How to fix av_interleaved_write_frame() broken pipe error in php
31 mars, par Adekunle AdeyeyeI 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

How can I build a custom version of opencv while enabling CUDA and opengl ?
1er avril, par JoshI have a hard requirement of python3.7 for certain libraries (aeneas & afaligner). I've been using the regular opencv-python and ffmpeg libraries in my program and they've been working find.


Recently I wanted to adjust my program to use h264 instead of mpeg4 and ran down a licensing rabbit hole of how opencv-python uses a build of ffmpeg with opengl codecs off to avoid licensing issues. x264 is apparently opengl, and is disabled in the opencv-python library.


In order to solve this issue, I built a custom build of opencv using another custom build of ffmpeg both with opengl enabled. This allowed me to use the x264 encoder with the VideoWriter in my python program.


Here's the dockerfile of how I've been running it :

My trouble now, is I've been considering running parts of my program on my GPU, it's creating graphics for a video after all. I have no idea how to edit my Dockerfile to make the opencv build run with CUDA enabled, every combination I try leads to issues.


How can I tell which version of CUDA, opencv and ffmpeg are compatible with python 3.7 ?

ffmpeg pipe process ends right after writing first buffer data to input stream and does not keep running
6 mai, par Taketo MatsunagaI have been trying to convert 16bit PCM (s16le) audio data to webm using ffmpeg in C#.
But the process ends right after the writing the first buffer data to standard input.
I has exited with the status 0, meaning success. But do not know why....
Could anyone tell me why ?
