[FFmpeg-devel] ffmpeg crash with out of memory error (perspective filter?)

[Joshua Grauman]

Hello all,

Unless I'm missing something, I think I must have found a memory leak in 
ffmpeg (probably the perspective filter?). The following command runs fine 
(ie. produces good output), but if I run it for too long (~6000+ frames), 
eventually the frame rate starts to drop and finally the process gets 
killed with an out of memory error. Anyone want to help me debug it? 
Here's my ffmpeg version info too (which I compiled from the main git 
source). Thanks!

Josh
