jobro has asked for the wisdom of the Perl Monks concerning the following question:

honorable monks, I am looking for a way to run a video from a perl script, i.e. 'imitating' the click on an arrow symbol of an embedded flash video which would start it. So far I figured out that WWW:Mechanize does not seem to offer this possibility. Ultimately, I would like to run the video and capture the ensuing http traffic (as tcpdump does). Thanks for any comment.

      Thanks for your answer. I used to use your suggestion with rtmpdump before, but now the page in question does no longer serve a mp4-file and does not employ the rtmp protocol.

      Instead, they changed to 'embedded HDS flash streams', which I don't fully understand, but https://n1njahacks.wordpress.com/2015/01/29/how-to-save-hds-flash-streams-from-any-web-page/ is a useful link which features a php program that one can use to assemble of all the different f4f files.

      However, this requires to get a hold on the 'manifest', which in my case looks like http://adaptiv.wdr.de/z/medp/ww/fsk0/112/1120663/,1120663_12909203,1120663_12908906,1120663_12908907,.mp4.csmil/manifest.f4m?g=OREKBERCWCLP&hdcore=3.9.0&plugin=aasp-3.9.0.19.11

      All but one of its parts can be grabbed from the source codes of different web pages by means of WWW:Mechanize conveniently. The missing piece is the 'g=OREKBERCWCLP', which is newly generated upon each run of the video by clicking on the arrow. Therefore the only thought that I had to find the piece programatically was to run the embedded video (but how??) and then use something like ethereal of tcpdump.

      Any better ideas?

        Any better ideas?

        :) if get-flash-videos doesn't cater to website of your interest, submit a feature request,

        or program a solution yourself

        rtmpdump or flvstreamer is what get-flash-videos plugins use when they figure out the secret URL ... if they don't support HTTP Live Streaming find something that does or program a solution

        plugin writers also use tamarin abcdump, swfinvestigator/firebug+livehttpheaders, to figure out what how/what the magic urls are

        thats all the secrets right there :)
