* qpeg: use reget_buffer() in decode_frame()Stefano Sabatini2011-04-27
| | | | | | | | | | | Decoder relies on previous frame data, so use reget_buffer(). This also set frame->reference to 3, as the frame will be requested unmodified later so it shouldn't be modified by the application. Fix playback of file Clock.avi. Signed-off-by: Ronald S.

* smacker: remove unnecessary call to avctx->release_buffer in decode_frame()Stefano Sabatini2011-04-27
| | | | | | | | | The release_buffer was cleaning the provided frame, thus causing the successive call to avctx->reget_buffer() to allocate a new frame. In case the returned frame was not the same one previously returned but a new one with different data, it resulted in artifacts. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>

* lavc: deprecate FF_*_TYPE macros in favor of AV_PICTURE_TYPE_* enumsStefano Sabatini2011-04-26
| | | | | | | | | | | | Also deprecate av_get_pict_type_char() in favor of av_get_picture_type_char(). The new enum and av_get_picture_type_char() are defined in libavutil. This allows the use in libavfilter without the need to link against libavcodec. Signed-off-by: Stefano Sabatini <stefano.sabatini-lala@poste.it> Signed-off-by: Anton Khirnov <anton@khirnov.net>

* fade: fix draw_slice() check on fade->factor valueMark Himsley2011-04-25
| | | | | | | | | | draw_slice() checks that the fade factor is < 65536 and only calculates the fade if so. But the fade factor is clipped in end_frame() by av_clip_uint16() to 65535, so the fade is calculated for every frame. This patch alters the check so that it compares with < 65535 (UINT16_MAX).

* fade: make draw_slice() chroma check against planes 1 and 2Mark Himsley2011-04-25
| | | | | | | | draw_slice() checks that planes 0 and 1 of AVFilterBufferRef's data are not NULL before manipulating planes 1 and 2. This patch makes the check against planes 1 and 2. More senseful and possibly more robust. Signed-off-by: Anton Khirnov <anton@khirnov.net>

* read AVI palette from the end of extradataKostya Shishkov2011-04-24
| | | | | | | | | | | | | | | | | | Official AVI specification says that stream header in case of video contains BITMAPINFO, which is equal to BITMAPINFOHEADER and optional palette. Currently lavf AVI demuxer thinks otherwise which produces garbage on codecs that have both palette and extradata (luckily, there are not so many such codecs). An example of such file is: http://samples.multimedia.cx/V-codecs/KMVC/baseball1.avi (IIRC, MSS1 or MSS2 also had such situation but they are still not supported by lavc). As a side note, passing palette in extradata as it's been done previously is not quite correct since proper _extra_ data is surplus bytes in BITMAPINFOHEADER, not including palette.

* applehttp: Don't export variant_bitrate if it isn't knownMartin Storsjö2011-04-24
| | | | | | | | If there are no variants, the total bitrate of the single stream isn't known, and exporting variant_bitrate = 0 does look weird, since there really aren't any variants. Signed-off-by: Martin Storsjö <martin@martin.st>

* Handle unicode file names on windowsKirill Gavrilov2011-04-24
| | | | | | | | | | | | | All file names should be in UTF-8 within libavformat. This is handled by mapping the open() function to an internal one in os_support.h for windows. fopen() could be overridden in the same way, but if that would be used from ffmpeg.c, it would add a dependency on an ff prefixed internal lavf function.

* patcheck: Allow overiding grep program(s) through environment variables.Brad2011-04-23
| | | | | | | patcheck hardcodes the binary names for grep/egrep. This makes overriding the binary names a pain, e.g. when calling a GNU version of grep on BSD systems. Signed-off-by: Diego Biurrun <diego@biurrun.de>
