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.	2 years 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.	2 years ago

yethie	79e39978d8	avfilter/vf_drawtext: extend boxborderw option Adds support for different border size in each direction.	2 years 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.	2 years ago

James Almer	ff7a4cdf04	avcodec/evc_parse: split off deriving PoC Signed-off-by: James Almer <jamrial@gmail.com>	2 years ago
James Almer	f7e0af5edc	avcodec/evc_parser: stop exporting delay and gop_size The former is a property a decoder may export, and the latter is only used in encoding scenarios. Signed-off-by: James Almer <jamrial@gmail.com>	2 years ago

Anton Khirnov	1617d1a752	fftools/ffmpeg: pass subtitle decoder dimensions to sub2video Restores behavior from before `20cacfe493`. Eventually this should be handled similarly to audio/video - with a filtergraph reset or a manual scaler.	2 years ago
Anton Khirnov	88f80977eb	fftools/ffmpeg: use AVFrame to pass subtitles from decoders to filters Allows to use the same buffering code for all media types. Will also be important for the following commit.	2 years ago
Anton Khirnov	fa717baaa5	fftools/ffmpeg_enc: constify the subtitle passed to enc_subtitle()	2 years ago
Anton Khirnov	e89a6d1089	fftools/ffmpeg_dec: move InputStream.prev_sub to Decoder It does not need to be visible outside of decoding code.	2 years ago
Anton Khirnov	a45b9d35b9	fftools/ffmpeg: move fix_sub_duration_heartbeat() to ffmpeg_dec This way ffmpeg.c does not need to access InputStream.prev_sub and it can be made private.	2 years ago
Anton Khirnov	01897c1788	fftools/ffmpeg_dec: move decoding to a separate thread This is only a preparatory step to a fully threaded architecture and does not yet make decoding truly parallel - the main thread will currently submit a packet and wait until it has been fully processed by the decoding thread before moving on. Decoder behavior as observed by the rest of the program should remain unchanged. That will change in future commits after encoders and filters are moved to threads and a thread-aware scheduler is added.	2 years ago
Anton Khirnov	5293adb1a7	fftools/ffmpeg: attach bits_per_raw_sample information to frames This way avoids encoders reaching into filters or decoders for this information.	2 years ago
Anton Khirnov	7d4e00ccf0	fftools/ffmpeg_dec: stop using Decoder.pkt It is only used for flushing the subtitle decoder, so allocate a dedicated packet for that. Keep Decoder.pkt unused for now, it will be repurposed in future commits.	2 years ago
Anton Khirnov	1bdd53e2f9	fftools/ffmpeg_filter: make configure_filtergraph() static It is no longer used outside of ffmpeg_filter.	2 years ago
Anton Khirnov	b1a213ab5d	fftools/ffmpeg_filter: reject filtergraphs with zero outputs Nothing useful can be done with them currently.	2 years ago
Anton Khirnov	a7aa05c599	fftools/ffmpeg_filter: add an AVClass to FilterGraph Use it for logging.	2 years ago
Anton Khirnov	a934392db0	fftools/ffmpeg_enc: move dup_warning global variable to Encoder	2 years ago
Anton Khirnov	1adad44fc7	fftools/ffmpeg_dec: move InputStream.hwaccel_pix_fmt to Decoder It is purely decoder-internal state.	2 years ago
Anton Khirnov	174cb3accf	fftools/ffmpeg_dec: remove pointless InputStream.hwaccel_retrieve_data It is always set to hwaccel_retrieve_data() from ffmpeg_hw.c, so that function can just be called directly instead.	2 years ago
Anton Khirnov	25d96ab6c0	fftools/ffmpeg_hw: inline hwaccel_decode_init() into its caller The function is now trivial and cannot fail, so all error handling in its caller can be removed.	2 years ago
Anton Khirnov	6c9cbf7507	fftools/ffmpeg_demux: reindent after previous commit	2 years ago
Anton Khirnov	98766dbbd7	fftools/ffmpeg_demux: move the loop out of add_input_streams() Make the function process just one input stream at a time and save an indentation level. Also rename it to ist_add() to be consistent with an analogous function in ffmpeg_mux_init.	2 years ago
Anton Khirnov	47a14b542e	tests/fate: add a test for -streamloop with transcoding video+audio	2 years ago
Anton Khirnov	90a26e75a4	tests/fate: rename ffmpeg-streamloop to ffmpeg-streamloop-copy Makes it clear that this tests -streamloop with streamcopy, to distinguish it from further -streamloop tests added in future commits.	2 years ago
Anton Khirnov	df81fb46ee	fftools/ffmpeg_dec: simplify process_subtitle() Its got_output argument always points to 1.	2 years ago
Anton Khirnov	e9eb44ed88	fftools/ffmpeg_dec: drop always-0 InputStream.prev_sub.ret	2 years ago
Anton Khirnov	52d7ea6635	doc/ffmpeg: improve -stats_*_fmt documentation	2 years ago

Zhao Zhili	f66e1862e3	avcodec/videotoolboxenc: inherit profile from AVCodecContext This can happen when user set the avctx->profile field directly instead of specify profile via option. Signed-off-by: Zhao Zhili <zhilizhao@tencent.com>	2 years ago
Zhao Zhili	3fafc842f1	avcodec/videotoolboxenc: remove AUTO_PROFILE define Use FF_PROFILE_UNKNOWN as auto mode. Signed-off-by: Zhao Zhili <zhilizhao@tencent.com>	2 years ago
Zhao Zhili	315c66af0f	avcodec/videotoolboxenc: use int as the type of profile Other than save a few bytes, it also has the benefit to show the AV_OPT_TYPE_CONST value in help, e.g., -profile <int> E..V....... Profile (from 0 to INT_MAX) (default 0) baseline 66 E..V....... Baseline Profile ... Signed-off-by: Zhao Zhili <zhilizhao@tencent.com>	2 years ago
Zhao Zhili	fb85aa959a	avcodec/mediacodecenc: add profile names to options H.264 high10/high422/high44 are unlikely supported by devices. It's there for developers to do the experiment. H.265 main10 works on my device with AV_PIX_FMT_MEDIACODEC. OMX_COLOR_FormatYUV420Planar16 doesn't work. Signed-off-by: Zhao Zhili <zhilizhao@tencent.com>	2 years ago
