There's an unchecked access on a potentially null object in the method samplesAvailableToEncode(). If it happens that the number of samples added up to the point you call samplesAvailableToEncode() is a perfect multiple of the block-size used by the encoder, it should trigger the exception(or if no samples were ever added). I'll create a test case and verify this later tonight. Hopefully I will get the update posted tomorrow to...Preston LaceyFri, 22 Sep 2017 23:34:14 -0000https://sourceforge.net/p/javaflacencoder/discussion/1340251/thread/2a4ad5ed/?limit=50#131ahttps://sourceforge.net/p/javaflacencoder/discussion/1340251/thread/2a4ad5ed/?limit=25#7c0bVersion is 0.3.1 , 16-bit mono.

I'll check it out. In the meantime, can you tell me the conditions of the failure(which javaFlacEncoder version, encode settings used, is this still 16-bit mono as above?)Preston LaceyFri, 22 Sep 2017 19:20:05 -0000https://sourceforge.net/p/javaflacencoder/discussion/1340251/thread/2a4ad5ed/?limit=50#2bb8https://sourceforge.net/p/javaflacencoder/discussion/1340251/thread/2a4ad5ed/?limit=25#85b3Hi, sometimes while closing the stream and finalizing using flacEncoder.encodeSamples(flacEncoder.samplesAvailableToEncode(), true); This Fatal Exception is thrown java.lang.NullPointerException: Attempt to read from field 'int javaFlacEncoder.BlockEncodeRequest.count' on a null object reference at javaFlacEncoder.FLACEncoder.samplesAvailableToEncode(FLACEncoder.java:681) This happens sometimes and not all the times.

I had imported javaFlacEncoder source code and not the jar file. So, I deleted the source code and imported the jar file as a library. Before this, my code was failing everytime on all occassions but now it is encoding properly and producing good files that are seekable and have a known length. I will be waiting for the update though.Muhammad Moemin AliFri, 08 Sep 2017 00:12:29 -0000https://sourceforge.net/p/javaflacencoder/discussion/1340251/thread/2a4ad5ed/?limit=25#a030https://sourceforge.net/p/javaflacencoder/discussion/1340251/thread/2a4ad5ed/?limit=50#7407Interesting. The header for the #277 file is properly finalized, while the header for #388 is not. Does your code only occasionaly fail to produce a proper file now, or always fail? For example, did the run that verified the two values were equal also produce a good file, or a bad file? My point is I'm curious if something is only occasionally interrupting that code before it reaches the point of finalizing the header. I did check the library source though, and there is indeed a bug that might cause...Preston LaceyThu, 07 Sep 2017 22:34:57 -0000https://sourceforge.net/p/javaflacencoder/discussion/1340251/thread/2a4ad5ed/?limit=50#7407https://sourceforge.net/p/javaflacencoder/discussion/1340251/thread/2a4ad5ed/?limit=25#0a79I just checked the value returned by '"flacEncoder.samplesAvailableToEncode()" and "flacEncoder.encodeSamples(flacEncoder.samplesAvailableToEncode(), true);" are the same. I check again the value of '"flacEncoder.samplesAvailableToEncode()" and it is equal to 0. I am using (int buffer.length) to give sample count parameter and not numRead.

It sounds like the FLAC stream is not being finalized by the line, "flacEncoder.encodeSamples(flacEncoder.samplesAvailableToEncode(), true)" When the flac stream is finalized, various details needed for seeking(including length of stream and min/max encoded frame size) are written to the front of the stream if possible(this step will be ignored if the stream isn't seekable, but yours should be since you're writing to a file).

Some media players are unable to play the recording and the others that play do not display duration and provide seek options. Java code and the recording is attached.

Information about the encoded data(md5-hash, length, number of frames, etc) is kept while encoding, and this information is written out to the header space of the FLAC stream when the stream is closed. Currently, there is no method of restoring the encoder state necessary to write a proper header to the existing stream if appending new data.Preston LaceyFri, 11 Aug 2017 16:27:40 -0000https://sourceforge.net/p/javaflacencoder/discussion/1340251/thread/2a4ad5ed/?limit=50#7673https://sourceforge.net/p/javaflacencoder/discussion/1340251/thread/2a4ad5ed/?limit=25#b81bI have another question, how can I resume recording at the end of a previously saved flac file. When I try to add encoded data at the end of previously saved flac file, the recording resumes but there is an audible gap in between when the last recording was stopped and then resumed. What is the correct way to do this in javaFlacEncoder?

I can't be certain without more information on your source format and how you're reading them from the AudioRecord instance, but It looks like your problem will be with the source format conversion to int. If you're reading 16-bit PCM from the AudioRecord object, make sure you're reading those into a short[] and not a byte[] https://developer.android.com/reference/android/media/AudioRecord.html#read(short[],%20int,%20int) If you use a byte[] for 16-bit(which is deprecated but should work),...Preston LaceyWed, 02 Aug 2017 08:38:16 -0000https://sourceforge.net/p/javaflacencoder/discussion/1340251/thread/2a4ad5ed/?limit=50#0c31https://sourceforge.net/p/javaflacencoder/discussion/1340251/thread/2a4ad5ed/?limit=25#692dHi, I am using android to capture audio from phone's microphone via android's AudioRecord class.
