This means that 721 all subtitles text decoders currently still output ASS with timings printed 722 as strings in the AVSubtitles.rects[N]->ass fields. 723 724 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS 725 timing is limited to a 1/100 time base, so this is relevant for any subtitles 726 format needing a bigger one), ease timing adjustments, and prevents the need 727 of removing the timing from the decoded string yourself. This form is also 728 known as "the Matroska form". The timing information (start time, duration) 729 can be found in the AVSubtitles fields. 730 7312016-02-24 - 7e49cdd / 7b3214d0 - lavc 57.25.100 / 57.13.0 - avcodec.h 732 Add AVCodecContext.hw_frames_ctx. 733 7342016-02-24 - 1042402 / b3dd30d - lavfi 6.36.100 / 6.2.0 - avfilter.h 735 avfilter.h - Add AVFilterLink.hw_frames_ctx. 736 buffersrc.h - Add AVBufferSrcParameters and functions for handling it. 737 7382016-02-23 - 14f7a3d - lavc 57.25.100 739 Add AV_PKT_DATA_MPEGTS_STREAM_ID for exporting the MPEGTS stream ID. 740 7412016-02-18 - 08acab8 - lavu 55.18.100 - audio_fifo.h 742 Add av_audio_fifo_peek_at(). 743 7442016-xx-xx - lavu 55.18.100 / 55.6.0 745 26abd51 / 721a4ef buffer.h - Add av_buffer_pool_init2(). 746 1a70878 / 89923e4 hwcontext.h - Add a new installed header hwcontext.h with a new API 747 for handling hwaccel frames. 748 6992276 / ad884d1 hwcontext_cuda.h - Add a new installed header hwcontext_cuda.h with 749 CUDA-specific hwcontext definitions. 750 d779d8d / a001ce3 hwcontext_vdpau.h - Add a new installed header hwcontext_vdpau.h with 751 VDPAU-specific hwcontext definitions. 752 63c3e35 / 7bc780c pixfmt.h - Add AV_PIX_FMT_CUDA. 753 754-------- 8< --------- FFmpeg 3.0 was cut here -------- 8< --------- 755 7562016-02-10 - bc9a596 / 9f61abc - lavf 57.25.100 / 57.3.0 - avformat.h 757 Add AVFormatContext.opaque, io_open and io_close, allowing custom IO 758 7592016-02-01 - 1dba837 - lavf 57.24.100 - avformat.h, avio.h 760 Add protocol_whitelist to AVFormatContext, AVIOContext 761 7622016-01-31 - 66e9d2f - lavu 55.17.100 - frame.h 763 Add AV_FRAME_DATA_GOP_TIMECODE for exporting MPEG1/2 GOP timecodes. 764 7652016-01-01 - 5e8b053 / 2c68113 - lavc 57.21.100 / 57.12.0 - avcodec.h 766 Add AVCodecDescriptor.profiles and avcodec_profile_name(). 767 7682015-12-28 - 1f9139b - lavf 57.21.100 - avformat.h 769 Add automatic bitstream filtering; add av_apply_bitstream_filters() 770 7712015-12-22 - 39a09e9 - lavfi 6.21.101 - avfilter.h 772 Deprecate avfilter_link_set_closed(). 773 Applications are not supposed to mess with links, 774 they should close the sinks. 775 7762015-12-17 - lavc 57.18.100 / 57.11.0 - avcodec.h dirac.h 777 xxxxxxx - Add av_packet_add_side_data(). 778 xxxxxxx - Add AVCodecContext.coded_side_data. 779 xxxxxxx - Add AVCPBProperties API. 780 xxxxxxx - Add a new public header dirac.h containing 781 av_dirac_parse_sequence_header() 782 7832015-12-11 - 676a93f - lavf 57.20.100 - avformat.h 784 Add av_program_add_stream_index() 785 7862015-11-29 - 93fb4a4 - lavc 57.16.101 - avcodec.h 787 Deprecate rtp_callback without replacement, i.e. it won't be possible to 788 get image slices before the full frame is encoded any more.

These new functions take an AVPacket *pkt 3191 argument instead of a const uint8_t *buf / int buf_size pair. 3192 31932009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space() 3194 Introduce the av_fifo_space() function. 3195 31962009-04-02 - fabd246 - lavc 52.23.0 - AVPacket 3197 Move AVPacket declaration from libavformat/avformat.h to 3198 libavcodec/avcodec.h. 3199 32002009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats 3201 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR, 3202 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values. 3203 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and 3204 PIX_FMT_BGR32_1 are now macros. 3205 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases. 3206 Re-sort the enum PixelFormat list accordingly. 3207 This change breaks API/ABI backward compatibility. 3208 32092009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants 3210 Add the enum PixelFormat values: 3211 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE, 3212 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE. 3213 32142009-03-21 - ee6624e - lavu 50.0.0 - av_random* 3215 The Mersenne Twister PRNG implemented through the av_random* functions 3216 was removed.
