根因分析

rosbag2存储插件（如sqlite3）不支持指定的压缩格式（如lz4、zstd）。支持的格式取决于插件版本和构建选项。

English

The rosbag2 storage plugin (e.g., sqlite3) does not support the specified compression format (e.g., lz4, zstd). Supported formats depend on the plugin version and build options.

解决方案

  1. Check supported compression formats: ros2 bag info /path/to/bag. If unsupported, re-record the bag without compression: ros2 bag record -o my_bag --no-compression /topic1 /topic2. Then play back: ros2 bag play my_bag
  2. If you need compression, use a supported format like 'zstd'. Record with: ros2 bag record -o my_bag --compression-mode file --compression-format zstd /topic1. Ensure zstd is installed: sudo apt-get install libzstd-dev
  3. For custom builds, rebuild rosbag2 with the desired compression plugin: colcon build --packages-select rosbag2_compression --cmake-args -DCOMPRESSION_LZ4=ON. Then restart recording.

无效尝试

常见但无效的做法:

  1. 90% 失败

    The system library is not enough; rosbag2 must be built with lz4 support enabled at compile time. Simply having the library doesn't enable the plugin.

  2. 85% 失败

    Changing the environment variable only affects recording, not playback. If the bag was recorded with lz4, playback will still fail if lz4 is unsupported.
