2015-10-08dnxhdenc: mark CID 1260 encoder experimentalChristophe Gisquet
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>
2015-10-07dnxhddata: introduce and use MBAFF flagChristophe Gisquet
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>
2015-10-07dnxhddec: better support for 4:4:4Christophe Gisquet
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>

2015-10-07doc/encoders: Fix libkvazaar documentationArttu Ylä-Outinen
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>

2015-10-07vp9: don't keep a stack pointer if we don't need it.Ronald S. Bultje
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?)
2015-10-07avcodec/libx264: silence -WaddressGanesh Ajjanagadde
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>

2015-10-05dnxhd: add better support for CIDs 1270 to 1274Jeremy James
These are DNxHR profiles with the following properties: - Variable size in a profile (property added in a previous commit), requiring variable-sized macroblock table; - Variable bitdepth, up to 12 bits. - Better validation of buffer sizes and positions Signed-off-by: Christophe Gisquet <christophe.gisquet@gmail.com> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
2015-10-05dnxhd: add CID 1270Christophe Gisquet
This a 4:4:4 10 bits profile, where image size is not fixed by the profile, and which strays a bit outside the old frame header parsing code. Fixes ticket #4581 (DNxHR is not stricly supported, but that sequence is). Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

2015-10-05dnxhddec: Introduce DNXHD_VARIABLEChristophe Gisquet
Currently not used, but will be used to indicate that a CIDEntry field is not set, because it is variable, and that checks should be adapted. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

2015-10-04mmaldec: be more tolerant against MMAL not returning decoded outputwm4
In some situations, MMAL won't return a decoded frame for certain input frames. This can happen if a frame fails to decode, or if a packet does not actually contain a complete frame. In these situations, we would deadlock (or actually timeout) waiting for an expected output frame, which is not ideal. On the other hand, there are situations where we definitely have to block to avoid deadlocks. (This mess is a consequence of trying to map MMAL's asynchronous and flexible dataflow to libavcodec, which is more static and rigid.) Solve this by doing a blocking wait only if the amount of buffered data is too big. The whole purpose of the blocking wait is to avoid excessive buffering of input data, so we can skip it if it appears to be low. The consequence is that libavcodec can gracefully return no frame to the API user. We want to track the number of full packets to make our heuristic work. But MMAL buffers are fixed-size, requiring splitting large packets. This is why the previous commit is needed. We use the ..._FRAME_END flag to remember packet boundaries, but MMAL does not preserve these buffer flags when returning buffers to the user. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
2015-10-04mmaldec: refactor to have more context per MMAL input bufferwm4
The next commit needs 1 bit of additional information per MMAL buffer sent to the MMAL input port. This information will be needed when the buffer is recycled (i.e. returned by the input port's callback). Normally, we could use MMAL_BUFFER_HEADER_FLAG_USER0, but that is unexpectedly not preserved. Do this by storing a pointer to FFBufferEntry in the MMAL buffer's user data, instead of an AVBufferRef. This also changes the lifetime of FFBufferEntry.
