Banana Pi BPI-CM5: Amlogic A311D2 Compute Module with Raspberry Pi CM4 Compatibility · File : bpi-cm5-mipi-camera-capture-ffmpeg-9.ino · Language : bash · Use case : Capturer et sauvegarder un flux vidéo depuis une caméra MIPI-CSI connectée via GStreamer ou FFmpeg.

Script to record 1080p video using the Amlogic A311D2 MIPI-CSI 4-lane camera interface via FFmpeg.

This script uses the BPI-CM5 MIPI-CSI interface to capture video. Ensure the camera driver is loaded in Armbian/Ubuntu. Check devices with 'v4l2-ctl --list-devices'. Execution requires FFmpeg and V4L2 utilities. The yuyv422 input format is standard for MIPI sensors.

# BPI-CM5 MIPI Camera Capture Example
# Requires: v4l-utils, ffmpeg
# Hardware: 1x MIPI CSI Camera connected to CSI0 port

# 1. Verify camera devices (usually /dev/video0 or /dev/video1)
if [ ! -e /dev/video0 ]; then
    echo "Error: /dev/video0 not found. Check camera connection in Armbian."
    exit 1

# 2. Define capture parameters
RESOLUTION="1920x1080"
FRamerate=30
OUTPUT_FILE="bpi_cm5_video_$(date +%Y%m%d_%H%M%S).mp4"

# 3. Capture using FFmpeg
# Note: On Amlogic platforms, you might need to enable the media controller first
# v4l2-ctl --device=/dev/media0 --set-dv-bt-timings query 0

echo "Starting capture from /dev/video0 to $OUTPUT_FILE..."
