What is a 3G2 file?
The 3G2 file format is a multimedia container defined by the 3rd Generation Partnership Project 2 (3GPP2) for use on CDMA2000-based mobile networks. It is structurally similar to the MP4 format but is optimized to minimize storage and bandwidth usage on legacy mobile devices. The format stores video streams typically encoded with MPEG-4 Part 2 or H.263, and audio streams using EVRC, EVRC-B, QCELP, or SMV codecs. 3G2 files are compliant with the ISO base media file format (ISO/IEC 14496-12) but possess extensions specific to the 3GPP2 specifications.
How to open a 3G2 file
While 3G2 was native to early CDMA mobile phones, modern desktop operating systems often lack native support for its specific audio codecs like EVRC. Apple QuickTime Player and Microsoft Windows Media Player may open these files if the appropriate DirectShow filters are installed. For universal compatibility across Windows, macOS, and Linux, the VLC media player is recommended as it utilizes the FFmpeg library to decode 3GPP2 streams without external codec packs.

What is an FLV file?
The FLV (Flash Video) format is a container file format defined by Adobe Systems for delivering synchronized audio and video over the internet via the Adobe Flash Player. It supports various codecs, historically Sorenson Spark and VP6, and later H.264 (MPEG-4 AVC) and AAC audio. FLV files were the dominant standard for web-based streaming video (YouTube, Hulu) during the 2000s, utilizing the RTMP (Real-Time Messaging Protocol) for transmission before being superseded by HTML5 standards.
How to open an FLV file
Since the End-of-Life (EOL) of Adobe Flash Player in 2020, browsers no longer support FLV natively. To play local FLV files, users must utilize third-party media players that maintain legacy codec support, such as VLC Media Player, MPC-HC, or MPV. For editing or conversion, tools like OBS Studio and HandBrake utilize the FFmpeg library to decode and process the container.
