Steinar H. Gunderson	2a293ec7ac	avcodec: add Newtek SpeedHQ decoder This decoder can decode all existing SpeedHQ formats (SHQ0–5, 7, and 9), including correct decoding of the alpha channel. 1080p is decoded in 142 fps on one core of my i7-4600U (2.1 GHz Haswell), about evenly split between bitstream reader and IDCT. There is currently no attempt at slice or frame threading, even though the format trivially supports both. NewTek very helpfully provided a full set of SHQ samples, as well as source code for an SHQ2 encoder (not included) and assistance with understanding some details of the format.	8 years ago

Alexandra Hájková	ffa190d047	Move VLC and RL_VLC_ELEM structure definitions to a separate header Use the newly created vlc.h directly instead of including get_bits when needed. The VLC and RL_VLC_ELEM structures are independent from the bitreader. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	9 years ago
