Kevin LaFlamme 7d1464721e dashenc: Write out DASH manifest immediately in streaming mode
When streaming mode is enabled with fMP4/CMAF for DASH output, the
segment files are available to read by players as soon as the first byte
is written instead of only after the file is fully written. The DASH
manifest currently only gets written when the final write to the segment
file occurs. This means that players cannot stream the first segment
while it is being written.

When -lhls is enabled with MP4 segments the HLS manifest is written
immediately to advertise the in-flight segments. This change adds the
same behavior for the DASH manifest so players can stream it
immediately.

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.
