View Full Version : Phonon and buffer of local file

I'm trying to play a file with Phonon. Eveything works just fine if the file is "as-it-should-be", I mean, the file has the size that it should have (non-corrupt mp3 file for example.)
The problem comes when I try to play a file that I'm asynchronously downloading.
If I do
self.mediaObject.setCurrentSource(Phonon.MediaSour ce("Path"))
file will play just for a sec or so (the bytes that were downloding while the app was creating the controls, etc...
Is there any way that I can tell Phonon that this file isn't complete and that it should read/wait for buffer?

Nobody knows how to stream a local incomplete file?

I don't know If I understand correctly, but this is probably what You should try to use:
self.mediaObject.setCurrentSource(Phonon.MediaSour ce(QUrl("Path")))
Look also for Phonon::MediaSource::Type and try other types.
I personally use QUrl to play movies from HTTP, so I think it should handle.
If you want to download and play partially file that is currently downloaded, then this probably won't help You, although I can be wrong on this one.

I'm already using the QUrl("Path") thingy. But what I'm trying to do is to play a file that I'm downloading at the same time, so that would be:
1. Start downloading file via async
2. Start playing local file
3. Play while not EOF (pause when buffer needed)

AFAIK you could do something like this:
1. download file and store data in buffer
2. play buffer
MediaObject m;
QBuffer *someBuffer;
m.setCurrentSource(someBuffer);
3. save to file
Sorry but I can't help You more then this simply because I didn't used it before.

Thanks! Tomorrow morning I'll read docs about buffer and I'll try it out ;)

Hi,
I'm facing the same problem while playing audio. Did you find out the solution? If so then please share your knowledge.
Thanks in advance.
