Or from the command prompt just type youtube-dl. All youtube-dl supported sites. Getting started In Windows save the exe version somewhere in your PATH if you want to run it simply as youtube-dl and run it from the command line. To update, simply call youtube-dl -U, we recommend to do it often. After that, you should be able to call it from the command line as youtube-dl.
I will use youtube-dl in the following examples. Usage instructions are easy. Use youtube-dl followed by a video URL or identifier. The video will be saved to the file foobar. As YouTube. In Linux and other unices, video players using a recent version of ffmpeg can play them.
Those two work under Windows and other platforms, but you could also get a specific FLV player of your taste. If you try to run the program and you receive an error message containing the keyword SyntaxError near the end, it means your Python interpreter is too old, remember that youtube-dl need Python version 2. More usage tips The program is usually invoked as youtube-dl followed by options and the video URLs.
Listing all the options here would make this text too long, so you can run youtube-dl --help and get a summary of them. From that point on you can start experimenting with the different options yourself. The most common ones are -t or -l to include the video title in the file name.
Also, the -o option can specify the output file name and path. It allows special character sequences that can be used as templates to be replaced. See the "Output template" section for more details.
However, it will attempt to use the rtmpdump program, if it's installed in your system, to download these videos. Frequently Asked Questions The Frequently Asked Questions documentation chapter contains answers to some common questions that pop up in my e-mail and in the issue tracker. Be sure to check it before reporting problems. Supported sites youtube-dl can download videos from not only YouTube, but over different services. For a complete list, see the Supported sites pages or execute youtube-dl --extractor-descriptions.
YouTube Video Using the -f option and other related options, you can specify the video format to be downloaded. Add the -F option to see all valid formats. Output template The -o option allows users to indicate a template for the output file names. However, it may contain special sequences that will be replaced when downloading each video. To clarify, that's a percent symbol followed by a name in parenthesis, followed by a lowercase S.
Requirements A computer with one of the following operating systems: Linux Debian 10, or a derivative thereof such as Ubuntu You can install it on your host computer as follows, on Linux , on Mac , or on Windows. If you already plugged it in, remove it and replug it so the newly-installed udev rule can take effect. Then continue to install the PyCoral library. The above command installs the standard Edge TPU runtime for Linux, which operates the device at a reduced clock frequency.
You can instead install a runtime version that operates at the maximum clock frequency. This increases the inferencing speed but also increases power consumption and causes the USB Accelerator to become very hot. If you're not certain your application requires increased performance, you should use the reduced operating frequency. Otherwise, you can install the maximum frequency runtime as follows:.
You cannot have both versions of the runtime installed at the same time, but you can switch by simply installing the alternate runtime as shown above. Running at the maximum operating frequency increases the inferencing speed but also increases power consumption and causes the USB Accelerator to become very hot.
If you're not certain your application requires increased performance, you should type "N" to use the reduced operating frequency. You can change this later by re-running this script. The following section describes how the power throttling works and how to customize the trip points. If you are running on ARM64 platform and receive error messages such as the following when you run an inference You should be able to solve it if you modify your kernel command line arguments to include gasket.
For information about how to modify your kernel command line arguments, refer to your respective platform documentation. For bootloaders based on U-Boot, you can usually modify the arguments either by modifying the bootargs U-Boot environment variable or by setting othbootargs environment variable as follows:. If your device includes U-Boot, see the previous HIB error for an example of how to modify the kernel commands.
The following procedure is necessary only if your system includes a pre-build driver for Apex devices as per the first steps for installing the PCIe driver. Due to a bug, updating this driver with ours can fail, so you need to first disable the apex and gasket modules as follows:.
Verify that the apex and gasket modules did not load by running this:. Now follow the rest of the steps to install the PCIe driver. So first follow these steps: Check your Linux kernel version with this command: uname -r If it prints 4. Once rebooted, verify that the accelerator module is detected: lspci -nn grep a You should see something like this: That's it. Just be sure you use Python 3.
