[FFmpeg-devel] first_dts set to RELATIVE_TS_BASE in vorbis audio

In recent builds I now see that the AVStream.first_dts is set to RELATIVE_TS_BASE which is 0x7ffeffffffffffff.

RELATIVE_TS_BASE is defined in libavformat\utils.c

Not sure what all this effects, but I am seeing it in ogg files with vorbis audio for the audio stream.

Previously, the first_dts value was always reliable in that it was set correctly or it contained AV_NOPTS_VALUE.

Is this a bug or what does it mean ?
