Description

Radio Televisión Española (RTVE, Spanish for Spanish Radio & Television Company) is changing the name of his site "A la carta" (On demand) to "RTVE Play", also modifying their URLs for accessing contents. The URL changed slightly, modifying the folder alacarta for play, making the current extractor version unable to continue processing the page and falling back to the generic extractor (which also fail).

Old URLs had the following structure (for example, the last emission of "Saber y Ganar" as of today, July 11 2021): https://www.rtve.es/alacarta/videos/saber-y-ganar/edicion-fin-semana-11-07-21/5977613/ While new URLs have the following structure: https://www.rtve.es/play/videos/saber-y-ganar/edicion-fin-semana-11-07-21/5977613/

Manually modifying the URL before running the command (i.e. changing play for alacarta) results in a successful execution:

... (Log was cut)

Ideas for fix:

• Drop support for alacarta in favour of play
• Add the support for play, redirecting the download process to alacarta

[dirkf]

Just changing the URL pattern appears to fix this, as expected from the problem description: eg, change the fragment (alacarta/videos|filmoteca) in the definition of _VALID_URL to ((alacarta|play)/videos|filmoteca) in extractor/rtve.py.

This is actually a third option, supporting play and alacarta together. The name of the extractor could be changed to reflect the new service name; then:
