These are test content for https://codereview.chromium.org/11778086/ and
https://codereview.chromium.org/11830024/.

I'd like all the reviewers to review the naming, especially for the mp4 files.
While I don't want to bike shed, I'd like feedback on indicating that these are
fragmented and CENC (vs. other ISO protection schemes). We also have existing
files named "_dash", and I'm not sure how those fit in.

Could you also update the README file in this folder about naming scheme?

Some random toughts:

Why we use "-" for webm but "." for mp4? Does it make sense to consolidate the
naming format?

I guess it's a little hard for readers to understand what "un" and "enc" are
for. "enc" can easily be read as "encode". Can we use "unencrypt" and "encrypt"
explicitly? Or if the name is too long, can we use some code, like "e" for
enctypted and "c" for clear and document them in the README?

[ddorwin, 2013-01-10 17:57:31]

I standardized the names, changed "un" to "clear", and updated the README. Since
the files are too large to upload, you can't get a diff of the README, but you
can Download the patch.

PTAL.

The names are more consistent now. The only question remaining for me is whether
we need "frag-".
acolwell, what should the _dash files really be named? Should they be "_frag"?

I will delete the files I renamed in a future CL so tests continue to pass.

LGTM. I think we should replace _dash w/ _frag so all the files are consistently
named. The dash is only there because that is what MP4Box appended to the source
file names when I created the file.

_dash and _frag seem to be synonyms, unifying makes sense to me.

WDYT about adding -av to bear-1280x720, bear-1280x720_dash, and bear-640x360?

[ddorwin, 2013-01-10 22:39:21]

I replaced _dash with _frag.

I added "-av" to those files. I left the non-special files alone, since there
are many others and it's somewhat assumed in a basic bear* file.
