Use ffmpeg/avconv to re-stram a combined stream ?
28 novembre 2014, par TerminelloHaving two separate stream sources (audio and video) each from an IP-camera, I would like to
- combine them into a single stream
- save this into a file (using segmentation)
- re-stream (specific word unknown for me, sorry) the combined stream so that other users may access it without having to combine the streams on their own
The first two things : I have already accomplished like that :
ffmpeg -use_wallclock_as_timestamps 1 -f mjpeg -i 'http://camera.ip.address/videostream.cgi?user=username&pwd=password' -i 'http://camera.ip.address/videostream.asf?user=username&pwd=password' -map 0:v -map 1:a -acodec copy -vcodec copy -f segment -segment_time 3600 -reset_timestamps 1 'out%03d.mkv'
Credits go to santiago (foscam.com forums)
But how to make this stream available on the LAN at the same time while being recorded and saved to HDD ?
BTW : You might ask, why do I need this : Because many clients do not have capabilitys to combine a stream from multiple sources, so I set up a server which does this task and clients do not go directly to the audio/video source (IP-camera) but catch the newly generated stram = : the idea.

UDP : join multicast group on the interface specified with &localaddr=
13 décembre 2013, par Stoian IvanovUDP : join multicast group on the interface specified with &localaddr=
When joining multicast groups, ffmpeg was using INADDR_ANY as interface address
which leads to enabling the multicast group on the interface with "default gateway".
Often multicast traffic is received over dedicated interface, which scenario ffmpeg was
unable to handle. With this patch, ffmpeg will enable multicast group to the interfaces
configured with address specified in &localaddr= parameter of udp :// URL. To avoid
loacal_addr resolve at udp_close(...) the UDPContext structure was extended with
struct sockaddr_storage local_addr_storage member, which is populated in udp_open(..)
and passed to udp_join_multicast_group() and udp_leave_multicast_group().Signed-off-by : Stoian Ivanov <s.ivanov@teracomm.bg>

Support broadcast destination for udp protocol
9 avril 2014, par Olivier LangloisSupport broadcast destination for udp protocol
Use the required socket option SO_BROADCAST to be able to stream to a broadcast
address.Prior to the patch, trying to stream to a broadcast address was resulting to the
following error :av_interleaved_write_frame() : Permission denied
The patch has been tested with :
ffmpeg -f v4l2 -framerate 30 -input_format yuyv422 -video_size 640x480 -i /dev/video0 \
-c:v libx264 -profile:v high -preset ultrafast -tune zerolatency -b:v 500k -pix_fmt yuv420p \
-f mpegts udp ://192.168.1.255:5004 ?broadcast=1I have added an option to let the user explicitly request broadcast in order to avoid
ffmpeg to broadcast unintentionally.Signed-off-by : Olivier Langlois <olivier@trillion01.com>
