Why each option
H.264 is the industry-standard video codec for streaming, providing high compression efficiency and broad compatibility across devices and platforms.
AAC-LD (Advanced Audio Codec - Low Delay) is an audio codec optimized for low-latency voice communication, not a video codec and therefore irrelevant to a video streaming solution.
G.729 is a narrowband audio compression codec designed for VoIP telephony at 8 kbps - it encodes audio only and has no video compression or streaming capability.
H.264 (AVC, MPEG-4 Part 10) is the most widely adopted video compression standard for streaming solutions, delivering high-quality video at low bitrates and supported natively by browsers, mobile devices, and streaming platforms. It achieves a significantly better compression ratio than older codecs while maintaining visual fidelity, making it optimal for bandwidth-constrained delivery environments.
G.711 is a PCM audio codec used in traditional telephony and VoIP for uncompressed audio at 64 kbps - it is audio-only and completely unrelated to video streaming.
