How to get the current frame number in AviSynth? -


in avisynth, there function returns current frame number? if not, how can current frame number?

that's question, quality standards:
goal use in conditional statement it's clear 1 looking @ when comparing encode source. following.

a=import("source.avs") b=ffvideosource("encode.mkv") interleave(a,b) media = ((currentframe % 2 > 0) ? "encode" : "source") subtitle(media)

a simultaneous display of both videos times , frame numbers can created in potplayer or other players support avisynth , can play frame frame. potplayer uses "f" key go forward , "d" key go backward. created having avisynth installed , avs script:

loadplugin("c:\program files (x86)\avisynth 2.5\plugins\ffms2.dll") v1 = ffvideosource("wham!last christmas.mp4") v2 = ffvideosource("wham!last christmas.mp4") stackvertical(v1,v2) showframenumber(scroll=true, x=20, y=40, font="arial", size=24, text_color=$ff0000) showtime(x=82, y=64, font="arial", size=24, text_color=$ff0000) showsmpte(fps=24, x=78, y=88, font="arial", size=24, text_color=$ff0000)

fps=24 added in case fps not exact. v1 , v2 same file here not have , ffms2.dll ffmpeg video loader can use directshowsource , eliminate loading plugin ffms2 as:

v1 = directshowsource("wham!last christmas.mp4") v2 = directshowsource("wham!last christmas.mp4") stackvertical(v1,v2) showframenumber(scroll=true, x=20, y=40, font="arial", size=24, text_color=$ff0000) showtime(x=82, y=64, font="arial", size=24, text_color=$ff0000) showsmpte(fps=24, x=78, y=88, font="arial", size=24, text_color=$ff0000)

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
