我不知道什么是timestampUs 40000 < lastTimestampUs 120000 for Video track请任何人帮忙
This is working in

最佳答案
尝试将提取逻辑重构为使用 videoExtractor.advance(); 作为 sawEOS 的条件
do {
videoBufferInfo.offset = offset;
videoBufferInfo.size = videoExtractor.readSampleData(videoBuf, offset);
videoBufferInfo.presentationTimeUs = videoExtractor.getSampleTime();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
videoBufferInfo.flags = MediaCodec.BUFFER_FLAG_KEY_FRAME;
} else {
videoBufferInfo.flags = MediaCodec.BUFFER_FLAG_SYNC_FRAME;
}
muxer.writeSampleData(videoTrack, videoBuf, videoBufferInfo);
} while (videoExtractor.advance());
