    johnharew got a reaction from Zando_ in This iPad WILL Change EVERYTHING - Tech Walks Ep2   
    Why are you using a tablet in your car without the screen being in use? To me that seems like a waste of $180. There are many better solutions to use a microSD card in your car that are cheaper. Also, you said that the Galaxy Tab 2 is slow, however my iPad 2 from 2011 still preforms amazing and I have no slowdowns or issues.

    why transfer anything? say the the files where uploaded to the windows server just share that folder, the Linux machine can just process it and move on to the next.

    my answer was as generic as possible.
     
    For example, website could be made out of multiple light servers that only read the transcoded files from a NAS of some sort and stream them to users.
    Such light servers could be dual/quad cores with 4-8 gb of memory, just enough for some light file caching and ability to handle a lot of concurrent downloads ( ex 200 x 3-5 mbps)
    Such servers wouldn't have the processing power to also transcode and it would make sense to copy the big file that needs to be transcoded locally instead of transferring it over the network multiple times.
    For ex. you have a 20 GB 4K file, you transfer it only once to transcoding machine (optionally through a separate 1-10gbps private network),  then maybe extract audio from file to reduce seeking through file and make it easier to encode audio in parallel while video is transcoded... then transcode to 1080p, 720p,360p for video h264 or vp9, opus / aac / mp3 for audio (let ogg vorbis die already) and when all encodes are done mux them in containers if you don't stream them separately like Youtube does with dash.
     
    for low resolution, you could also queue video transcodes in parallel.. for ex with x264 sweetspot for 720p encodings is 10-12 threads, any higher could actually cause tiny loss of quality - so for example if you have a ryzen 8/16 threads you may want to limit 720p transcode to ~10 threads and do the 360p encode in parallel with ~6-8 threads.
     
    pretty much all audio encoders are single threaded, so it's ok to transcode audio in parallel with video as audio will only use 1-2 threads.

    Write a php script that constantly queries a table in a database to see if there are new videos uploaded which have to be converted in various resolutions.
    When new upload is detected, transfer the file to your linux machine (if you don't already host the website on that machine), mark that record in database as "processing"  then run multiple conversions in series or in parallel to create your different formats.
    When you're done, mark your record in the table as done so you won't re-process the file.
    Use Wowza API or whatever to transfer back the newly created files in the right places for wowza to stream them.
     
    Your upload form then only needs to add a record in that database table that's monitored by your script and make the original file available through some means (for example a  ftp server listening on a separate internal network , if you use 2 network cards on your servers)
     
    seems like a no-brainer to me.

    I'd get a 1600 unless you are doing super-heavy streaming or video editing.
     
    Also, get a single 8GB stick, at a faster speed.
     
    use the money you saved on a CPU to maybe go up to a GTX 1070
     
    you also don't need a cooler, since the stock one is pretty good
     
    you could also get a slightly cheaper PSU (M12II) and be fine, although it would be lower quality, so I can't really suggest that without you knowing the full implications of a tier 3 PSU instead of tier 1.

    no point in 212 evo, stock is good enough
     
    Gigabyte non-aorus amd cards suck, get something else, maybe a pulse.
     
    Go for m12ii instead for psu
     
    Use total money saved to get 16gb ram.

    Generated by PCPartPicker 2017-05-16 17:42 EDT-0400   I put in 16GB RAM, and a GTX 1070. although it's slightly over budget. you could save money by going for a cheaper case or cheaper HDD

    check that the hyper 212 you get is compatible unless you want to wait for cooler master to send the new bracket
