[FFmpeg-devel] [PATCH] fate: Add test for Musepack SV8 decoding

Fri Oct 30 14:58:09 EET 2020
While the FATE suite contains a sample file for Musepack 8, it did not
use it to test the decoder; it is only used in the mpc8-demux test that
tests the demuxer via streamcopy. Therefore this commit adds an actual
encoder test.
The test uses the framecrc output, because Musepack SV8 is an encoder
that returns multiple frames for a single packet, so that timing
information in the test output is valueable. Output seeking has been
used in order to limit the size of the ref file as well as to test this
codepath for the first time.

For some reason sometimes the timestamps are off by 1; i.e. the
timestamps of the packets with timestamps in the range 28151-71927 are
all one too small. But the error does not accumulate.
