Question

我正在尝试将用于HLS播放的mp4视频文件分段，我收到以下错误：

＆＃34;无法为输出文件＃0写入标头（编解码器参数不正确？）：未找到Muxer＆＃34;

有谁知道我做错了什么？

输入命令：

sudo ffmpeg -y -i adwd.mp4 -vcodec copy -acodec copy -force_key_frames 30 -map 0  -f segment segment_list adwd.m3u8 -segment_time 10 -segment_format mpeg_ts -segment_list_type m3u8 segment%d.ts

Answer 1

我通过删除强制关键帧解决了这个编码问题（从原始编码中删除命令并设置-flags -global_header参数。

这是我使用的最后一个命令：

sudo ffmpeg -i adwd.mp4 -bsf:v h264_mp4toannexb -c copy -map 0 -flags -global_header  -f segment -segment_time 10 -segment_list adwd.m3u8 -segment_format mpegts adwd%d.ts

Answer 2

出现错误消息表明它无法找到分段多路复用器。您可以使用以下命令检查是否已启用它：

E segment         segment
E stream_segment,ssegment streaming segment muxer

应输出如下内容：


    Router.onStop(function(){
      Session.set("previousLocationPath",this.originalUrl || this.url);
    });

ffmpeg错误：无法为输出文件＃0写入标头（编解码器参数不正确？）：找不到多路复用器
