Format conversion from yuv420p to NV12 for 720x480 crashes

Description

I want to convert yuv420p file to NV12 format.
It does work for other resolutions, but it crashes for 720x480 resolution.

"ffmpeg.exe -s 720x480 -i input.yuv -pix_fmt nv12 output.yuv"

comment:1 Changed 3 years ago by cehoyos

  • Keywords crash SIGSEGV regression added; ffmpeg yuv nv12 removed
  • Priority changed from normal to important
  • Reproduced by developer set
  • Status changed from new to open
  • Version changed from unspecified to git-master

Regression since a05a44e2 - workaround is to use -cpuflags -sse2
