| whitequark | DocScrutinizer: do you mean that they essentially have two copies of Linux running, one on BP and one on AP? | 00:11 |
|---|---|---|
| DocScrutinizer51 | there's no AP | 00:16 |
| DocScrutinizer51 | and BB runs OSE | 00:16 |
| whitequark | DocScrutinizer51: this one? http://en.wikipedia.org/wiki/Operating_System_Embedded | 00:51 |
| wolfspraul | just wondering about a good lossless compression format for video | 05:34 |
| wolfspraul | for music it seems to be FLAC, but for videos? | 05:34 |
| wolfspraul | free one of course, who would want anything else? :-) | 05:35 |
| wolfspraul | http://en.wikipedia.org/wiki/List_of_codecs#Lossless_compression | 05:35 |
| wolfspraul | "ask google" has become "ask wikipedia" | 05:35 |
| xiangfu | file "Movie_00_(111102)_Naihanli_Crates.m2t" | 05:38 |
| xiangfu | Movie_00_(111102)_Naihanli_Crates.m2t: MPEG transport stream data | 05:38 |
| DocScrutinizer | whitequark: http://de.wikipedia.org/wiki/Enea_AB | 05:38 |
| wolfspraul | seems the ffmpeg FFV1 is a good candidate | 05:41 |
| DocScrutinizer | whitequark: sp yes, enea OSE | 05:42 |
| DocScrutinizer | so* | 05:42 |
| wolfspraul | lossless movie compression, free encoder and decoder, developed as part of the ffmpeg project | 05:42 |
| wolfspraul | still trying to find out how active this is. there is another one 'snow codec' but supposedly stalled? | 05:42 |
| wolfspraul | we should ask David - dvdk where are you? :-) | 05:43 |
| wolfspraul | (sometimes he magically comes into the channel when his name is called :-)) | 05:43 |
| DocScrutinizer | http://www.enea.com/ose | 05:44 |
| wolfspraul | lossless motion jpeg 2000, another option... | 05:45 |
| wolfspraul | lossless dirac | 05:46 |
| DocScrutinizer | moo wolfspraul | 05:49 |
| wolfspraul | hey :-) | 05:54 |
| wolfspraul | http://ffmpeg-users.933282.n4.nabble.com/up-to-date-lossless-codec-comparison-td3175359.html | 05:55 |
| wolfspraul | need to study this some more | 05:55 |
| wolfspraul | ffv1, dirac lossless, yuv, dpx (?) | 05:56 |
| wpwrak | just a sequence of PNG ? ;-) | 06:04 |
| wpwrak | simple but brutal :) | 06:04 |
| whitequark | DocScrutinizer: ah, so are you working at ENEA? | 07:11 |
| DocScrutinizer51 | ericsson | 07:17 |
| mth | my favorite lossless video codec is ZMBV, but that's rather specific in the kind of video it is good at (retro games, basically) | 07:57 |
| mth | it does get a good compression ratio if the source material is right | 07:58 |
| mth | and Youtube accepts it as an upload format | 07:58 |
| mth | it might actually perform quite well with screencasts too, as long as you don't use any fancy 3D animation effects | 08:00 |
| kristianpaul | cheers mirko !! | 11:29 |
| Artyom | hi kristianpaul | 20:20 |
| kristianpaul | Artyom: hello | 20:30 |
| Artyom | How is your work with namuru? | 20:30 |
| kristianpaul | i'm debugging the issue (ignorance) i still having printing signed numbers | 20:31 |
| kristianpaul | i just noticed your arm soc uses 16 bits bus :) | 20:31 |
| kristianpaul | i my case i'll set all wired to 32 bits. working on it right now | 20:32 |
| kristianpaul | and make sure the sign i put is compatible with lm32 | 20:32 |
| kristianpaul | arch manual said is two complement i think | 20:32 |
| Artyom | yeah, 16-bit is board limitation... | 20:33 |
| kristianpaul | also i think i'll merge your osgps mode to the demo code | 20:34 |
| kristianpaul | s/mode/mo | 20:34 |
| kristianpaul | s/mode/mod | 20:34 |
| kristianpaul | thats all so far, how about your milkymist porting? | 20:35 |
| Artyom | well, I found working port for digilent spartan3e board. It boots bios from flash and permits to upload programs through ethernet | 20:36 |
| Artyom | I also could connect external clock from front-end | 20:37 |
| kristianpaul | ah,soc is using single clock now, nice ! | 20:37 |
| Artyom | now I study wishbone and next step is to connect correlator through this bus | 20:38 |
| Artyom | And also debugging becomes very important. So I have to learn how to debug | 20:39 |
| kristianpaul | i asked to mwalle #milkmist, he point gdb is working | 20:40 |
| kristianpaul | hw debuggin still now quite friendly, but wpwrak had step into a better way to tap wires than just writing in verilog | 20:41 |
| kristianpaul | Artyom: or you also mean debug namuru it self? | 20:42 |
| Artyom | I mean debugging with gdb | 20:42 |
| Artyom | I had experience with gdb only from eclipse | 20:43 |
| kristianpaul | i have zero | 20:43 |
| kristianpaul | well i think once i copy and paste something that allow me to run a code step by step, not sure if this was gdb... | 20:44 |
| kristianpaul | need recall too :| | 20:44 |
