The .flv filename extension and the FLV file format are associated with Adobe System's flash player. It is a container format primarily used for content delivery over the internet and other computer networks. It is an open file format and supports delivery of audio and video streams through players that are compatible with the specification. Flash video, or FLV, has been popularized on the internet by video streaming websites that encode their video in this format. Most web browsers have support for the format through web browser plugins with the exception of Google chrome which has native support for the format.
The data compression to get a lossless audio, a file format and an algorithm used is APE, also known as Monkey's Audio. This compression can retain data and not suffer losses during its compression as opposed to the other compressions with losses such as MP3, Musepack, ACC, and Vorbis. It encodes and compresses the audio to reduce transfer time, storage space. The audio extension APE is used for an audio file to track the metadata. The format is available freely for users possessing media players and playback plugins.
FreeFileConvert uses tuned encoding for FLV to APE conversions, preserving clarity while trimming file size. Finished audio streams instantly across phones, tablets, desktops, and modern browsers without extra tweaks.
Upload FLV files from desktop, tablet, or cloud storage, queue multiple jobs, and let the converter finish autonomously. Return whenever convenient to download synchronized APE results on any device you rely on.
Process up to 5 files sized 1000 MB per batch without splitting queues manually. Mixed-format uploads convert together, producing consistent APE audio with dependable progress tracking.
The FLV format is similar to the SWF file format (also owned by Adobe Systems) in the technique used to encode audio and video streams but differs slightly with multi byte storage in big endian byte order. FLV supports a number of codecs including but not limited to On2 VP6 and Sorensen Spark. FLV files can only have a single and synchronized audio and video stream. The format has a header tag followed by alternating blocks of back pointers and tags.
The source code for APE is not considered as an open source. It has a symmetrical algorithm, a process of an encoding comparable decoding which makes the files not suitable for fast players for example Rockbox. To cover this, an independent GPL code is written for and is added in FFmpeg. It also provides limited support to software other than the ones for Windows.
