I want to force the Evo 3D Mediaplayer to show any videos as 3D. The problem is that the HTC Evo 3D is said to be becoming 3D with FPA SEI flag on mp4 file. Is there any way to introduce that flag programmatically?
I want to find where it is overridden and turn it off by hand. I tried to figure out where it is read in the Android media player( http://www.netmite.com/android/mydroid/frameworks/base/media/java/android/media/MediaPlayer.java ); however, I couldn't found. My guess is the HTC is implemented another media player which looks for SEI FPA flag in mp4 header.
Is there anybody who can help me with this situation?
Your best bet is to upload your 3D SBS video to Youtube, and then ask Youtube to change it to 3D. When it's done, wait for 20 minutes and then view your video in 3D on Youtube from your Evo 3D. If it works, then just go ahead and download it from the Youtube website using an internet download manager. Now, if you put that video on your SD card, it should play directly in 3D mode.

Has anyone been able to successfully play a HD video using Android Things on a Raspberry Pi? If so was there anything special you had to do to get it to work? If not does any one know why it isn't working?
I made a simple video player that plays a local video from disk. The app runs fine on a phone but with android things maximum frames are getting dropped.
I am using ExoPlayer for the video playback and the same issue is observed when Media Player is used.Hardware acceleration is also enabled in the manifest file.
When i run my application on the tablet(android) and hit the pause button it pauses the screen of the video but the video will jump a head how ever many seconds the pause when i un-pause the video. So if i start the video and then click pause and walk away i can come back and un-pause the video and it well jump right to the end.
The code i am using is ns.togglePause(); This same code works on the desktop and works with .flv and .f4v but will not work when i am using a mp4 on the tablet.
Has anyone seen this before or know why it would do something like this?
i am using flashdevelop to debug the application.
I found out that my problem is caused by encoding. This helped me solve my problem.I found this on adobes forms.
Video encoding is very important.
For example, use baseline profile level 3.1 for H264 for mobile
(and not High profile level 4.1 recommended for desktop).
For more information, see the MAX session of Fabio Sonnati:
"Encoding for Performance on Multiple Devices"
And if you have an Android phone/tablet, there is my AIR application
to watch Adobe MAX 2011 videos :

Search "Sonnati" for this session's video.
(For info, i use a video player based on OSMF 1.6)

I just want to know if I can see several videos at once from the network using rtsp? I'm trying to do an android app similar to video surveillance and I need to see several videos at the some time in the screen, I tried to use it with MediaPlayer and after that with VideoView, but in the both cases sometimes the videos appear, sometimes give me an error that can not play one or more videos...What can I do to put it to work well?
What Cruceo said is correct. It's better to mux (FFmpeg is really great) all streams in one stream with a incredible resolution with a low bitrate & framerate. Then create a program to display it and make zoom in when you select a viewpoint.
A other option would be to change the video streams into jpg files. This way is allot easier because you can use your web browser to display it. With your web browser you can make use of JavaScript (ProcessingJS is very easy and good at this) to make a image viewer with allot of functionality.
In my application I need to provide the user with a preview on a progressive download (video file).
In order to achieve this, I'm using VideoView component to show the content of the video (.mp4, .3gpp) which is being downloaded.
The problem is that I can't access remote media via http:// or rtsp:// protocol, so I'm forced to use VideoView.setVideoPath to play local copy of the video while downloading.
Unfortunately it seems like on Android devices that can't use StageFright framework (so OpenCore and some Tegra2-based devices in my experience), the VideoView can't handle progressive download correctly: it can play only the portion of the video recognized during the component initialization.
So to be clear: if the user press "play" when only 5% of the video has been downloaded, VideoView will show only that 5% of video, no matter if more video content ha been downloaded in the meantime.
In my experience this issue doesn't affect devices using StageFright framework (e.g.: Nexus One 2.2, Nexus One 2.3.4).
Can anyone point me to a possible solution ?
Thanks in advance
If you are trying to play .h264, You need to move the MOV atoms to the front of the file. These tell the codec the length of the movie among other things.

VideoView is a ready to use class in Android Application Framework for video playback use case. It internally uses MediaPlayer class to achieve playback. MediaPlayer uses media frameworks available internally based on certain criteria like file format , origin of content etc.
So the limitation is from underlying framework and not VideoView. If you are still suspecting VideoView then write your own video player activity using media player. You will see the same result.
Also not all versions of Android (read as stagefright) support progressive download.
May be you can use DownloadManager class for downloading content from http server and provide the path to media player / video view for a quick preview.

I've coded up apps using VideoView and MediaPlayer and both had the same behavior. I'm currently using the code example here. The problem I'm having is that the video doesn't play back continuously. The slider in the MediaController is moving but the picture doesn't change. If I manually drag the slider the picture will change like it should.
I'm using an mp4 file loaded from the sdcard with a SDK 2.3.1 emulator device.
Any help is appreciated.
You usually cannot test video playback applications on the Android emulator, as it is too slow, except on very powerful host PCs. Please test video playback applications on an Android device.
