* cmdutils: Add auto to threading capabilities reportVittorio Giovara2015-10-15
| | | | | | And use 'none' when such capabilities are not set. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>
* h264: Run VLC init under pthread_onceDerek Buitenhuis2015-10-14
| | | | | | | This makes the h.264 decoder threadsafe to initialize. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* thread: Provide no-op variants for pthread_onceLuca Barbato2015-10-14

* dxva: Include last the internal headerLuca Barbato2015-10-14
| | | | | It redefines _WIN32_WINNT, possibly causing problems with the w32pthreads.h header.
* httpauth: Add space after commas in HTTP/RTSP auth headerAndrey Utkin2015-10-14
| | | | | | | | | | | This fixes access to Grandstream cameras, which return 401 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. See RFC 2617 (HTTP Auth). Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* rtmpproto: Write correct flv packet sizes at the end of packetsMichael Niedermayer2015-10-14
| | | | | | | In one case it was written as zero, one case left it uninitialized, missed the 11 bytes for the flv header. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* mimic: drop AVPicture usagewm42015-10-14
| | | | | | | Work on the AVFrame references directly. Instead of setting up a flipped/swapped "view" on the pictures, flip/swap them when returning decoded frames to the API user.
* libschroedinger: Properly use AVFrame APIVittorio Giovara2015-10-14
| | | | | | | | Rather than copying data buffers around, allocate a proper frame, and use the standard AVFrame functions. This effectively makes the decoder capable of direct rendering. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>
* qtrle: Properly use AVFrame APIVittorio Giovara2015-10-14
| | | | | | | Rather than copying data buffers around, just add a reference to the current frame. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>

* build: add Solaris symbol versioningSean McGovern2015-10-11
| | | | | | | | | | | | | | | | | | The versioning facility in the Solaris linker differs from Linux in 3 ways: 1. It does not support globs in linker scripts for symbol versioning -- this is a GNU extension. 2. The linker argument is '-M', instead of '--version-script'. 3. It is picky about line endings. Each symbol or directive must be on a line of it's own. Let's use make_sunver.pl from GCC to generate a version script that works correctly with the Solaris linker. It's function is to correctly expand the globs in the original generated version script. 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

* 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

* 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
