **mpv** is a movie player based on MPlayer and mplayer2. It supports a wide variety of video file formats, audio and video codecs, and subtitle types. If you are wondering what's different from mplayer2 and MPlayer you can read more about the changes_. Compilation =========== Compiling with full features requires development files for several external libraries. Below is a list of some important requirements. For more information see the output of ``./configure --help`` for a list of options, or look at the list of enabled and disabled features printed after running ``./configure``. If you think you have support for some feature installed but configure fails to detect it, the file ``config.log`` may contain information about the reasons for the failure. Essential dependencies (incomplete list): - gcc or clang - X development headers (xlib, X extensions, libvdpau, libGL, libXv, ...) - Audio output development headers (libasound, pulseaudio) - fribidi, freetype, fontconfig development headers (for libass) - libass - FFmpeg libraries (libavutil libavcodec libavformat libswscale libpostproc) - libjpeg - libquvi if you want to play Youtube videos directly - libx264 if you want to use encoding (has to be explicitly enabled when compiling ffmpeg) Most of the above libraries are available in suitable versions on normal Linux distributions. However FFmpeg is an exception (distro versions may be too old to work at all or work well). For that reason you may want to use the separately available build wrapper (mpv-build_) that first compiles FFmpeg libraries and libass, and then compiles the player statically linked against those. If you are running Mac OSX and using homebrew we provide homebrew-mpv_, an up to date formula that compiles mpv with sensible dependencies and defaults for OSX. Bug reports =========== Please use the `issues tracker`_ provided by GitHub to send us bug reports or feature requests. Contributing ============ For small changes you can just send us pull requests through GitHub. For bigger changes come and talk to us on IRC before you start working on them. It will make code review easier for both parties later on. Contacts ======== You can find us on IRC in ``#mpv-player`` on ``irc.freenode.net`` .. _changes: https://github.com/mpv-player/mpv/blob/master/DOCS/man/en/changes.rst .. _mpv-build: https://github.com/mpv-player/mpv-build .. _homebrew-mpv: https://github.com/mpv-player/homebrew-mpv .. _issues tracker: https://github.com/mpv-player/mpv/issues
