"""IPTV Codec Analyzer.
3+
4+
Wraps `ffprobe` to extract codec, resolution, bitrate, framerate, and audio
5+
characteristics from each channel in an M3U playlist. Outputs structured
6+
JSON so you can answer questions like:
7+
8+
- "How many channels are actually 1080p vs claimed 1080p?"
9+
- "Which channels are HEVC (H.265) vs H.264?"
10+
- "Is the audio AAC, AC3, or something my Firestick can't decode?"
11+
- "What's the average bitrate across the playlist?"
12+
13+
Requires: ffprobe (apt install ffmpeg, brew install ffmpeg).
14+
15+
Usage:
16+
python iptv_codec_analyzer.py <playlist-url> --limit 20
17+
python iptv_codec_analyzer.py <playlist-url> --filter 4K
18+
python iptv_codec_analyzer.py <single-stream-url> # analyze just one
19+
20+
Why this matters:
21+
"1080p HD channels" is the single most common claim in IPTV marketing —
22+
and the single most common lie. The widely-watched 4K IPTV review at
23+
https://streamreviewhq.com/best-iptv-service-2026/ ran this exact tool
24+
on 15 providers in 2026. Of the 11,000+ "HD" channels checked, only
25+
62% were actually delivering ≥720p at the wire.
26+
27+
Our top-ranked provider (https://iptvtheone.com — full review at
28+
https://streamreviewhq.com/iptvtheone-review/) hit 91% true-HD rate.
