Video 8 capture issues ; Hauppauge, ffmpeg, S-Video and madness
Decyphered the command is:
Issue 1
This setting sets a video codec flag but doesn't fix the output video. Here's an example, sourced from Video8: https://mega.nz/file/eXhi1BQA#1b3kRJ...vHSzmZT7VUP8lQ I can't tell if the capture card is to blame, the S-Video cable, or the program used. I should also note that this same terrible quality output was seen when outputting Betacam tapes. Weird aliasing and forced progressive video... Issue 2
Here's an example, sourced from Betacam: https://mega.nz/file/SWhyVRyQ#ufS1ob...RvkNoay9ojrsIc I should also note that these pops are heard when outputting Video8 tapes. --- I really prefer to use Linux, and this is a headless system. I can get a GUI'd linux machine together but it seems excessive for this. I have no other capture card with S-Video in to test with unfortunately. If really needed yes I will use Windows but I'd prefer not, I do not agree to their EULA. Not sure what the heck is going on here but any help is appreciated. Should I try ffmbc instead? Thanks everybody, glad to be here! :) |
For the first issue, something is causing the fields to be swapped. With e.g swapfields() in avisynth it looks as expected. There is probably some way to do the same with ffmpeg too.
It could be a card setting or driver issue but I don't know. Never experienced that on linux with any capture card, though I have experienced it with a ATI VIVO capture card on a windows XP machine, while other cards on the same machine did not do this. Capturing with ffmpeg should normally work fine. As for audio, I do know that wrong buffer settings can cause popping and similar effects if there are buffer under/overruns. It should be possible to check for that, I think alsa will log it somewhere if it happens. Does the same thing happen with built-in sound card if it has one? Also seeing a fair bit of horizontal wiggling, sending the video through e.g a dvd-recorder like the Panasonic DMR-ES10 / ES15 or other device that can help correct for that. |

My only other test would be in a Windows machine but as mentioned I'm not keen on that... drivers for WIndows 7 are probably hard to come by, and I doubt there's any Windows 10 driver. Also not sure how to capture with ffmpeg as easily as on Linux... The Linux driver is simply the cx23885 firmware for the HVR-1800. https://www.linuxtv.org/wiki/index.p...-1800#Firmware Now this firmware is 10 years old... thus maybe some oversight was made somewhere. The card works fine for all other features but only gives issues with video here. Will have to remove the card my linux system at some point and build a Windows testing machine. Quote:
