ffmpeg tee muxer failing with error: Tag avc1 incompatible with output codec id '28'
ffmpeg tee muxer failing with error: Tag avc1 incompatible with output codec id '28'
我可以使用 ffmpeg 将带有 h264 编码视频和 aac 编码音频的 mp4 文件流式传输到 flash flv 输出。我使用的命令是：
ffmpeg -re -i bigbuckbunny_HD_60fps.mp4 -c copy -f flv rtmp://192.168.3.64:1935/main/stream0
当我尝试使用 tee 选项复制输出时，我失败了并出现错误。这是我使用的命令：
ffmpeg -re -i bigbuckbunny_HD_60fps.mp4 -map 0 -c copy -f tee "[f=flv]rtmp://192.168.3.64:1935/main/stream0|[f=flv]rtmp://192.168.3.64:1935/main/stream1"
然而，它失败了。我缺少什么？我从 ffmpeg 得到的输出是：

根据ffmpeg -f tee refuses to do anything useful添加-tag:v 7（或-vtag 7，相同）：

如果出现错误 Tag mp4a incompatible with output codec id '86018' 添加 -tag:a 10 / -atag 10:
