google cloud platform - How to fix av_interleaved_write_frame() broken pipe error in php

I have an issue using ffmpeg to stream audio and parse to google cloud speech to text in PHP.

It returns this output. I have tried delaying some part of the script, that did not solve it. I have also checked for similar questions. however, they are mostly in python and none of the solutions actually work for this.

I'm not sure what the issue is at this time.

UPDATE

I've done some more debugging and i have gotten the error to clear and to stream actually starts. However, I expect the audio to transcribe and update my database but instead I get this error when i close the stream

this is my updated code

    $handle = popen($ffmpegCommand, "r");

    try {

What prevents you from obtaining the diagnostics? From what I see those are **av_interleaved_write_frame(): Broken pipe** 256.0kbits/s speed=1.02x **Error writing trailer of pipe:: Broken pipe**. How are you doing the error handling? And please show an MRE as well, the code is hard to decipher and it could help to have an additional more minimal example. -- Ah now seeing popen(). You probably want proc_open() as you can bind input, output and the diagnostics on their own stream there and track is accordingly. – hakre Commented Mar 31 at 5:08
hello I was able to get that resolved and i've updated my question. thank you. @hakre – Adekunle Adeyeye Commented Mar 31 at 9:13
That's great to read! I'd suggest one more thing though: Please place it as an answer to your own question (encouraged!) instead of editing it into the question as it deserves to be an answer!. If in doubt please see Can I answer my own question? (Q&A Help) – hakre Commented Mar 31 at 10:31
And before I fet it: It's also good to have the text of the screenshot instead of the screenshot alone so it can be searched and also read. As it shows from a terminal this should be easy to copy and paste (in general text is preferred over images even albeit OCR gets better every day). – hakre Commented Mar 31 at 10:37
Yes i was going to do that, but my solution is not complete yet. I can't get any transcriptions even while the stream runs successfully. please can you help with that @hakre – Adekunle Adeyeye Commented Mar 31 at 10:48

Finally solved it.

To generate transcripts of an audio from a live source (e.g online radio, e.t.c) using Google cloud speech-to-text API V2 & PHP.

Follow the installation requirements on the google documentation page and then use this code below.
