• In ffmpeg, how to set "-option reserve_index_space=1k" ?

  1er septembre 2019, par Vibok

  I want to reserve a bit of space for the index in my webm files. reserve_index_space seems to do that, but how do you use it ?

  I tried -option reserve_index_space=1k, but it said :

  Unrecognized option 'option'.
  
  Error splitting the argument list: Option not found

  It’s mentioned here : https://ffmpeg.org/ffmpeg-formats.html#Options-7

  This change has brough more issues than benefits, between compilation

• Pyinstaller "Failed to execute script pyi_rth_pkgres" and missing packages

  11 septembre 2016, par gurnben

  This is my first time posting a question here as most of my questions have already been answered by someone else ! I am working on a GUI application in python and am attempting to use pyinstaller to package it into a single folder and .exe for easier portability. Currently, I am using windows 10 and anaconda3 to manage my python packages. The application relies on tkinter, pillow, numpy, scikit-learn, opencv, ffmpeg, and matplotlib. The application is formatted with a main GUI.py file that creates objects of a number of other files (many of which are stored in a subfolder as this GUI is replacing a command line utility that served the same purpose). The issue I am running into (as you can see in the title) is that the .exe is throwing the error block :

  Traceback (most recent call last) :
  File "site-packages\PyInstaller\loader\rthooks\pyi_rth_pkgres.py", line 11, in
  File "c :\users\gurnben\anaconda3\envs\opencv\lib\site-packages\PyInstaller\loader\pyimod03_importers.py", line 389, in load_module
  exec(bytecode, module.dict)
  File "site-packages\setuptools-20.7.0-py3.5.egg\pkg_resources__init__.py", line 68, in
  File "site-packages\setuptools-20.7.0-py3.5.egg\pkg_resources\extern__init__.py", line 60, in load_module
  ImportError : The ’packaging’ package is required ; normally this is bundled with this package so if you get this warning, consult the packager of your distribution.
  Failed to execute script pyi_rth_pkgres

  When I look at the warn.txt it gives a massive list of missing packages including parts of some packages that are actually in the single folder package.
  I have, however, successfully gotten it to recognize the dll files from opencv and it is not listed among the missing (nor is ffmpeg however I did not see any ffmpeg files in the folder). I had to pass in a custom path to get it to include the opencv files as they are not in anaconda at this time.

  Any hints or ideas for next troubleshooting steps ? I am overly greatful for all of the help you an offer and I can upload any code, files, etc. that would help you diagnose the issue. In the meantime I will continue searching for a solution myself !
