Gstreamer:将Matroska视频转码为mp4 [英] Gstreamer : transcoding Matroska video to mp4

问题描述

我们正在使用的硬件不支持播放mkv文件. 因此，我需要将Matroska(mkv)视频文件转码为mp4视频文件.

The hardware on which we are working on doesnt support playing of mkv files. So i'm required to transcode Matroska (mkv) video filea to mp4 video file.

从网上关于转码的资料中了解到，我需要执行以下操作:

As I have understood from the material available online on transcoding,I'm required to do the following :

1. 使用 matroskademux 元素分离出mkv文件的不同流.
2. 使用可用的mkv解码器将音频和视频流解码为原始格式，并且
   将此数据提供给mp4 Muxer元素，然后重新编码为所需格式.

1. separate out different streams of mkv file using matroskademux element.
2. decode the audio and Video streams into raw format using available mkv decoder and
   supply this data to the mp4 Muxer element and re-encode to required format.

有人可以告诉我是否采用正确的方法吗? 关于此的任何信息/链接都将非常有帮助.

Could anyone please tell me if I applying right approach? Any information/link on this would be very helpful.

推荐答案

根据Matroska文件中的内容，您可能根本不需要解码，只需重新混合即可.

Depending on what is in the Matroska file you might not need to decode it at all, just remux.

我假设视频是H264，所以只需重新混合即可. 以下是用于gst-launch用于使用h264和mp3重新混合文件的示例管道.

I assume the video for instance is H264, so just remux that. Below is an example pipeline for gst-launch for remuxing a file with h264 and mp3.

gst-launch-0.10 -v filesrc location=$file \
! matroskademux name="demux" demux. ! h264parse ! queue \
! mp4mux name=mux ! filesink location=$file._out.mp4 demux. \
! mp3parse ! queue ! mux.`
