Canplayer won't replay candump files
It seems I had recorded the log files in a wrong manner.
My logs files where recording using the following command:
$ candump -ta vcan0 "log.candump"
That command, however, records the log in human readable format:
vcan0 1B3 [8] 8E 02 74 22 55 70 49 30
vcan0 658 [6] 27 48 2C 56 14 0A
vcan0 1F8 [2] 77 99
vcan0 7B7 [8] 33 A2 24 38 B2 78 86 72
vcan0 43C [8] 92 C6 81 2E FC 5E 38 35
vcan0 7B0 [2] 2D 1B
In order to record log files that can be playback with canplayer, they should be recorded using either
$ candump -l vcan0
or
$ candump -L vcan0 > myfile.log
The recorded file will look like this:
(1436509052.249713) vcan0 044#2A366C2BBA
(1436509052.449847) vcan0 0F6#7ADFE07BD2
(1436509052.650004) vcan0 236#C3406B09F4C88036
(1436509052.850131) vcan0 6F1#98508676A32734
(1436509053.050284) vcan0 17F#C7
(1436509053.250417) vcan0 25B#6EAAC56C77D15E27
(1436509053.450557) vcan0 56E#46F02E79A2B28C7C
(1436509053.650713) vcan0 19E#6FE1CB7DE2218456
(1436509053.850870) vcan0 1A0#9C20407F96EA167B
(1436509054.051025) vcan0 6DE#68FF147114D1
Files in that format can be replayed in canplayer using the following commands:
$ canplayer -I candump-2015-07-10_081824.log
or
$ cat candump-2015-07-10_081824.log | canplayer
