osx - libpng version incompatibility in fresh installation of IPython -

-

i used this guide install "scientific stack" python (osx 10.9.2, brewed python 2.7.6, ipython 2.0, matplotlib 1.3.1, libpng 1.6.10). looking good.

however, trying run simple plot in ipython's notebook environment --pylab=inline gives me error:

/usr/local/cellar/python/2.7.6/frameworks/python.framework/versions/2.7/lib/python2.7/site-packages/ipython/core/formatters.py:239: formatterwarning: exception in image/png formatter: not create write struct formatterwarning,

and in terminal says: libpng warning: application built libpng-1.5.17 running 1.6.10

i have no other libpng installed far can tell. tried deleting files beginning libpng /usr/local/ , reinstalling everything, no avail. output building matplotlib (pip install matplotlib) contains:

building matplotlib             matplotlib: yes [1.3.1]                 python: yes [2.7.6 (default, mar 16 2014, 15:04:47)  [gcc                         4.2.1 compatible apple llvm 5.1 (clang-503.0.38)]]               platform: yes [darwin]  required dependencies , extensions                  numpy: yes [version 1.8.1]               dateutil: yes [using dateutil version 2.2]                tornado: yes [using tornado version 3.2]              pyparsing: yes [using pyparsing version 2.0.1]                  pycxx: yes [couldn't import.  using local copy.]                 libagg: yes [pkg-config information 'libagg' not                         found. using local copy.]               freetype: yes [version 17.2.11]                    png: yes [version 1.6.10]  optional subpackages            sample_data: yes [installing]               toolkits: yes [installing]                  tests: yes [using nose version 1.3.1]  optional backend extensions                 macosx: yes [installing, darwin]                 qt4agg: yes [installing, qt: 4.8.6, pyqt4: 4.10.4]                gtk3agg: no  [requires pygobject installed.]              gtk3cairo: no  [requires cairo installed.]                 gtkagg: no  [requires pygtk]                  tkagg: yes [installing, version 81008]                  wxagg: no  [requires wxpython]                    gtk: no  [requires pygtk]                    agg: yes [installing]                  cairo: no  [cairo not found]              windowing: no  [microsoft windows only]  optional latex dependencies                 dvipng: no            ghostscript: no                  latex: no                pdftops: no

so seems me matplotlib should compiled against libpng 1.6.10? can me figure out what's going on?

look old header files beginning "png" (png.h, pngconf.h, perhaps others) , remove them.

PHPMotion implementation - URL based videos (Hosted on separate location) -

-
i have implement video collection website users of specific isp. site hosted on public web-server movies hosted on local isp server. user of isp + general visitors can see available movies; isp's users able play them. player on site point url of local machine ( http://192.x.x.x/movies/mymovie.mov ) private class (192.x.x.x) accessible isp user. question: possible phpmotion script? or need custom work. if possible, can please suggest available mods? phpmotion require modifications able handle this. uploading, conversion, thumbnail generation, , playback pretty static in phpmotion. really though, rather modding entire upload , conversion process, if created quick custom form add entries phpmotion database (maybe include thumbnail upload), tweaked playback paths, should go on phpmotion side of things. assume had videos in format player handle (such flv or mp4).

javascript - Using Windows Media Player as video fallback for video tag -

-
getting video play cross platform using example video.js bit of fuss. in days when video should embedded use embed windows media player, work out of box on windows. since it's today old ie on windows doesn't support video tag experimented using windows media player fallback, , work well. what wonder here is, why haven't else solution? have missed something? code small, there's no flash files, cross domain issues or need of server working. works. so before develop further , add custom control , subtitles support wonder say. the code looks this: <video id="myvideo" style="width:640px; height: 360px;" autoplay data-wimpsource="http://esd.volvocars.com/dc/cdn/video/birds-on-a-wire.mp4"> <source src="http://esd.volvocars.com/dc/cdn/video/birds-on-a-wire.mp4" type="video/mp4" /> <source src="http://esd.volvocars.com/dc/cdn/video/birds-on-a-wire.webm" type="video/webm" />
