[Bug 974572] Re: Some PNG Frames Render Black or With Checksum Errors

 

I can't reproduce this on 1.4.2. What versions of libavformat,
libavcodec & MLT do you have?

There are no code changes between 1.4.0 & 1.4.2 that I can think of that
would affect this. In fact, there is very little code in OpenShot at all
that influences the rendering, as that is all handled by MLT/FFMpeg.

Title:
  Some PNG Frames Render Black or With Checksum Errors

Status in OpenShot Video Editor:
  New

Bug description:
  I am running Openshot 1.4.2 in Mint Linux, which is running inside of
  VirtualBox.  I am exporting the video as individual frames to be
  compressed elsewhere.  Some PNG frames render black or with checksum
  errors.  This behavior isn't consistent.  Sometimes all of the frames
  appear to render properly, yet they still have checksum errors.  There
  were black frames in Openshot 1.4.0, but there appear to be less in
  1.4.2.  As a work-around, I am able to use Irfanview to remove the
  checksum errors from each of the PNG files.

  Notes:
  I installed the 1.4.2 .deb version

  I render to the PNG frames because the videos I was previously
  creating from OpenShot also had the black/skipped frames.
