根因分析

用于包格式（例如mcap、sqlite3）的rosbag2存储插件未安装，因此无法读取包文件。

English

The rosbag2 storage plugin for the bag format (e.g., mcap, sqlite3) is not installed, so the bag file cannot be read.

解决方案

  1. Install the missing storage plugin using apt.
  2. Check which storage plugins are available and use a supported format.
  3. Re-record the bag with a known working storage plugin.

无效尝试

常见但无效的做法:

  1. Reinstalling rosbag2 package without the storage plugin 70% 失败

    rosbag2 core doesn't include all storage plugins; they must be installed separately.

  2. Converting the bag file manually with a hex editor 90% 失败

    Bag files are structured binary formats; manual editing corrupts them.

  3. Setting ROS_DOMAIN_ID to a different value 20% 失败

    Domain ID affects discovery, not storage plugin loading.
