Hi All,

Since a week I have piCorePlayer running on a Raspberry Pi ZeroW, and am
very pleased with it. I encountered a few issues however with native
playback of WMA files (to be specific: WMA Lossless and WMA Pro files)
that I want to report here.

For native playback of ALAC and WMA files I installed the "FFMpeg
libraries for Squeezelite" via the pCP web interface (pCP Main Page).
After installation of the FFMpeg libs I performed some playback tests.
For these tests I created WMA files with different WMA formats using
Windows Media Player 12.

The test results do not meet my expectations. Summary of the test
results:
1) Native playback of ALAC and "normal" WMA files works fine. So far so
good!
2) Native playback of the WMA Lossless file does not work. For some
reason WMA Lossless is transcoded to 705 kbps FLAC by LMS. If I disable
transcoding for WMA Lossless in LMS, pCP does not play the WMA Lossless
file.
3) Native playback of the WMA Pro file starts OK, but after some time
playback stops. It seems that squeezelite has crashed. After playback
has stopped I cannot play any audio file anymore with pCP. A pCP reboot
is required to get pCP working again (when disabling native WMA Pro
playback in LMS, LMS correctly transcodes the WMA Pro File to FLAC, and
then playback works fine).


************************************************************************
DETAILED INFORMATION BELOW
************************************************************************

Software versions used are as follows:

PLAYER:
piCorePlayer 6.1.0
piCore v10.3pCP
Squeezelite v1.9.7-1256-pCP
FFMpeg libraries that come with pCP 6.1.0

SERVER:
LMS 7.9.3 - 1591161343 @ Thu Jun 4 04:07:50 WEDT 2020, running on a
Windows 7 64-bit system.
Also tested with LMS running on Lubuntu 18.04 64-bit. LMS Linux does not
do transcoding from WMA to a different audio format, meaning that only
"normal" WMA files can be played back on my pCP player when running LMS
on a Linux system.

For completeness here are links to the WMA test files that I used for my
playback tests. Each file is the same music track with length of 1:32 (1
min 32 secs).
1) The normal WMA 9.2 file that is played back fine by pCP can be
downloade here => 'Prelude WMA.wma'
(https://www.dropbox.com/s/gmp3sl6g2yxlcay/Prelude%20WMA.wma?dl=0)
2) The WMA 9.2 Lossless file that is not natively played back by PCP can
be downloaded here => 'Prelude WMA Lossless.wma'
(https://www.dropbox.com/s/gxuwngwi615bva6/Prelude%20WMA%20Lossless.wma?dl=0)
3) The WMA 10 Pro file that makes pCP/Squeezelite crash can be
downloaded here => 'Prelude WMA Pro.wma'
(https://www.dropbox.com/s/qznf7hgjgqzvzd0/Prelude%20WMA%20Pro.wma?dl=0).
When natively playing back this file, my pCP 6.1.0 player always crashes
at 1:18.

************************************************************************

Does anybody have an idea why my pCP 6.1.0 player does not play back my
WMA Lossless file natively? And more important, why pCP crashes when
natively playing the WMA Pro file?
I can provide more information on request.
