It’s easy now to get in a rush and simply install ffmpeg/libav from the package sources and call it a day. Right now, just one of the two pillars (namely nginx and ffmpeg) are ready to support the roof (the webcam streams). Sudo service nginx restart Step 5 – Installing ffmpeg with OpenMAX H.264 GPU acceleration module Step 1 – Preparationsīefore beginning, make sure that your system is up to date and has all the necessary packages installed. This step by step guide will show all the taken steps and points out all the important actions. A Raspberry Pi 3 Plus was used to process the two video streams from the webcams using hardware acceleration and output them into a neat und clean website. To overcome this issue, two Logitech E3500 USB-Webcams, alongside with a lamp were placed inside the enclosure to monitor the printing using live streaming. Unfortunately this solution had a serious downside: It wasn’t possible to observe the Print while in process, since the necessary door-opening would have released the warm air. In Order to steadily surround a 3D Printer with warm air, a enclosure was built to keep the air near the printer to prevent plastic cracks and warping. mp4 file using H.264 encoder.The described tutorial is only applicable up to the Raspberry Pi 3B+ running Raspberry Pi OS 10 Buster, since the necessary OpenMAX IL API is only supported up to this version. I just want to encode a single 4K image into a. err 80001018 (-2147479528) on line 561Įrror initializing output stream 0:0 - Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or heightĬommand used: ffmpeg -i /media/pi/pic_1_org.png -c:v h264_omx -c:a copy -b:v 1500k outputfile.mp4 configure -arch=armel -target-os=linux -enable-gpl -enable-omx -enable-omx-rpi -enable-nonfreeįollowing the link, (RPi)-Compile-FFmpeg-with-the-OpenMAX-H.264-GPU-accelerationīut while executing the encoding command after building and installing the ffmpeg with those configuration properly, I am getting the following error Using _encode Compiling FFmpeg source enabling the configurations sudo. I am trying to enable the hardware support for H264 encoding on raspberry pi 4B model.
