4:2:2 again. Maybe, probably.

Just wondering if there is a way to run VLC on a receiver and have 4:2:2 display with it as opposed to the round about webif method or if there is a way to watch those channels in a more direct fashion.
On a side note when tuning to one of these channels on a receiver (mine's an OsMio 4k) does anyone experience it freaking out and locking up requiring a cold boot?
I can watch them in VLC but after a few minutes the picture freezes and going back to the receiver HDMI port on my smart tv, it's all green and frozen too.
Anyone?
 
The video in the fta receiver does not allow 4:2:2 codec. So it is doubtful you will not get a 4:2:2 picture using anything inside the receiver including VLC. Broadcom considers 4:2:2 to be a professional codec, and this is why it is not included in fta receivers. Some receivers such as AzBox Premium+ were able to receive 4:2:2 content years ago, but this company suddenly went out of business, and the unauthorized 4:2:2 was probably part of the reason.

The locking up and freezing is a genuine problem in the MIO line of receivers. This problem exists for me only when more than one 4:2:2 channel has been selected back to back. If you look at each channel in the 4:2:2 mux, then the receiver may freeze and require a reboot. The solution or work-around is to select a 4:2:2 channel, and then a regular channel. Alternate between 4:2:2 and regular channels. My guess is the MIO gets clobbered with garbage from trying to decode 4:2:2 content, and this could explain Why the receiver locks up when several 4:2:2 channels have been viewed back to back or in a row. You may ask whoever you bought the receiver from about getting this fixed.

I have not experienced any freezing when streaming 4:2:2 channels. But if channels were being changed to other 4:2:2 channels during streaming, then the whole thing could lock up.
 
Something else crossed my feeble mind awhile ago. If the receiver just cannot display 4:2:2 because of hardware limitations or if that portion of the processor isn't switched on.
VLC from reading can do software decoding also. It apparently uses a lot of processor power to do it, but I guess it can. I understand that an Nvidia can do things that an AMD GPU cannot solely because of Nvidia CUDA. And do it at a blazing speed.
Anyway. Since VLC cannot decode 4:2:2 in the Mio because of the Broadcom chip, would software decoding even be feasible? I have a difficult time understanding terms like software decoding and if it relates to anything like if it streams the video to a piece of software and produces video and bypasses the video decoding module all together. But does pass the processed video to the video display.
 
We have had VLC plugins for enigma2 before, and they would not work on the 4:2:2 channels. The only way to receive 4:2:2 is to send the content out and decode it. This means watching 4:2:2 on a computer, OR sending the 4:2:2 channel through the computer and back to the receiver (stream relay).

using different methods to receive 4:2:2 in enigma2 receivers have been tried for years. A solution that works inside the fta receiver has not been found, but that does not mean a solution does not exist!

Let us know if you find something that works...
 
No solutions yet but always ideas. I have an HDHomerun OTA/Cable receiver that sends channels by TCP/IP. Pretty slick.
Not entirely sure how the webif works to be able to load or simply click the little TV box and have VLC popup on my PC or Android tablet.
All I do know is that it does work.
It would be nice though to have a quick way to launch VLC on my smart TV, Fire Cube and see a channel list I could watch these 4:2:2 channels on.
Stream Relay. That's the term I was thinking of. Capture a channel and do the processing <wherever> and send it to a valid device capable of displaying it. I don't know. Time to pull out the geek boots again. Thanks, El.
