Some scripts I made last year to assist with batch-uploading videos to LBRY (accessible at Odysee.com). The intended usage is:

1. Use youtube-dl to download videos to directories in the working directory, each of which contains a video (video.mkv) and video metadata like title, description, tags, and thumbnail, etc. in dedicated files (i.e. title.txt, description.txt, tags.txt, video.jpg, etc.).
2. Create a file dir-list.txt containing a list of all the directories, one for each video to upload.
3. Run lbry-upload-thumbnails.sh to upload the thumbnails to Spee.ch.
4. Create a file upload-dirlist.txt containing a list of all the videos to actually upload (useful in case some of the thumbnails weren't uploaded successfully in step (3), or some of the videos weren't uploaded successfully in step (5) and you're repeating this step).
5. Run lbry-upload-videos.sh to upload the videos to LBRY.

The upload-thumbnails script expects each directory to contain a thumbnail image, either called thumbnail.jpg, video.jpg, or video.webp, in that order of priority. If it's called video.*, the assumption is that this came directly from youtube-dl, so it runs it through FFmpeg just to make sure it's in proper JPEG format rather than WebP (I had issues uploading such unconverted files to Spee.ch). It then uploads the file to Spee.ch using Curl, saving the URL of the uploaded image to thumbnail-url.txt in that directory for later use by the upload-videos script, which does the job using lbrynet stream create.

Note for macOS users: The usage of sed near the end of the upload-thumbnails script is assumed to be GNU sed (as opposed to BSD sed). You can install this as gsed using Brew with brew install gsed, and then change sed to gsed in the script. Alternatively, we could actually parse the JSON fully using something like jq, but that just wouldn't be fun, now, would it? (Also, I didn't know jq existed when I originally wrote this and can't be bothered to change it and introduce another dependency for Linux users.)
