根因分析

rosbag2的sqlite3存储插件不支持zstd压缩；默认只支持lz4，且未安装zstd的自定义插件。

English

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

解决方案

  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

无效尝试

常见但无效的做法:

  1. 80% 失败

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

  2. 90% 失败

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