Thank for reply But i think error in video encoder.

I debug in this function

fun drainEncoder(data: ByteArray): Int { var length = 0 val encoderOutputBuffers = mEncoder?.outputBuffers ?: return 0 val status = mEncoder?.dequeueOutputBuffer(mBufferInfo, 10000) ?: return 0 if (status >= 0) { val encodeData = encoderOutputBuffers[status] // config data sps/pps if ((mBufferInfo.flags and MediaCodec.BUFFER_FLAG_CODECCONFIG) != 0) { // The codec config data was pulled out when we got the // INFO_OUTPUT_FORMAT_CHANGED status. The MediaMuxer won't // accept // a single big blob -- it wants separate csd-0/csd-1 chunks -- // so simply saving this off won't work. if (mBufferInfo.size != 0) { encodeData.position(mBufferInfo.offset) encodeData.limit(mBufferInfo.offset + mBufferInfo.size) length = mBufferInfo.size encodeData.get(data, 0, length) mBufferInfo.size = 0 } } Log.e("mBufferInfo", "mBufferInfo.presentationTimeUs " + mBufferInfo.presentationTimeUs) Log.e("mBufferInfo", "mLastPresentationTimeUs " + mLastPresentationTimeUs) if (mBufferInfo.presentationTimeUs >= mLastPresentationTimeUs) { if (mBufferInfo.size != 0) { encodeData.position(mBufferInfo.offset) encodeData.limit(mBufferInfo.offset + mBufferInfo.size) mLastPresentationTimeUs = mBufferInfo.presentationTimeUs length = mBufferInfo.size encodeData.get(data, 0, mBufferInfo.size) val type = (data[4] and 0x1F).toInt() if (type == SPS) { // 某些手机I帧前面会附带上SPS和PPS，剥离掉SPS和PPS，仅使用I帧 val idrFrame = splitIDRFrame(data) System.arraycopy(idrFrame, 0, data, 0, idrFrame.size) length = idrFrame.size } } } mEncoder?.releaseOutputBuffer(status, false) if ((mBufferInfo.flags and MediaCodec.BUFFER_FLAG_END_OF_STREAM) != 0) { // end of stream, break encode data return -1 } } return length }

@wlanjie you can see log

samsung j410f have output mp4 only first frame

You can help me your solution

[wlanjie]

Your first timestamp 231965691750, when the following timestamp is less than the previous time, it will not be able to decode

[tuananhdtu]

why samsung j410f return first timestamp 231965691750? you can explain it?

[tuananhdtu]

in class MediaCodecSurfaceEncoder method onStart() you can set this line is bold, the error is fix

mEncoder = MediaCodec.createEncoderByType(MIME_TYPE) mEncoder?.configure(format, null, null, MediaCodec.CONFIGURE_FLAG_ENCODE) mInputSurface = mEncoder?.createInputSurface() if (SDK_INT >= 23 ) { mInputSurface?.let { mEncoder?.setOutputSurface(it) } } mEncoder?.start()
