【求助】【TuyaOS SDK】【T32_uclibc_r337_TuyaOS-3.10.16】保存为mp4的要求
视频使用的是H265，音频使用的是PCM，在APP端可以实现预览。
但保存的视频文件无法回看，拿到电脑端播放帧率很快，15000的帧率。
查资料，mp4是不支持pcm的，所以音频编码那里有问题吗？需要音频改为ACC格式吗，ACC有三种具体是哪一种呢？附件为出问题的mp4文件（需要解压，附件不支持上传mp4）

参照开发者文档： https://developer.tuya.com/cn/docs/iot- ... 4%EF%BC%9F

提供debug 日志

参照开发者文档的结果，日志文件有点大。
附件有日志文件和代码部分。打印的帧信息与ringbuf里面的一样。
下面是日志部分，自行增加打印的时间戳与debug调试的打印一样。

1. 从日志中很多音频帧的时间戳相同，音视频帧理论上应按照设置的帧率写入ringbuf, 否则会影响 mp4 文件的转码

   Code: Select all

   [09-10 20:17:30 ty T][9174][tuya_ring_buffer.c:990] append done, ch0st0tr9 node index:3 timestamp:1757506650631
    [09-10 20:17:30 ty T][9174][tuya_ring_buffer.c:990] append done, ch0st0tr9 node index:4 timestamp:1757506650631
   [09-10 20:17:30 ty T][9174][tuya_ring_buffer.c:990] append done, ch0st0tr9 node index:5 timestamp:1757506650631
   

2. 增加的打印可集中在一行输出，查看日志可以更直观。
