* replaygain: allow exporting already decoded replaygain valuesAlessandro Ghedini2014-04-17
| | | | | | | | This adds a function to export raw replaygain values (i.e. in the (u)int32_t form). It first checks whether AV_PKT_DATA_REPLAYGAIN side data is present, in which case it does nothing. Signed-off-by: Anton Khirnov <anton@khirnov.net>
* resample: remove an unneeded context variableAnton Khirnov2014-04-17

* drawtext: Add fontconfig supportLuca Barbato2014-04-17
| | | | | | Introduce the `font` option and make it optional to pass a fontfile. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* vp78: Align the intra4x4_pred_mode_top array within VP8MacroblockMartin Storsjö2014-04-14
| | | | | | | | This array is written using AV_WN32A, assuming alignment. This hopefully fixes the failing vp7 fate test on sparc. Signed-off-by: Martin Storsjö <martin@martin.st>
* dcadec: Delete redundant init_get_bits callNiels Möller2014-04-14
| | | | | | | | No initialization is needed in dca_decode_frame, because the next thing it does is calling dca_parse_frame_header, which takes care of the needed initialization. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* rtmpproto: Handle RTMP chunk size packets before the connect packetStephan Soller2014-04-14
| | | | | | | | | | | | | In all other cases where ff_rtmp_packet_read is used, the packet returned is passed to rtmp_parse_result more or less immediately. In this single case, the content of the packet was required to be a connect packet. Some clients, e.g. Open Broadcaster Software, send a chunk size packet before the connect packet. If the first packet is a chunk size packet, handle it and read another one, requiring this to be a connect packet instead. Signed-off-by: Martin Storsjö <martin@martin.st>
* rtmpproto: Make sure to pass on the error code if read_connect failedMartin Storsjö2014-04-14
| | | | | | | | | Previously, if read_connect failed, the ret variable was unmodified and had the value 0, indicating success, which then was returned from the rtmp_open function, even though it actually failed. CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>
* x86/synth_filter: remove the fma3 version ifdefsJames Almer2014-04-13
| | | | | | | This fixes compilation failures with --disable-fma3 Signed-off-by: James Almer <jamrial@gmail.com> Signed-off-by: Anton Khirnov <anton@khirnov.net>
* af_volume: implement replaygain clipping preventionAlessandro Ghedini2014-04-13
| | | | | | | This adds a new "replaygain_noclip" option to the filter, and, if enabled, limits the gain applied for tracks where clipping would occur. Signed-off-by: Anton Khirnov <anton@khirnov.net>
* lavr: allocate the resampling buffer with a positive sizeAnton Khirnov2014-04-13
| | | | | | This fixes cases where very few input samples (fewer than needed for one output sample) are passed to lavr at the beginning. CC:libav-stable@libav.org
* FATE: add tests for more resampling modesAnton Khirnov2014-04-13

* resample: implement flushingAnton Khirnov2014-04-13

* dcadec: Use correct channel count in stereo downmix checkTim Walker2014-04-12
| | | | | | | s->prim_channels is greater than num_core_channels when an XCh extension is present in the bitstream. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* dcadec: Do not decode the XCh extension when downmixing to stereoTim Walker2014-04-12
| | | | | | This is neither necessary nor currently supported. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>

* tiffdec: remove an unneeded variableJustin Ruggles2014-04-12

* tiff: use a better name and enum values for PhotometricInterpretationJustin Ruggles2014-04-12
| | | | Also add additional known values and log as missing features.
* tiffdec: use a single strip if RowsPerStrip is 0Justin Ruggles2014-04-12
| | | | | The spec does not specify that 0 is an error condition, and there are samples which use 0 when the whole image is in one strip.
* tiffdec: use bytestream2 to simplify overread/overwrite protectionJustin Ruggles2014-04-12
| | | | | | Based on a patch by Paul B Mahol <onemda@gmail.com> CC:libav-stable@libav.org
* bytestream: add bytestream2_copy_buffer() functionsJustin Ruggles2014-04-12
| | | | | | | This is basically an overread/overwrite-safe memcpy between a GetByteContext and a PutByteContext. CC:libav-stable@libav.org

| | | | | | | | | Fixes conversion of pal8 to rgb formats with alpha. Updated references for 2 FATE tests which previously encoded fully transparent images. Based on a patch by Baptiste Coudurier <baptiste.coudurier@gmail.com>

* doc: Libavfilter English cleanupKaterina Barone-Adesi2014-04-12
| | | | | | | | | This aims to standardize the English used in the libavfilter documentation, describing the same thing in the same way more often, and significantly reduce the amount of outright errors, including run-on sentences and sentence fragments.

* mp3enc: Properly write bitrate value in XING headerMichael Niedermayer2014-04-12
| | | | | | | | | | | | Instead of using a fixed bitrate_idx, calculate a matching bitrate for the XING header. Using a fixed bitrate_idx causes tools such as file(1) and mediainfo(1) to report wrong bitrate and bitrate mode when using CBR.

| | | | | | | | The correct "next" input sample is not the first sample of the resampling buffer, but the center sample of the filter_length-sized block at the beginning. CC:libav-stable@libav.org

* mpegvideo: operate with pointers to AVFrames instead of whole structswm42014-04-09
| | | | | | | | | | | | | The most interesting parts are initialization in ff_MPV_common_init() and uninitialization in ff_MPV_common_end(). ff_mpeg_unref_picture and ff_thread_release_buffer have additional NULL checks for Picture.f, because these functions can be called on uninitialized or partially initialized Pictures. NULL pointer checks are added to ff_thread_release_buffer() stub function. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>
