Stephen Hutchinson	0dd201d947	libx265: Remove experimental flag when encoding 4:2:2 and 4:4:4 4:2:2 and 4:4:4 support in the HEVC standard was approved in October 2014 as part of HEVC Version 2 and published in January 2015: http://www.itu.int/ITU-T/recommendations/rec.aspx?rec=12296 http://www.itu.int/rec/T-REC-H.265-201410-S https://hevc.hhi.fraunhofer.de/rext Reviewed-by: Derek Buitenhuis <derek.buitenhuis@gmail.com> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago

Timothy Gu	9ba54c1b82	avcodec: Remove libaacplus TODO: bump minor It's inferior in quality to fdk-aac and has an arguably more problematic license. As early as 2012, a HydrogenAudio user reported: > It has however one huge advantage: much better quality at low bitrates than > faac and libaacplus. (https://hydrogenaud.io/index.php?PHPSESSID=ckiq394pdglka0kj2fin6ij8t7&topic=95989.msg804633#msg804633) I myself have made a few spectrograms for a comparison of the two encoders as well. The FDK output is consistently better than the libaacplus one, in all bitrates I tested. libaacplus license is 3GPP + LGPLv2. 3GPP copyright notice is completely proprietory, as follows: > No part may be reproduced except as authorized by written permission. > > The copyright and the foregoing restriction extend to reproduction in > all media. > > © 2008, 3GPP Organizational Partners (ARIB, ATIS, CCSA, ETSI, TTA, TTC). > > All rights reserved. (The latest 26410-d00 zip from 3GPP has the same notice, but the copyright year is changed to 2015) The copyright part of the FDK AAC license (section 2) is a copyleft license that permits redistribution under certain conditions (and therefore the LGPL + libfdk-aac combination is not prohibited by configure): > Redistribution and use in source and binary forms, with or without > modification, are permitted without payment of copyright license fees > provided that you satisfy the following conditions: > > You must retain the complete text of this software license in > redistributions of the FDK AAC Codec or your modifications thereto in > source code form. > > You must retain the complete text of this software license in the > documentation and/or other materials provided with redistributions of > the FDK AAC Codec or your modifications thereto in binary form. > > You must make available free of charge copies of the complete source > code of the FDK AAC Codec and your modifications thereto to recipients > of copies in binary form. > > The name of Fraunhofer may not be used to endorse or promote products > derived from this library without prior written permission. > > You may not charge copyright license fees for anyone to use, copy or > distribute the FDK AAC Codec software or your modifications thereto. > > Your modified versions of the FDK AAC Codec must carry prominent > notices stating that you changed the software and the date of any > change.

Mats Peterson	b34c9d1b9d	lavc/rawdec: Use AV_PIX_FMT_PAL8 for raw 1 bpp video in AVI From https://msdn.microsoft.com/en-us/library/windows/desktop/dd318229%28v=vs.85%29.aspx: "If biCompression equals BI_RGB and the bitmap uses 8 bpp or less, the bitmap has a color table immediatelly following the BITMAPINFOHEADER structure. The color table consists of an array of RGBQUAD values. The size of the array is given by the biClrUsed member. If biClrUsed is zero, the array contains the maximum number of colors for the given bitdepth; that is, 2^biBitCount colors." Nothing about "monochrome" here. Unfortunately, pal8 to monow conversion seems a bit flaky, but that's another story. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago

wm4	14a90c9ef0	mmaldec: limit internal buffering This uses a new MMAL feature, which limits the number of extra frames that can be buffered within the decoder. VIDEO_MAX_NUM_CALLBACKS can be defined as positive or negative number. Positive numbers are absolute, and can lead to deadlocks if the user underestimates the number of required buffers. Negative numbers specify the number of extra buffers, e.g. -1 means no extra buffer, (-1-N) means N extra buffers. Set a gratuitous default of -11 (N=10). This is much lower than the firmware default, which appears to be 96. This is backwards compatible, but needs a symbol only present in newer firmware headers. (It's an enum item, so it requires a check in configure.)	9 years ago
