* Implement time-based resume and playback start.Michael Sevakis2014-03-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | This complements offset-based resume and playback start funcionality. The implementation is global on both HWCODEC and SWCODEC. Basically, if either the specified elapsed or offset are non-zero, it indicates a mid-track resume. To resume by time only, set elapsed to nonzero and offset to zero. To resume by offset only, set offset to nonzero and elapsed to zero. Which one the codec uses and which has priority is up to the codec; however, using an elapsed time covers more cases: * Codecs not able to use an offset such as VGM or other atomic formats * Starting playback at a nonzero elapsed time from a source that contains no offset, such as a cuesheet The change re-versions pretty much everything from tagcache to nvram.

* VGM Codec: Improve time and fade behavior. Tweak minor misc.Michael Sevakis2013-03-06
| | | | | | | | | | | | | | | | | Prevents cutoff of tracks, especially short ones: * Extend looped tracks by fade length to fade at start of loop repeat. * No fade occurs for non-repeating track only having an intro. * Uses id3.tail_trim field to store fade duration. Use libGME built-in elapsed time reporting instead of custom calculation: * libGME already reports in milliseconds. * Don't advance time counter when Repeat == One. It just runs the progress over the length limit. Fix a comment about sample rate and set the reported bitrate to be accurate for 44.1 kHz stereo. Change-Id: I3ede22bda0f9a941a3fef751f4d678eb0027344c
