On my laptop (i5-8365U), running cross-tesseract-ocr in QEMU takes longer than the default timeout (5s), causing the test to fail: # time tesseract frame10.png output Error in pixReadMemTiff: function not present Error in pixReadMem: tiff: no pix returned Error in pixaGenerateFontFromString: pix not made Error in bmfCreate: font pixa not made Estimating resolution as 157 real 0m 8.17s user 0m 5.36s sys 0m 2.79s So extend the assertRunOk() timeout with ~2x that similar to how it is done for the gst-launch-1.0 pipeline.
