Android ffmpeg. Linker command failed with exit code 1
8 juin 2017, par Wilsom SandersI’m trying to build ffmpeg static libraries and link them to an android project in order to implement a video player. Goal is to make a player capable of receiving video file from various sources similar to p2p file sharing networks. (target api is 21 level which is 1 level short from supposed official solution with MediaSource)
I managed to compile ffmpeg from this repo (all the code used as-is) but later i got stuck on a linking problem. Whenever I try to compile I get list of ffmpeg methods called in my code and a short eloquent message :
Linker command failed with exit code 1
I have no clue how to pass -v flag to the linker in android studio. Would be great if somebody hinted me that.
I use android studio, build with gradle and cmake.

ffmpeg Command in Docker with Rust Tokio Closes Warp Server Connection (curl 52 Error)
3 juin 2024, par user762345I’m encountering an issue where executing an ffmpeg concatenation command through Rust’s Tokio process in a Docker container causes subsequent HTTP requests to fail. The error occurs exclusively after running the ffmpeg command and making immediate requests, resulting in a “curl 52 empty response from server” error with the connection being closed. Notably, this issue does not occur when running the same setup outside of Docker. Additionally, if no HTTP requests are made after the ffmpeg command, the curl 52 error does not occur.


Here is the verbose curl output of my minimum reproducible example (see below).


curl -v "http://localhost:3030"
* Trying 127.0.0.1:3030...
* Connected to localhost (127.0.0.1) port 3030 (#0)
> GET / HTTP/1.1
> Host: localhost:3030
> User-Agent: curl/8.1.2
> Accept: */*
> 
* Empty reply from server
* Closing connection 0
curl: (52) Empty reply from server


Here are Docker logs from my minimum reproducible example (see below). The wav files are concatenated successfully, then the container appears to rebuild.

What I have tried :
I tried using different web frameworks (Warp, Actix-web) and request crates (reqwest, ureq). I also tried running the setup outside of Docker, which worked as expected without any issues. Additionally, I tried running the setup in Docker without making any HTTP requests after the ffmpeg command, and the connection closed successfully without errors. I also tried posting to httpbin with a minimal request, but the issue persisted.


Minimum reproducible example :


main.rs


use warp::Filter;

 .await;

 } else {

 return Ok(warp::reply::with_status("Failed to concatenate WAV files", warp::http::StatusCode::INTERNAL_SERVER_ERROR));
 }
 },
 Err(e) => {
 error!("Failed to execute ffmpeg: {:?}", e);
 return Ok(warp::reply::with_status("Failed to execute ffmpeg", warp::http::StatusCode::INTERNAL_SERVER_ERROR));
 }
 }

 // ISSUE: Connection closes with curl: (52) Empty reply from server
