* avcodec/wmadec: fix WMA gapless playbackbnnm2021-09-12
| | | | | | | | | | | | | Fixes trac issue #7473. Removes encoder delay (skip samples) and writes remaining frame samples after EOF to get correct sample count. Output is now accurate vs players that use Microsoft's codecs (Windows Media Format Runtime). Tested vs encode>decode WMAv2 with MS's codecs and most sample rate/bit rate/channel/mode combinations in ASF/XWMA. WMAv1 appears to use the same delay, from FFmpeg samples.

* avcodec/wmadec: Reduce the size of tables used to initialize VLCAndreas Rheinhardt2020-12-08
| | | | | | | | By switching from ff_init_vlc_sparse() to ff_init_vlc_from_lengths() one can replace a table of codes of type uint16_t by a table of symbols of type uint8_t, saving space. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
