MP 0.26 Linux: Quicktime thumbnail depends on timescale

Post by mike1158 »

Hi. Longtime xnview user, first time checking out xnviewMP. Looks awesome so far!

I pointed it at my animation reference library, and came across a really strange bug. Some quicktimes show a thumbnail, and some don't. It isn't permissions, isn't related to file size, and isn't the codec (all are mjpa). I think it's actually the time scale!

For example, these all show a thumbnail just fine (all 2997 time scale):
cat_fastwalk_side_01.mov rate 599.400024 [2997:5] not constant
cat_walk_34back_01.mov rate 49.950001 [2997:60] not constant
cat_walk_34back_02.mov rate 71.357140 [2997:42] not constant
cat_walk_side_lickbutt.mov rate 29.969999 [2997:100] constant

but none of these do (all NOT 2997 time scale):
cat_FastWalk.mov rate 24.000000 [600:25] constant
cat_SideStepping.mov rate 24.000000 [600:25] constant
catSlowMo_Walk_A.mov rate 85.714287 [600:7] not constant
catSlowMo_WalkBackAndForthToSit.mov rate 46.153847 [600:13] not constant
catSlowMo_WalkFromSit_A.mov rate 35.294117 [600:17] not constant
catSlowMo_WalkFromSit_B.mov rate 29.970030 [30000:1001] constant
catSlowMo_WalkTurnAround.mov rate 75.000000 [600:8] not constant
cat_WalkHeadOn_slomo.mov rate 24.000000 [600:25] constant
cat_WalkProfile.mov rate 24.000000 [600:25] constant

Let me know if you need sample files for testing.
