* texturedsp: Explicitly cast RGBA parameters to unsignedVittorio Giovara2015-11-24
| | | | | Silences warnings when using -Wshift-overflow (GCC 6+). Found-by: James Almer <jamrial@gmail.com>
* texturedspenc: Avoid using separate variablesVittorio Giovara2015-11-24
| | | | Use the result directly, removing an unneeded cast.
* textureencdsp: cosmetics: Use normal static const for tablesVittorio Giovara2015-11-24

* sgi: Correctly propagate meaningful error valuesVittorio Giovara2015-11-24

* sgienc: Support encoding high bit depth images with RLEVittorio Giovara2015-11-24
| | | | Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>
* sgienc: Use a local RLE encoding functionVittorio Giovara2015-11-24
| | | | | | SGI RLE encoding is slighlty different than the one provided by rle module (especially at high bit depth). The pixel count function however does not change, so it is simply made library-public.
* sgienc: Port to bytestream2Vittorio Giovara2015-11-24

* sgienc: Do not end RLE lines with 0sVittorio Giovara2015-11-24
| | | | | | | | This is never mentioned in the specifications, and decoders work just as fine without it. Update the fate references since the compressed file is smaller. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>
* libvpxenc: remove some unused ctrl id mappingsJames Zern2015-11-23
| | | | | | | | | VP8E_UPD_ENTROPY, VP8E_UPD_REFERENCE, VP8E_USE_REFERENCE were removed from libvpx and the remaining values were never used here Reviewed-by: Michael Niedermayer <michael@niedermayer.cc> Signed-off-by: James Zern <jzern@google.com> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* dcadec: Do not check for overreads in auxiliary dataTim Walker2015-11-23
| | | | | | | | The auxiliary data length field is not reliable, and incorrect overread errors could be returned for valid, real-world bitstreams. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* lavc: Deprecate avctx.rtp_callback fieldVittorio Giovara2015-11-20
| | | | | | | | | | | | | | | | | | | | | This function returns the encoded data of a frame, one slice at a time directly when that slice is encoded, instead of waiting for the full frame to be done. However this field has a debatable usefulness, since it looks like it is just a convoluted way to get data at lowest possible latency, or a somewhat hacky way to store h263 in RFC-2190 rtp encapsulation. Moreover when multi-threading is enabled (which is by default) the order of returned slices is not deterministic at all, making the use of this function not reliable at all (or at the very least, more complicated than it should be). So, for the reasons stated above, and being used by only a single encoder family (mpegvideo), this field is deemed unnecessary, overcomplicated, and not really belonging to libavcodec. Libavformat features a complete implementation of RFC-2190, for any other case. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>

* mpegvideo_enc: enable rtp_mode when multiple slices are usedAnton Khirnov2015-11-20
| | | | | | | | | | Currently, multiple slices with just one thread produce corrupted output. Additionally, enable slice structured mode for h263(+) Bug-Id: 912 CC: libav-stabl@libav.org
* mpevideo_enc: disallow multiple slices for h261 and flvAnton Khirnov2015-11-20
| | | | | | They do not work and produce corrupted output. CC: libav-stable@libav.org
* avcodec: Define side data type for fallback trackJohn Stebbins2015-11-18
| | | | | | | | | This side data type is meant to be added to AVStream side data. A fallback track indicates an alternate track to use when the current track can not be decoded for some reason. e.g. no decoder available for codec. Signed-off-by: Anton Khirnov <anton@khirnov.net>

* flacenc: Clamp user-supplied min/max prediction ordersVittorio Giovara2015-11-16
| | | | | | This mimics what the code does internally for default order values. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>
* ffv1: Explicitly name the coder typeVittorio Giovara2015-11-16
| | | | | | | | | | | | | | | | FFv1 uses two types of coders, golomb and range with two different tables. This is exposed this in a rather convoluted way, for example mentioning to set coder type 1 while initializing the variable 'ac' to 2, because encoder does not use range coder with default table. Appropriate internal coder type values have been added and used in any check rather than using raw numbers. Initialization of avctx.coder_type in ffv1dec is removed because this field is encoder only. An unneeded validation check in the encoder is dropped too.

* hqx: correct type and size check of info_offsetAndreas Cadhalpun2015-11-16
| | | | | | | | | It is used as size argument of ff_canopus_parse_info_tag, which uses it as size argument to bytestream2_init, which only supports sizes up to INT_MAX. Changing it's type to unsigned simplifies the check. Signed-off-by: Andreas Cadhalpun <Andreas.Cadhalpun@googlemail.com>
* dds: disable palette flag for compressed imagesAndreas Cadhalpun2015-11-14

* h264_parser: Rename close() to h264_close()Diego Biurrun2015-11-01

* h264: Print the complete user messageVittorio Giovara2015-10-30
| | | | | | | Previously the message was cut off at 256th byte. This will allow dumping the complete x264 encode info when needed. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>
* h264: Print user data SEI under normal debug verbosityVittorio Giovara2015-10-30
| | | | | | Drop the need of setting -debug bugs since it's not a bug, and the message is already under a AV_LOG_DEBUG log level. Instead only print it when there is an actual string in it.
