Jernej Fijacko f86f213a6d avcodec/dvbsub: add support for Display Definition Segment to DVB Subtitle encoder Current version of dvbsub encoder doesn't support HD DVB subtitles. The high resolution bitmaps are muxed into the stream but without the DDS (display definition segment) the players asume that the DVB subtitles are in SD (720x576) resolution which causes them to either render the subtitles too large and misplaced or don't render them at all. By including the DDS as defined in section 7.7.1 of ETSI EN 300 743 (V1.3.1) this problem is fixed. 7.2.1 Display definition segment The display definition for a subtitle service may be defined by the display definition segment if present in the stream. Absence of a DDS implies that the stream is coded in accordance with EN 300 743 (V1.2.1) [5] and that a display width of 720 pixels and a display height of 576 lines may be assumed. https://www.etsi.org/deliver/etsi_en/300700_300799/300743/01.03.01_60/en_300743v010301p.pdf Signed-off-by: Jernej Fijacko <mikrohard@gmail.com> Signed-off-by: Marton Balint <cus@passwd.hu>		6 years ago

FFmpeg README

FFmpeg is a collection of libraries and tools to process multimedia content such as audio, video, subtitles and related metadata.

Libraries

libavcodec provides implementation of a wider range of codecs.
libavformat implements streaming protocols, container formats and basic I/O access.
libavutil includes hashers, decompressors and miscellaneous utility functions.
libavfilter provides a mean to alter decoded Audio and Video through chain of filters.
libavdevice provides an abstraction to access capture and playback devices.
libswresample implements audio mixing and resampling routines.
libswscale implements color conversion and scaling routines.

Tools

ffmpeg is a command line toolbox to manipulate, convert and stream multimedia content.
ffplay is a minimalistic multimedia player.
ffprobe is a simple analysis tool to inspect multimedia content.
Additional small tools such as aviocat, ismindex and qt-faststart.
