looks like the process does not have enough memory to write the frame,
setting a higher value this should work again:

if setting the global value is not an option, it possible to alternatively just use a higher value for video frame extraction.

ogg thumbnails now use oggThumb and seam to work.
WebM thumbs work partially, i.e.:
but the same video with another size works:
are all imagescalers running the same code?
works:

does not work:

Ok, this was due to the imagescalers in production having 8 cores and avconv automatically choosing number of threads based on number of cores. with https://gerrit.wikimedia.org/r/#/c/31244/ this is explicitly set to 1 and memory usage goes down. With just one thread memory usage goes down significantly, it should be possible to change $wgMaxShellMemory again.
