jiangjie f606872ed0 avformat/dashdec: The segments in dash file doesn't read completely when segment's size and duration is very small. 
If the segment is very small, avformat_find_stream_info
will read all audio/video data in this segment.
cur->is_restart_needed is set to 0 later in dash_read_packet,
and no chance to be set to 1 again in the read_data function.

Reproduction:
ffmpeg -f lavfi -i mandelbrot -f lavfi -i anullsrc -c:v vp8 \
 -g 5 -r 5 -c:a libopus -use_template 0 -seg_duration 1 \
 -t 15 -y test_720.mpd
ffprobe -show_packets test_720.mpd

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 means to alter decoded audio and video through a directed graph of connected 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.

Documentation
