Root Cause

The rosbag2 sqlite3 storage plugin does not support zstd compression; only lz4 is supported by default, and custom plugins for zstd are not installed.

中文步骤

  1. 安装rosbag2_compression_zstd插件：sudo apt install ros-humble-rosbag2-compression-zstd
  2. 将包转换为lz4压缩：ros2 bag compress --input /path/to/bag --output /path/to/output --compression-queue-size 1 --compression-mode file --compression-format lz4

Dead Ends

Common approaches that don't work:

  1. 80% fail

    Default sqlite3 plugin code doesn't support zstd; requires a separate plugin package.

  2. 90% fail

    Environment variable alone doesn't install the required plugin; the plugin must be built and loaded.
