I'm playing video on Android using media player via RTSP. The player takes about 12s to buffer before it starts playing. Anyone know how I can convince the player to buffer less? I have full control over the RTSP server and the SDP it returns.
As per usual, as soon as I decide I should ask a question I work out the answer. I have a line "b=AS:91" in my SDP. If I reduce the number the amount of buffering decreases - so b=AS:2 gives about 4 or 5s buffering.

I am developing an android app which plays a video from a server where I stored my video content. But it takes too much time to play a video, using 300-400 kb/s it takes almost 15-20 sec.
I want to know what facts are related to stream faster and how can I solve my problem.
It could be:
The video bitrate is too high for the connection speed
The player initial buffering is too safe
If you're saying your network is 300-400kbps, you probably want to try converting your video to an adaptive format like HLS or DASH, where the player will detect the user's bandwidth and download the best quality version that can start quickly.
From there it could be player configuration, adjusting the amount of buffered video the player waits for before starting playback. But beware, reducing initial buffering can cause rebuffering later in playback.
I want to restrict buffering after pausing a video in android. When I pause the video player, the video stops but buffering does not. It continues to consume data. I want to stop data to be consumed.
Thanks in advance.
With a standard mp4/webm, you can’t. It’s totally up the the browser. If you use fragmented mp4 and feed the buffer via MSE and Ajax, you can do whatever you want. But it’s a thousand time more work on your part.
You can't skip buffering it depends on the network
I need to stream rtsp-video from IP camera in local network to my android app. It's very easy to use VideoView and play it as url, or SurfaceView and play stream on it with native MediaPlayer. But when I stream that way - I've recieved a 6-second delay when my phone is buffering that video. As I read, there is no way to change buffer size of MediaPlayer. But I saw several apps that stream video from my camera in almost real-time. I've read a lot about this - cause I'm not the first one who encountered this problem - but didn't find any useful info.
Many thanks for any help!
I'm using vlc-android, it works well to play my cameras' rtsp links:

The delay is about 1 second.
I am trying to stream audio through a server. I have set up everything, and it's working fine with recording and playing back static audio, but when I am trying to stream an audio there is a delay on the playing side.
I did a Google search, but couldn't find the proper way of doing this. I am using AudioRecord & the Audiotrack Android media API for sending & receiving audio data. Can anybody tell me how to handle this delay?
I have added my code on GOOGLE GROUP to get clear picture.
I had tried in this way, holding 5 chunks of audio data in a buffer which comes through the server & playing back when it fills 5 chunks of data and again getting next 5 chunks of audio data and filling it like that it goes till 1024 bytes of data (it writes to the audiotrack & the play method is called).This too has a delay,any other solutions??
If you're really trying to do this unbuffered, make sure whatever playback tool you're using is trying to play it back without a buffer. You will be hard-pressed to not have a delay. Nothing on TV, radio, etc. is really 'live'--there is always some kind of delay. With internet streams, you're sending a large amount of data constantly. Even besides the time for it to travel, all this data has to be kept in a particular order and nobody wants choppy playback while the enduser's computer attempts playback. I've had flash players for major networks keep massive cache files on my computer while it's handling playback, but their players do not skip/wait to buffer/etc. (If you load up something and notice a few 100 MBs of extra memory being used, maybe even more during playback, that's what that is.)
You might be able to get away with a very small buffer (the standard in the past used to be 30-60 seconds and a lot of players still default to this) using VLC. I have been able to set its buffer very low but it is on incredibly low quality streams/videos. The big problem you have though I'd guess is your playback is setting the buffer and if your playback is set to 60 seconds buffer, it doesn't matter what you do serverside...the client end will wait until it has that much of a chunk and then begin playback.
Live streaming is not continuous in my application using NexPlayer. It takes around 10 secs of buffering. What I want is to have a large buffer initially but once streaming starts then buffering should happen in the background, and streaming will be going on meanwhile. Is this possible using async task? Has anyone worked on NexPlayer stream video? Please let me know, as it is very critical for my application.
