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>

avfilter: Replace query_formats callback with union of list and callback If one looks at the many query_formats callbacks in existence, one will immediately recognize that there is one type of default callback for video and a slightly different default callback for audio: It is "return ff_set_common_formats_from_list(ctx, pix_fmts);" for video with a filter-specific pix_fmts list. For audio, it is the same with a filter-specific sample_fmts list together with ff_set_common_all_samplerates() and ff_set_common_all_channel_counts(). This commit allows to remove the boilerplate query_formats callbacks by replacing said callback with a union consisting the old callback and pointers for pixel and sample format arrays. For the not uncommon case in which these lists only contain a single entry (besides the sentinel) enum AVPixelFormat and enum AVSampleFormat fields are also added to the union to store them directly in the AVFilter, thereby avoiding a relocation. The state of said union will be contained in a new, dedicated AVFilter field (the nb_inputs and nb_outputs fields have been shrunk to uint8_t in order to create a hole for this new field; this is no problem, as the maximum of all the nb_inputs is four; for nb_outputs it is only two). The state's default value coincides with the earlier default of query_formats being unset, namely that the filter accepts all formats (and also sample rates and channel counts/layouts for audio) provided that these properties agree coincide for all inputs and outputs. By using different union members for audio and video filters the type-unsafety of using the same functions for audio and video lists will furthermore be more confined to formats.c than before. When the new fields are used, they will also avoid allocations: Currently something nearly equivalent to ff_default_query_formats() is called after every successful call to a query_formats callback; yet in the common case that the newly allocated AVFilterFormats are not used at all (namely if there are no free links) these newly allocated AVFilterFormats are freed again without ever being used. Filters no longer using the callback will not exhibit this any more.
