问题 I have a website which is able to play mp4 media (via the <video> tag and via DASH) in every browser except the Samsung Internet browser, which comes as default on Samsung Galaxy phones and probably a lot of other Samsung devices. On a desktop, iPad, or even an ancient HP TouchPad tablet, it works fine. Using other browsers on the same Samsung device (e.g. Chrome), the mp4 media plays fine, so it's not a limitation of Android or the device hardware. I can detect the Samsung browser with

Threads i have checked: mp4box - from one hand i saw this comment that states " You cannot feed MP4Box with some live content. You need to feed

问题 I've got a problem with Chromecast playing MPEG-DASH livestream. The infinite loading occurs because of the lack of UTCTiming tag in manifest. The problem is known to occur with ShakaPlayer. It's the first problem in FAQ: https://github.com/google/shaka-player/blob/master/docs/tutorials/faq.md On chromecast however, i can't access the ShakaPlayer directly (or maybe there is a way that i'm not familiar with).

问题 I have created a video player from the Media Source Extension API . I have split the video and audio from the original.mp4 (1 minute duration) . I have split the video and audio into small 5 second files (12 files in total) . I'm getting each one of them and playing them together. But the video stops playing at around 45-47 seconds. I cannot understand to why the video is stopping/buffering. I cannot understand whether the problem is in the javascript code or the video files? I have uploaded

问题 I'm working with live MPEG-DASH streaming, and I would like to know if there exists a stardard terminology for a given functionality. It's the "live-dvr" functionality. That is, a mix between a live stream and VOD features: a live stream with the seeking bar in the player allowing to watch past stream time. This involves a series of infrastructure tweaks. The term "live-dvr" for this setup is kind of informal, and different parties call it in its own way: "live catch-up", "live-vod", "cached

My Exo player version is 2.9.3 , I tried implementing by following these Stackoverflow Post,Medium Post, but it's bit confusing and some part of the code is deprecated, and saying the truth is that I am a beginner.

问题 I have created fixed length segments for a long MP4 video using Mp4Box. Mp4Box creates a meta info file mv_init.mp4 and segments like mv_1.m4s , mv_2.m4s , … I stream the video using HTML5 Media Source Extensions and the streaming is working properly. The problem is that I am unable to utilize time seeking feature of my HTML5 player . When a user uses the seekbar to seek to another time point, I need to fetch the correct segment file ( mv_{number}.m4s ) for that currentTime . For example:
