我正在尝试使用 ffserver 从相机模块传输视频。想法是让raspivid
输出 h264,然后让 ffmpeg/ffserver 传输它而无需重新编码。
我的服务器配置是
HTTPPort 8090
HTTPBindAddress 0.0.0.0
MaxHTTPConnections 8
MaxClients 4
MaxBandwidth 1000
CustomLog -
#NoDaemon
<Feed feed1.ffm>
File /tmp/feed1.ffm
FileMaxSize 5M
ACL allow 127.0.0.1
</Feed>
<Stream live.flv>
Feed feed1.ffm
NoAudio
</Stream>

我跑
ffserver -f server.conf &
进而
raspivid -t 0 -w 640 -h 480 -b 1024000 -fps 5 -ih -n -o - | \
ffmpeg -i - -c:v copy -r 5 -an -f flv -override_ffserver \
http://localhost:8090/feed1.ffm
然而 ffmpeg 抱怨
[flv @ 0x215e520] Timestamps are unset in a packet for stream 0. This is deprecated and will stop working in the future. Fix your code to set the timestamps properly
Thu Mar 3 02:58:36 2016 127.0.0.1 - - [POST] "/feed1.ffm HTTP/1.1" 200 276
av_interleaved_write_frame(): Connection reset by peer

[flv @ 0x215e520] Failed to update header with correct filesize.
Error writing trailer of http://localhost:8090/feed1.ffm: Connection reset by peer
然后退出。
我该如何解决?
顺便说一句,我测试了raspivid
一下ffmpeg
,
raspivid -t 0 -w 640 -h 480 -o - | ffmpeg -i - -c:v copy test.mkv
并且工作正常。
答案1
当 ffmpeg 的输出正在流式传输到 ffserver 时,设置输出格式将导致此错误。
您已在 ffserver 配置文件中指定了输出格式,因此请-f flv
从 ffmpeg 命令中删除:
raspivid -t 0 -w 640 -h 480 -b 1024000 -fps 5 -ih -n -o - | \
ffmpeg -i - -c:v copy -r 5 -an -override_ffserver \
