Muxer
After implementing the VAAPI encoder, a muxer is required to write encoded data to output devices.
Output formats:
- Streamable
- MKV
- MPEGTS
- Not streamable (Seekable output required)
- MP4
- WEBM
Other features:
- Calling init() from a packet source creates a new AVStream for it.
- QIODevice output
- Separate processing thread, no direct write in onPacket()
