| Overview |
| It is a multimedia container file format which is used over the internet to provide digital video content to the users. Digital video content includes TV shows or series, movies; etc. Adobe Flash Player 6 and new versions provide support to it. To play flash video from Personal Computer and online websites we need an FLV player. Although, Apple iOS does not support Flash, yet, with the help of additional software, one can play flash videos. Also, it is a common platform for various websites that allows video streaming such as YouTube, Yahoo! Video, Metacafe, Hulu; etc . With the help of screen capturing and other recording programs, screen recording is possible for flash videos. Furthermore, it also supports a screen share or screen cast. |
| Technical description |
| FLV files mostly have video bitstreams which are one of the variants of H.263 Standard and it is named as Sorenson park(FourCC FLV1). The SWF files and this extension uses the identical way to encode data. There are two variants available for screen casting. First one is lossy as it reduces colour depth or bit depth (number of bits used to indicate the colour of one pixel) and compresses the data. The second type is only compatible with Flash Player 8 and the newer versions. Both these aforesaid kinds are based on bitmap tile. Uncompressed Audio or ADPCM format audio is also supported by it. This format has header and packets in its video structure. A standard header includes signature, version, flags and header size. |

| Overview |
| It is a format for audio files which compresses the audios using lossy compression. It neglects the redundant information which can not be processed by the human ear. Internet Engineering Task Force (IETF) has standardized this format. It has superseded the Vorgis and Speex. It offers low latency i.e. there is a less delay in the signal when it enters the system and when it emerges out, this results in real-time interactive communication like video conferencing. Due to its good audio quality, it is widely used by in various listening tests. |
| Technical description |
| OPUS has good compatibility with low-end embedded processors as it is less complex. Ranging from 6kbps to 510kbps, it can support both variable and constant bitrate coding. Also, the frame size from 2.5ms to 60ms is supported by this codec. It works smoothly and maintains stability (by avoiding the distortion) while mixing of packets from distinct streams. Speech, Hybrid and pure-CELT are the three different methods used for encoding the audios of varied frequencies. For compressing the Speech up to 8kHz, SILk is used which is an audio compression developed by Skype Limited. The next mode, Hybrid uses CELT to compress the audio files above 8kHz frequency or for wider bandwidth and frame sizes 10ms and 20ms are supported by this mode. CELT(Constrained Energy Lapped Transform) is an open and free audio compression format which is especially used in communication that requires low latency. For general audio, the last mode pure-CELT is used. CELT is used for frame sizes which are less than 10ms. |
