currently I'm working on an application that's supposed to download videos onto its internal storage (unfortunately they do NOT have a sd card) and simply play them. What I've tried so far is:
Standard VideoView, set the /data/data/.../file.mp4 as path - did not work. Use MediaPlayer with a SurfaceView, use path or file descriptor - did not work.
What I'm having here right now is a slightly modded version of the VideoView, which has the following changes:
if(mUri != null)
{
mMediaPlayer.setDataSource(mContext, mUri);
}
else
{
mMediaPlayer.setDataSource(mFd);
}
Also a setFD method allowing me to set my File Descriptor. This is way easier and cleaner - imo - than putting the whole MediaPlayer/SurfaceView into my activity. The problem is the following:
The file in the internal storage is created like this:
FileInputStream fis = openFileInput(Downloader.TMP_FILENAME);
FileOutputStream fos = openFileOutput(Downloader.FILENAME
+ ext, Context.MODE_WORLD_READABLE);
byte[] buf = new byte[2048];
while (fis.read(buf) > 0) {
fos.write(buf);
}
fis.close();
fos.close();
deleteFile(Downloader.TMP_FILENAME);
Log.d(TAG, "Replacement done!");
Basically it's reading a temporary file (as I don't want to overwrite the currently played one.. but that doesn't really matter) and writing it (after onCompletion) into the new file, afterwards deleting the temporary file.
I've tested it on 3 different Android versions and devices so far: - Tablet with Android 2.2 - Nexus 7 with Android 4.2 - HTC Sensation with Android 4.1.2
It simply did not work. It plays lets say the first 100ms of the video incl. sound then a popup pops up and logcat is telling me:
12-19 14:33:48.074: W/MediaPlayer(5560): info/warning (3, 0)
12-19 14:33:48.074: I/MediaPlayer(5560): Info (3,0)
12-19 14:33:48.394: E/MediaPlayer(5560): error (1, -1007)
12-19 14:33:48.394: E/MediaPlayer(5560): Error (1,-1007)
But I really have no idea what this is supposed to mean. I've searched for it in the whole internet, all I found was "use WORLD_READABLE, it will solve the problem!" or "just use the file descriptor, seems to not care about permissions!". But for me, it does not work.
I'd really appreciate any help.
EDIT:
FileInputStream fid = new FileInputStream((getFilesDir() + "/"
+ Downloader.FILENAME + ext)));
mVideoView.setVideoFD(fid.getFD());
This is how I add the File Descriptor to the MediaPlayer.
After reencoding the file, this is what I get:
12-19 15:06:45.664: E/MediaPlayer(7616): Unable to to create media player
12-19 15:06:45.664: W/System.err(7616): java.io.IOException: setDataSourceFD failed.: status=0x80000000

12-19 15:06:45.664: W/System.err(7616): at android.media.MediaPlayer.setDataSource(MediaPlayer.java:976)
This is how I download it from my webserver:
Log.i(TAG, "Opening remote connection to " + mFile.getHost()
+ mFile.getPath());
URLConnection c = mFile.openConnection();
c.connect();
final long lastModified = c.getLastModified();
final String mExtension;
if (c.getHeaderField("Content-Disposition") != null) {
final String mFilename = c
.getHeaderField("Content-Disposition").split("=")[1];
Log.i("Downloader", "Filename is " + mFilename
+ ", split length is " + mFilename.split("\\.").length);
mExtension = mFilename.split("\\.")[mFilename
.split("\\.").length - 1];
} else {
mExtension = "mp4";
}
InputStream is = c.getInputStream();
Log.i(TAG, "Creating temporary local file");
// create local temporary file
FileOutputStream fos = mContext.openFileOutput(TMP_FILENAME,
Context.MODE_WORLD_READABLE);
// start reading
byte[] buf = new byte[BUFFER_SIZE];
int bytesRead = 0;
int curRead = 0;
Log.i(TAG, "Starting download.. to " + TMP_FILENAME);
if (mDownloadChangeListener != null)
mDownloadChangeListener.onDownloadStart();
while ((curRead = is.read(buf)) > -1) {
fos.write(buf);
bytesRead += curRead;
}
Log.i(TAG, "Read " + bytesRead + " bytes in total.");
Log.i(TAG, "Download finished!");
// end of stream, tell app to rename file.
if (mDownloadChangeListener != null)
mDownloadChangeListener.onDownloadFinished(TMP_FILENAME,
mExtension);
is.close();
fos.close();
After downloading it, on the onDownloadFinished listener, I execute the following code:
FileInputStream fis = openFileInput(Downloader.TMP_FILENAME);
FileOutputStream fos = openFileOutput(Downloader.FILENAME
+ ext, Context.MODE_WORLD_WRITEABLE);
byte[] buf = new byte[2048];
while (fis.read(buf) > 0) {
fos.write(buf);
}
fis.close();
fos.close();
deleteFile(Downloader.TMP_FILENAME);
Log.d(TAG, "Replacement done!");
Any ideas what could possibly go wrong? My only other idea would be that it's because of the internal storage-thing.. but the error message says something else?
Found the solution. Every way I've tested worked probably, because all errors I received came from "wrong downloaded media files"...
while((curRead = in.read(buf)) {
out.write(buf);
}
Was simply missing a ",0 ,curRead" - all working now. It's obviously because read() can always return less than BUFFER_SIZE and then writes 0-bytes into the rest or something...
Thanks!
