• Pyinstaller exe works halfway on another computer

  21 octobre 2022, par At Bay

  I created an exe using pyinstaller. I did this by doing the following :

  


  pyinstaller cliptranscript.py


  


  When I run it on another computer, it's works partially. The code starts by asking the user for some arguments, after those inputs I get this error :

  


  Enter directory of wav files: C:\Users\myname\Downloads\&#xA;Enter clip start (seconds): 0&#xA;Enter desired clip length (seconds): 5&#xA;Traceback (most recent call last):&#xA;  File "cliptranscript.py", line 134, in <module>&#xA;  File "cliptranscript.py", line 47, in ffmpeg&#xA;  File "subprocess.py", line 503, in run&#xA;  File "subprocess.py", line 971, in __init__&#xA;  File "subprocess.py", line 1440, in _execute_child&#xA;FileNotFoundError: [WinError 2] The system cannot find the file specified&#xA;[13304] Failed to execute script &#x27;cliptranscript&#x27; due to unhandled exception!&#xA;</module>

  


  I'm using ffmpeg and the libraries os, subprocess, datetime, speech_recognition, and xlsx writer.

  


• Receive rtp (opus) stream from ffmpeg on other computer with VLC

  27 juin 2015, par Friendlyghost89

  I am currently trying to get an opus stream to play on a separate computer using VLC.

  Currently the setup is as follows :

  Odroid-U2 running ffmpeg to capture audio and send as rtp opus stream to remote computer....
  command used : ffmpeg -f alsa -ac 1 -i hw:0 -acodec libopus -ab 32k -ac 1 -f rtp rtp ://192.168.0.115:2032

  the remote computer (on same local network) is at 192.168.0.115
  the Odroid is at 192.168.0.124

  If i use libmp3lame in libopus’s place then the stream will run through without a problem and will not prompt the fact that it requires sdp....

  VLC output on remote computer :

  SDP required: A description in SDP format is required to receive the RTP stream. Note that rtp:// URIs cannot work with dynamic RTP payload format (97).

  If i use an *.sdp file that I drop into vlc to play the stream it does nothing (no errors and no playback)

  SDP file used :

      SDP:
  
      v=0
  
      o=- 0 0 IN IP4 127.0.0.1

• %a and %%a suddenly don't work in Win 10 cmd and batch file respectively ?

  14 janvier 2017, par cobaltB12

  I was trying to batch convert a folder of .flac to .mp3 using FFMPEG, but when i ran my batch file I got the "%F is unexpected at this time" error, even though i used "%%F" in the batch file. To test what was really the problem, i proceeded to type variations of %F into cmd directly, but could not get it to work either. Did something change in windows 10 regarding the use of variable names in the for loop ?

  cmd commands I tried :

  C:\Users\yt\Music\Joe Hisaishi (Classical Guitar) - Copy>for "%F" in     (*.flac) echo %F
  
  "%F" was unexpected at this time.
  
  
  
  C:\Users\yt\Music\Joe Hisaishi (Classical Guitar) - Copy>for %F in     (*.flac) echo %F
  
  echo was unexpected at this time.
  
  
  
  C:\Users\yt\Music\Joe Hisaishi (Classical Guitar) - Copy>for "%%F" in     (*.flac) echo %%F
  
  "%%F" was unexpected at this time.
  
  
  
  C:\Users\yt\Music\Joe Hisaishi (Classical Guitar) - Copy>for "%f" in     (*.flac) echo %f
  
  "%f" was unexpected at this time.
  
  
  
  C:\Users\yt\Music\Joe Hisaishi (Classical Guitar) - Copy>for "%g" in     (*.flac) echo %g
  
  "%g" was unexpected at this time.
  
  
  
  C:\Users\yt\Music\Joe Hisaishi (Classical Guitar) - Copy>for "%g" in     ("*.*") echo %g
  
  "%g" was unexpected at this time.
  
  
  
  C:\Users\yt\Music\Joe Hisaishi (Classical Guitar) - Copy>for "%g" in     ("*.*") do echo %g
  
  "%g" was unexpected at this time.

  original batch file for FFMPEG

  cd "\Users\yt\Music\Joe Hisaishi (Classical Guitar) - Copy"
  
  echo in directory "%cd%"
  
  pause
  
  for "%%F" in ("*.flac") do (
  
  echo converting "%%F"
  
  "C:\Users\yt\Downloads\OtherApps\FFMPEG\bin\ffmpeg.exe" -i "%%F"     -codec:a libmp3lame -qscale:a 2 "%%~nF.mp3"
  
  echo del "%%F"
  
  )
  
  cd "%~dp0"
