Paul B Mahol	5d8879208c	avfilter/vf_pseudocolor: add cool preset	1 year ago
Paul B Mahol	c183f840fa	avfilter/af_axcorrelate: add another algorithm for calculation Rewrite EOF logic while here.	1 year ago
Anton Khirnov	acde0ae6c7	doc/ffmpeg: fix -enc_time_base documentation Stop claiming the argument is always a floating point number, which * confuses floating point and decimal numbers * is not always true even accounting for the above point	1 year ago
Anton Khirnov	dff3a283cd	fftools/ffmpeg: rework -enc_time_base handling Read the timebase from FrameData rather than the input stream. This should fix #10393 and generally be more reliable. Replace the use of '-1' to indicate demuxing timebase with the string 'demux'. Also allow to request filter timebase with '-enc_time_base filter'.	1 year ago
Anton Khirnov	f264204de9	lavc: deprecate AV_CODEC_FLAG_DROPCHANGED This decoding flag makes decoders drop all frames after a parameter change, but what exactly constitutes a parameter change is not well defined and will typically depend on the exact use case. This functionality then does not belong in libavcodec, but rather in user code	1 year ago
Paul B Mahol	7430ee2b8b	avfilter/avf_showcwt: add rotation option	1 year ago
Anton Khirnov	1b45405d44	tests/fate-run: add testing with a random number of threads Useful for discovering bugs that depend on a specific thread count. Use like THREADS=randomX for a random thread count from 1 to X, with X=16 when not specified. Note that the thread count is different for every test.	1 year ago

Niklas Haas	13e9899014	lavfi/vf_libplacebo: add contrast recovery options New upstream option. Enabled by default in the high-quality preset upstream, so enable it by default here.	1 year ago
Niklas Haas	2e83ba001d	lavfi/vf_libplacebo: deprecate hybrid_mix option Deprecated upstream in libplacebo v6.292.	1 year ago
James Almer	d694c25b44	avutil/random_seed: add av_random_bytes() Uses the existing code for av_get_random_seed() to return a buffer with cryptographically secure random data, or an error if none could be generated. Signed-off-by: James Almer <jamrial@gmail.com>	1 year ago
Devin Heitmueller	ac4247270c	avdevice/decklink_enc: add support for SMPTE 2038 VANC packet output Support decoding and embedding VANC packets delivered via SMPTE 2038 into the SDI output. We leverage an intermediate queue because data packets are announced separately from video but we need to embed the data into the video frame when it is output. Note that this patch has some additional abstraction for data streams in general as opposed to just SMPTE 2038 packets. This is because subsequent patches will introduce support for other data codecs. Thanks to Marton Balint for review/feedback.

Paul B Mahol	ea190b8a23	avfilter/vf_drawtext: use flags type of option for text_align	1 year ago
yethie	01420316d2	avfilter/vf_drawtext: add support for commands	1 year ago
yethie	692d37d2e9	avfilter/vf_drawtext: add y_align option The new y_align option specifies if the user provided y value is referred to the top of the text, to the font baseline or to the top of the font	1 year ago
yethie	5f2d907de2	avfilter/vf_drawtext: implement text alignment Text can now be aligned vertically (top, middle, bottom) and horizontally (left, center, right) relative to the background box.	1 year ago
yethie	01d843f6d0	avfilter/vf_drawtext: add expression variables to control font ascent/descent The following new variables can be used in the x and y expressions: font_a, font_d, top_a, bottom_d.	1 year ago

yethie	1eeb59a209	avfilter/vf_drawtext: improve glyph shaping and positioning - text is now shaped using libharfbuz - glyphs position is now accurate to 1/4 pixel in both directions - the default line height is now the one defined in the font Adds libharfbuzz dependency.	1 year ago

Philip Langdale	73a2252f1d	avfilter/vf_bwdif_cuda: CUDA accelerated bwdif deinterlacer I've been sitting on this for 3 1/2 years now(!), and I finally got around to fixing the loose ends and convincing myself that it was correct. It follows the same basic structure as yadif_cuda, including leaving out the edge handling, to avoid expensive branching.	1 year ago
Dawid Kozinski	3069a8fe3c	avformat/evc_muxer: Added muxer to handle writing EVC encoded data into file or output bytestream - Provided AVOutputFormat structure describing EVC output format (ff_evc_muxer) - Added documentation for EVC muxer Signed-off-by: Dawid Kozinski <d.kozinski@samsung.com>	1 year ago

Anton Khirnov	811b0e02be	doc/examples/transcode: stop using decoder's AVCodecContext.time_base The contents of this field are not defined for decoding. Use pkt_timebase, which is the timebase of demuxed packets. Drop a tautological av_packet_rescale_ts() call, as the stream and decoder timebases are the same.	1 year ago
Anton Khirnov	828d3b4432	doc/examples/transcode: set packet timebase for decoding It is recommended for callers to set it, though not required.	1 year ago
