Never receiving the resend packets has been fixed in fixes/0.25 a
little while ago.
However, finally receiving them only reveal a fundamental flaw in the
current RAOP code ; by the time the retry has been received, the
following packet would have already been played so it end up playing
the audio packet in an incorrect order.
Like you receive:
1, 2, 3, 4, 6, 7 ; 5 is missing it sends a request for 5, so you get the packet:
1, 2, 3, 4, 6, 7, 5 and that's the order it plays ; while there's no
more audio drop like there used to, it creates some weird effects.
As mentioned, I have a full rewrite in progress, and this can't occur,
I also get perfect A/V sync now when playing a video with remote audio
I plan to backport most of it to fixes/0.25 ; and in 0.26 ; you'll get
additional features such as displaying the artwork and name of the
song being played. Well, that's the plan anyway
