Hi all,
I'm using the **prosilica_driver node** to access images from my camera (AVT Manta G235B) in **ROS indigo** running under **Ubuntu 14.04**.
The problem I'm experiencing is twofold
- First, a **lower framerate** (about **10 Hz**
according to rostopic hz) than the
expected one (**50 Hz** from datasheet
and about 50 Hz tested on Windows
with the camera provider software).
- Second, **Rosbag** (via rqt_bag) is
complaining like that when I try to **log the camera frame**
[INFO] [WallTime: 1411548138.205121] Recording to /home/ragingbit/test_2014-09-24-10-42-18.bag.
Traceback (most recent call last):

TypeError: BagTimeline.selected_region_changed[Time, Time].emit(): argument 1 has unexpected type 'NoneType'
Any help is really appreciated! :)
