-base/tests/examples/playback$ ./playback-test 0 file:///HE_v2_AAC_44kHz_400kbps_ABR_Work_Ya_Body.m4a 

1) start playback
2) seek to middle of file
3) pause
4) open 'seek options'
5) go to speed/rate box entry and change 1.000 to -1.000 and hit Enter
6) press play (reverse playback starts up)

$1 = {mini_object = {type = 6526224, refcount = 1, lockstate = 0, flags = 0, copy = 0x7ffff78de530 <_gst_buffer_copy>, dispose = 0x7ffff78dcca0 <_gst_buffer_dispose>, free = 0x7ffff78dcaa0 <_gst_buffer_free>, n_qdata = 0, qdata = 0x0}, 
  pool = 0x0, pts = 18446744073709551615, dts = 18446744073709551615, duration = 18446744073709551615, offset = 18446744073709551615, offset_end = 18446744073709551615}


So buffer appears to be valid, but duration is not set.

Comment 1 Mark Nauwelaerts 2012-10-26 09:58:34 UTC

Have not been able to reproduce, albeit with other clip(s).  Is this still the case nowadays ?

Comment 2 Tim-Philipp Müller 2012-10-26 10:14:34 UTC

Nope, don't seem to be able to reproduce this any more, though I'm not sure what would've fixed it.
