A Web scraper for InfoQ.
InfoQ hosts a lot of great presentations, unfortunately it is not possible to watch them outside of the browser or if you do not have Flash installed. The video cannot simply be downloaded because the audio stream and the slide stream are not in the same media. By downloading the video you only get the audio track and a video of the presenter but you don't get the slide.
infoqscraper allows you to:
- list and search for presentations
- download the resources (video, audio track, slides)
- build a movie including the slides and the audio track from the resources
The project is split in two part; a reusable library and a command line interface. Only Python 2 is currently supported since PIL is not yet available for Python 3.
Infoqscraper releases can be installed using
pip and PyPI.
pip install [--user] infoqscraper
infoqscraper executable will now be available in your path.
infoqscraper [global options] module [module options] command [command options]
This module allows to list, search and download presentation from the website
The following command displays the 20 latest presentations.
infoqscraper presentation list -n 20
You can also search for a specific topic:
infoqscraper presentation list -p agile
By default at most 10 hits are returned and only the latest 80 entries are fetched from the website.
-m options can be used to display more hits or to fetch more entries.
Please be a good web citizen and avoid to set
-m to a very large value. Using a search engine
or the website could be a better idea.
The following command automatically downloads the presentation and creates a movie file
Distributed-Systems-with-ZeroMQ-and-gevent.avi in the current directory.
infoqscraper presentation download Distributed-Systems-with-ZeroMQ-and-gevent
This module allows to manage the disk cache.
Disk cache is disabled by default and is only useful if you plan to hack on
infoqscraper. To avoid fetching
the same resource several time from the server, all fetched resources can be put in cache. This is done by setting
-c global option. The resources are stored in the
The following command show the size of the cache:
infoqscraper cache size
And the clear command allows to wipe the cache
infoqscraper cache clear
