showcase-dl

A parallel downloader to create private backups of embedded vimeo videos, vimeo showcases and vimeo events.

Why does this exist?

The need arose to secure a private backup of a some embedded vimeo showcases.

As it turned out, the almighty yt-dlp did not support the creation of local backups from vimeo showcases (neither vimeo events).

This tool is the result of some initial tinkering to try and automate the extraction of data necessary to download vimeo showcase videos anyway.

This, however, soon turned into perfectionist yak shaving, ending up in a terminal user interface for parallel downloading of all embedded vimeo videos and vimeo showcases on a webpage.

What does it do and how do I use it?

Installation

Currently no prebuilt binaries are provided. To compile the tool, simply get rustup and cargo by following the instructions at rustup.rs.

Then git clone this repository (or download as .zip file and extract), and run cargo build --release in the project folder. Cargo will make sure to download all dependencies from crates.io, install and compile them; then it will compile the app for you.

The finished executable binary will be found at <project folder>/target/release/showcase-dl on Linux or Mac, or at <project folder>/target/release/showcase-dl.exe on Windows.

Note: Windows support is fully speculative and might fail to even compile. Use Linux. 🐧

Usage

After cloning the repository, enter the project directory. Then, compile the project.

cd "<project folder>";
cargo build --release;

Fetch all showcase and simple player clips embedded on a page

To start downloads, run the executable in your terminal. The only required argument is the URL of the page containing the embedded showcases.

./target/release/showcase-dl "<URL of webpage containing embedded videos>"

Fetch a single showcase's, event's or simple player's clip(s)

To start downloads, run the executable in your terminal. The only required argument is the URL of the Vimeo showcase or simple player.

If the showcase or simple player is referer-restricted (only playable on the page it is embedded on), then use the --referer option to pass the embedding page's URL.

./target/release/showcase-dl --referer "<URL of webpage containing embedded videos>" "<URL of showcase or simple player>"

Download progress and quitting

Download progress

You can close the app at any time by pressing either the Q or Esc key, or the combination Ctrl+C.

As long as you do not close the app ahead of time, your videos will be downloaded concurrently, each in their own time.

Partially finished

After all downloads have finished, the app will remain open. This way, you can just go do other stuff, and come back to a nice status overview. Close the app with the Q or Esc key, or the combination Ctrl+C.

Note:

When downloading a Vimeo event or other live stream, then yt-dlp needs a few seconds to mux the downloaded stream into a video file. Therefore, after requesting exit with the Q or Esc key, or the combination Ctrl+C, the app will send an interrupt signal to yt-dlp to initiate the stream muxing. It will then wait for all downloader processes to gracefully quit before shutting down completely.

Passing options to the downloader and extracting audio

After the webpage URL and a double dash (--) you can define additional options, which will be passed straight to the downloader (yt-dlp by default).

This allows you to define video formats:

./target/debug/showcase-dl "<URL of webpage>" -- --audio-multistreams --format "bv[vcodec^=avc1]+ba[acodec^=opus]+ba[acodec^=mp4a]/b"

Or extract audio:

./target/debug/showcase-dl "<URL of webpage>" -- --extract-audio --audio-format "opus/mp3" --keep-video

Debugging

Raising log verbosity

Using the -v[v[v[v]]] verbosity flag or the RUST_LOG environment variable, you can observe runtime information being written to showcase-dl.log.

Errors are always reported.

  • warn: Only errors and warnings.
  • info: Rough progress updates.
  • debug: Fine grained progress updates and regular expression matches.
  • trace: Full dumps of fetched HTML content.

Globally, using the -v CLI verbosity flag

Invoke showcase-dl with more -v[v[v[v]]] for more verbosity:

  • -v is warn.
  • -vv is info.
  • -vvv is debug.
  • -vvvv is trace.

Place the verbosity flag before the webpage URL, especially if using additional downloader options, e.g.:

./target/release/showcase-dl -vvv "<URL>" -- --prefer-free-formats

Selectively, using environment variable

Use the EnvFilter syntax to target specific crates and raise verbosity in a finer grained manner.

Example: To only enable debug logging for showcase-dl itself, but not for its dependencies, set:

RUST_LOG="showcase_dl=debug"

Observing log output

Use a split terminal, or a separate terminal window, to observe the live messages with (Linux, Mac):

tail -f showcase-dl.log

Collecting and viewing structured traces

Use the --otlp-export CLI option to enable OpenTelemetry export. Exported OTLP data may be captured by Jaeger or any other compatible trace collector.

OpenTelemetry traces viewed in Jaeger UI

To collect traces, first start a Jaeger all in one service:

docker run -p 16686:16686 -e COLLECTOR_OTLP_ENABLED=true -p 4318:4318 jaegertracing/all-in-one:latest

Open the Jaeger UI in your browser: http://localhost:16686/search?limit=1500&lookback=1h&service=showcase-dl

Then, start showcase-dl with the --otlp-export option:

RUST_LOG=warn,showcase_dl=trace ./target/release/showcase-dl --otlp-export "<URL>"

You may use the -v CLI verbosity flag or the EnvFilter as detailed above, and as you see fit.

Switching back to Jaeger in your browser window, repeat the prefilled search, then click the search result trace to inspect its tree.

Note that traces are incomplete while the tool is running. Some traces may be misplaced until their parent span has finished. Quit showcase-dl, then repeat the search, to view the most complete trace tree possible.

Custom downloader

To use a custom version of yt-dlp or youtube-dl, pass the path to it via the --downloader option, e.g.:

./target/release/showcase-dl --downloader /path/to/yt-dlp/yt-dlp.sh "<URL>"

Credentials

This little tool is standing on the shoulders of giants.

Disclaimer

This tool has been built to help create legal private backups of your own vimeo videos and showcases.

Make sure you hold the copyright of any material, and tread on safe legal ground according to the country you live in, before you use this tool!

This tool does not itself download any video material. It merely spawns and sheperds processes of yt-dlp.
