When the displayed image is cropped in Y direction (like using panscan controls when playing 4:3 video on a 16:9 monitor), and separated scaling is used, the texture size for the FBO holding the intermediate result was calculated incorrectly. This could lead to artifacts, which were quite apparent with extreme scale factors. Actually, the size of that texture is OK, but the texture shouldn't be used to hold the complete scaled image. Instead, it should be used for the visible part of the image only. Because separate scaling works by scaling in Y direction first, it's still fine to scale the image on the full image width on the first pass. This helps avoiding artifacts on the left/right border of the image when scaling in X direction, as the scaler will try to fetch pixels from beyond the border. (The left border is still kind of fine, but the right border will fetch garbage, unless the texture is strictly sized, or explicit clamping is added to the shader. Too much trouble, so using the full image width is simpler.) Also fix some issues with no-npot mode, which enables use of power-of-2 textures. Maybe this mode isn't really useful anymore (modern hardware is faster with smaller non-power-of-2 textures), but keep it for now. |

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.

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.
