c# - WPF MediaElement FREEZES when setting Position to end of video -


i implemented simple video player. in it, there mediaelement , slider, among other things. anyway, when slide slider way right , set mediaelement.position end of video, video freezes on last frame of video , not resume or respond pause/play commands until load different video mediaelement.

i put in small hack change position value numbers @ least 20 milliseconds end of video, , problem went away:

if ( _mediaelement.hasvideo &&      _mediaelement.naturalduration.hastimespan &&      (_mediaelement.naturalduration.timespan.totalmilliseconds - e.newvalue) > 20) {      _mediaelement.position = new timespan(0, 0, 0, 0, (int) e.newvalue); }

what don't understand why video freeze on last frame? bug in mediaelement control, or there other way work around problem?

i found post 3 years ago describing seems same problem, , solution updated nvidia driver. have date nvidia driver , still have problem. guess above hack works, seems kinda strange video lock that.

please, check if have unloaded behavior property set close. try setting manual. think close implies unloading video , therefore further actions have no effect.

<mediaelement source="media\numbers.wmv" name="mymediaelement"   width="450" height="250" loadedbehavior="manual" unloadedbehavior="manual" />

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
