Gstreamer结束流 [英] Gstreamer end of stream

问题描述

我有两个视频流.视频和音频.其中之一可以是空的，即一开始是流结束. 但是

I have two streams. Video and audio. One of them can be empty, i.e. end-of-stream at start. But

在音频eos之后馈送视频没有任何输出.管道看起来像

Feeding video after audio eos makes no output. Pipe looks like

appsrc name=audioin | queue | capsfilter | alawdec | .mp4mux
appsrc name=videoin | queue | capsfilter | h264parse | .mp4mux
mp4mux | filesink

如何使多路复用器失效?

How make mux fail safe?

我添加了adder元素和audiotestsrc wave=silence，但是随后我在音频输入上发送了eos-视频输入和静音停止了

I added adder element and audiotestsrc wave=silence but then i send eos on audioin - videoin and silence stops

推荐答案

我是混合错误，flvmux可行.没有音频的视频没有PTS.

I was muxer bug, flvmux works. Video without audio has no PTS.
