But other changes may be needed too. This is being actively looked at. General hint about GDB (though I think at this point we probably don't need more): if you type "bt" at that point hopefully it will give you a list of other functions that were called prior to the one which is immediately printed (ff_imdct_half_avx.pre in this case), which can sometimes be helpful. And in the case where there are entries coming from libraries (like libavcodec in this case), installing the debug-package for the library can be helpful too (this one is from ffmpeg, and there's a "debug-ffmpeg" package). > This is the core after trying to play a video file encoded with vp9: > > $ egdb mpv mpv.core > > .. > #0 0x0000099a1ac9ff51 in ff_fft_calc_sse () from > /usr/local/lib/libavcodec.so.25.0 > [Current thread is 1 (process 308636)] I think this one in particular (fft) is very likely to be fixed by the ffmpeg commit.
