* cabac: Make CABAC states hardcodedAnton Khirnov2015-10-08
| | | | | | | There is not much reason to generate such a small table at runtime. Signed-off-by: Derek Buitenhuis <derekb@vimeo.com> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* w32pthreads: Load dynamically loaded functions on demandHendrik Leppkes2015-10-07
| | | | | | | This removes the requirement of calling w32thread_init before being able to use the threading primitives. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* w32pthreads: Add pthread_once emulationHendrik Leppkes2015-10-07
| | | | | | | | The emulation uses native InitOnce* APIs on Windows Vista+, and a lock-free/allocation-free approach using atomics and spinning for Windows XP. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* avconv: Do not try to configure filter outputs without streamsLuca Barbato2015-10-07
| | | | | | Prevent a NULL-dereference. CC: libav-stable@libav.org
* configure: When disabling a library disable all the related componentsLuca Barbato2015-10-07
| | | | | | This way is sufficient to use the component specific configure variable and not guard against the global library configure variable in code that is outside it (e.g. checkasm).
* dcadec: reorganise context dataAlexandra Khirnova2015-10-07
| | | | | | | | | place primary audio coding header data into DCAAudioHeader structure to make DCAContext clearer and move channel related data to DCAChan structure to make them easier to use by extensions Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* g2m: Relax resolution change constraintsVittorio Giovara2015-10-07
| | | | | | | Do not fail when original resolution is smaller than current one, as the frame buffer is resized automatically. Signed-off-by: Vittorio Giovara <vittorio.giovara at gmail.com>
* mmaldec: be more tolerant against MMAL not returning decoded outputwm42015-10-04
| | | | | | | | | | | | | | | | | | | | | | | | | 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>
* mmaldec: refactor to have more context per MMAL input bufferwm42015-10-04
| | | | | | | | | | | | | | 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.

* rangecoder: Use AV_RB16 instead of bytestream_get_be16Vittorio Giovara2015-10-04
| | | | | | | | Silence an incompatible-pointer-types-discards-qualifiers warning from clang. rangecoder.c:58:34: warning: passing 'uint8_t **' (aka 'unsigned char **') to parameter of type 'const uint8_t **' (aka 'const unsigned char **') discards qualifiers in nested pointer types [-Wincompatible-pointer-types-discards-qualifiers]
* hevc: Simplify logical checkVittorio Giovara2015-10-04
| | | | | | The intended meaning is "if this block is the first block in a slice then its left boundary is a slice boundary". Silence a logical-not-parentheses warning from gcc.

| | | | | | Silence a warning due to frame assignment in dvenc. All uses of the reference in dvdec are read only, except the ones in the main decoding function, so use the frame pointer directly there.

* matroskaenc: Don't write a track language tagJohn Stebbins2015-10-03
| | | | | | | | | "language" is not an offical matroska tag. Track languages are specified with the MATROSKA_ID_TRACKLANGUAGE ebml. Writing the tag overrides the ebml specified language during playback with libav and some other players. Signed-off-by: Anton Khirnov <anton@khirnov.net>

* dnxhddata: Deduplicate cid 1256 chroma tableChristophe Gisquet2015-10-02
| | | | | | | | | | CID 1256 is specified as using the same table for luma and chroma, which is the same as CID 1235 luma table. This is consistent with the format supposedly being RGB, although most sequences seem to actually be YCbCr-encoded.

* dnxhddata: Deduplicate dnx100 tablesJeremy James2015-10-02
| | | | | | | Tables 1258 and 1259 were not zigzagged when added, so it was not possible to notice the equivalence. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>

* dnxhddata: Fix 10-bit DNxHD quant matricesJoseph Artsimovich2015-10-02
| | | | | | | | | | | | Convert them to zigzag order, as the rest of them are. When I was adding support for 10-bit DNxHD, I just copy-pasted the missing quant matrices from the spec. Now it turns out the existing matrices in dnxhddata.c were in zigzag order. This resulted in wrong quantization for 10-bit DNxHD. The attached patch fixes the problem by converting 10-bit quant matrices to zigzag order. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
* x264: Add option to force IDR framesDerek Buitenhuis2015-10-01
| | | | | | | When forwarding the frame type information, by default x264 can decide which kind of keyframe output, add an option to force it to output IDR frames in to support use-cases such as preparing the content for segmented streams formats.
* x264: Expose the NV21 input supportYu Xiaolei2015-10-01
| | | | | | | | | x264 build 147 adds the native support for NV21. Useful to avoid additional pixel format conversion when encoding from a wide range of capture devices, Android among those. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>

| | | | | | | | | | | These field are difficult to interpret, and are provided by a single encoder (mpegvideoenc). In general they do not belong to a structure containing raw data only, so remove them from AVFrame. Mpegvideoenc now uses a private field in Picture for its internal computations.

* dnxhddec: Decode and use interlace mb flagChristophe Gisquet2015-09-29
| | | | | | | | | | | | | | | | | | | | This bit is 1 in some samples, and seems to coincide with interlaced mbs and CID1260. 2008 specs do not know about it, and maintain qscale is 11 bits. This looks oversized, but may help larger bitdepths. Currently, it leads to an obviously incorrect qscale value, meaning its syntax is shifted by 1. However, reading 11 bits also leads to obviously incorrect decoding: qscale seems to be 10 bits. However, as most profiles still have 11bits qscale, the feature is restricted to the CID1260 profile (this flag is dependent on a higher-level flag located in the header). The encoder writes 12 bits of syntax, last and first bits always 0, which is now somewhat inconsistent with the decoder, but ends up with the same effect (progressive + reserved bit).

| | | | | | | | | Note that convergence_duration had another meaning, one which was in practice never used. The only real use for it was a 64 bit replacement for the duration field.

* libopenh264enc: Use av_log() to log messagesGregory J. Wolfe2015-09-29
| | | | | | | | | | | | | | File libopenh264enc.c has been modified so that the encoder uses av_log() to log messages (error, warning, info, etc.) instead of logging them directly to stderr. At the time the encoder is created, the current libav log level is mapped to an equivalent libopenh264 log level. This log level, and a message logging function that invokes av_log() to actually log messages, are then set on the encoder. This contains further changes and simplifications by Michael Niedermayer and Martin Storsjö. Signed-off-by: Martin Storsjö <martin@martin.st>
