Casting a video stored on a Windows PC to an LG TV

If you have a movie, or other video, located on a PC running Microsoft Windows and wish to view the movie on your LG Electronics TV, which runs the LG webOS operating system, if they are on the same local area network (LAN), you can "cast" the video to the TV.

If the LG TV is visible to other devices on the network, such as the PC, you should see it within "Media Devices" under "Network" in the Windows File Explorer.

Windows network - LG TV

If you have an MPEG-4 (.mp4) or Audio Video Interleave (.avi) file on the PC, you can right-click on video file, then choose "Show more options," and then choose "Cast to Device" at which point you should see the LG TV as a device to which you can stream the video.

Downloading Smithsonian Associates Encore Videos

If you purchase a Smithsonian Associates class, but are unable to watch the class via the Zoom session at the time scheduled for the live presentation, you can usually log into your Smithsonian Associates account and go to "View my Encores recordings" to watch the class up to 72 hours after the live presentation. At "Welcome to Associates Encores," you will see the following:

Many—but not all—live-streamed programs are recorded. We understand it's not always possible to watch a program in real time, and as a courtesy to ticket buyers we are glad to make recordings available within 24 hours after the program has taken place. The recordings can be viewed for up to three days (72 hours) after they become available.

SmithSonian Associates has stated that they don't have sufficient storage space to make the recordings permanently available. If you can't watch the recording within the 3 days it will be available or want to have a permanent copy available for future reference, you can take the steps listed below to download an MP4 file of the recorded presentation.

If you click on the Watch button from your Encores page on the Smithsonian Associates website, you will be taken to a Zoom webpage. You can watch the video from that page, but if you right-click on the video, you will not see any option to save it. So you need to install a browser extension that will enable right-clicks to work on pages where they have been disabled.

Note: the instructions below are specifically for the Brave browser on a Microsoft Windows system, but the procedure for other browsers is likely to be similar.

Sites that can be used to download YouTube, Instagram, Facebook, Twitter, and TikTok videos

Sometimes videos you might wish to view later, or view again, will disappear from online sites. If you would like to store videos on your own system so that you don't need to worry about them disappearing, either removed by personnel associated with the site or the person who posted the content, there are sites that you can go to where you only need to provide Uniform Resource Locators (URLs) to have the site provide you with a download link you can use to store videos on your own system. For YouTube videos, you can use the OffLiberty site. For Instagram videos, you can use the Inflact site, which also allows you to save videos hosted by Facebook, Twitter (now X), and Tiktok. Both sites allow you to save a video on your own system in .mp4 format. Use of both sites is free.

youtube-dl unable to extract uploader id

I installed ytdl-org / youtube-dl from Github to download videos from YouTube to a Linux system with the pip package manager, since youtube-dl is a Python script, using the command pip3 install youtube-dl. But when I tried to download a YouTube video with youtube-dl, I received an error message indicating the script was unable to extract the ID of the uploader of the video and the video was not downloaded.

$ youtube-dl https://www.youtube.com/watch?v=JmSmjDngVXM

$

I verified I had the latest version of the program, 2021.12.17.

$ youtube-dl --version
2021.12.17
$

To obtain further information on the error, I then ran the script with the --verbose option which showed me more details on the error.

The software, which is a command-line program to download videos from YouTube.com and other video sites, is maintained by ytdl-org and, on a Github webpage for the organization, I found issue #32247, ERROR: Unable to extract uploader id, which attributed the error to YouTube recently starting to add that "at sign", i.e., @, to URLs. jgmayer, who posted his comments and the solution just 3 hours before I encountered the problem, posted the following solution:

The solution is to go to the file that you getting the error:
"/usr/local/Cellar/youtube-dl/2021.12.17/libexec/lib/python3.10/site-packages/youtube_dl/extractor/common.py"

Find the following line:

'uploader_id': self._search_regex(r'/(?:channel|user)/([^/?&#]+)', owner_profile_url, 'uploader id') if owner_profile_url else None,

Replace with the following:

'uploader_id': self._search_regex(r'/(?:channel/|user/|@)([^/?&#]+)', owner_profile_url, 'uploader id', default=None),

The poster indicated the relevant file is /usr/local/Cellar/youtube-dl/2021.12.17/libexec/lib/python3.10/site-packages/youtube_dl/extractor/common.py, but there is no /usr/local/Cellar directory on my system and running the script with the verbose option, showed the relevant code is on line 1,794 of /usr/local/lib/python3.6/site-packages/youtube_dl/extractor/youtube.py.

After making the suggested change, I was able to download a YouTube video with the program.

$ youtube-dl https://www.youtube.com/watch?v=JmSmjDngVXM
[youtube] JmSmjDngVXM: Downloading webpage
[download] Destination: Ancient Greek Lesson #1 _ Learn Greek Fast Online-JmSmjDngVXM.mp4

The updated youtube.py that can be used to replace the 2021.12.17 version in /usr/local/lib/python3.6/site-packages/youtube_dl/extractor/youtube.py.

Downloading Panopto videos

To download a video hosted on Panopto, such as a class lecture, you can take the following steps in the Firefox web browser:
  1. Right-click on the video in Panoptoo—you may need to click on the small video in the upper, left-hand side of the window rather than the one on the right side of the window—and select "Inspect Element (Q)." In the "Search HTML" field, type .mp4 and hit Enter—this presumes the video is an MP4 video.
  2. You should see the area in the HTML code where the MP4 file is referenced highlighted. Right-click on the highlighted area and choose "Copy" then "Outer HTML."
  3. Then paste the information copied into the clipboard into Microsoft Notepad or some other text editor, depending on your operating system and preferred editor. You should see the URL for the video listed in the content pasted into the editor. Copy the URL starting with the "https" up through the ".mp4"—don't copy the information after the ".mp4."
  4. Paste the copied URL into a browser tab. You can then right-click on the video in that browser tab and select "Save Video As" to download the video to your local system. You can give the video a more meaningful name than the long string of hexadecimal digits used for the name.

Placing timestamps at ends of lines of a transcript for Panopto videos

After watching lectures for classes that are stored on the Panopto website, I like to save the text listed for a video in the Contents and Captions that Panopto provides in a text file. However, if I copy and paste the text into Windows Notepad or some other text editor, I see the timestamps appear beneath the relevant text on the following line. To address the problem, I paste the text into the Vim editor on a Microsoft Windows system and apply the command v/\d:\d\d\n/s/\n/ / that replaces the end-of-line character at the end of all lines that don't have a timestamp with a space, instead.

Saving a YouTube Video transcript to a text file

When watching YouTube video lectures, I often wish to save the dialog to a text file that I can search. You can obtain a text transcript of the audio for a YouTube video lecture by clicking on the three dots to the right of "Share", which will give you the option to "Open transcript." When you choose that option, you will then see a transcript displayed to the right of the video. But when you copy that text to a text editor, you may see the dialog on separate lines from the accompanying timestamps. You can put each line of dialog on the same line as its timestamp using the regular expression 1,$ s/\(:\d\d\)\n/\1 / within the vi or vim text editors.

Python script to download YouTube videos on Mac OS X

If you wish to download a YouTube video to store locally on your computer, you can do so on a Mac OS X system, and Linux systems, also, using youtuble-dl, a Python script. You can also download a Microsoft Windows exe file from the youtube-dl Download Page. With youtube-dl, you can download videos from YouTube and other sites from a command-line interface (CLI).

For a Mac OS X system, you can obtain the script using the curl utility that is provided with the operating system. You can also use curl on a Linux system, if you have it installed on that system. Alternatively, you can use wget, which isn't provided with the OS X system, but which you may have on a Linux system, if you don't have curl available. To obtain the youtube-dl script using curl on a Mac OS X system, you can open a Terminal window and issue the command sudo curl -L https://yt-dl.org/downloads/latest/youtube-dl -o /usr/local/bin/youtube-dl. That will download the script and place it in the /usr/local/bin directory.
