Is there any way Power BI/Powershell can export .mp4 file-related data from OneDrive for business and SharePoint Online so as to look at the metadata of the Teams Meeting Recording .mp4 files which can be differentiated from non Teams Meeting recording files? Thanks in advance!

For non-Channel meetings, the recording is stored in a folder named Recordings that's at the top level of the OneDrive for Business that belongs to the person who started the meeting recording.

thanks for your response. There are users who put non Teams meeting recordings in One drive for business and Sharepoint Online under the Recording folder. So how can we differentiate these non Teams meeting recording files from Teams meeting recording ones?

1.Teams meeting recordings' [Sharing] column is automatically displayed as Shared (share with people who joined in this meeting), and (non Teams meeting recordings) .mp4 files are Private by default unless you specify whom to share to.

The format of audio and video media files is defined in two parts (three if a file has both audio and video in it, of course): the audio and/or video codecs used and the media container format (or file type) used. In this guide, we'll look at the container formats used most commonly on the web, covering basics about their specifications as well as their benefits, limitations, and ideal use cases.

WebRTC does not use a container at all. Instead, it streams the encoded audio and video tracks directly from one peer to another using MediaStreamTrack objects to represent each track. See Codecs used by WebRTC for information about codecs commonly used for making WebRTC calls, as well as browser compatibility information around codec support in WebRTC.

While there are a vast number of media container formats, the ones listed below are the ones you are most likely to encounter. Some support only audio while others support both audio and video. The MIME types and extensions for each are listed. The most commonly used containers for media on the web are probably MPEG-4 (MP4), QuickTime Movie (MOV), and the Wavefile Audio File Format (WAV). However, you may also encounter MP3, Ogg, WebM, AVI, and other formats. Not all of these are broadly supported by browsers, however; some combinations of container and codec are sometimes given their own file extensions and MIME types as a matter of convenience, or because of their ubiquity. For example, an Ogg file with only an Opus audio track is sometimes referred to as an Opus file, and might even have the extension .opus. But it's still actually just an Ogg file.

In other cases, a particular codec, stored in a certain container type, is so ubiquitous that the pairing is treated in a unique fashion. A good example of this is the MP3 audio file, which is in fact an MPEG-1 container with a single audio track encoded using MPEG-1 Audio Layer III encoding. These files use the audio/mp3 MIME type and the .mp3 extension, even though their containers are just MPEG.

To learn more about a specific container format, find it in this list and click through to the details, which include information about what the container is typically useful for, what codecs it supports, and which browsers support it, among other specifics.

The 3GP or 3GPP media container is used to encapsulate audio and/or video that is specifically intended for transmission over cellular networks for consumption on mobile devices. The format was designed for use on 3G mobile phones, but can still be used on more modern phones and networks. However, the improved bandwidth availability and increased data caps on most networks has reduced the need for the 3GP format. However, this format is still used for slower networks and for lower-performance phones.

These MIME types are the fundamental types for the 3GP media container; other types may be used depending on the specific codec or codecs in use. In addition, you can add the codecs parameter to the MIME type string to indicate which codecs are used for the audio and/or video tracks, and to optionally provide details about the profile, level, and/or other codec configuration specifics.

Audio Data Transport Stream (ADTS) is a container format specified by MPEG-4 Part 3 for audio data, intended to be used for streamed audio, such as for Internet radio. It is, essentially, an almost bare stream of AAC audio data, comprised of ADTS frames with a minimal header.

The MIME type used for ADTS depends on what kind of audio frames are contained within. If ADTS frames are used, the audio/aac MIME type should be used. If the audio frames are in MPEG-1/MPEG-2 Audio Layer I, II, or III format, the MIME type should be audio/mpeg.

The Free Lossless Audio Codec (FLAC) is a lossless audio codec; there is also an associated simple container format, also called FLAC, that can contain this audio. The format is not encumbered by any patents, so its use is safe from interference. FLAC files can only contain FLAC audio data.

The MPEG-1 and MPEG-2 file formats are essentially identical. Created by the Moving Picture Experts Group (MPEG), these formats are widely used in physical media, including as the format of the video on DVD media.

On the internet, perhaps the most common use of the MPEG file format is to contain Layer_III/MP3 sound data; the resulting files are the wildly popular MP3 file used by digital music devices around the world. Otherwise, MPEG-1 and MPEG-2 are not widely used in Web content.

MPEG-4 (MP4) is the latest version of the MPEG file format. There are two versions of the format, defined in parts 1 and 14 of the specification. MP4 is a popular container today, as it supports several of the most-used codecs and is broadly supported.

The original MPEG-4 Part 1 file format was introduced in 1999; the version 2 format, defined in Part 14, was added in 2003. The MP4 file format is derived from the ISO base media file format, which is directly derived from the QuickTime file format developed by Apple.

When specifying the MPEG-4 media type (audio/mp4 or video/mp4), you can add the codecs parameter to the MIME type string to indicate which codecs are used for the audio and/or video tracks, and to optionally provide details about the profile, level, and/or other codec configuration specifics.

These MIME types are the fundamental types for the MPEG-4 media container; other MIME types may be used depending on the specific codec or codecs in use within the container. In addition, you can add the codecs parameter to the MIME type string to indicate which codecs are used for the audio and/or video tracks, and to optionally provide details about the profile, level, and/or other codec configuration specifics.

The Ogg container format is a free and open format maintained by the Foundation. The Ogg framework also defines patent unencumbered media data formats, such as the Theora video codec and the Vorbis and Opus audio codecs. documents about the Ogg format are available on their website.

While Ogg has been around for a long time, it has never gained the wide support needed to make it a good first choice for a media container. You are typically better off using WebM, though there are times when Ogg is useful to offer, such as when you wish to support older versions of Firefox and Chrome which don't yet support WebM. For example, Firefox 3.5 and 3.6 support Ogg, but not WebM.

The application/ogg MIME type can be used when you don't necessarily know whether the media contains audio or video. If at all possible, you should use one of the specific types, but fall back to application/ogg if you don't know the content format or formats.

The QuickTime file format (QTFF, QT, or MOV) was created by Apple for use by its media framework of the same name. The extension for these files, .mov, comes from the fact that the format was initially used for movies and was usually called the "QuickTime movie" format. While QTFF served as the basis for the MPEG-4 file format, there are differences and the two are not quite interchangeable.

QuickTime files support any sort of time-based data, including audio and video media, text tracks, and so forth. QuickTime files are primarily supported by macOS, but for a number of years, QuickTime for Windows was available to access them on Windows. However, QuickTime for Windows is no longer supported by Apple as of early 2016, and should not be used, as there are known security concerns. However, Windows Media Player now has integrated support for QuickTime version 2.0 and earlier files; support for later versions of QuickTime requires third-party additions.

On Mac OS, the QuickTime framework not only supported QuickTime format movie files and codecs, but supported a vast array of popular and specialty audio and video codecs, as well as still image formats. Through QuickTime, Mac applications (including web browsers, through the QuickTime plugin or direct QuickTime integration) were able to read and write audio formats including AAC, AIFF, MP3, PCM, and Qualcomm PureVoice; and video formats including AVI, DV, Pixlet, ProRes, FLAC, Cinepak, 3GP, H.261 through H.265, MJPEG, MPEG-1 and MPEG-4 Part 2, Sorenson, and many more.

Because QuickTime support is, for all intents and purposes, primarily available on Apple devices, it is no longer widely used on the internet. Apple itself generally now uses MP4 for video. In addition, the QuickTime framework has been deprecated on the Mac for some time, and is no longer available at all starting in macOS 10.15 Catalina. 041b061a72
