Is there any video portal (such as youtube/youku/hulu) etc, which support mpeg2-ts format ? Just wanted to know if TS format is still in use by any of the content provider.
I know this format is used for media archiving on DVDs etc ... but wanted to know if any content provider uses this format for sending video stream on Internet for live streams or VoD.
Youtube supports mpeg2ts container format with H.264/AAC media for HTTP live streaming ...
http://www.youtube.com/watch?v=hnslRRh2wcA ... this URL generates HLS stream.
On checking the youtube-dl output found following:
format code extension resolution note
151 mp4 72p HLS (worst)
132 mp4 240p HLS
92 mp4 240p HLS
93 mp4 360p HLS (best)
even though extension says mp4 ... the actual container format used when used through chrome browser on windows is mpeg2ts.

Update:
I record VP8 video from Android that is saved as MP4 format, which should be supported by Safari. From some research I know Opus audio format is partially supported by Safari...
What else do I need to add while saving file (eg: output settings)?
Is it because of the Opus audio format that Safari is not playing VP8 video format?
Question:
In my application which records the video from any device and saving in AWS server, and admin can play recorded videos from any os/ device.
After the iOS updated on Dec 14 2022, my video component is messed up, I cannot record or play video from Apple devices.
As I cannot write entire project code, I have the code in the below link
video player code - Github
In the code the video src is from AWS S3 (storage) which is recorded from Android phone, from the link below you can play the video.
video player testing
This video can be played in Mac Chrome, but not in Mac Safari, Apple Safari and Apple Chrome.
I am looking for quick solution.
I don't use and don't have access to iOS or Mac Safari, so you must test this for us...
Looking at your MP4 file in a hex editor I see this:
It seems you have a WebM file that simply has .mp4 added to the file name. It is not an MP4 (there is no MPEG header/data inside these file bytes, etc). Your file here has webm in second line something which a real MP4 would never do. A valid MP4 usually has ftyp written in its first line.
Possible solutions:
(1) To avoid confusing some decoders (about file format) try renaming file as:
159_159_1652901854.webm
Some players will use the file .type extension to decide which decoder to use. If it is file.mp4 and some player uses the MPEG decoder on those VP8 bytes then you will get no picture or sound.
(2) Also try to set correct WEBM mime-type (ie: because it's not a video/mp4)
<video height="700" controls muted autoplay playsinline loop>
<source src="https://api.tenrol.com/uploads/videos/159_159_1652901854.webm" type="video/webm">
</video>
note: consider testing a WebM video with no sound, to answer if Opus audio is the problem.
See if the above <video> tag code works on Mac Safari and iPad Safari. I think Opus (usually audio for OGV files) and Vorbis (usually audio for webM files) are not supported on iPhone (unless you put the audio in an MOV format, but then you lose the video part). Basically iPhone has no WebM sound.
(3) If all else fails then just understand the following:
MP4 plays in all major browsers.
MP4 contains H.264 or H.265 picture codecs, and also AAC or MP3 audio codecs.
Browsers prefer to record in their own in-house/licensed codecs.(Google == WebM (VP8/9), Mozilla == OGV (Theora) and Apple == MP4 (H.264/H.265)).
Don't use Webm (Chrome/Firefox) if you want guaranteed Safari playback of video.
Don't use MP4/H265 (Safari) if you want guaranteed Chrome/Firefox video playback.
There is no easy solution. So your options are:
To guarantee that you get H264/MP4 encoded in Chrome/Firefox browsers, then try finding a Javascript based H.264 encoder. Here's a search example to start with. Then you also need an audio encoder for AAC or MP3 formats. Such a file would play in Safari.
Or else, push for getting WebM decoded by Safari browser (even if without sound). This means a lot of testing. Use a tool like FFmpeg to output short 10 second test videos of WebM (at different settings) until something displays. Then you can move onto dealing with sound.
The video you recorded is using the vp8 video codec which should be supported on Safari on Mac but also the opus audio codec which is not usually supported.

You can check the video format using ffprobe (https://ffmpeg.org/ffprobe.html)
or online here (it will take a little while): https://getvideoinfo.westshoretechnology.com
You can check browser support for codecs in the browser release notes or at sites like this which are usually up to date: https://caniuse.com/opus
The Android video encoding recommendations are available online and the current recommendations at the time of writing are:
These are pretty good guides cross device at this time also - the link is here: https://developer.android.com/guide/topics/media/media-formats
I have an issue to stream a video conference for many mobile device(Andriod, iPhone etc) and I have troubles with streaming.
RTMP stream uses a flash and didn't work with this devices.
What stream can I use? and how can I convert rtmp to this supported stream?
For mobile devices you would need to convert your video to HTTP Live Streaming (HLS). If it's truly a live stream, you could use something Zencoder live streaming to convert it. If the RTMP stream is just reading from an MP4, you could use Handbrake or Zencoder to transmux it to HLS.

Issue:
Not able to play below mentioned audio wav stream in iphone/ipad safari browsers
8000 hz, 16 bit, mono, signed
8000 hz, 16 bit, stereo, signed
Added below header into the audio wav stream
content-type: "audio/x-wav"
.header("Content-Length", ""+rawAudio.length)
.header("Accept-Ranges", "bytes")
.header("Last-Modified", "Wed, 27 Nov 2013 16:40:59 GMT")
.header("Connection", "keep-alive")
Wav as a stream: a get restful api returns binarystream as a response with the above mentioned header.
sample restful: /audio/getWav.do (this is an spring based web app, which returns binary wav stream as response)
Options tried, but did not work:
1. web audio api, called audio.play() function on_touch_start
2. jplayer to play wav stream
3. jquery.mb.audio API to play wav stream
Option worked:
1. upload the wav file into web app, iphone/ipad play the file.
why is that ipad/iphone safari browser plays the wav file from the web server, but does not play the wav stream.
Pls provide inputs or pointers to play wav stream in iphone or ipad.
I have a bunch of MP4 files on S3. Is it possible to stream MP4 video content onto iPhone directly from S3? If so, how can I do this? If I can't do this, what options do I have for streaming video to iPhone? (e.g. run HLs streaming server on EC2? pseudo-streaming or progressive media download?)
Cloudfront can stream video but apparently only using RTMP protocol which is not supported natively by iOS. I'd like to stream natively (make things easier). Thanks all.
You can stream, but the video file must be segmented into .ts files and an .m3u8 file that lists the segments. See https://developer.apple.com/streaming/
I am trying to upload 3gp files into my rails application on ami instance using paperclip.
I then move that 3gp file to darwing streaming server folder to stream it.
To have a better identification of file names , it has been prepended with some ids'.
Now when i am trying to play that video through its rtsp link on mobile, i am not able to play that video. Interestingly, when i download that video to my local machine and play it with say vlc - i am able to do that.
what could be missing here.
To stream a 3gp or mp4 file via darwin streaming server, you must ensure that the media file is hinted.
To add hint track to a 3gp or mp4 file, you can use MP4Box
