| tumbleweed | I had forgotten and rediscovered https://github.com/timvideos/HDMI2USB-litex-firmware/issues/465 :P | 17:05 |

| tpb | Title: encoder broken: JPEG file: starts with 0x15 0x0c · Issue #465 · timvideos/HDMI2USB-litex-firmware · GitHub (at github.com) | 17:05 |
| CarlFK | tumbleweed: mithro said something like "maybe there isn't a timing constraint specified, so sometimes it builds ok because the (magic gnomes) route things better." | 17:07 |
| CarlFK | "maybe xobs fixed this by building over and over" | 17:07 |
| tumbleweed | that makes me rather sad | 17:08 |
| CarlFK | I tried that a few days ago, but I was just doing "make image" which may not have been kicking the gnomes into re doing whatever is randomly done | 17:09 |
| tumbleweed | it doesn't seem like a once-off issue | 17:09 |
| tumbleweed | builds from after that point don't have a working encoder | 17:09 |
| CarlFK | yeah - my ignorant guess is more things got added that give the gnomes less room to work with so they cant accidentally make it work any more | 17:10 |
| tumbleweed | sounds legit | 17:10 |
| tumbleweed | I mean, some constraint that isn't specified but was accidentally achieved | 17:11 |
| CarlFK | right | 17:11 |
| CarlFK | Andy or Ben might be able to chase this | 17:11 |
| CarlFK | oh wait, Andy is on site, no time. | 17:12 |
| CarlFK | tell him no beer tonight until he fixes it. | 17:12 |

| CarlFK | "same thing" - with an example image that was valid jpeg, but still broken, which made my automated tests pass and keep me confused for a while, which means icky bug report data durning that time. | 17:16 |
| tumbleweed | yeah, I saw that one | 17:17 |
| tumbleweed | I mean the issue, didn't reproduce it | 17:17 |
| CarlFK | oh, I think if you run the same gst "grab 1 frame" test, 9 times it will error, 1 time it will not error but save a visually broken image | 17:18 |
| CarlFK | but that's based on testing 60ish "make image" results 1x each | 17:19 |
