I want to stream YouTube video inside an Android application using VideoView.
Everything seems to be fine, playback starts for specified RTSP URL, but the quality of the video is really really poor.
Does anyone know how to get RTSP URL with better (HD) quality?
It seems that JSON object does contain two urls for RSTP locations, but both are in the same very low quality.
I know it is not strictly programming question, but maybe anyone had the same problem?
Thanks.
Bartek.
To make High quality, put &fmt=18 or &fmt=22 in front of link. Source.

I can load a video from the web. All works fine.
However, when a network connection is slow the video is buffering. So I want to set the quality of video while, streaming it automatically or manually.
I am blank about this.
If I am not mistaken, VideoView only plays the video. Here is the documentation on it, doesn't seem to have that option at all.
I'd suggest you use the youtube API instead if you can.
Using Picasso I was able to download and display my images very quickly in my Android app. Now i want to stream my videos from my S3 server and play them through my app faster than my code here:
try {
MediaController VideoController = new MediaController(VideoPlayerActivity.this);//Creates a media controller to this activity.
VideoController.setAnchorView(AdVideoView);//Adds the media controller to the video view.
Uri video = Uri.parse(VideoURL);//Creates a Uri to hold the URL of the video.
AdVideoView.setMediaController(VideoController);//Add the media controller to the video view.
AdVideoView.setVideoURI(video);//Make the video view play from the Uri.
} catch(Exception e) {
Log.e("Video Stream Error", e.getMessage());//Sets the message for the log.
e.printStackTrace();//Displays the error in the stack trace.
e.notify();
}
Is there a faster way to display videos through a GitHub or better code?
Thanks in advance!
The things that usually slow down streamed video playback are server and network related rather than client side - unless you have a very slow or very busy device it is unlikely it won't be able to play the video back at the rate it is received over the network.
Taking this and assuming you are are seeing delays in your streamed videos, there are a couple of common things to look for.
First, mp4 videos in normal format have the metadata at the end of the video file which is not good for streaming. There is a technique called quickstart, which moves the metadata to the start which you definitely want to use. More info here:
http://multimedia.cx/eggs/improving-qt-faststart/
Secondly, network connections can obviously vary and slow networks make streaming high quality video files a problem. A technique called adaptive bit rate streaming (ABR) allows the client request lower quality video 'chunks' if the network quality is bad and then change to higher quality when it improves.
ABR also helps startup time as it allows you quickly start the video stream by using a lower quality level, and hence smaller size chunk, and then increase the quality as the video progresses. You can see this effect when you start up most online video services, such as Netflix, today (July 2016).
One thing to note is that video hosting and streaming is a specialist area so it is generally easier to leverage existing streaming technologies and services rather than to build them your self. Some good places to look to get a feel for open source solutions:
https://gstreamer.freedesktop.org

What is the best API for video streaming on Android? The Video is basically MPEG 2, kept on server, I want to stream to my Android phone which is having the decoder and our own player.
(decoding is happening on the phone itself).
The requirement is the delay should be as minimum as possible for smooth decoding and play back.
What about Gstreamer, is it a most efficient way?
Any suggestions?

Does anybody have any luck streaming a high quality video (over 1000kbps) to Android through RTSP?
We currently have low quality video streams (around 200kbps) that work wonderfully over 3G. Now we are trying to serve a high-quality stream for when the user has a faster connection. The high quality videos play smoothly in VLC, but the Android playback seems to drop frames and get blocky, even on a 4 megabit connection.
It seems like the YouTube app uses a plain HTTP download for their high quality videos. This works well and plays smoothly, but will not work for streaming live videos. Has anybody had luck streaming high quality videos to Android through RTSP?
The videos are encoded using H.264, 1500kbps, 24fps, and a 720x480 resolution. In the app, we are using a VideoView to play the videos. We are using Darwin Streaming Server, but we are open to other options if necessary.

Looking through Darwin some more today. So far, I am just logging the request and session information in a Darwin module.
The original Droid tries to use these settings: 3GPP-Adaptation:...size=131072;target-time=4000. Although that means it wants 4 seconds of buffer, 131Kb only holds about a second of playback at 1200kbps. I understand that 1200kbps is large, but it is necessary for a high quality video (minimal compression on 720x480).
I am trying to force the client to buffer more, but I haven't figured out how to do that yet. I'm just looking through the Darwin Streaming Server source and trying to figure out how they do things. Any Darwin experts out there?
Update 6/24/2011
As it turns out, using plain old HTTP for viewing videos on demand works well with no loss of quality. When we get to live streaming, we will have to look more into RTSP.
Well even if the network is able to transmit at that rate, you still need to decode it. What are you using for decoding? You will probably need to use a NEON accelerated video decoder so you can have a proper framerate, and a decent size buffer... the graphics processor is only as good as the bus that it is in... Also what are your encoding settings and resolution?
Edit: You are encoding those at much to high bitrate, half of that will do fine. Also you need to make sure where the issue lies. Is the mediaPlayer getting the data and failing to stream at a decent framerate, in that case you have to replace the MediaPlayer code with your own player. Is it's network issue then only solution is to lower the bitrate, 600Kbps would be just fine (or 500Kbps video, 128Kbps audio), it's 3x your 200k stream and on a screen this small, the difference is not noticeable.
I am using YouTube’s RTSP link to demo some capability to the client. Occasionally the mediaplayer fails to display any video (Blank screen). However I am able to hear the sound. Can someone help me understand what is going wrong?
Thanks for the help in advance
I dont know much about youtubes RTSP, but I have had similar problems with youtube not loading the video (but the sound is ok) when the playback quality is changed. I bet that is where your problem lies. I would make sure that you specify playback quality and everything and request that feed before loading it into your player if at all possible.
The Android Emulator doesn't work with streaming RTSP video. So I suggest you should test your streaming application (video) on real device.
Hope it is useful for you
