android - Capturing audio frames from HDMI IN port -

-

I have a root HiSense GoogleTV that has HDMI in and out ports.

What I have to do is record 10 seconds of audio from HDMI (from set-top box) I'm new to it, so please stand with me.

  1. Is it possible to do this on a routed device?

  3. If I get decrypted in HDMI and after HDMI before I'm out via HDMI ( Due to HDCP) and is encrypted again? Regularly the audio frame on the Linux box, how should I go about it? Which component should I see? I can not get a document that describes low level architecture and details of how HDMI can deliver these signals to HDMI Out.

  4. Can you really point to the Android Framework Code, Is this routing out of getting HDMI? Basically, during the exit of HDMI, I want to understand the flow of what is happening with the audio signal.

    I'm not sure that my questions mean, but I hope you can give me some pointers where I should start.

    short answer: is not possible. The pass-through is completely different from Android through reliable video path SOCS. You must be a Certified Society provider to get anywhere near the signal.

I do not think this is a relativant code. Can anyone tell me what should I do? I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel). Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.

github - Teamcity & Git - PR merge builds - anyway to get HEAD commit hash? -

-
I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee. The annoying thing is that you can not do anything useful with the merged hash - it is not present in Gitobb. I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge. (PR - Pull Request) This command works reliably while running One on / merge is git log --no-merge -1 ---- = '% h'
