| Inky1003 | ezequielg, I've noticed that there is now an horrible V-Sync when converting VHS tapes. Can that be a driver issue?
I was using the stk1160 driver could I send a capture example for what I'm talking about? | [14:20] |
| .... (idle for 15mn) | ||
| milek7 | vsync issue?
I think that's more on video decoder chip rather than stk bridge | [14:37] |
| but I'm curious, does stk1160 driver works for you with standard tools? (ffmpeg, gstreamer, etc.)
I'm getting lots of buffer overflows | [14:44] | |
| *** | camus has joined #linux-media
camus1 has quit IRC (Read error: Connection reset by peer) | [14:45] |
| ezequielg | indeed, vsync is decoder domain (saa7115 driver) | [14:59] |
| Inky1003 | milek7: yes, the driver actually works just fine
I'm just having issues on the video decoding, apparently | [15:00] |
| ezequielg | milek7: can you try a simple gst-launch-1.0 v4l2src device norm ! fakevideosink ?
what norm are you using? Inky1003: have you tried with a clean source? e.g. a DVD, a PAL/NTSC camera, etc? | [15:00] |
| Inky1003 | PAL-M, you mean?
ah sorry, I misread the messages I mean, I've tried with a direct stream of my camera, and It seems to work well Can I send an youtube video showing what I'm talking about? ezequielg (forgot to ping) | [15:00] |
| ezequielg | I really won't be able to help
as I've said, this is not my domain. | [15:03] |
| Inky1003 | Is there anyone who could help me? | [15:03] |
| ezequielg | I don't know the details about the video decoder IC (saa711x) | [15:03] |
| milek7 | gst-launch-1.0 v4l2src device=/dev/video0 norm=NTSC ! fakevideosink
and it spams with buffer overflows kernel 5.12.14 | [15:08] |
| Inky1003 | oh, also ezequielg mine stk1160 driver is spamming ENDSTATUS BEGINSTATUS | [15:13] |

| milek7 | that was broken
but this works fine: https://gist.github.com/Milek7/e6954800517e7635d3c5a8b92f3ce4c4 | [15:21] |
| tzanger | good morning everyone - I'm trying to capture single frames from an rpi camera using v4l2 -- it works, but it seems like many of hte settings do not "stay" -- I'll turn off auto-everything so I can manually control the brightness/gain and the images captured do not appear to reflect the changes
I'm using v4l2-ctl to set things (and read them back) is there an obvious step I'm missing? It seems like v4l2 is trying to save me from myself and I'd like it to let me shoot myself in the foot | [15:21] |

| ...... (idle for 25mn) | ||
| Inky1003 | It's because some capture cards (like the Fushicai USBTV 007) bug the settings. | [21:30] |

| tzanger | Inky1003: well like I said, no capture card here, but I suspect that v4l2 is passing data on to the camera and the camera is saying "lol no" but not reporting any real error | [22:19] |
