java - Calculate real-time transfer rate of MediaRecorder while streaming over a socket -


i using mediarecorder capturing user's voice , streaming in amr-wb format on wi-fi socket connection:

mediarecorder.setoutputfile(parcelfiledescriptor.fromsocket(socket).getfiledescriptor());

i want display transfer rate on screen , looking best way implement this. can think of 2 solutions myself:

  • create localsocket-localserversocket loop , transfer data using buffers. add unnecessary delay , increase performance overhead.
  • calculate transfer data based on codec's characteristics. e.g., (size of each sample) * (samples per second). solution not work networks random delays or codecs variable encoding rates.

is there other way?

parcelfiledescriptor.createpipe() create pipe you.

you can write pipe , count bytes read other end before streaming them off aether...

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 ...
