For Prom 30 yesterday evening the 64 bit 31 July nightly build of VLC
reported under its Statistics tab
Lost 0 buffers
Discarded (corrupted) 0
Dropped (discontinued) 0
There was something not quite right because it reported 180094 blocks
Decoded and 90047 buffers Played when they should be the same after
subtracting Lost. It also reported 32 bits per sample when Mediainfo
correctly reported 16. Even so the figures are encouraging.
Since the FLAC stream includes all the R3 output during the trial you can
test whether a recent nightly build of VLC gives you better results than
ffmpeg without risking loss of a Prom. Of course it will not simulate the
extra load during the Prom.
Delay was 2min51s behind FM.
