Building FFmpeg with NVIDIA GPU Hardware Acceleration in docker image, cannot load libnvcuvid.so.1 and libnvidia-encode.so.1
22 mars 2023, par konovificationI'm trying to build FFmpeg with NVIDIA GPU Hardware Acceleration following these instructions : https://docs.nvidia.com/video-technologies/video-codec-sdk/ffmpeg-with-nvidia-gpu/index.html#compiling-for-linux. The Docker image I'm using is

input/output error with ffmpeg using an input URL in docker
12 décembre 2023, par GrimouI need to use ffmpeg to listen to an rtmp url within a running docker container using ffmpeg.
my ffmpeg command is quite simple :
ffmpeg -listen 1 -i rtmp://localhost:1935/live/app ./output.wav

ffmpeg seems to start correctly and listen to the url.


But, when I start the stream (using OBS Studio) I have an input/output error. Here is the logs (with debug log level)


❯ ffmpeg -loglevel debug -listen 1 -i rtmp://127.0.0.1:1935/live/app ./output.wav

The last 3 lines only appear when I start the stream.


It doesn't seems to be a permission problem with the file system, since using
ffmpeg -i ./test.mp4 ./output.wavworks inside the container.

I also did not find any problem with the network. I am currently using
network_mode: "host"in my docker_compose.yml and the logs show that it did receive data before the error appear.

It also doesn't seem to be a problem with the ffmpeg command, since the exact same command works when using it without docker involved.


What else could be the problem ?


here is my docker_compose.yml


version: '3'

services:
 ffmpeg-container:
 build:
 context: .
 network_mode: "host"
 tty: true # Allocate a pseudo-TTY for interactive use



Dockerfile


FROM python:3

# Install ffmpeg
RUN apt-get update && apt-get install -y ffmpeg

# Create a working directory
WORKDIR app

# Copy the Python script to the container
COPY app.py .
COPY test.mp4 .

Can anyone help me identify and fix the problem with this command ? I want to loop the video infinitely on the RTSP server. I've tried variations with different formats (e.g., mp4 and ts), but the issue persists.


Any insights into resolving this error would be greatly appreciated.
