我正在玩gstreamer命令行界面，并在从PNG图像创建mp4视频文件时卡住了。你们能帮忙解决这个问题吗？
我使用以下命令从摄像机创建了PNG图像：
gst-launch-1.0.exe -v ksvideosrc！排队！解码器！视频转换！ pngenc！ multifilesink location =“ frame％05d.png”
我可以使用以下命令播放pPNG图像：
gst-launch-1.0 -v multifilesrc location =“ frame％05d.png” index = 0！ pngdec！ glimagesink
但是在从PNG图像创建mp4视频时，我从管道中收到了EOS：

答案 0 :(得分：1)
要从png中创建mp4，可以使用以下管道：
gst-launch-1.0 -e multifilesrc location =“ frame％05d.png”
caps =“ image / png，framerate = 30/1”！ pngdec！视频转换！排队！ x264enc！排队！ mp4mux！ filesink location = image.mp4
注意：
