Play streaming video on libVLC iOS

[Isleo]

Hi forum,

I am working on an iOS application that play a streaming video from a Mobotix camera. They use MxPEG format. I tried MobileVLCKit 2.2.2 and the unstable version 3.0.0a10 with Cocoapods. However, with version 2.2.2. I can hear audio and with 3.0.0 just see a frame. This is the code, in summary:

Code: Select all

_mediaplayer = [[VLCMediaPlayer alloc] init]; _mediaplayer.delegate = self; _mediaplayer.drawable = self.movieView; NSArray *options = @[@"-vvv",@"--avformat-format=mxg"]; _mediaplayer = [_mediaplayer initWithOptions:options]; _mediaplayer.media = [VLCMedia mediaWithURL:[NSURL URLWithString:@"http://192.168.1.23/control/faststream.jpg?source=MxPEG"]];

Furthermore, I tried a single video downloading it from a server and it works. I do not know if it a problem of the format or the streaming.

I would appreciate it if you could suggest me other way to do it or the solution itself.

Thanks you in advance,

Isleo.

Can you dump and provide a sample stream?

Hi,

There are some public cameras on the Internet. You can try this one: http://86.125.43.4/control/faststream.jpg?stream=MxPEG. If you want to watch the output (it just frames, no audio), you can go to http://86.125.43.4 on you browser.

Thanks you,

Isleo.
