我想要这样一个输出视频,其输出的音频是使用ffmpeg -filter_complex机制创建的,
/usr/local/Cellar/ffmpeg/3.2.2/bin/ffmpeg
-i /uploads/videos/1487684390-lg9htt0RW2.mov
-i /uploads/audios/1487664761-SCPbo6Tkac.mp3
-filter_complex "
[0:a]atrim=0:8.70824980736,asetpts=PTS-STARTPTS[aud1];
[1:a]atrim=0:12.9567301273,asetpts=PTS-STARTPTS[aud2];
[0:a]volume=0.3,atrim=start=8.70824980736:21.6649799347,asetpts=PTS-STARTPTS[slow_aud];
[aud2][slow_aud] amerge=inputs=2[a_merged];
[0:a]atrim=start=21.6649799347:31.6410098076 [remaining_audio];
[aud1][a_merged][remaining_audio]concat=n=3:v=0:a=1[aout]"
-map 0:v -map "[aout]" -c:v copy -acodec mp3
/uploads/output/1487684390-lg9htt0RW2.mov
根据UTC时间戳记录录制的原始音频视频基于UTC时间戳录制的原始视频
13:00-------- Original Event Audio -------- 13:20
12:50------------- Event Video Recorded --------------13:30
这是我的要求
因此输出视频的音频应包含
通过以上命令获得的内容
答案 0 :(得分:1)
您无法重置剩余音频的时间戳,就像concat过滤器所需要的那样。所以,它应该是
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="maintext">
<h2> Main text goes here...</h2>
</div>
<div id="boxes">
<div id="dialog" class="window">
<div id="san">
<section>
<select id="Rank" class="cs-select cs-skin-elastic">
<option value="" disabled selected>Choose Language</option>
<option value="English" data-class="flag-english">English</option>
<option value="Arabic" data-class="flag-arabic">Arabic</option>
<option value="French" data-class="flag-french">French</option>
</select>
</section>
</div>
</div>
<div style="width: 2478px; font-size: 32pt; color: white; height: 1202px; display: none; opacity: 0.4;" id="mask"></div>
</div>
<div class="container">
<div class="English">
<select class="second-level-select">
<option value="">-Select Your Country-</option>
<option value="USA">Usa</option>
<option value="India">India</option>
</select>
</div>
<div class="Arabic">
<select class="second-level-select">
<option value="">-Select Your Country-</option>
<option value="UAE">UAE</option>
<option value="Kuwait">Kuwait</option>
</select>
</div>
</div>
实现相同结果的更简单方法是
[0:a]atrim=start=21.6649799347:31.6410098076,asetpts=PTS-STARTPTS[remaining_audio];
