Android :: Stagefright Mediaextractor - How To Detect Interlaced Streams In Video Files
Sep 7, 2010
Is it possible to detect scan type (progressive or interlaced) of a video file in stagefright?
I see below listed fields are query-able with metadata of file through stagefright, but not scan-type which i guess is avaiable in MP4 file header. Any hint on how to detect scan-type of video file at Stagefright player driver? Or is it available in opencore?

I just switched from WebOS so I'm quite a noob to Android. Anyways, I bought a new Samsung Galaxy Nexus with Android 4.4.
Now to my issue: I like to watch video streams. The problem is, that the display will turn automatically off.
Solutions:
1. Play a stream with a video player - how can I do this?
2. Change settings so the display will not switch off on a stream, but will turn off when idle - is this even possible?
3. Turn off "turn off display when idle" setting - but I don't like this one.

I'm trying to detect when new videos are taken. I'd succeeded to detect new photo using the intent filter action "com.android.camera.NEW_PICTURE" in a receiver but I don't know how I can detect new videos.

Can anybody advice what is the recommended directory to store files generated by your application: audio files, video files or some images.
If the phone contains SD card, it is clear that files should be saved there, but if there is no any external storage. where would you recommend to save to?

I am using a VideoView to display a video. I am using setOnPreparedListener and setOnCompletionListener to do stuff before and after the video starts and ends.
I was wondering how I could go about detecting some point of time in the video. For eg, say I want to write log to a file when the video has played for 10s. How can I detect the 10s mark?

I have a problem on my galaxy note II GT-N7100, running Paranoid Android 4.0 beta, android 4.4.1
Ever since I've upgraded to KitKat, some of my apps don't detect data on external micro SD card. Most noticeably quick office, the bards tale. As most of my files are stored on micro SD this is very annoying. I can access those files using es file explorer but it would be better if apps could detect them as well. My external SD card pathway should be mnt/media_rw/sdcard1 but that's empty and I get invalid file path error.
I can access the ext sd by storage/sdcard01 though. I've tried to format my ext SD, edit platform.xls etc but no solution. So any clue how to make quockoffice access documents on external micro sd?

I am developing a multiplayer game on android. I am having a Java server and android client. The android client issues multiple requests and receives responses from the server. However the performance is not smooth. At times the data received at the Java server is not what I send from android. It is junk or zeroes. However, some times, data is correctly received.
I was wondering is there any data loss in between and why? I am using java.net on both ends. Please let me know if anybody was facing a similar problem anytime during android development.

I am developing android a few days now and startet to write an application that gets a file from a server to display the content.
I have this code here
CODE:.....
The strange thing is that nothing is shown in the TextField. If I test the code in a standard java project the printing of the data (with println) works correctly in the console. But when i run it on the android vmachine nothing is shown. I got no more ideas left to proof the code. Anyone has some advices for a newcomer?

I haven't done any work with the Android or iOS platforms, but I have recently been pitched a project and I'm trying to see if it is even feasible.
Is there currently API hooks in the iOS and Android platforms for accessing / manipulating the voice / data streams? What I would like to do is encrypt all outgoing steams and decrypt all incoming streams before they reach and other processes that need that data.
I would assume that because the Android platform is open source one should be able to do this, it just may have to be hacked together. I'm more worried about iOS.

I have a problem streaming live video files. When I stream a file say of duration 5 minutes, it stops after streaming 2 to 3 minutes and enters in to endless buffering state. The VideoViews's OnBufferingListener is endlessly executed, however it shows that the buffering is not progressing anymore : MediaPlayer's buffer says it has buffered for example 90% whereas when I call videoView.getBufferPercentage(), I get something very low, like 1% or 5% ... After a while in the buffering state, the application crashes. It seems like the buffering is taking all the memory.

I am working on an Android application which is supposed to play videos over HTTP on Android devices. Before we setup a server to host the video files just wanted a few things clarified: As per the developer documentation, Android supports .mp4 and .3gp container formats for video.
The audio-video codec used for our media files is H.263(video) and AAC LC (Audio). I did a little experiment and passed URL of one of the video files to the MediaPlayer class and got the following error: Command PLAYER_INIT completed with an error or info PVMFErrContentInvalidForProgressivePlayback.
From the docs, I came to know that for progressive playback, the video's index (e.g moov atom) should be at the start of the file. How do we make our videos Android-ready? What are the different considerations that we need to make?

AOR by leadapps did this well. But when I upgraded my moment to eclair 2.1, I could no longer find the app. This is one reason the android experience has been a let down for me; I'm no bagger or birther, but damn...this is one socialist OS. Anyway, what have you used to hear streams of .aac's?

Just an FYI - on 2.1 Twit Live stream was dead, now it is alive and well - at least for me the 400kpbs stream seems rock solid.
Sorry if you aren't into Twit, but I watch that livestream pretty regularly.
