| At the line 234 of the file:
| |
| /vizzy/home/iCub/main/src/libraries/icubmod/dragonfly2/linux/FirewireCameraDC1394-DR2_2.cpp
| |
| The <code>dc1394_iso_release_bandwidth(m_pCamera, BANDWIDTH_MAX);</code> function was called, which returned a -3 error.
| |
| After looking for the the function documentation (that can be found [http://libdc1394-22.sourcearchive.com/documentation/2.1.2/iso_8h_9652f00457198f360754eb7087ac3132.html here]), it was understood that the function is no longer supported (as can be seen [http://libdc1394-22.sourcearchive.com/documentation/2.1.2/log_8h_197fe17c786e1f915d99cb19b270e541.html#197fe17c786e1f915d99cb19b270e541 here]).
| |
| To fix the error the code lines 233 and 234 were commented:
| |
| //error=dc1394_iso_release_bandwidth(m_pCamera, BANDWIDTH_MAX);
| |
| //if (manage(error)) { fprintf(stderr,"LINE: %d\n",__LINE__); return false; }
