video problem to playing on android phone
Posted: 28 Feb 2013 03:12
I tried to build a streaming server on Windows to receive multimedia data from **.m3u8 on the network and then stream it out with rtsp.
The browser on android phone played with video and audio if I did it with VLC.
But the browser played with only audio and no video (black screen) if I did it with demo code of libvlc from wiki.
I don't know the difference between the two mode.
Demo code is as follows:
I think problem comes from the variable options[] in the code which is based on the demo, the document to vlc command and
vlc software. Streaming with vlc software will generate a stream output string on the dialog "option setup".
I tried a lot of commands in the options[] but no result.
Anyone can help me? Thanks in advance.
