You can do that with the concat demuxer:
file a.jpg
duration 5
file b.jpg
duration 3
Note that the last frame's duration may not be preserved by the rest of the
chain, especially if you use -vf fps=X:round=down to achieve a common frame
rate. You can work around that using a final last frame:
file b.jpg
duration 2.96
file b.jpg
duration 0.04
