FFserver : cannot connect via rtsp
27 avril 2016, par newfoundstoryso im currrently trying to stream my windows desktop using ffmpeg into a raspberry pi running ffserver.
The client software im using needs to use RTSP, however i cannot connect to the stream no matter what i try.
I even used VLC in the messages it just says it cannot connect to the stream.
Any help would be greatly appreciated !
Im attempting to access the stream with rtsp :// 169.254.70.227 :8544/test.flv, as soon as i do it stops the ffmpeg feedFFserver conf

dashjs can't find initialization segment on manifest.mpd
30 avril 2016, par Abelardo MendozaI am following this tutorial to stream a WebM. I have no issues running the ffmpeg commands to generate the videos/audio/manifest files but when I try to run it locally, there’s no video or audio at all and dashjs floods the console with :
Searching for initialization.
Start searching for initialization.
Perform init search: http://localhost:8080/video_1280x720_500k.webm
Perform SIDX load: http://localhost:8080/video_640x360_750k.webm
Perform SIDX load: http://localhost:8080/video_1280x720_500k.webmWriting that to console until I stop the server. I have tried using other mpd files such as this, which is used on the dashjs quickstart and it plays the video without any problems.
I used this guide to install the latest version of ffmpeg on Ubuntu 14.04 LTS :

Edit :
Like Will Law mentioned, using the Shaka Player worked without any issues with my current manifest. Hope this helps anyone else.
