Container Analysis Examples

​
Basic Container Detection

curl -G https://api.probe.dev/v1/probe/file \
  --data-urlencode "token=${PROBE_API_TOKEN}" \
  --data-urlencode "only=mediainfo" \
  --data-urlencode "url=https://example.com/video.mp4"

​
Detailed Stream Analysis

curl -G https://api.probe.dev/v1/probe/file \
  --data-urlencode "token=${PROBE_API_TOKEN}" \
  --data-urlencode "only=ffprobe" \
  --data-urlencode "url=https://example.com/video.mkv" \
  --data-urlencode "ffprobe[show_format]=true" \
  --data-urlencode "ffprobe[show_streams]=true"

​
Best Practices

​
Container Selection

  1. Choose based on distribution method - Web, broadcast, or production
  2. Consider codec compatibility - Not all containers support all codecs
  3. Think about future needs - Expandability and format longevity
  4. Account for target devices - Player/device compatibility

​
Quality Considerations

  • Overhead - Some containers add more metadata overhead
  • Seek performance - Index structure affects scrubbing/seeking
  • Streaming efficiency - Fragmentation and structure impact streaming
  • Error resilience - Some formats handle corruption better

​
Troubleshooting

​
Common Container Issues

IssueCauseSolution
Playback failsUnsupported containerCheck device/player compatibility
Poor seekingMissing indexRe-mux with proper indexing
Large file sizeInefficient containerChoose more efficient format
Streaming problemsNon-streaming containerUse streaming-optimized format

​
Container Validation

# Check if container is streaming-optimized
ffprobe -show_format video.mp4 | grep "start_time\|duration"

# Verify container integrity
ffprobe -v error -show_entries format=format_name video.mp4
Container format choice significantly impacts compatibility, streaming performance, and file size. Choose the appropriate format based on your specific use case and target platforms.
