* dnxhdenc: mark CID 1260 encoder experimentalChristophe Gisquet2015-10-08
| | | | | | | | | | | The MBAFF handling recently introduced on the decoder side shows that the encoder does not support it correctly. Therefore, make the related profile experimental. Furthermore, current encoder logic treats it as unable to encode as progressive, which isn't the case. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
* dnxhddata: introduce and use MBAFF flagChristophe Gisquet2015-10-07
| | | | | | | MBAFF-like handling of interlaced content in CID 1260 is different from the other CIDs, and in particular doesn't use the same syntax. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

* dnxhddec: better support for 4:4:4Christophe Gisquet2015-10-07
| | | | | | | | | | | | | | | | Profiles 1256 & 1270 (currently) signal at the frame header and MB levels the colorspace used, either RGB or YUV. While a MB-level varying colorspace is not supported, whether it is constant can be tracked so as to determine the exact colorspace. This requires having bitdepth and the ACT and 4:4:4 flags, in turn needing the CID. Because setting those before having validated enough things may result in invalid/unset DSP fucntions, setting the bitdepth in the context is delayed. It is not tested against a true RGB sequence, though. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

* doc/encoders: Fix libkvazaar documentationArttu Ylä-Outinen2015-10-07
| | | | | | | | | The -threads option is ignored with libkvazaar since it does not have any of the AV_CODEC_CAP_{FRAME,SLICE,AUTO}_THREADS capabilities. This commit removes the incorrect documentation as well as the no-op of setting the number of threads in libkvazaar encoder. Signed-off-by: Arttu Ylä-Outinen <arttu.yla-outinen@tut.fi>

* vp9: don't keep a stack pointer if we don't need it.Ronald S. Bultje2015-10-07
| | | | | | | | This saves one register in a few cases on 32bit builds with unaligned stack (e.g. MSVC), making the code slightly easier to maintain. (Can someone please test this on 32bit+msvc and confirm make fate-vp9 and tests/checkasm/checkasm still work after this patch?)
* avcodec/libx264: silence -WaddressGanesh Ajjanagadde2015-10-07
| | | | | | | | | | This patch moves the pointer validity check outside the macro, and silences the -Waddress observed with GCC 5.2. Note that this changes the error message slightly, from: "bad option..." to "Error parsing option...". Signed-off-by: Ganesh Ajjanagadde <gajjanagadde@gmail.com>

* avformat/httpauth: Add space after commas in HTTP/RTSP auth headerAndrey Utkin2015-10-07
| | | | | | | | | | | | This fixes access to Grandstream cameras, which return 401 to ffmpeg otherwise. VLC sends Authorization: header with spaces between parameters, and it is known to work with Grandstream devices and broad range of other HTTP and RTSP servers, so author considers switching to such behaviour safe. Just for record - RFC 2617 (HTTP Auth) does not specify the need in spaces, so this is not a bug of FFmpeg. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
