The seek table in a Xing/Info header is very imprecise (max resolution of 255 to describe each of 100 byte positions in the file). Seeking using a constant bitrate assumption is more accurate, especially for longer files (which exacerbates the imprecision of the Info header). VBR files should contain an Xing header, while an Info header is identical but indicates the file is CBR. Issue: androidx/media#878 PiperOrigin-RevId: 597827891
