FFmpeg Media Info Skill
Extract and analyze media file metadata using ffprobe and ffmpeg.
When to Use
- Get video/audio file properties
- Check codec information
- Verify resolution and bitrate
- Analyze stream details
- Debug media file issues
Basic Info Commands
# Show all file info
ffmpeg -i input.mp4
# JSON format (detailed)
ffprobe -v quiet -print_format json -show_format -show_streams input.mp4
# Simple format
ffprobe -v quiet -print_format json -show_format input.mp4
Duration
# Get duration in seconds
ffprobe -v error -show_entries format=duration \
-of default=noprint_wrappers=1:nokey=1 input.mp4
# Duration with timestamp format
ffprobe -v error -show_entries format=duration \
-of default=noprint_wrappers=1:nokey=1 -sexagesimal input.mp4
Resolution
# Get video resolution
ffprobe -v error -select_streams v:0 \
-show_entries stream=width,height \
-of csv=s=x:p=0 input.mp4
# Get resolution as JSON
ffprobe -v error -select_streams v:0 \
-show_entries stream=width,height \
-of json input.mp4
Bitrate
# Get overall bitrate
ffprobe -v error -show_entries format=bit_rate \
-of default=noprint_wrappers=1:nokey=1 input.mp4
# Get video bitrate
ffprobe -v error -select_streams v:0 \
-show_entries stream=bit_rate \
-of default=noprint_wrappers=1:nokey=1 input.mp4
Codec Information
# Video codec
ffprobe -v error -select_streams v:0 \
-show_entries stream=codec_name,codec_long_name \
-of default=noprint_wrappers=1 input.mp4
# Audio codec
ffprobe -v error -select_streams a:0 \
-show_entries stream=codec_name,codec_long_name \
-of default=noprint_wrappers=1 input.mp4
Sample Rate and Channels
# Audio sample rate
ffprobe -v error -select_streams a:0 \
-show_entries stream=sample_rate \
-of default=noprint_wrappers=1:nokey=1 input.mp4
# Audio channels
ffprobe -v error -select_streams a:0 \
-show_entries stream=channels \
-of default=noprint_wrappers=1:nokey=1 input.mp4
Stream Count
# Count video streams
ffprobe -v error -select_streams v -show_entries stream=index \
-of csv=p=0 input.mp4 | wc -l
# Count audio streams
ffprobe -v error -select_streams a -show_entries stream=index \
-of csv=p=0 input.mp4 | wc -l
Frame Rate
# Get frame rate
ffprobe -v error -select_streams v:0 \
-show_entries stream=r_frame_rate \
-of default=noprint_wrappers=1:nokey=1 input.mp4
Notes
- Use
-v errorto suppress warnings -of jsonfor structured output-select_streamsto target specific streams (v:0 for first video, a:0 for first audio)
