Доброго дня!
Пытался настроить рестриминг MJPEG->RTSP. Конфиг ffserver
Port 12345
RTSPPort 554
BindAddress 0.0.0.0
<Feed webcam.ffm>
File /tmp/webcam.ffm
FileMaxSize 200K
Launch ffmpeg -i http://tcp:port/cgi/mjpg/mjpg.cgi
</Feed>
<Stream webcam>
Feed webcam.ffm
Format rtp
VideoCodec mpeg2video
VideoFrameRate 30
VideoBufferSize 80000
VideoBitRate 300
VideoSize 640x480
PreRoll 1
NoAudio
</Stream>
При подключении (ffprobe rtsp://localhost:554/webcam) сервер падает в Segmentation fault
Program received signal SIGSEGV, Segmentation fault. av_freep (arg=arg@entry=0x10) at libavutil/mem.c:247 247 memcpy(&val, arg, sizeof(val));
Ткните носом, может я чего в конфиге напутал ?! Собирал из исходников, по оффициальной инструкции, сервер под VMware.
