把你的~/.fmd/fmd.log贴出来给我看看

lingnand commented 11 years ago

什么叫字符界面下？还有你的连续执行是有没有等到each time the command returns

lapsule commented 11 years ago

就是命令行。这样操作的：

是否考虑加入一个命令缓冲机制，在遇到这种过于频繁的输入的时候过滤掉一些指令，比如如果 2s 内发来多次 skip 指令则只相应最后一条。

在我的机器上没法produce出这个问题。不频繁切换也会这样么？还有你说的等1-2s是否是等那条命令执行完了的（歌确实已经切换了）？

lapsule commented 11 years ago

刚试了一下，即便不短时间内频繁切换，在播放大约10首歌之后再 skip，虽然 fmd 进程还在， 曲目也会改变，但没有声音，查看状态就一直停在 0:00, 虽然显示 "Playing"

lingnand commented 11 years ago

这种情况你只能继续skip，原因是downloader没有速度，所以一直在等速度。有这种问题我怀疑是因为豆瓣的限制，因为我这个版本会同时下载好几首歌，而且会不停下载直至queue empty，所以要是你切的太频繁会在短期内make many connection attempts。你可以尝试修改playlist.h把N_SONG_DOWNLOADERS换成1

Jing.fm底下就没这个问题。

lapsule commented 11 years ago

嗯，可能是 douban 的 API 限制，重新执行一下 fmd-update-conf.sh， 把相应的id之类的更新一下就可以继续播放了

lapsule commented 11 years ago

碰到这种问题能否加一个自动跳过的功能？ 比如在10s之后 downloader 还是没有回来就自动 skip？

lingnand commented 11 years ago

可以是可以。我可以在downloader里面加限制，比方过多久没速度就跳过；但是这种东西很难说，可能真的网络不太好，user would want to choose to wait for it to recover。所以暂时不会加这种功能。

lingnand commented 11 years ago

豆瓣这种问题比较严重是因为每次skip都会tell Douban you skipped this particular song and fetch new playlist，每个playlist有五六首歌的样子；如果你的网速够快，这意味着如果半分钟你跳3～4首歌可能会下载十几首歌。我也想过这个问题，比如skip的时候不重新fetch playlist，但是终究没有去多研究因为平常不常碰到这个问题。

如果you are particularly troubled by this problem, you can try out the channel '#psn' if you have a Jing.fm account, which does not trigger new playlist fetch on skipping (and generally provides better music quality as well)
