When B-frame is enabled, encoder seems to adjust PTS of encoded sample by using frame duration. For instance, one observed timestamp pattern by using B-frame enabled and 30fps stream is: * Frame-1: MF pts 0:00.033333300 MF dts 0:00.000000000 * Frame-2: MF pts 0:00.133333300 MF dts 0:00.033333300 * Frame-3: MF pts 0:00.066666600 MF dts 0:00.066666600 * Frame-4: MF pts 0:00.099999900 MF dts 0:00.100000000 We can notice that the amount of PTS shift is frame duration and Frame-4 exhibits PTS < DTS. To compensate shifted timestamp, we should calculate the timestamp offset and re-calculate DTS correspondingly. Otherwise, total timeline of output stream will be shifted, and that can cause time sync issue. Part-of: <https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/-/merge_requests/2354> |
