Video displays first frames and black/grey only
This is the symptom of a slow decoding, and this is especially the case with high bitrate H264 or HEVC.
If you're using VLC < 3.0, you need turn on hardware acceleration. Preferences -> Input Codecs -> Hardware Acceleration.
Is your Graphic card able to accelerate decoding ?
For 4K H264
- Quick Sync 4 (Intel Broadwell ~)
- PureVideo HD 5 cards (Nvidia GT 520 ~)
- UVD 5.0 cards (AMD Radeon R9 ~)
For HEVC
- Quick Sync 5 (Intel Skylake ~)
- PureVideo HD 7 cards (Nvidia GTX 950 ~, or GTX 750 SE)
- UVD 6.0 cards (AMD Radeon Rx300 ~)
For HEVC 10bit
- Quick Sync 6 (Intel Kaby Lake ~)
- PureVideo HD 7 cards (Nvidia GTX 950 ~, or GTX 750 SE)
- UVD 6.0 Fiji/Carrizo cards (AMD Radeon Rx400 ~)
