Root Cause

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.

Workarounds

  1. 90% success 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. 85% success 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 
    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. 75% success For custom builds, rebuild rosbag2 with the desired compression plugin: colcon build --packages-select rosbag2_compression --cmake-args -DCOMPRESSION_LZ4=ON. Then restart recording.

中文步骤

  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.

Dead Ends

Common approaches that don't work:

  1. 90% fail

    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% fail

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