kHLSPropProbably ?
    ^^^^

Except that HLS only makes sense with proprietary codecs, and they are always
supported on Android.
I think you can probably remove this #ifdef and just use this definition.

[amogh.bihani, 2014/03/24 11:04:59]

Done.

+#else
+const char* kHLSProbably = "maybe";

[ddorwin, 2014/03/21 21:52:16]

Which would make this kHLSProbably - it's only used for HLS with non-proprietary
types.

Since this is broken, maybe we should name it kHlsShouldBeNot with a TODO to
remove it.

[amogh.bihani, 2014/03/24 11:04:59]

Done.
Now since there is no #ifdef, it is not needed :)

All these tests require is adding "audio/x-wav" to format_codec_mappings.

Yes, I will do it in the other CL.

You probably mean for this comment to come after 114.

[amogh.bihani, 2014/03/24 11:04:59]

According to whatwg[1], line 113 is a correct result. I had made these testcases
taking into consideration what is given on this page.

[ddorwin, 2014/03/21 21:52:16]

General: Add tests where there are two audio codecs or two video codecs - both
where one is valid and where both are valid.
It may not be that important in real life, but we should at least know what
we're returning.

[amogh.bihani, 2014/03/24 11:04:59]

Done. I also did the same for audio mime_types.

+IN_PROC_BROWSER_TEST_F(MediaCanPlayTypeTest, CodecSupportTest_webm) {

[ddorwin, 2014/03/21 21:52:16]

General #2: We should also have a few codec case-sensitivity tests. (Codecs are
case-sensitive.) There's no need to test case-insensitivity of the container -
that should be in the layout tests.

[amogh.bihani, 2014/03/24 11:04:59]

Done. In that case many layout tests need to change [1].
