Maximum JPEG image size may be reached #23

Open sbrodeur opened 7 years ago

The current maximum number of bytes for a JPEG-encoded image is 32768 when exporting a rosbag to HDF5: https://github.com/sbrodeur/ros-icreate-bbb/blob/master/src/action/scripts/record/data/convert_hdf5.py#L124

This led to errors lately because some images were going over this limit. The script could be adapted to automatically increase the shape of the data, similarly to what is done here for the time dimension: https://github.com/sbrodeur/ros-icreate-bbb/blob/master/src/action/scripts/record/data/h5utils.py#L111

Right now, we just use a bigger value of 40000.
