ffmpeg旋转图像以馈送ffserver

问题描述

使用ffmpeg，我从重复读取的图像向ffserver提供提要.我使用以下说明

With ffmpeg I am providing a feed to ffserver from an image repeatedly read.I use the following instruction

ffmpeg -v debug -loop 1 -f image2 -i http://IP_ADDRESS/image.jpg -c:v libx264 http://FFSERVER_IP_ADDRESS:8090/feed.ffm

通过这种方式，我可以从服务器获取流，但是我需要旋转结果流.

In this way I can get the stream from the server but I need to rotate the resulting stream.

我以这种方式尝试了-vf transpose = 1选项

I tried with the -vf transpose=1 option in this way

ffmpeg -v debug -loop 1 -f image2 -i http://IP_ADDRESS/image.jpg -c:v libx264 -vf transpose=1 http://FFSERVER_IP_ADDRESS:8090/feed.ffm

但什么也没发生.

我的ffserver.conf

my ffserver.conf

HTTPPort 8090
RTSPPort 7654
HTTPBindAddress 0.0.0.0
MaxHTTPConnections 2000
MaxClients 1000
MaxBandwidth 1000
CustomLog -

<Feed feed.ffm>
File path_to_file/feed.ffm
FileMaxSize 10000K
ACL allow 192.168.1.0 192.168.1.255
</Feed> 

<Stream test.h264>
Feed feed.ffm
Format rtp
Noaudio
</Stream>

建议?

谢谢

推荐答案

我设法解决了一个类似的问题，其中最重要的部分是"-c:v mjpeg"和"-override_ffserver".

I managed to solve a similar problem with this, with the most important bits being the "-c:v mjpeg" and "-override_ffserver".

<Feed feed1.ffm>
  File /var/tmp/feed1.ffm
  FileMaxSize 1M
  Launch ffmpeg -i /dev/video0 -override_ffserver -c:v mjpeg -metadata:s:v rotate=0 -vf 'transpose=dir=clock,drawtext=fontcolor=white:fontfile=/usr/share/fonts/truetype/ubuntu-font-family/UbuntuMono-R.ttf:expansion=strftime:text=%FT%T:x=(w-text_w)/2:y=h-text_h-5' 
</Feed>

<Stream test>
  Feed feed1.ffm
  Format mpjpeg
  VideoSize 720x1280
  VideoFrameRate 5
  Strict -2
</Stream>

然后转到: http://localhost:8090/test

这最终显示了我的网络摄像头视频，但过滤器没有被ffserver默认设置覆盖，即:

This ended up finally showing my webcam's video with the filters not being overridden by ffserver defaults, i.e:

• 旋转90度以补偿网络摄像头的奇怪安装
• 时间戳记位于底部中心

我仍然对分辨率感到困惑，但是我希望这可以为您解决过滤器问题.

I'm still messing with the resolution, but I hope this helps solve the filters problem for you.
