* mpeg12: Add a common function to find the best frame rateMark Thompson2017-10-171-0/+4
| | | | | | | This will be used later in both the mpeg2_metadata filter and the VAAPI MPEG-2 encoder. Also adds a unit test. (cherry picked from commit b5859e0b04bdbe12c97cb12ac10a45d51d2d73c9)
* avcodec: add Newtek SpeedHQ decoderSteinar H. Gunderson2017-01-111-0/+9
| | | | | | | | | | | | | | 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.

| * Revert "mpeg12: move full_pel from MpegEncContext to Mpeg1Context"Janne Grunau2011-10-241-1/+0
| | | | | | | | | | | | | | | | This reverts commit da22ba7df461c13bf0b0eabc953303803a285d91 since it broke slice threading. Slice threading just duplicates MpegEncContext so every value used during mpeg_decode_slice has to be in it. A second patch will fix the illusion that Mpeg1Context is available in mpeg_decode_slice.
