We shouldn't abort() on the source buffer for every seek. The buffered region is no longer guaranteed to be contiguous, so take that into account when determining if the segment to be loaded needs to be updated. Allow media sources to handle duration updates internally, don't set the duration on every segment download. Doing so was actually causing the range removal algorithm to run when the final segment came in slightly below the duration advertised in the m3u8.
Use native MediaSources for browsers that support them (currently Chrome) and fall back to Flash for everyone else. Seeking doesn't work as well in Flash as it did previously because the improved duration calculations have not been migrated yet but otherwise things seem to work.
When a NAL unit had trailing zeroes that were split across pushes to the H264Stream, the parser would go into an infinite loop. Instead, make sure we never advance the parser beyond the current push and advance the sync point to a valid position before starting processing. Add HTML-HLS dependencies to the example page.
Bump up to a vjs 5 release candidate. Make the necessary changes to work with the updated APIs. Convert the project from a subclass of the Flash tech to a source handler.
Keep the example page simple. Add a live graph of cue point PTS position versus media timeline position. Update the display so it works with live content.
Closes#272.

Adaptation Field vars. Use Random Access Indicator
The Random Access Indicator tells us whether something is a keyframe.
Set the stream's frame's keyFrame property to true if the Random Access

The minified 4.x build mangles "preload" passed in as options, which prevents it being overridden in data-setup or through the video element attribute. Switch to the dev version so that preload settings can be adjusted.

Used an adaptive, encrypted m3u8 on the example page and included hex dump utilities. Fixed formatting issues with the hex dump utility. Passed a 16-byte IV to the decrypter in drainBuffer(). Swapped byte order for the keys so they are not misintrepreted as little-endian. Added fields to the muxer test page to mux encrypted segments. Updated tests. Fixed docs on using openssl to test encryption and decryption.
Remove async tag queueing from HLS since that is now happening in the media sources plugin itself. Update the location of MSE source files. Bump the dependency in package.json. Two tests are still failing with this commit but will be fixed shortly.
Pushing an entire segment worth of FLV tags into the source buffer at once caused noticeable delays with high-bitrate segments. Instead, wrap each call to appendBuffer in a setTimeout of zero so that the browser has a chance to render frames while the segment is being transferred to the SWF. Make sure that appends-in-progress are cleared if a seek is initiated.
Get rid of leftovers from the previous iteration of managing manifest and stream downloading. That logic has been consolidated into the main plugin file.
Instead of only supporting the src attribute, check options.sources for HLS on init. This means re-implementing something that looks a lot like video.js's source selection algorithm. That's another reason to consider converting this plugin into a tech but I'm deferring that for now.
Bipbop is great for testing because it displays so much information about the current state of the video. Use a standard "src" attribute to initialize the plugin in the example.
Move more of the manifest management and segment loading into a more customary location for a plugin implementation. Get a single segment downloading and playing. Add test cases for the plugin initialization and first segment download. Use a linked version of media sources to pick up an event listening implementation on SourceBuffer that doesn't require an unminified version of video.js.
Switch the example to use the locally committed HLS fixture to avoid CORS issues when trying it out. It will still be necessary to load the example page through a web server, though.
The example page is very ugly but attempts to play two segments of bip-bop. The first segment plays fine but the player seems to jump to the end of the second segment after the first one finishes. Add bip bop test fixtures.
loadWord wasn't incrementing the position in the byte stream so fix it so that the accounting is taken care of. Replace a bunch of single-letter variable names with more descriptive terms. Add some comments. Add tests for exponential golomb parsing.
Fix up a couple remaining issues with the HLS->FLV translation. At this point, we've validated that the generated file can be played back in VLC if you download it to your computer. Added another ts segment for testing purposes. Added unit testing that traverses the generated FLV and validates the tags are constructed correctly and seem consistent.
The parser can process the example TS but it doesn't appear to be correctly formed. The player does seem to correctly interpret the video duration, but the display area is black and there is no audio.
