Ijkplayer: 使用「ijkio:cache:ffio:」缓存音频的话64位会报错

Created on 12 Jun 2019 · 12Comments · Source: bilibili/ijkplayer

有人知道解决办法吗？如果使用32位的library就没有问题

libijkffmpeg.so (av_opt_next+24)

我也遇到了相同的问题，不过我已经解决了，在libavutil/opt.c文件的av_opt_set_defaults2函数中加入
if (opt->offset == 0) continue;
你也可以直接使用我编译好的

only one symbol av_opt_next in the backtrace ?

befovy on 13 Jun 2019

是的，而且是必现的问题。你有什么思路之类的吗

lrannn on 14 Jun 2019

I have not used ijkio:cache:ffio in the past time.
@lrannn
if you can provide the way to reproduce this crash, I will try it when I have free time

不好意思我刚看到回复。测试代码如下：

        mediaPlayer = new IjkMediaPlayer();
        mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
        mediaPlayer.setDataSource("ijkio:cache:ffio:real_audio_play_uri");
        setupIjkPlayerOptions(mediaPlayer);
        mediaPlayer.setOnPreparedListener(this);

        mediaPlayer.prepareAsync();

    //设置Cache相关的参数
    private void setupIjkPlayerOptions(IjkMediaPlayer mIjkPlayer) {
        String basicPath = Environment.getExternalStorageDirectory().getPath() + "/tt/tmp/";
        mIjkPlayer.setOption(IjkMediaPlayer.OPT_CATEGORY_FORMAT, "cache_file_path", basicPath + "audio.tmp");
        mIjkPlayer.setOption(IjkMediaPlayer.OPT_CATEGORY_FORMAT, "cache_map_path", basicPath + "2.tmp");
        mIjkPlayer.setOption(IjkMediaPlayer.OPT_CATEGORY_FORMAT, "parse_cache_map", 1);
        mIjkPlayer.setOption(IjkMediaPlayer.OPT_CATEGORY_FORMAT, "auto_save_map", 1);
    }

这段代码在armv7下是正常的，功能也可以使用，如果使用arm64-v8a的包，则会crash。目前我的解决办法为只使用armv7的so库。

Hi @lrannn , sorry for the late.
I add native c code debug ability for ijkplayer, you can get the update from https://github.com/befovy/ijkplayer.

I tried the step you said, but no crash.

By using https://github.com/befovy/ijkplayer for native bug, you can see which line lead to the crash if it crashed in the ijkplayer's c source code.
Hope the solution from you.
BTW, I use ndk version r15c.
