Extract YouTube MPD Information

A Python script to extract youtubes MPD file and print the information to the console

Requirements

(Linux)
Python 2.7 or better
libxml2 (e.g., sudo apt-get install python-libxml2)
urllib2

Usage

Example Call (will download the MPD file to aspen.mpd)

python extract.py https://www.youtube.com/watch?v=GTGUa4J8XKw aspen.mpd

Output (of the above Example, URLs shortened/anonymized):

Output Information

MPDs usually contain multiple AdaptationSet XML tags. Those contain a MimeType of either:

audio/mp4
audio/webm
video/mp4
video/webm

Within one AdaptationSet there are multiple Representation tags, which then contain information for each representation:

Bitrate (in Kilobit per second)
Codec
Information for Video Only (in ExtraInformation column of generated output):

Video Width
Video Height
Video Frame Rate

extract-youtube-mpd's Issues

About work environment

I want to run this program on windows,but I met some problems.The libxml2 library exists in Anconda. Why does the runtime prompt not exist?

could you explain how to retrieve the MPD file

The project itself can't work on today's YouTube. Could you explain the theory how to retrieve the MPD file of a YouTube video so we can change the code?

Line mpdurl = html[html.find("dashmpd"):] returns empty

I am trying to execute the script using this command line
python3 extract.py https://www.youtube.com/watch?v=2d1VrCvdzbY test.mpd

But I don't seem to get a result or output.

Output:

File "extract.py", line 69, in
mpdurl = html[html.find("dashmpd"):]
TypeError: a bytes-like object is required, not 'str'

I have tried to fix this output with some .encode() next to the strings, and this solved at first the problem but it is still not returning an output.

It seems it is not able to find a result at line 69. Maybe the parameter is not called anymore "dashmpd"?
