[FFmpeg-devel] [PATCH] avcodec/on2avc: use the matching AVTX context for the 512 sized iMDCT

[Marton Balint]

Improves the audio corruption regression caused by
6ba0aa1770ba29eb4126c6a706f6b0cd3809648f reported in ticket #10029.

There is still however a noticable audio glitch, so the FFT conversion to AVTX
probably also needs some modifications.
