6 years ago This question creates too much confusion When adding audio with the existing video it only write 15 seconds audio byte in the video. I tried alot to re understand the code but it is ok. Can you help me in this ?
I think the issue is only in the below code `if (!sawInputEOS) { inputBufIndex = audioEncoder.dequeueInputBuffer(10000); if (inputBufIndex >= 0) { ByteBuffer inputBuffer = audioInputBuffers[inputBufIndex]; inputBuffer.clear();
int bufferSize = inputBuffer.remaining();
if(bufferSize != extractAudioBuffer.length){
extractAudioBuffer = new byte[bufferSize];
mixAudioBuffer = new byte[bufferSize];
}
if(!readExtractAudioEOS){
extractAudioReadCount = fisExtractAudio.read(extractAudioBuffer);
if(extractAudioReadCount == -1){
readExtractAudioEOS = true;
}
}
if(!readMixAudioEOS){
mixAudioReadCount = fisMixAudio.read(mixAudioBuffer);
if(mixAudioReadCount == -1){
readMixAudioEOS = true;
}
}
if(readExtractAudioEOS && readMixAudioEOS){
audioEncoder.queueInputBuffer(inputBufIndex,0 , 0 , 0 , MediaCodec.BUFFER_FLAG_END_OF_STREAM);
sawInputEOS = true;
}else{
byte[] mixAudioBytes;
if(!readExtractAudioEOS && !readMixAudioEOS){
if(extractAudioReadCount == mixAudioReadCount){
twoAudioBytes[0] = extractAudioBuffer;
twoAudioBytes[1] = mixAudioBuffer;
}else if(extractAudioReadCount > mixAudioReadCount){
twoAudioBytes[0] = extractAudioBuffer;
Arrays.fill(mixAudioBuffer, mixAudioReadCount -1, bufferSize, (byte)0);
}else{
Arrays.fill(extractAudioBuffer, extractAudioReadCount -1, bufferSize, (byte)0);
}
mixAudioBytes = audioMixer.mixRawAudioBytes(twoAudioBytes);
if(mixAudioBytes == null){
DLog.e(TAG, "mix audio : null");
}
inputBuffer.put(mixAudioBytes);
rawAudioSize += mixAudioBytes.length;
audioEncoder.queueInputBuffer(inputBufIndex, 0, mixAudioBytes.length, audioTimeUs, 0);
}else if(!readExtractAudioEOS && readMixAudioEOS){
inputBuffer.put(extractAudioBuffer, 0, extractAudioReadCount);
rawAudioSize += extractAudioReadCount;
audioEncoder.queueInputBuffer(inputBufIndex, 0, extractAudioReadCount, audioTimeUs, 0);
}else{
inputBuffer.put(mixAudioBuffer, 0, mixAudioReadCount);
rawAudioSize += mixAudioReadCount;
audioEncoder.queueInputBuffer(inputBufIndex, 0, mixAudioReadCount, audioTimeUs, 0);
}
audioTimeUs = (long) (1000000 * (rawAudioSize / 2.0) / audioBytesPerSample);
}
}
}`
When two audios are mixed, the last audio duration is always 15 seconds while the first one is correct. What will be the problem?
