* pthread: Fix deadlock during thread initializationDerek Buitenhuis2013-10-13
| | | | | | | | | | Sometimes, if pthread_create() failed, then pthread_cond_wait() could accidentally be called in the worker threads after the uninit function had already called pthread_cond_broadcast(), leading to a deadlock. Don't call pthread_cond_wait() if c->done is set. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>

* vp6: Support cropping to AVCodecContext.width/heightMartin Storsjö2013-10-10
| | | | | | | | | | | | In these cases, there is no extradata but only the properly set width/height values by the demuxer. This makes sure VP6 in F4V files is cropped properly. This is similar to what is done for H264 for letting the container width/height override what's in the bitstream, since 30f515091. Signed-off-by: Martin Storsjö <martin@martin.st>

* x86inc: Utilize the shadow space on 64-bit WindowsHenrik Gramner2013-10-07
| | | | | | | | | Store XMM6 and XMM7 in the shadow space in functions that clobbers them. This way we don't have to adjust the stack pointer as often, reducing the number of instructions as well as code size. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>
* x86: fdct: Employ more specific ifdefsDiego Biurrun2013-10-06
| | | | This avoids building mmxext and sse2 code when disabled by configure.
* x86: dsputil: Separate ff_add_hfyu_median_prediction_cmov from dsputil_mmxDiego Biurrun2013-10-05
| | | | | The function does not depend on MMX and compilation without MMX enabled fails if the function is compiled conditional on MMX availability.

* x86: xviddct: Employ more specific ifdefsDiego Biurrun2013-10-05

* rpza: Fix a buffer size checkMartin Storsjö2013-09-29
| | | | | | | | | We read 2 bytes for 15 out of 16 pixels, therefore we need to have at least 30 bytes, not 16. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>

* pcx: Consume the whole packet if giving up due to missing paletteMartin Storsjö2013-09-29
| | | | | | | | | Previously, we returned 0, meaning successful decoding but 0 bytes consumed, leading to an infinite loop. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>
* pngdec: Stop trying to decode once inflate returns Z_STREAM_ENDMartin Storsjö2013-09-29
| | | | | | | | | | If the input buffer contains more data after the deflate stream, the loop previously left running infinitely, with inflate returning Z_STREAM_END.
