JavaCV推流写音频帧报错：org.bytedeco.javacv.FrameRecorder$Exception: avcodec_encode_audio2() error -12: Could

标签：pre code cep 准备 成功 print exception ast pst 我们在设置推流的音频配置时（详细代码参见JavaCV本地视频流通过帧图片添加文本进行字幕合成），指定原拉流时的音频编码器： 我们看输出： 根据日志找到源码： 再跟： 又是一条死胡同。至少我们知道原来的音视频采用的音频编码器是86021，一搜发现 说明这个编码器不行，把设置音频编码器的那一行注释掉或者设置为0，使用默认的编码器就ok了。我指定使用MP3编码器（就是上面的86017）也能成功。 JavaCV推流写音频帧报错：org.bytedeco.javacv.FrameRecorder$Exception: avcodec_encode_audio2() error -12: Could not encode audio packet. 标签：pre code cep 准备 成功 print exception ast pst 原文地址：https://www.cnblogs.com/wuxun1997/p/12937910.html // 音频相关配置，取原音频配置
recorder.setSampleRate(grabber.getSampleRate());
System.out.println(grabber.getAudioCodec());
recorder.setAudioCodec(grabber.getAudioCodec());
86021
准备开始推流...
