I get this error running youtube-dl with the -v option:

Description of your issue, suggested solution and other information

All errors occur on pip console, after installing youtube-dl with pip install youtube-dl. I tested on both QPython with Python 2.7 and Python 3.2. More often the error HTMLParseError occurs.

[dstftw]

1. platform.platform() is broken on your python implementation report it to its developers.
2. Post the output with --dump-pages.

[vmassuchetto]

1. Looks like it has already been reported -- not much attention, though;
2. Link to --dump-pages output: https://www.pastiebin.com/59230cba33cc0

Please follow #13822 for the second issue. For the first issue, I suggest moving away from QPython, which is quite old and not working well with Android. Python 3.6+ is recommended.
