Python Distribution Error (TypeError: canonicalize_version() got an unexpected keyword argument 'strip_trailing_zero')

 Last year I cut my teeth at creating a Python package; Dividere

Recently, building the package was encountering an error:

 

 

python3 setup.py sdist bdist_wheel

make: *** [Makefile:26: buildPipPackage] Error 1

Apparently, there was an error introduced in a recent version of setuptools.  A work-around is to downgrade to an older version to temporarily resolve the issue.

 

~/dividere$ sudo pip3 install setuptools==70.0
 
  

 

 

 

 

Extending Video Introduction

 Sometimes it's useful to slow, or extend the introduction of a video.  For example, suppose you're utilizing a slow video transition (like a fade out/in effect) but don't want to miss the beginning frames of the second video.  By extracting the first frame of the video, elongating it to X seconds we can preserve the transition effect without losing video content.

Let's take a peek at how to accomplish this;

$ cat -n Makefile
     1    all: postVideo.mp4
     2   
     3    video.mp4: BigBuckBunny.mp4
     4        ${SH} ffmpeg -i $< -codec copy -strict -2 -t 10 $@
     5   
     6    image.jpg: video.mp4
     7        ${SH} ffmpeg -i $< -vf "select=eq(n\,0)" -q:v 3 $@
     8        ${SH} display $@
     9   
    10    preVid.mp4: image.jpg
    11        ${SH} ffmpeg -loop 1 -i $< -f lavfi -i aevalsrc=0 -t 3 $@
    12   
    13    postVideo.mp4: preVid.mp4 video.mp4
    14    #    ${SH} ffmpeg -i preVid.mp4 -i video.mp4 -filter_complex "[0:v] [0:a] [1:v] [1:a] concat=n=2:v=1:a=1 [vv] [aa]" -map "[vv]" -map "[aa]" $@
    15        ${SH} ffmpeg -i preVid.mp4 -i video.mp4 -filter_complex "[0:v] [0:a] [1:v] [1:a] concat=n=2:v=1:a=1 [vo] [ao]" -map "[vo]" -map "[ao]" $@
    16   
    17    clean:
    18        ${RM} *.jpg
    19        ${SH} find . -name "*.mp4" -not -name "BigBuckBunny.mp4" -delete

The input video (video.mp4) is generated by grabbing the first 10 seconds of BigBuckBunny.mp4; refer lines 3-4

Then, the first frame of the input video (video.mp4) is extracted and saved as image.jpg (ref lines 6-8)

Then, a new introduction video clip is generated by converting the image into a video clip of X seconds; ref lines 10-11).  Note, a null audio track is created to preserve the audio in the outgoing video.

Lastly, a new video is created by concatenating the intro clip with the original clip, the result as a video with extended first frame. 

One other trick worth mentioning with this makefile, I frequently want a clean target to clobber any video files created along the way.  However, you don't want to delete the original source file, this can be accomplished by utilizing a find+not condition; ref line 19.  This proves useful for many projects.

And, just like that, you've got a video with an elongated intro.

Youtube-Dl Broke/Fixing

 'Some folks' use youtube-dl on a regular basis, to pull raw video and create new content.  Early in 2023 it appeared to stop working.  

$ youtube-dl https://www.youtube.com/watch?v=8QWjCzULyNA
[youtube] 8QWjCzULyNA: Downloading webpage
ERROR: Unable to extract uploader id; please report this issue on https://yt-dl.org/bug . Make sure you are using the latest version; see  https://yt-dl.org/update  on how to update. Be sure to call youtube-dl with the --verbose flag and include its complete output.

Forums seemed to imply the issue was known and a fix was in play, so I put my feet up and figured I'd check back in a few weeks.  A month, or two, goes by and reinstallation/retrying didn't seem to resolve.  So I revisited the fix posts and found it referenced a different package/utility so I tried that out.

$ sudo pip3 uninstall youtube-dl

$ sudo pip3 install yt-dlp

$ yt-dlp https://www.youtube.com/watch?v=8QWjCzULyNA

Hope this helps someone else.

Cheers
