[FFmpeg-devel] [PATCH] Allow HLS to decrypt stream when using a data url for the key

[Simon Black]

Please bear with me, I will create some test URLs from within our service (that has no licensing issues).

If HLS is trying to play an encrypted stream where the key is a data URL rather
than a file based key HLS will not work.

a data url within the key is one such as:
#EXT-X-KEY:METHOD=AES-128,URI="data:;base64,dKbarMNMRSmPPEXQ3dDCNA=="

The error message is reported as:

[https @ 0x7f9eb00120c0] HTTP error 404 Not Found
Unable to open key file

https://BASE.URL.HERE/data:;base64,dKbarMNMRSmPPEXQ3dDCNA
==

This is caused as the URL is created with the value in URI field of the
EXT-X-KEY tag using

ff_make_absolute_url(seg->key, sizeof(seg->key), url, key);

the data: schema is ignored.

do you have a public url with which to test/verify this bugfix ?

Many things microsoft did are stupid, but not doing something just because
microsoft did it is even more stupid. If everything ms did were stupid they
would be bankrupt already.
