[vlc-devel] [PATCH 00/21] input/input: add support for secondary resources in MRL

[Filip Roséen]

Introduction
-------------------------------------------------------------------------------

These set of patches are directly related to what was discussed during the
VideoLan meeting in Vienna earlier this year; in short it allows us to specify
that one would like to access a sub-item, inside a sub-item, inside a sub-item
(like playing an mkv inside a rar, inside a zip, over http).

 - The documentation available in the commits should provide detailed
   explanation of what is going, and why these changes are required.

 - I've included sample usage of the new functionality in the patch related to
   the changes made to access/cdda.

tl;dr: allow us to store "secondary resource information" directly in the MRL,
so that one can save and restore a playlist without losing this information, and
request a single entity within an entity to be processed in a uniform manner.

Request
-------------------------------------------------------------------------------

There is one thing I am not at all satisfied with, and it is the name of
"vlc_stream_CreateFragmentedMRL". I hope the documentation associated with the
function is enough to spawn a few ideas for a better name.

If you got one, please let me know and we can change it in the future!

Note
-------------------------------------------------------------------------------

In order to not completely overload vlc-devel with patches, I have decided to
only push the patches that are relevant for the new functionality (plus a
sample usage in access/cdda).

Locally I have patches that replaces the archive-accessors/stream-filters, if
you are interested see the relevant commits under the following link.

Given that there are twenty-one commits in this patch-batch I feel like a double
ascii-art combo is required; as such, here's a cow and a dog.
