我正在运行 melt 命令来编辑一些视频剪辑和音频剪辑。我在这里给出了我用来获取编辑视频的命令,但遇到比特率问题以及执行此命令需要太多时间。我有最新版本的 MLT(0.8.0) 并安装在 UBUNTU 中。命令如下:
melt avformat:http://54.241.13.15/cdn/images/1/1576/17s_331.flv out=425.4 -move in=0 out=425.4 out=425.4 -track avformat:http://54.241.13.15/cdn/image/1/1584 /180_834.flv out=336.9 -move in=0 out=336.9 out=336.9 -filter chroma key=#00ff00 variance=0.38 -transition composite geometry="42%,24%,50%,50%" halign=left valign=top a_track=0 b_track=1 -track -blank 61.2 a_track=0 b_track=2 avformat:http://54.241.13.15/cdn/images/1/1583/17z_786.flv out=398.1 -move in=0 out=336.9 out=398.1 -filter chroma key=#00FF00 variance=0.38 -transition composite geometry="14%,10%,38%,43%" halign=left valign=top a_track=0 b_track=2 -track avformat:http://54.241.13.15/cdn/images/1/1532/16k_177.mp3 out=756.9 -move in=0 out=756.9 out=756.9 composite.progressive=1 producer.align=center -consumer avformat:/var/www/enclood/app/web/files/test-temp1.webm s=320x240 fullscreen=1 rescale=bilinear frequency=22050 b=512k ab=128k -profile square_ntsc vcodec=libtheora b=1000k ab=512k f=ogg | oggfwd 127.0.0.1 8000 manu123 /live.ogg
输出花费太多时间并出现以下问题:
[flv @ 0xb9643940] 从比特率估计持续时间,这可能不准确 [flv @ 0xb9643940] 从比特率估计持续时间,这可能不准确 [mp3 @ 0xb0998cc0] 达到 max_analyze_duration
如何解决这个问题?
请回复我。提前致谢!
