==Possible Video/Fullscreen Bugs==
 
===Small and easy bugs===
 
* [https://bugzilla.mozilla.org/show_bug.cgi?id=715323 Bug 715323] nsBuiltinDecoderReader::NotifyDataArrived() should have a 64bit offset parameter. Easy first bug to get acquainted with our process.
 
* [https://bugzilla.mozilla.org/show_bug.cgi?id=620159 Bug 620159] nsVorbisState::Time needs to handle failure from return from MulOverflow. (This may conflict with [https://bugzilla.mozilla.org/show_bug.cgi?id=601535 Bug 601535])
 
* [https://bugzilla.mozilla.org/show_bug.cgi?id=620164 Bug 620164] nsTheoraState::MaxKeyframeOffset doesn't need to use MulOverflow
(This may conflict with [https://bugzilla.mozilla.org/show_bug.cgi?id=601535 Bug 601535])
 
* [https://bugzilla.mozilla.org/show_bug.cgi?id=711839 Bug 711839] ---disable-ogg configure option breaks build after [https://bugzilla.mozilla.org/show_bug.cgi?id=689834 bug 689834]
 
* [https://bugzilla.mozilla.org/show_bug.cgi?id=702161 Bug 702161] videocontrols.xml has anonymous function event listeners that are added but never removed
 
[https://bugzilla.mozilla.org/show_bug.cgi?id=704326 Bug 704326] Standalone audio files should have an intrinsic size so they don't look awkward
 
[https://bugzilla.mozilla.org/show_bug.cgi?id=713383 Bug 713383] Directly viewed images should be printed with a transparent background on the body
 
[https://bugzilla.mozilla.org/show_bug.cgi?id=681548 Bug 681548] Visual refresh of controls (needs graphics from Stephen Horlander first)
 
===Easy but not as small===
 
* [https://bugzilla.mozilla.org/show_bug.cgi?id=601535 Bug 601535] content/media should use CheckedInt.h
Rework content/media/ to use CheckedInt to guard against integer overflow instead of the custom int overflow checking code defined in VideoUtils.h (I already suggested this to Steven Tseng, so you might want to check that he hasn't accepted this before suggesting other students tried working on it).
 
* [https://bugzilla.mozilla.org/show_bug.cgi?id=705234 Bug 705234] Inconsistent use of "full screen" and "full-screen" across browser and DOM strings, should use "fullscreen" instead Sometimes in strings we use "full-screen", "full-screen mode" and "fullscreen". We should use "fullscreen" instead. This is mostly string changes, but we actually need to rename the strings as well, otherwise localizers won't notice that a change occurred (they may or may not need to).
 
===Not quite as easy===
 
* [https://bugzilla.mozilla.org/show_bug.cgi?id=689374 Bug 689374] Add specialized audio controls for small-dimension media
 
* [https://bugzilla.mozilla.org/show_bug.cgi?id=715141 Bug 715141] Using keyboard to switch zoom level when viewing images directly
 
* [https://bugzilla.mozilla.org/show_bug.cgi?id=708814 Bug 708814] Should fade out videocontrols even if there's no mouse movement
Video controls, all in Javascript, I'm keen to see this one done.
 
* [https://bugzilla.mozilla.org/show_bug.cgi?id=516811 Bug 516811] "load" events for poster image loads bubble out
(Fix should be similar to that for bug 715469, but may involve some C++ level DOM manipulation)
 
* [https://bugzilla.mozilla.org/show_bug.cgi?id=680321 Bug 680321] Media preload state should reset in resource selection algorithm
Changes need to be made to nsHTMLMediaElement.cpp, so should be "easy" to get your head wrapped around it...
 
* [https://bugzilla.mozilla.org/show_bug.cgi?id=517363 Bug 517363] Preserve video poster aspect ratio when scaling
Would be good to see this fixed!
 
* [https://bugzilla.mozilla.org/show_bug.cgi?id=711742 Bug 711742] HTML5 video's "Save Video As" saves an empty .webm file if you have not actually played the video. The patch that causes this to regress has been identified, so that should give clues of how to fix it.
 
* [https://bugzilla.mozilla.org/show_bug.cgi?id=601032 Bug 601032] test_play_twice fails with sound disabled
 
* [https://bugzilla.mozilla.org/show_bug.cgi?id=618737 Bug 618737] The <video> element develops a tabindex attribute out of nowhere
(I'm not the best mentor for this one, Boris Zbarsky probably is, but it sounds simple enough to fix...)
 
* [https://bugzilla.mozilla.org/show_bug.cgi?id=712836 Bug 712836] Reloading live stream causes HTMLMediaElement.error.code to be copied to new clone of resource
 
* [https://bugzilla.mozilla.org/show_bug.cgi?id=708553 Bug 708553] Hovered element state is not relinquished when entering and exiting fullscreen mode. Requires digging into how Firefox manages event state for :hover.
 
* [https://bugzilla.mozilla.org/show_bug.cgi?id=500784 Bug 500784] Video/audio files over 2^31 bytes in length are unseekable
We'd need changes made to the nsMediaCache to support 64bit file sizes, along with changes to the nsBuiltinDecoderReader-subclass seek implementations. We care more about seeking in large WebM files rather than in Ogg files, i.e. don't go to the trouble of changing the Ogg seeking code, that'll be painful! We can file a follow up for that work.
 
* [https://bugzilla.mozilla.org/show_bug.cgi?id=714071 Bug 714071] The Show Statistics setting is not preserved when toggling the full screen mode. Fullscreen and <video> in one bug! Your students will love this one! I have no idea why this is happening, maybe they won't love it.
 
* [https://bugzilla.mozilla.org/show_bug.cgi?id=677122 Bug 677122] Changing media fragment portion of URL in video documents doesn't update start/end times
