  1. Mevo has a Wireless camera that streams using a tablet, there is also a desktop switcher for windows but i wouldn't recommend it unless you need something simple and don't care about audio quality. The cameras are also quite expensive and there's a subscription plan.
  2. It's a personal project that could turn into something more serious. I basically want to write a program where i could read from the database, make changes if needed, run queries and make a tex file with the queried data. Now as far as I know if i decrypt the entire file queries would run faster but then the data would be at risk, right?
  3. Yeah that's what i thought i would have to do but what filetype would the information be saved as before the encryption, just a normal ASCII file with each person having their own line in the file or each person having their own file? I don't think i will need to delete records, just change some information. I probably shouldn't have mentioned encryption since it isn't the problem I'm facing right now.
  4. Hi, I'm thinking about writing a program that would keep records about people, I'd prefer writing it in C and I'd also like to encrypt the database. I would save data like DoB, email, phone number for every person individually and then I'd also have a structure for every "relationship" (Husband, Wife, day of marriage if married and children if any) So my question is, how would I save those records? I've only worked with stuff like fprintf.... So the files werent encrypted. What filetype would i need to use for that? I don't care for any compatibility with other programs and I'd prefer if there wasn't any. Would i need to save the record for every person/relationship in a separate file or would it be better if i have one big file containing all people?
  5. I don't think you need multiplexers. And could you explain what you mean by Universal? Is it Serial and Parallel IN-OUT at the same time?
  6. Hi, So first i should explain the situation I'm in right now. We (A friend of mine and I) have an expensive Livestream subscription and 2 Mevo cameras for a live stream we're doing. The cameras are connected wirelessly to a cheap mobile router/AP combo and then to a iPad and Laptop. Right now we're using Livestream Studio but i would really like to switch to OBS, the Mevo cameras are locked down and can only be used with Livestream Studio (afaik) and i would rather use something else since I often have problems with them. I really appreciate any help you can provide with this since I'd like to make a complete upgrade (PC and Cameras). We would need 2 cameras. I already have 1 FullHD camcorder were using for capturing the stage and showing it on 2 screens on the sides (We're using 2 J-Tech digital HDbitT's to connect wirelessly). I'd like to reuse the camera since we already have a splitter. The camcorder is about 30 meters away from the stage and I'm using optical zoom to zoom in. The problem would be connecting it to the PC since Its about 30-40 meters away. I'd like to avoid wireless since we already have the HDbitT's. I looked into some Optical or Cat6 long distance adapters but I'd like to hear someone else's opinion. The second camera would capture the crowd and could use a normal HDMI cable. Now for the streaming PC. Right now were using a Dell Laptop that's just barely outputing 720p30. I'd like to put a proper PC in a 19" rack. It would need to run Windows and we would probably only use it for the stream (If possible 1080p to Youtube). Now i mentioned that I'd like to stream using OBS and i saw that Elgato now has the ability to use multiple cards (i would use 2 HD60 Pro's , maybe 3 in the future) as sources. As for the audio, i would take it from an existing Phoenix DSP thats in the rack and just use te motherboards Line IN. TL;DR: Got a Livestream subscription, now i need a rig to switch to OBS/Youtube.
  7. Uhh yeah... i never installed Mint so uhmm...did you try restarting it? JK maybe the Iso image had some errors, how about trying another image or an older release? Im not sure if its related to this but did you turn off all the fast/secure boot options in your BIOS? Usually people reccomend turning off fast boot because it messes with some Linux installs, and grub is something that could probably trigger it.
  8. Shrink the C drive to about 50-100gb depending on how much storage you need for linux. You dont need to format it, it can stay unallocated. Boot the linux installation and choose the install linux next to windows or something else (im not entirely sure on the option.) Then you'll be able to choose the partitions. You'll need to make some more linux partitions for root and swap. I usually ask google for the capacity for each.
  9. Not really my story but a friend of mine recently told me he never used a car with a adjustable steering wheel.
  10. Hi. Does anyone have any experience with scraping video descriptions from Livestream.com? I'd like to automate my workflow so i don't have to manually copy all the descriptions to a Google Sheet for each video i upload. Im not asking for any finished code but a few examples how to do it would be great.
  11. I need to do it with livestream studio. It wont be running anything else except chrome and ill use the 2 mevo camers (720p cant get better upload speed), eventually a prerecorded video and a microphone as sources. Thanks. Ill try running a few tests with my laptop before buying since it's a dual core and the minimal requirements according to livestream.com should be a quad core i5 with quicksync.
  12. Does anyone have experience with straming via Livestream studio? I'm looking for a cheap laptop to run the stream. I tried to run it on my Zenbook UX303 (i7 5500U, 8 gb, Geforce 940M) it ran without any problems. While i was testing it the nvidia gpu was on 0% and it was using only the integrated intel... Now i need to find a second laptop to conect 2 mevo cameras and a few audio inputs. My budget is about 400-500$ and the battery life and the build quality don't matter but i would like the laptop to be "futureproof"....i want to use it for at least 3-4 years. Do i need a dedicated graphics card for streaming?
  13. Thanks, I knew about Assembly being different for each architecture (we learned some basics of a custom RISC processor from our college and an ARM), but i guess knowing the basics would help. Would object oriented programming help?
  14. Hi, I'm an electronics engineering student and id like to make some smart home devices, i'd like to know what programming languages I should try to learn. I'm more interested in the hardware side, so i guess C and Assembly would do.... I know some VHDL basics too. I know most companies wouldn't want to share that stuff but does anyone here have some recommendations?
