* binkaudio: remove unneeded GET_BITS_SAFE macroJustin Ruggles2012-09-181-12/+5
| | | | Normal get_bits() already has overread protection.
* binkaudio: use float sample formatJustin Ruggles2012-09-181-35/+21
| | | | Use planar for DCT codec, interleaved for RDFT codec.
* binkaudio: use a different value for the coefficient scale for the DCT codecJustin Ruggles2012-09-181-4/+4
| | | | Eliminates the need for vector_fmul_scalar() in each frame.
* flvenc: silence bogus warningBenjamin Larsson2012-09-181-1/+1
| | | | | | | | | The compiler fails to figure out that enc->codec_type can only have 3 different values. Thus when an if/else is encountered it triggers on the possibility of the else case has not initialized the flags variable. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* configure: include flags in nm variableMans Rullgard2012-09-171-5/+5
| | | | | | | This simplifies ensuring proper flags are used when the default is overridden by the system or on the command line. Signed-off-by: Mans Rullgard <mans@mansr.com>

| | | | | | | | | | | ALS spec: 11.6.3.1.1 Quantization and encoding of parcor coefficients ... In all cases the resulting quantized values ak are restricted to the range [-64,63].

| | | | | | | | | | | Fixes out of array write in quant_cof. Also make sure no invalid opt_order stays in the context.

* avfiltergraph: silence an uninitialized variable warningAnton Khirnov2012-09-171-1/+2
| | | | | | | | | | The warning is: libavfilter/avfiltergraph.c: In function ‘avfilter_graph_config’: libavfilter/avfiltergraph.c:528:9: warning: ‘best_idx’ may be used uninitialized in this function [-Wuninitialized] libavfilter/avfiltergraph.c:479:13: note: ‘best_idx’ was declared here Initialize it to an invalid value and add an assert that it's properly set later.
* xsubenc: reindentAnton Khirnov2012-09-171-6/+6

* lavc: replace AVCodecContext.encode with subtitle-specific callbackAnton Khirnov2012-09-176-16/+18
| | | | | AVCodecContext.encode is currently used only for subtitles, encode2 is used for audio and video.
* lavc: add const to private codec class initialization.Anton Khirnov2012-09-171-1/+1
| | | | Silences a warning about discarding const.
* avconv: don't pass a bogus parameter to avfilter_graph_create_filter().Anton Khirnov2012-09-171-1/+1
| | | | | | The buffer sink does not take any parameters. Fixes an uninitialized variable warning.
* id3v2: strdup the genre name explicitly.Clément Bœsch2012-09-171-7/+4
| | | | | | | | | It would have been done anyway in the av_dict_set() call. This simplifies the code and avoid a warning because of assigning a const string from ff_id3v1_genre_str to a non-const variable. Signed-off-by: Anton Khirnov <anton@khirnov.net>
* lavf/id3v2: do not export empty fields.Clément Bœsch2012-09-171-0/+2
| | | | | | This also avoids a memleak. Signed-off-by: Anton Khirnov <anton@khirnov.net>
* buffersrc: add const to the AVFrame* argument of av_buffersrc_write_frame()Anton Khirnov2012-09-172-2/+2

* avconv: flush filtered frames before reconfiguring filtersJanne Grunau2012-09-171-0/+4
| | | | This prevents lost frames after a resolution change.
* mov: stsd entries must be at least 16 byteMichael Niedermayer2012-09-161-1/+4
| | | | | | | | | | Fix near infinite loop in stsd parsing. Bug found by: Diana Elena Muscalu The size is unsigned according the specification. Signed-off-by: Michael Niedermayer <michaelni@gmx.at> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>

* mpegvideo: drop unnecessary arguments to hpel_motion()Mans Rullgard2012-09-161-24/+15
| | | | | | | These arguments are either constants or copies of MpegEncContext fields just as easily accessed within the function. Signed-off-by: Mans Rullgard <mans@mansr.com>
* mpegvideo: drop 'inline' from some functionsMans Rullgard2012-09-161-11/+12
| | | | | | | These functions do not benefit from being inlined. They are large, and there are no opportunities for constant propagation. Signed-off-by: Mans Rullgard <mans@mansr.com>
* nellymoserdec: drop support for s16 output.Anton Khirnov2012-09-161-27/+4
| | | | | It internally decodes as float and then converts to s16 by a call to float_to_int16(). The caller can do this just as well by using lavr.
* bmpdec: only initialize palette for pal8.Anton Khirnov2012-09-161-3/+3
| | | | | | | | | Gray8 is not considered to be paletted, so this would cause an invalid write. Fixes bug 367. CC: libav-stable@libav.org
* build: Properly remove object files while cleaningMans Rullgard2012-09-151-0/+3
| | | | | | | Previously, object files in, for example, compat/ were left after a clean or distclean was run. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>

* compat/vsnprintf: return number of bytes required on truncation.Ronald S. Bultje2012-09-151-3/+10
| | | | | | This conforms to C99, but requires Windows >= XP. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>
* avformat: fix typo in avformat_close_inputLuca Barbato2012-09-151-1/+1
| | | | The condition should not be &&.

* mp3enc: downgrade some errors in writing Xing frame to warningsReimar Döffinger2012-09-151-2/+5
| | | | Also clarify the meaning of the log message.
* lavf: flush the output AVIOContext in av_write_trailer().Anton Khirnov2012-09-1519-30/+16
| | | | | | | This is consistent with stdio and is what we want to do in all cases. Fixes a bug in the voc muxer which didn't flush in write_trailer() previously. This is the cause of the change in the test results.
* lavf: cosmetics, reformat av_write_trailer().Anton Khirnov2012-09-151-8/+8
|
* avio: flush the internal buffer in avio_close()Stefano Sabatini2012-09-154-3/+5
| | | | | This is consistent with stdio, and thus what people would naturally expect.

* configure: x86: improve ebp availability checkMans Rullgard2012-09-141-1/+4
| | | | | | | | Some compilers are extra strict about register usage in main(), disallowing ebp in inline asm there while allowing it elsewhere. This change makes the test better reflect actual usage. Signed-off-by: Mans Rullgard <mans@mansr.com>
* vorbisdec: ensure FASTDIV denominator is never 1Luca Barbato2012-09-141-3/+2
| | | | | | | | | | In both usages of FASTDIV the denominator might be 1. Using a branch could make the function slower than using a normal division. Both denominator and numerator can be multiplied by 2 safely and using shifts is faster than using a branch.
* avformat: refactor avformat_close_inputLuca Barbato2012-09-141-4/+13
| | | | Do not crash if the input format is not allocated yet.
* avformat: simplify avformat_close_inputLuca Barbato2012-09-141-2/+2
| | | | avio_close checks by itself for NULL condition.

* trasher: Include all the necessary headersMartin Storsjö2012-09-131-0/+2
| | | | | | | The missing headers are required for errno and for strerror. This fixes building of this tool on mingw32ce. Signed-off-by: Martin Storsjö <martin@martin.st>
