How to play MPEG-DASH with AVPlayer? - ios

I was wondering what could be approach for AVPlayer to stream DASH (Dynamic Adaptive Streaming over HTTP). I saw this AVFoundation (AVPlayer) supported formats? No .vob or .mpg containers? but it looks AVFoundation has no support for DASH.
This is the sample link

How to play .mts file in iOS

Currently im working with a wifi-camera device, which is able to send only videos in .mts format.
As i have investigated in google, it leads to conclusion that it is not possible to play the video in iPhone or may be using Objective C.
Now my problem what is,
There is still many paid applications that allows us to play .mts files
PlayerXtreme is able to run files in almost any video format. It has currently the following formats covered:
3gp, asf, avi, divx, dv, dat, flv, gxf, m2p, m2ts, m2v, m4v, mkv, moov, mov, mp4, mpeg, mpeg1, mpeg2, mpeg4, mpg, mpv, mt2s, mts, mxf, ogm, ogv, ps, qt, rm, rmvb, ts, vob, webm, wm, wmv
See the application: iTunes app
Player i m curently trying is AVPlayer lib
How can i start the coding to get this done in my app also?
Currently I'm trying solve by adding some python scripts to my project as a build.. and calling the same for converting to mp4 format.. anyone worked on py-ObjC Together in XCode pls give some idea..
MTS is a container format. You need to know what the video and audio codecs are, and see whether VideoToolbox and AudioToolbox (the underlying frameworks of AVPlayer) support those codecs.
Assuming H264 for video and AAC or AC3 for audio, libavcodec (part of ffmpeg) supports the MTS container. You can use that to demux the video and audio streams, and then use VTDecompressionSession and AudioQueueNewOutput (I think, I haven’t used that API in a while).

How Does VideoToolbox.framework work?

iOS8 just released beta version, I'm very interested in Video directly Encoding / Decoding.
Video Toolbox Framework
The Video Toolbox framework (VideoToolbox.framework) includes direct
access to hardware video encoding and decoding.
but I can not find any tutorial documents for this right now
as I know it's a private framework before, and some people already using it in some JB apps
so does anyone can share a very simple tutorial code for this ?
Try this link: https://github.com/davidliu/VideoTimeLine (the video which I loaded seems to be broken, but you can get a feel how to use it).
Write in XCode: import VideoToolbox and CMVideoFormatDescriptionCreateFromH264ParameterSets and Cmd+click on it to display documentation :)
Take a look at this video from WWDC: https://developer.apple.com/videos/wwdc/2014/#513
Check out this code: https://github.com/manishganvir/iOS-h264Hw-Toolbox
Check out this code: https://github.com/McZonk/VideoToolboxPlus
You might also want to see a detailed description on how to decompress H264 using VideoToolbox: How to use VideoToolbox to decompress H.264 video stream
Hope that helps :)
Import the framework and look at the headers, they're all documented.
Apple also released a sample using VTDecompressionSession

Play RTSP stream on iOS with LIVE555

How to modify the example "openRTSP" of Live555 to display a RTSP stream in a iOS App ?
You can look at dropcam https://github.com
Personally I find it harder to use than some other frameworks including the ones we use, but the dropcam example should give yo what you need.
You can use MobileVLCKit which use live555 internally.
You can find more information here: https://stackoverflow.com/a/48340854/2003734

Samples/file extensions supported by iOS sampler

I'm writing an iOS app which can play MIDI and output its content using the AUSampler and AUGraph classes. I know for sure it supports files like Soundfont (.sf2) but this one seems to be quite antiquated.
Question: Are there any other files or sample types which this framework supports?
Thanks.
The AUSampler also supports DLS format (.dls) and AUpreset format (.aupreset)

iOS Video Player FFmpeg

So I want to make an app for the iPhone that will play live mms:// video streams.
I have look around, and everywhere says that I'll need FFmpeg in order to accomplish it. So I successfully compiled the FFmpeg libraries, but now
Do I have to convert the mms:// link to a .m3u8 link? Or I can just use apples AV Foundation Framework ?
Thanks!
You need libmms as well as the ffmpeg libs ,however as think the latest versions of ffmpeg has the code built in so you may not need libmms mms is just a streaming protocol so the actual format is likely some mpeg variant, mp4, h264.
Once you have that you extract the frames , and use ffmpeg avcodec_decode_video2 to decode to an avFrame. Just like any other video.
