biim
An example for Apple Low Lantency HLS Packager and Origin
Feature
- MPEG-TS Demuxing and Apple LL-HLS Packaging in pure Python3 (using asyncio)
- Packaging MPEG-TS stream to HLS media segment (MPEG-TS or fmp4)
main.py: Packaging MPEG-TS stream to MPEG-TS segment (for H.264/AVC, AAC, ID3)- Support TIMED-ID3 Metadata PassThrough
fmp4.py: Packaging MPEG-TS stream to fmp4 segment (for H.265/HEVC, AAC, ID3)- Support TIMED-ID3 Metadata to EMSG-ID3 Conversion
- Support LL-HLS Feature (1s Latency with HTTP/2, 2s Latency with HTTP/1.1)
- Support Blocking Request
- Support EXT-X-PRELOAD-HINT with Chunked Transfer
- NOTE: HTTP/2 is currently not Supported. If use with HTTP/2, please proxing HTTP/2 to HTTP/1.1.
- In Memory (On the fly) LL-HLS Serving
- Not use disk space for LL-HLS Delivery
Dependency
- aiohttp
