[FFmpeg-user] Repeatable output?
When can I expect the output of ffmpeg to be byte-for-byte identical across runs given the same input and command-line flags? When I do simple tests now I always see the same checksums, but I remember (sorry, short on details) often seeing different results with the same commands in the past. Thanks!

By default scale is auto scaled to sum of weights. Correct would be "By default scale is set to (1 / sum_of weights)". The same error is also in the documentation of the "tmix" filter. Is there one scale for all inputs or one scale per input? One for all inputs. Criticism (re, "Specify weight"): "If number of weights is smaller than number of frames" -- Huh? "number of inputs" The same error is also in the documentation of the "tmix" filter.
