Implement seek and frame caching. A nice starting point is explained in issue #32
Some ideas:

  • Make the MediaBlockBuffer size either dynamic or configurable
  • Some indexing might work but I am not sure...
  • On seek command set a Direction property and perform a seek in the background. Upon play make the direction forward. If we are backwards rendering frame then seek in the background so it seems smoother than what it currently looks like.

Related issue #32 and a good starting point:
https://github.com/lbrandy/ffmpeg-fas

This does indexing which can be related to caching policy

* starting with seek indexing. Related to issue #139

* continued work on seek indexing.

* Generalizing sorted binary search algorithm. Continued work on seek indices. See issues #250 and #139

* improved and simplified seek logic.

* minor renaming and added seek error checking.

* logging when using a video seek index entry.

* fixing frame start offset by offseting them by main component.

Better rendering and Timing (#329)
ffe20d3 
* experimenting with better clocks and rendering

* clock relative timing

* more advancements in relative timing. Clocks are still very messy at this point.

* continued work on timing

* simplifying relative clock methods

* room for blocks logic -- still needs work.

* experimentation of making room for blocks.

* still working on timing and more natural rendering and decoding

* more fine-grained control over clock

* It's a house of cards... but it's beautiful!

* removing some unused code and adding some notes.

* a new approach to sync-buffering

* splitting block rendering logic into individual functions to ensure more clarity

* starting with new sync-buffering logic.

* relative time track timing

* automatic time sync detection

* more refinements to blockrenderingworker

* additional minor improvements to blockrendering

* faster stream start without syncbuffering on main

* samll adjustemnts and simplifications.

* More documentation. Migrating log outputter to worker base

* re-enabling AV sync

Resolving issues #315, #310, #303, #299, #284 and #139
