Seeking in Opus file with ffprobe/ffplay everything seems work fine. PTS
changes correctly and all works as expected.
Scenario when one wants to seek to X PTS in file and then read Y bytes
after that jump Y bytes ahead to read next Y bytes one gets the same
output as first readied Y bytes.
If you just keep doing that reading procedure after next Z times you just
get new loop to read on. This bug somehow follows the OggS-headers and
granule points in Ogg-container. It seems you always got Y bytes from
start of the last header-point. On Ogg/Vorbis with or without libvorbis
everything works with same code.

demo this bug report.
