bash - FFmpeg:管段到 s3

Question

我想将 ffmpeg 段通过管道传输到 s3 而不将它们写入磁盘。

ffmpeg -i t2.mp4 -map 0 -c copy -f segment -segment_time 20 output_%04d.mkv

是否可以修改此命令，以便 ffmpeg 将段写入 s3 存储桶？大概是这样的？

ffmpeg -i t2.mp4 -map 0 -c copy -f segment -segment_time 20 pipe:1 \
  | aws s3 cp - s3://bucket/output_%04d.mkv

当我运行上面的命令时，我收到此错误

Could not write header for output file #0
(incorrect codec parameters ?): Muxer not found

此命令有效，除了上传整个视频而不是单个片段

ffmpeg -i t2.mp4 -map 0 -c copy -f segment -segment_time 20 pipe:output_%04d.mkv \
| aws s3 cp - s3://bucket/test.mkv

它适用于 s3fs。在 Ubuntu 18.04.4 LTS 上测试。
s3fs 版本:

从源代码编译；永远无法让它与从“apt install s3fs”安装的常规版本一起使用。您需要正确配置 .aws/credentials 然后挂载一个文件夹:

root@ip-172-31-69-62:~# s3fs sm-alfa-beta /mnt/s5

不要管它；将其视为常规文件夹，它位于 S3 存储桶上。

在 Ubuntu 18.04.4 上编译 s3fs 的说明:

sudo apt-get install build-essential libcurl4-openssl-dev libxml2-dev pkg-config libssl-dev libfuse-dev automake

cd /tmp && \
git clone https://github.com/s3fs-fuse/s3fs-fuse.git && \
cd s3fs-fuse && \
./autogen.sh && \
./configure  && \
make

sudo make install
