就是
av_freep(&h->priv_data);这个方法

[lyqaiym]

去年的版本，一直没问题，最近更新了，发现这个问题了

[Android4MediaPlayer]

什么版本？

[lyqaiym]

就是新下载的，失败以后，重新new一个IJKPlayer，就报错了，fault addr deadbaad，但是&h->priv_data的地址还不是deadbaad，

[Android4MediaPlayer]

必现还是跟机型有关

[lyqaiym]

没试其他机型，去年的版本在手机上都没事，
看了方法调用，是不是和多线程有关系啊？

[Android4MediaPlayer]

我上班再看下0.5.0版本

[bbcallen]

I'll take look.

[drawf]

We look forward to fix this bug as soon as possible

[bbcallen]

Did you reproduce this problem in demo, on in your own app?
I can't reproduce here.

1, in the demo, I used to use master translation of the support https armv7a so, this appears to play random error of http or https when hls
2, in the demo, I use compile 'tv.danmaku.ijk.media:ijkplayer-armv7a:0.5.0', http playback of hls, the random error
3, in the demo, I use compile 'tv.danmaku.ijk.media:ijkplayer-armv7a:0.4.5.1', playing the http hls, not wrong

[bbcallen]

How did you "重试" in demo?

[drawf]

They were tested different VideoUri and gradle dependencies

[bbcallen]

I mean "在无网络下播放失败，重试，会出现signal 11"

[drawf]

Sorry, I was wrong always in the presence of network conditions occur

[lyqaiym]

@bbcallen @WANZHI 我好像知道是哪个变量了。是tcp协议的libavformat/tcp.c下的typedef struct TCPContext的AVApplicationContext *app_ctx;我还不知道有啥用，但是我去掉，就没事了
在无网络下，总是走到这个协议的时候，挂了

[bbcallen]

Sounds like you didn't clean and rebuild FFmpeg after a git pull.

[lyqaiym]

@bbcallen 怎么解决啊，不是我一个人有着问题，有时候有网播放hls，释放的时候也会crash

[bbcallen]

No, I still can't reproduce here.

I followed the usage steps on "https://github.com/Bilibili/ijkplayer" and came across the sample issue.

[bbcallen]

Can not reproduce on Nexus 6p, Android 6.0.1.
Do you have any idea about the difference between your test env and my test env?

[lyqaiym]

我用三星s4，必现，在vivo，5.0就没事

[drawf]

0.5.0 is always signal 11 (SIGSEGV) so cut everything back to normal 0.4.5.1

[ielicyan]

My test phone is Huawei Honor-7,Android 4.4.2.
It is OK for local file playback,but crash on m3u8 playback.

[bbcallen]

I'll see if I can get such devices.

[bbcallen]

Possibly fixed in k0.5.1
