Library iOS video picker using AVCapturexxxx libraries

ifvideopicker's Issues

Can I output flv buffer with IFVideoPicker?

IFVideoEncoder *ve =
[IFVideoEncoder createH264VideoWithDimensions:dimensions
bitRate:500000
maxKeyFrame:200];

[videoPicker_ startCaptureWithEncoder:ve
audio:ae
captureBlock:^(NSArray *frames, NSData *buffer) {
// Captured MP4 frames are coming
NSLog(@"buffer: %d bytes, with %d frames", [buffer length], [frames count]);
} metaHeaderBlock:^(MP4Reader *reader) {}
// MP4 moov header coming
} failureBlock:^(NSError *error) {
// Failed to capture video / audio chunk
}];

In the captureBlock,buffer is mp4, now I want to convert mp4 to flv, so I can stream it to a rtmp server with rtmp-wrapper's help .
How can I do that? Thanks.

there are many encode failed error

MemoryLeak fix

Hey, I think this is an awesome project and I love what it does and how beautifully written it is! One small problem I have found in testing is that there is a memory leak. While it can be quite small leak at the rate (30 FPS and 44.1 Hz) that one could be capturing the audio and video frames it can become quite a big leak over time causing to a crash within the apps if videos are long enough. While i am no expert on the matter of memory management as I came in to IOS development after ARC was created it seems that the issues for the leaks is retaining the body object properties in both the FLVVideoTag and the FLVAudioTag objects. I changed
@Property (atomic, retain) NSData *body;
to
@Property (nonatomic) NSData *body;
In both those files. Once the change was in place the memory stayed at around the 10MB mark.

Thanks for your time.
