Anyone know how I can convert a .f4f file back a regular file such as a .mp4. On my Adobe Server I have a live DVR functionaility setup, and in the applications\livepkgr\streams\_definst_\ path I have .f4f files that's been cached that I would like to convert back a .mp4 for archival purposes.

According to Adobe, F4F file is Flash MP4 Video Fragment created and used by Adobe Media Server for HTTP Dynamic streaming. As F4F files are separating video clips and F4F is not a so common video format, it is incompatible with most video media players, portable devices or editing software.

To improve the compatibility, it is a quite good choice to convert F4F to a more popular video format like convert F4F to MP4, convert F4F to AVI, convert F4F to FLV, convert F4F to MP3 and etc. The following article will show you a professional F4F Converter and a step by step guide on how to convert F4F video files on Mac or Windows.

f4f is a non-standard and not a ISO MP4 container.

It is very simple to remux an MP4 ISO by using ffmpeg from the command line. The latest version of ffmpeg will take the HLS .m3u8 stream and convert to to ISO MP4 in real time.

You can have the main.asc call a php script to call ffmpeg, and start recording to a MP4 ISO container on every publish to the livepkgr application.

You can then complete set the server to default dismanagement and duration, as the .f4f's can be discarded, as they are merely inplace to provide a cache store for your clients to watch the live video.

It is then very simple to symlink a directory store from /webroot/vod/ of the MP4 ISO that is immediately replayable through the hls-vod application creating an instant on demand of the content being live streamed to FMS.

Keep in mind that .f4f format is directly playable through many Flash Players on the web, also the hls-vod and hds-vod Apache modules can produce the manifest and playlist .f4m and .m3u8 on the fly with the .f4f as well. I would recommend leaving the files in .f4f as if they become corrupted, they are easily recoverable. Eseentially when you scrub a .f4f to .mp4 losslessly you are removing the interval metadata stored within the file rendering it subsceptible to not being recoverable if something would happen to the media the data is contained on.

It is also a good idea to "rename" the entire contents of a /stream/_definst_/ live stream as the meta data and control files can be used to generate .m3u8 manifests when streaming over HLS and future developments of software come about you will have the entire set of data of the storeed live stream. This is essentialy what the new HLS Packager that is bundled with AMS 5.x.x when taking .mp4 from other sources to generate your manifests and playlists .m3u8 and stream via HTTP HLS.

You can essentially modify the main.asc on interactive and enterprise editions of AMS to simply "Rename" the stream directories, and then sym link the /stream/_definst_/ to the /application/vod/media to directly replay a live stream through RTMP VOD, or hls-vod or hds-vod seamlessly. Renaming the directories is a perfect solution rather than "copying" as the main.asc if copying a large stream will render the "pkgr" application not responsive to immediately rebroadcast a stream until the contents of the directory is copied to another location. You can then pass particular "stream id strings" in which the main.asc can parse and perfom a specific function, as by defualt "record" and "append" modes preform those fucntions as such. append meaning adding to the existing .f4f, and record meaning to erase and start over the .f4f. You could pass a string to rename the directory to what the string parameter contains. i.e. &adbe-rename-mode=rename.to.%"

Hope this helps you utilize the FMS & AMS suites effectively in your application.

Hi,

There is no adobe supported tool to do this. You can try some of the tools available online. I suggest you check ffmpeg, which I think can convert each f4f fragment to a mp4 file.

In future you can publish the stream to another application where you can record the stream on the server as mp4. You'll then have both the mp4 file and f4f fragments.

Thanks,

Hello, how about using FV4PostProcessor1.0? It can convert cached .f4f files into mp4. http://www.adobe.com/products/adobe-media-server-family/tool-downloads.html - Adobe Media Server tools

The F4V post processor is used for post processing of .f4v or .mp4 files created by server side recording in AMS to make them compatible with tools and players like vlcplayer. It does not convert .f4f files to mp4.

Thanks,
