H.264 (AVC) raw bitstream is the elementary video stream with no container around it — what surveillance cameras, some editors and FFmpeg tutorials hand you directly. Wrap it into MP4/MKV for players to accept it.
Typical use: Convert a .h264 dump to MP4 to add timestamps and player compatibility, or extract a raw H.264 stream from MP4 for pipeline use.
About the H.264 format
H.264 (also called AVC) is the video codec the entire internet settled on: Blu-ray, YouTube, broadcast TV, every phone camera. A .h264 file is that codec's raw bitstream with no container — no timestamps, no audio, no metadata, just compressed frames back to back. Cameras and capture pipelines emit it because it is the codec's native shape.
Players struggle with raw streams precisely because there is no container to carry timing information. Wrapping H.264 into MP4 or MKV adds timestamps, duration and (optionally) audio tracks — the picture itself is untouched, since remuxing copies the compressed frames as-is.
Strengths
- ✓ The universal codec — plays everywhere once wrapped
- ✓ Native output of cameras and capture cards
- ✓ Remuxing is lossless (stream copy)
Limitations
- ✗ No container: no timestamps, no audio, no duration
- ✗ Most players refuse or mis-time raw streams
- Compression
- H.264/AVC (lossy)

- Not supported
- Animation
- Video stream only
