--- Comment #1 from Tim-Philipp Müller <t.i.m at zen.co.uk> ---
I think oggdemux should always be able to calculate a timestamp.
This only happens in reverse playback?
How can one reproduce it?
I've tried:
1)
gst-launch-1.0 videotestsrc num-buffers=250 ! video/x-raw,framerate=10/1 !
timeoverlay font-desc=Sans,25 ! theoraenc keyframe-force=10 ! splitmuxsink
muxer=oggmux max-size-time=5000000000 location=/tmp/ogg-%05d.ogv
2)
gst-play-1.0 splitfile:///tmp/ogg-*ogv
- let play a little
- press '-' repeatedly to lower playback speed
- press 'd' to reverse playback direction
Result: I don't see any problems or skips in the timestamps when crossing file
boundaries
