测试录音然后播放opus文件发现声音急促

1

非常感谢你写的这个demo，能够将pcm流编码为opus文件输出。目前测试中发现录音后播放文件听到声音比较急促，像是录制的声音间隔太长被截取导致。从日志中发现录制间隔较长，试着把录制的buffer调整为较小的320，然后每次直接全部wirteFrame，发现编码出来的声音不正常。目前没有十分了解opusaudio.c中实现int writeFrame(uint8_t *framePcmBytes, unsigned int frameByteCount) 的逻辑。实现中每次写入buffer编码后都调整文件头是否必须，能否在终止录音时再补充（不考虑中间异常退出情况）? 另外，实现中感觉像是每次写入是重采样，是否是需要的。 为何调整写入的buffer大小会造成编码出来的声音不正常？（demo中默认时1920）

Hi作者你好感谢你提供这么好用的库 我现在发现一个问题，使用demo录制opus文件，然后decode成wav，再将wav文件encode成opus [round 1] recoder opus [round 2]decode opus to wav [round 3]encode wav(the same round 2) to opus 发现round3 的opus文件会比 round1 的opus文件大一倍,具体是哪些参数影响呢？
