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

    12 octobre 2023, 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

 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 !

    


  • FFMPEG cannot encode .MP4 to usable .Y4M RAW video : "Operation not permitted"

    26 janvier 2020, par Ham789

    I am running ffmpeg version 4.2.2 on macOS Sierra and I cannot decode a RAW video.

    First I create the .Y4M video :

    ffmpeg -y -i inputfolder/GH012088.MP4 temp_raw_video.Y4M

    Then I try to input it to ffmpeg :

    ffmpeg -i temp_raw_video.Y4M

    However I get the following error in the terminal : temp_raw_video.Y4M: Operation not permitted

    I have checked the permissions for the ’temp_raw_video.Y4M’ file and I have both read and write permissions.

    I have tried the above with .MOV videos from an iPhone and it works fine.

    The problem seems to be with the .MP4 videos I am trying to convert. These videos were taken with a GoPro camera.

    What is going on here ? Please see the GH012088.MP4 file info below :

    • HDR video after creating bt2020 + smpte2084 video using nvidia hardware accelerator. (I’m studying to make HDR videos. I’m not sure if this is right.)

    How can I make a video using ffmpeg hevc_nvenc and have it play on TV ?


    Things i’ve done

    Here’s what I’ve researched about why it doesn’t work.
    - The header information is not properly included in the resulting video file. So I used a program called nvhsp to add SEI and VUI information inside the video. See below for the commands and logs used.

    nvhsp is open source for writing VUI and SEI bitstrings in raw video. nvhsp link

    # make rawvideo for nvhsp
    $  ffmpeg -vsync 0 -hwaccel cuvid -hwaccel_device 0 -c:v h264_cuvid \
    -i /data/input.mp4 -t 10 \
    -filter_complex "[0:v]hwdownload,format=nv12,\
    format=yuv420p,scale=iw*2:ih*2" \
    -gpu 0 -c:v hevc_nvenc -f rawvideo output_for_nvhsp.265

    # use nvhsp
    $ python nvhsp.py ./output_for_nvhsp.265 -colorprim bt2020 \
    -transfer smpte-st-2084 -colormatrix bt2020nc \

    Goal

    • I want to generate matadata normally when encoding a video through hevc_nvenc.

    • I want to create a video through hevc_nvenc and play HDR Video on smart tv with 10bit color depth support.


    Additional

    • Is it normal for ffmpeg hevc_nvenc not to generate metadata in the resulting video file ? or is it a bug ?

    • Please refer to the image below. (*’알 수 없음’ meaning ’unknown’)

      • if you need more detail file info, check this Gist Link (by ffprobe)
        hevc_nvenc metadata
    • However, if you encode a file in libx265, the attribute information is entered correctly as shown below.

      • if you need more detail file info, check this Gist Link
        libx265 metadata

    However, when using hevc_nvenc, all information is missing.
