What is OGV?
OGV is a video file extension for media stored in the Ogg container, typically using Theora video with Vorbis or Opus audio. Developed by Xiph.Org, OGV is open and royalty-free, making it attractive for web distribution and projects that avoid patent-encumbered codecs. As a container, OGV can hold metadata, subtitles, and multiple streams, but real-world files are most often Theora+Vorbis. Playback is widely supported by VLC, mpv, and modern browsers like Firefox and Chrome; however, some platforms prefer MP4/H.264, so creators often transcode to MP4 or WebM for maximum compatibility. Theora encoding is less efficient than H.264/HEVC or AV1 at the same quality, but it remains simple and predictable. OGV works well for open-source assets, archives, and lightweight web video.
What is μ-law (MULAW)?
μ-law (often written mulaw or u-law) is a companding algorithm used in telephony and VoIP to encode audio with ITU-T G.711. It maps linear PCM to a logarithmic scale, squeezing a wide dynamic range into 8-bit samples at 8 kHz (64 kbps). Using a compression parameter μ=255, it preserves low-level speech detail while keeping implementation simple and latency negligible. μ-law is standard in North America and Japan; Europe typically uses A-law. You’ll encounter it in .wav files tagged G.711 μ-law or raw headers like .ulaw/.mulaw. It’s excellent for speech over the 300–3400 Hz band, call recording, SIP trunks, and PBX systems, but not ideal for music or wideband audio. Common conversions include μ-law ↔ linear PCM, Opus, or AAC for modern streaming.
