针对您遇到的错误 "could not find tag for codec pcm_s16le in stream #1, codec not currently sup",这个问题通常出现在使用FFmpeg或其他音视频处理工具时,特别是在处理包含多个流(如视频、音频等)的媒体文件时。下面我将按照您提供的tips逐一解答: 1. 确认问题背景与上下文 您可能正在使用FFmpeg等工具尝试对包...
如果您遇到了pcm_s16le codec not supported的错误,可能是因为FFmpeg没有安装支持该编码器的库。您可以尝试使用以下命令查看FFmpeg已安装的音频编码器: ffmpeg-codecs|grep PCM 如果输出中不包含pcm_s16le编码器,则需要重新编译FFmpeg并启用该编码器。 如果您已经确认FFmpeg已经安装了pcm_s16le编码器,但仍然出现了上述错...
只要交换每个sample的高8bit和低8bit就可以了
