Stream RTSP without Android Surface
Posted: 08 Apr 2015 19:02
Is it possible to access a stream without attaching it to a surface? So far I have only been met with errors. I spent about a week trying to enable the snapshot functionality (which finally works!), but I would really like to be able to take a picture in the background without viewing the stream.
So far anytime I try to initialize a LibVLC instance without attaching to a surface my stream loads and buffers to 100% and then I get the same two errors:
04-08 12:56:40.699: D/VLC(15203): live555 demux: tk->rtpSource->hasBeenSynchronizedUsingRTCP()
04-08 12:56:40.699: E/VLC(15203): core input: ES_OUT_RESET_PCR called
These are the relevant log entries:
I suspect I have to explicitly disable to video output, but I don't know where or how I would do that.
