Video Won't Play At All
Symptoms
Video player shows a black screen, error message, or loading spinner indefinitely.
Common Causes
- Unsupported codec (HEVC in Firefox, VP9 in Safari)
- Corrupted file header
- DRM-protected content without proper license
Solutions
Try a different player or browser. Convert to H.264/MP4 for universal compatibility. Use a video inspection tool to check for file corruption.
Stuttering and Buffering
Symptoms
Video pauses frequently, drops frames, or shows buffering indicators.
Causes
Insufficient bandwidth for the video bitrate, or the device lacks hardware decoding support for the codec.
Solutions
Reduce video resolution or bitrate. Use a codec with hardware decode support. For streaming, implement adaptive bitrate (ABR) that adjusts quality automatically.
Green or Pink Artifacts
Symptoms
Parts of the video show green, pink, or corrupted rectangular blocks.
Causes
GPU hardware decode failure or corrupted video data.
Solutions
Disable hardware acceleration in browser settings. Re-encode the video with a different encoder or settings.
