Michael Niedermayer: * Main merge operation, notably avfilter.c and video.c * Switch to AVFrame: - afade - anullsrc - apad - aresample - blackframe - deshake - idet - il - mandelbrot - mptestsrc - noise - setfield - smartblur - tinterlace * various merge changes and fixes in: - ashowinfo - blackdetect - field - fps - select - testsrc - yadif Nicolas George: * Switch to AVFrame: - make rawdec work with refcounted frames. Adapted from commit 759001c534287a96dc96d1e274665feb7059145d by Anton Khirnov. Also, fix the use of || instead of | in a flags check. - make buffer sink and src, audio and video work all together Clément Bœsch: * Switch to AVFrame: - aevalsrc - alphaextract - blend - cellauto - colormatrix - concat - earwax - ebur128 - edgedetect - geq - histeq - histogram - hue - kerndeint - life - movie - mp (with the help of Michael) - overlay - pad - pan - pp - pp - removelogo - sendcmd - showspectrum - showwaves - silencedetect - stereo3d - subtitles - super2xsai - swapuv - thumbnail - tile Hendrik Leppkes: * Switch to AVFrame: - aconvert - amerge - asetnsamples - atempo - biquads Matthieu Bouron: * Switch to AVFrame - alphamerge - decimate - volumedetect Stefano Sabatini: * Switch to AVFrame: - astreamsync - flite - framestep Signed-off-by: Michael Niedermayer <michaelni@gmx.at> Signed-off-by: Nicolas George <nicolas.george@normalesup.org> Signed-off-by: Clément Bœsch <ubitux@gmail.com> Signed-off-by: Hendrik Leppkes <h.leppkes@gmail.com> Signed-off-by: Matthieu Bouron <matthieu.bouron@gmail.com> Signed-off-by: Stefano Sabatini <stefasab@gmail.com> Merged-by: Michael Niedermayer <michaelni@gmx.at>
