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
