| CarlFK | jea: xfxf - I have had them flip out and power cycle fixed it. | 00:00 |
|---|---|---|
| jea | turns out it was the frequency. this replacement had 60hz set but camera is 50 | 00:02 |
| jea | as for the original box, it was going bad on the encoder after about 3mins post restart. quite odd | 00:02 |
| xfxf | oh right. yeah all au cameras will be 50 | 00:05 |
| xfxf | herm, we need to flash the firmware on it which is default 50 | 00:06 |
| xfxf | mithro: did you build two firmwares, or just one? | 00:06 |
| jea | mithro just flashed it with the 50hz firmware | 00:06 |
| CarlFK | xfxf: pretty sure "just one" | 00:07 |
| CarlFK | or maybe not. or maybe he made a 50 one... weee!!!! | 00:07 |
| mithro | xfxf: There is a git repo which shows what I did | 00:09 |
| jea | CarlFK: a new 60hz version was made on friday night that we are using for the laptop input | 00:10 |

| mithro | ./mpconfigport.h:80:20: fatal error: alloca.h: No such file or directory | 01:18 |
| jea | I'm using VLC to watch the videos and confirm the times that I want. I was wondering how to properly convert the video time into the time that veyepar wants | 01:19 |
| shenki | mithro: hrm. we don't have an alloca | 01:20 |
| shenki | #include <alloca.h> | 01:20 |
| CarlFK | jea: if vlc says 1:23, put 1:23 in the box. | 01:20 |
| CarlFK | jea: the 'pattern' is h:m:s and if you leave off h or m, then it is just seconds | 01:21 |
| CarlFK | so 61 can either be 61 or 1:1 | 01:21 |
| CarlFK | jea: hopefully you found this: | 01:22 |

| CarlFK | :start-time=051.0 is the vlc syntax for .. start there | 01:23 |
| shenki | mithro: which libc are we using for the lm32? | 01:27 |
| shenki | mithro: can we do a newlib build? that would give us setjmp/longjump | 01:28 |
| mithro | shenki: the above include/base | 01:28 |
| shenki | mithro: or uclibc | 01:28 |
| shenki | mithro: ok. those appear to be copies of glibc headers? | 01:29 |
| mithro | shenki: I think I've fixed the or1k issue | 01:30 |
| mithro | shenki: "export CPU=or1k" - just making the firmware work | 01:32 |
| jea | CarlFK: sorry, had to run to a room | 01:35 |
| jea | Thanks for that info. I'll try it out now. I didn't realise I could just do h:m:s, so that will be much simpler | 01:35 |
| shenki | mithro: are you suggesting i switch back to the ork1? | 01:36 |
| mithro | shenki: yes, I think I am | 01:37 |
| shenki | k | 01:37 |
| mithro | shenki: Hrm, going to ork1 still seems to be missing alloca and setjmp.h ... | 01:39 |
| shenki | mithro: ok. we need to build a toolchain with newlib | 01:39 |
| shenki | mithro: it implements these things | 01:40 |

| shenki | nice | 02:05 |
| mithro | So, ork1 has a crt0 | 02:06 |
| shenki | right .and we normall don't link against it becuase we pass -nostdlib to the linker | 02:06 |

| jea | CarlFK: you around still? | 05:21 |
| CarlFK | jea: yep | 05:21 |
| jea | great | 05:21 |
| jea | we just tried running post_yt.py and hit some syntax issues | 05:21 |
| jea | do you know of anything that has changed in that area? | 05:22 |
| shenki | mithro: can you load this on to a board? | 05:22 |
| jea | CarlFK: the syntax error is in the googleapiclient module, which seems unusual | 05:23 |
| CarlFK | jea: I bet it is a pthon3 thing.. just a sec... | 05:23 |
| jea | yeah, we were thinking that. just surprised that it was an issue in the module | 05:24 |
| CarlFK | if you can find a py3 version, great. but here is my fix (kinda scary, but really nothing is at risk; | 05:25 |
| jea | ah, it looks like an old version of that package. maybe i should just upgrade it | 05:25 |
| CarlFK | cd $(python3 -c "from distutils.sysconfig import get_python_lib; print( get_python_lib())") | 05:26 |
| CarlFK | 2to3 -w steve vidscraper | 05:26 |

| CarlFK | cd.. gets you into the site_packages dir (or dist_packages) | 05:27 |
| CarlFK | 2to3 -w ... ports the code! | 05:27 |
| jea | ok, lets give that a go | 05:27 |
| jea | CarlFK: is there a reason you are using git+https://github.com/CarlFK/google-api-python-client.git#egg=googleapiclient | 05:40 |
| tpb | Title: GitHub - CarlFK/google-api-python-client (at github.com) | 05:40 |
| CarlFK | jea: I think because I tweeked the open().read() to take a file handle instead of a file name | 05:41 |
| CarlFK | but that isn't needed now | 05:41 |
| CarlFK | so that is the reason, but it is no longer a valid reason. | 05:42 |
| jea | ok | 05:42 |
| jea | I | 05:42 |
| jea | I'll switch to the standard one so i have the py3 support | 05:42 |
| CarlFK | cool | 05:43 |
| jea | nearly there. now to work out why google thinks the file is invalid | 05:57 |
| jea | ah, this might be the issue you were mentioning about open | 05:59 |
