Dear libav users, I am working on a visual tracker that uses motion vectors extracted from H.264 and MPEG4 encoded videos. So far, I only observed values +1 and -1 for the "source" field of AVMotionVector struct: https://www.ffmpeg.org/doxygen/4.1/structAVMotionVector.html#a0cb88b0996a7313be9f91b92b82819b7
Now, I am wondering whether the source value can have an absolute value larger than 1. The documentation is a bit ambiguous as it contains the note: 'XXX: set exact relative ref frame reference instead of a +/- 1 "direction"'. Looks like a Todo to me which would imply that currently only values +1/-1 are used. Any ideas on how I can force the encoder to produce some vectors with absolute source values larger than 1? I want to test my algorithm to ensure it won't brake once it encounters different source values. Thanks a lot!
