Download File 1 (1).mp4

This file is slightly different from the file obtained with -f , although the streams seem to be the same. I tried both on a video: -f mp4, then -f 137+140 (manually choosing the best audio and video). ffprobe says this about the file obtained with -f mp4:

Download File 1 (1).mp4

I have used Record Screen in Stream to create several videos. Some are mp4 format and some are webm. Unfortunately, I cannot edit the webm files because that format is not supported by Photo or Movie Maker, our available editing apps. I have two questions:

I believe your Stream video will download as a .webm file type only when the Stream video hasn't finished 'rendering' or processing on page. Once this process has been completed, the video will download as an .mp4 format.

@Anonymouse I don't know about your reply if it is rendering or processing, but I noticed that for every video that I make any edit (trim, add a thumbnail, or rename) Stream then switches over to making it able to download as an MP4. Similar to the comment by @Jerry Xu Is that what the deal is? Make any edit to get it to download as an MP4. That is a dumb microsoft glitch. Most everybody I know wants it in the more compatable MP4 format.

Per my test, all the videos are created as webm files so I am not sure about your question one. And for your question 2, have a try to trim a part of that video like 2 seconds within microsoft stream and then try to download it again. This time it downloads in mp4 format.

Click the Start menu. ... Type "folder options" (without the quotes). ... A dialog box with the title "Folder Options" will appear. ... Click to uncheck the box for "Hide extensions for known file types". Click the "OK" button at the bottom of the dialog box. Now to just right click on the file and select rename.

You're right this is stupidly simple. I renamed my Stream on SharePoint web recording from .webm to .mp4, uploaded to a different video streaming platform and it worked. Makes me wonder why it just doesn't save the file as .mp4 to begin with...

Checking this again after your comment @Kerr, Cecile , I find that from the Stream UI, for a video I recorded in Teams, I can click the three dots by the "copy to" button, and download and for me the video does now download as mp4

This article lists the multimedia file types that are supported by Windows Media Player 12. (How to determine your version of Windows Media Player).Note: Additional file formats might be supported if you install new codecs in Windows. For more information, see Codecs: frequently asked questions.

Advanced Systems Format (.asf)The Advanced Systems Format (ASF) is the preferred Windows Media file format. With Windows Media Player, if the appropriate codecs are installed on your computer, you can play audio content, video content, or both, that is compressed with a wide variety of codecs and that is stored in an .asf file. Additionally, you can stream audio and video content with Windows Media Services, or you can package that content with Windows Media Rights Manager.ASF is an extensible file format that stores synchronized multimedia data. It supports data delivery over a wide variety of networks and protocols. It is also suitable for local playback. ASF supports advanced multimedia capabilities including extensible media types, component download, scalable media types, author-specified stream prioritization, multiple language support, and extensive bibliographic capabilities that include document and content management.Typically, ASF files that contain audio content that is compressed with the Windows Media Audio (WMA) codec use the .wma extension. Similarly, ASF files that contain audio content, video content, or both, that is compressed with Windows Media Audio (WMA) and Windows Media Video (WMV) codecs use the .wmv extension. Finally, content that is compressed with any other codec use the generic .asf extension. For more information about ASF, visit the following Microsoft Web site:

Windows Media Audio (.wma)Windows Media Audio (.wma) files are Advanced Systems Format (.asf) files that include audio that is compressed with the Windows Media Audio (WMA) codec. By using a separate extension, users can install multiple players on their computer and associate certain players with the .wma extension for playback of audio-only sources.

Windows Media Video (.wmv, .wm)Windows Media Video (.wmv) files are Advanced Systems Format (.asf) files that include audio, video, or both compressed with Windows Media Audio (WMA) and Windows Media Video (WMV) codecs. By using a separate extension, you can install multiple players on your computer and associate certain players with the .wmv extension for playback of audio and video sources.

Advanced Stream Redirector (.asx)Advanced Stream Redirector (.asx) files, also known as Windows Media Metafiles, are text files that provide information about a file stream and its presentation. ASX files go beyond the simple task of defining playlists to provide Windows Media Player with information about how to present particular media items of the playlist.Windows Media Metafiles are based on XML syntax and can be encoded in either ANSI or UNICODE (UTF-8) format. They are made up of various elements with their associated tags and attributes. Each element in a Windows Media metafile defines a particular setting or action in Windows Media Player.ASX files can point to any media file type that Windows Media Player recognizes and supports.For more information about Windows Media Metafiles, visit the following Microsoft Web site:

Windows Media Redirector (.wmx)Versions of Windows Media Player that support this file type: Windows Media Redirector (.wmx) files are Windows Media Metafiles that reference Windows Media Audio (.wma), Windows Media Video (.wmv) files, or both.

Windows Media Player Playlist (.wpl)Windows Media Player Playlist (.wpl) files are client-side playlists that are written in a proprietary format. Microsoft introduced this file format in Windows Media Player 9 Series. The .wpl format can create dynamic playlists, whereas .asx and .m3u formats cannot. In Windows Media Player 9 Series, the auto playlist feature uses the .wpl format. The .wpl format is the default file format used for playlists that you save in Windows Media Player 9 Series.

In Microsoft Windows XP Media Center Edition, Microsoft introduced the *.dvr-ms file format for storing recorded TV content. Similar to *.asf files, *.dvr-ms file enhancements permit key Personal Video Recorder (PVR) functionality, including time-shifting, live pause, and simultaneous record and playback. Video contained in a *.dvr-ms file is encoded as MPEG-2 video stream, and the audio contained in the *.dvr-ms file is encoded as MPEG-1 Layer II audio stream.To play back unprotected *.dvr-ms files on Windows XP-based computers, you must have the following software and hardware components:

Windows Media Download (WMD) packages combine Windows Media Player skin borders, playlist information, and multimedia content in a single downloadable file that uses a .wmd extension. A .wmd package can include a whole album of music videos that also displays advertising in the form of graphical branding and links to an online music retailer Web site.To download a .wmd package from a Web site, click the link to the package. When the package is downloaded to your computer, Windows Media Player automatically extracts the files that are contained in the package, adds the playlists in the package, adds the content to Media Library, displays the border skin in theNow Playing pane of Windows Media Player (in full mode), and then plays the first item in the playlist. For more information about .wmd files, visit the following Microsoft Web site:

Audio Video Interleave (AVI) is a special case of Resource Interchange File Format (RIFF). AVI is defined by Microsoft. The .avi file format is the most common format for audio and video data on a computer.Audio content or video content that is compressed with a wide variety of codecs can be stored in an .avi file and played in Windows Media Player, if the appropriate codecs are installed on the computer. Video codecs that are frequently used in .avi files include the following codecs:

MPEG-1 (.mpeg, .mpg, .m1v)This standard permits the coding of progressive video at a transmission rate of about 1.5 million bits per second (bps). This file format was designed specifically for use with Video-CD and CD-i media. The most common implementations of the MPEG-1 standard provides a video resolution of 352x240 at 30 frames per second (fps). When you use this standard, you receive a video that is slightly lower-quality than typical VCR videos.Files that use the .m1v extension typically are MPEG-1 elementary streams that contain only video information. Files that use .mpg or .mpeg extensions typically are MPEG-1 system streams that contain MPEG-1-encoded video and MPEG-1 Layer II (MP2)-encoded audio.However, MPEG-1 system streams do not exclusively use the .mpg and .mpeg extensions. MPEG-2 program streams also frequently use .mpg and .mpeg file extensions, but they contain MPEG-2-encoded video. Because Microsoft Windows operating systems provide only an MPEG-1 video decoder, Windows Media Player cannot play MPEG-2 program streams without an additional MPEG-2 video decoder (also known as a DVD decoder pack) installed. For more information about purchasing DVD decoder packs, visit the following Microsoft Web site:

Unix Audio (.au) files are UNIX-generated sound files.A sound (.snd) file is an interchangeable sound file format that is used on Sun, NeXt, and Silicon Graphics computers. The file typically contains raw sound data that is followed by a text identifier.

Windows uses the Wave Form Audio (WAV) file format to store sounds as waveforms. One minute of Pulse Code Modulation (PCM)-encoded sound can occupy as little as 644 kilobytes (KB) or as much as 27 megabytes (MB) of storage. This size of the storage space depends on the sampling frequency, the type of sound (mono or stereo), and the number of bits that are used for the sample.Similar to the AVI and ASF format, WAV is only a file container. Audio content that is compressed with a wide variety of codecs and that is stored in a .wav file can be played back in Windows Media Player if the appropriate codecs are installed on the computer. The most common audio codecs that are used in .wav files include Microsoft Adaptive Differential Pulse Code Modulation (MS ADPCM) and uncompressed Pulse Code Modulation (PCM). 041b061a72
