| | | | | This should allow using more complex allocators than simple malloc wrappers.

* arm: add a cpu flag for the VFPv2 vector modeJanne Grunau2015-12-14
| | | | | | | | | | | | | | The vector mode was deprecated in ARMv7-A/VFPv3 and various cpu implementations do not support it in hardware. Vector mode code will depending the OS either be emulated in software or result in an illegal instruction on cpus which does not support it. This was not really problem in practice since NEON implementations of the same functions are preferred. It will however become a problem for checkasm which tests every cpu flag separately. Since this is a cpu feature newer cpu do not support anymore the behaviour of this flag differs from the other flags. It can be only activated by runtime cpu feature selection.

* dict: Change return type of av_dict_copy()Vittorio Giovara2015-10-12
| | | | | | av_dict_set() could return an error, so forward it appropriately. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>
* lavu: Deprecate AVFrame.error[]Vittorio Giovara2015-09-30
| | | | | | | | | | | 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.

* log: Print a full backtrace along with error messages under ValgrindVittorio Giovara2015-04-20
| | | | | | | | Useful to understand where and in what execution state a certain message is generated. It is enabled only when optimizations are disabled, since function names are not printed otherwise. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>
* log: Introduce a more verbose debug levelVittorio Giovara2015-04-19
| | | | And deprecate av_dlog macro.
* parseutils: Make av_small_strptime publicLuca Barbato2015-04-07
| | | | | | And use it in libavformat. Based on a similar patch by Stefano Sabatini <stefasab@gmail.com>.

| | | | | | Based on a patch by Rodger Combs. Signed-off-by: Anton Khirnov <anton@khirnov.net>
* mov: Write the display matrix in orderVittorio Giovara2015-03-23
| | | | | | | | | | This will allow to copy the matrix as is and it is just cleaner to keep the matrix in the same order specified by the mov standard (which is also explicitly described in the documentation). In order to preserve compatibility, flip the angle sign in the display API av_display_rotation_set() and av_display_rotation_get(), and improve the documentation mentioning the rotation direction.
* pixfmt: add a pixel format for QSV hwaccelAnton Khirnov2015-02-19

* Add a side data type for audio service type.Anton Khirnov2015-01-27
| | | | | Currently, audio service type is a field in AVCodecContext. However, side data is more appropriate for this kind of information.

* imgutils: create misc functions for dealing with buffersStefano Sabatini2015-01-14
| | | | | | | | | | | | | | | | | Move the lavc/imgconvert functions and rename them as follows: avpicture_get_size -> av_image_get_buffer_size() avpicture_fill -> av_image_fill_arrays() avpicture_layout -> av_image_copy_to_buffer() The new functions have an align parameter, which allows to define the linesize alignment assumed in the buffer (which is set or read). The names of the functions are consistent with the lavu/samples API (av_samples_get_buffer_size(), av_samples_fill_arrays()). A redundant check has been dropped from av_image_fill_arrays().

* lavu: Add av_gettime_relativeMartin Storsjö2014-10-24
| | | | | | | | | | | | | | | | | | | Since av_gettime() is used in a number of places where actual real time clock is required, the monotonic clock introduced in ebef9f5a5 would have consequences that are hard to handle. Instead split it into a separate function that can be used in the cases where only relative time is desired. On platform where no monotonic clock is available, the difference between the two av_gettime functions is not clear, and one could mistakenly use the relative clock where an absolute one is required. Therefore add an offset, to make it evident that the time returned from av_gettime_relative never is actual current real time, even though it is based on av_gettime. Based on a patch by Olivier Langlois. Signed-off-by: Martin Storsjö <martin@martin.st>
