Description

WRITE DESCRIPTION HERE Czech TV has its web. Some videos on the web are playable only in a time of broadcasting of the same program. It was possible to download these videos without problem during the broadcasting. The Czech TV changed its web and now I am not able to download it. Please, could you look at it and modify the program? Regards Jim

The released extractor version has known issues. I tried PR #30713, but it failed to extract.

The site reported "Pořad je možné přehrát pouze souběžně s televizním vysíláním" which I would add to the error text search in the PR as "program can only be played simultaneously with TV broadcast".

If you can find a way of playing the show in your browser, please pass on the URL used for that.

I am sorry but I don't know what I shall do for the issue. Does your comment mean that you are prepareing a new version? The url is https://www.ceskatelevize.cz/porady/14890395001-spolecne-koreny-koncert-s-ukrajinou/ but the broadcast ended and the video isn't playable.

yt-dl can't be expected to pull a video that the site doesn't offer.

I'm no kind of expert on this site, beyond developing PR #30713. When that gets merged, the master branch and the next release will be able to fetch a lot more shows, including live broadcasts. I was able to watch a show live in the UK using this code (sadly, my missing Czech skills limited this to watching).

What we do is find the idec code for the show plus a parameter iframe_hash, and then fetch the embedded player page https://www.ceskatelevize.cz/ivysilani/embed/iFramePlayer.php?hash=iframe_hash&origin=iVysilani&autoStart=true&IDEC=idec. This page should contain all the required metadata including the media links, if available. But in this case the playlist that we need is absent, and the message that I quoted above is found.

Perhaps they'll put up a new page with a final version for replaying once it's been edited, etc.

I found a same cases with a different videos. Urls of the videos:

I won't be able to monitor the 27 March show but let's have a look at the 31 March one, Woman Walks Ahead.

I wonder if it's a policy to make certain foreign movies available only at the time of broadcast for rights reasons. Also, I wonder how simultaneous "souběžně" means.

[hawkinsjim]

I wrote you some urls. I'd like to ask you, if you have enough infromation for the modification which I asked. I can find and write here next urls if needed.

I am also interested in this issue. Some archival records are time-limited for licensing reasons, and I have also encountered limitations of availability on the Czech Republic's teriotorium. However, this should not be a problem for e.g. this interview with Sir Terry Pratchett - https://www.ceskatelevize.cz/porady/1093836883-na-plovarne/211522160100014/, but better check.
