TS is a video format used for storing video on a DVD. It can compress video data using the standard MPEG-2. The files are often saved as multiple files on a DVD and be opened by various software DVD players and video editing tools.

TL mp4

MP4, also known as MPEG4 is mainly a video format that is used to store video and audio data. Also it can store images and subtitles. Normally it is used to share videos over internet. MP4 can embed any data over private streams. Streaming information is included in MP4 using a distinct hint.

DV is a video storing format that stores digital videos. It is a raw format of digital video that is used mostly in video cameras. This format compresses the video while storing but the audio file is not compressed. It uses intraframe video compression for compressing videos frame-by-frame.

GIF is an image format that supports animated images. It can adapt 256 colors and uses lossless compression technique to contain images. It can also contain texts. It can contain low sized image animation. So it is frequently used in web publishing. It applies LZW compression algorithm to compresses low colored images.

TL;DR: MP4 is used when the video site stores more metadata in the video than FLV supports, or uses an audio codec that FLV doesn't support. FLV's simplicity and for-streaming design makes it a good choice if you don't have a good reason to use MP4.

As for flash's timeline scrubbing, I have no idea why it does that since I never coded flash, but it's possible that it's a knob it uses, or something that works specifically with adobe's streaming server in order to seek in the file. It also works as a way to stop the pesky user from keeping the file on his disk.

There are fundamental differences between the FLV and MP4 (aka isomedia) containers. FLV was devised by Adobe from the start as a streaming container, and it's really damn simple. All it does is send a video packet, then audio packet, then video packet... However, it only supports very few codecs, and no metadata other than timestamps in miliseconds. Unless you need MP4-specific features, you would do just fine with FLV.

ISO media, on the other hand, is based on Apple's MOV container. It's separated in atoms, and there is a particular atom, moov, that needs to be decoded before any other atoms can be read. The issue you're having with MP4 is because the moov atom is written at the end of file, which is a lot easier to do for encoding programs. There are tools, such as qtfaststart, which will do the necessary munging to put the moov atom at the beginning of the file. Thus, the file will start playback as soon as it has data, instead of needing to be fully downloaded before starting.

If you use a mov container, it streams out of the box with no need to install modules or place into a flv container and use a module. Just my thoughts. Use mov and add the appropriate mime type - done.

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.

Video, if employed as part of a more comprehensive digital strategy, is an effective tool for lead generation, customer engagement, brand creation and SEO. As a consequence, sharing videos on social media is core to the digital marketing strategy of many businesses, for instance in the real estate industry.

Frustratingly, uploading video files to social media sites can be a cumbersome experience. After you already spent considerable time recording and editing the clip you want to put up on YouTube, Vimeo or another video sharing service of your choice, uploading the file should be a quick last step.

This is especially true if the video you want to share on social media comes straight off your camera or smartphone where it usually gets recorded in the highest possible resolution, fps, bit rate and quality setting using a codec that is not optimised for smallest file size and highest image quality.

It also happens if you use high quality recording equipment and professional editing tools where the exported file can often be optimised some more for quicker online sharing without noticeable loss of quality.

The way this works in more detail is that H.264 encodes video files much more efficiently than most other commonly used codecs. It comes with a range of quality profiles that video converter apps such as clipchamp use behind the scenes to influence the trade-off between file size and image quality.

Almost every document about h264 tells me that it consists of NAL packets. Okay. Almost everywhere told to me that the packet should start with a signature like 00 00 01 or 00 00 00 01. For example, ,

Notice that the AVI bytes include... - a note of item's total size (AD 24 00 00... or reverse for Little Endian : 00 00 24 AD)- followed by item data (00 00 24 A9 65 88 84 27 ... etc ... C5 E2 7D BF).

Next follows the item data, which is the H.264 video frame. By sheer coincidence of formats/bytes layout, it too holds a 4-byte entry for data's size (since your H264 is in AVCC format, if it was Annex-B then you would be seeing start code bytes here instead of size bytes).

I have an HLS stream which plays in the browser. What I want to do is have a URL like /stream.mp4 that plays the livestream back as a fragmented mp4 from the current point in time. This way you could download the stream as a single file and it would work without any js dependencies.

This answer describes how to create a fragmented mp4 when you have all the segments at hand (tl;dr use -movflags frag_keyframe+emptymoov). But I want to do this on the fly so each new HLS segment is converted to an mp4 fragment as soon as it's created.

Edit: I found a way of doing what I wanted, but not through transmuxing mpegts segments to fmp4. It turns out that later versions of HLS do support fragmented mp4 (like DASH does), and FFmpeg provides the -hls_segment_type fmp4 option for this.

As an aside, you can typically view the above metadata within iTunes by doing a Get Info. That is, select the item and press command I (or you can go to iTunes > Edit > Get Info). This brings up all the metadata and you can view the:

Bacteria can exceptionally evolve and develop pathogenic features making it crucial to determine novel pathogenic proteins for specific therapeutic interventions. Therefore, we have developed a machine-learning tool that predicts and functionally classifies pathogenic proteins into their respective pathogenic classes. Through construction of pathogenic proteins database and optimization of ML algorithms, Support Vector Machine was selected for the model construction. The developed SVM classifier yielded an accuracy of 81.72% on the blind-dataset and classified the proteins into three classes: Non-pathogenic proteins (Class-1), Antibiotic Resistance Proteins and Toxins (Class-2), and Secretory System Associated and capsular proteins (Class-3). The classifier provided an accuracy of 79% on real dataset-1, and 72% on real dataset-2. Based on the probability of prediction, users can estimate the pathogenicity and annotation of proteins under scrutiny. Tool will provide accurate prediction of pathogenic proteins in genomic and metagenomic datasets providing leads for experimental validations. Tool is available at:

Pathogenic microbes possess unique virulent factors encoded by their genes present on chromosomal DNA that may exist as pathogenicity islands, or in their extrachromosomal plasmids [1]. High-throughput genomic analysis has shown that there is a significant difference in the genome of pathogenic and non-pathogenic bacteria even within closely-related species [2]. Such differences have been exploited to develop tools which predict pathogenic genes in genomes and metagenomes [3]. In addition to being species-specific or host-specific, pathogenesis processes are multifaceted broadly consisting of virulence, adhesion, invasion, secretion, and drug resistance [4]. As a result, vast differences exist in the protein profile of pathogenic and non-pathogenic bacteria as pathogenic bacteria require proteins which can aid them in survival and proliferation within the host during infection. For example, pathogenic and non-pathogenic Listeria species show significant difference in their proteome [5]. Similarly, pathogenic Mycobacterium tuberculosis and non-pathogenic Mycobacterium smegmatis show differences in porin complexes in their outer membrane [6]. However, many of the putative outer membrane proteins of Mycobacterium tuberculosis have not been yet been identified and characterized [7], many of which may be responsible in its virulence and survival in host cells. 041b061a72
