Facebook live video can only be previewed while streaming my Mac screen
24 janvier 2017, par iownthegameI use the following ffmpeg command to share my screen streaming to Facebook.
ffmpeg -f avfoundation -r 10 -video_size 352x288 -i "0" -c:v h264 -f flv
"rtmp://rtmp-api.facebook.com:80/rtmp/1269140699772419?ds=1&a=AaYsXcYcdHQrrrUF"then I can see the video preview scenes
however, once I press the ’Go Live’ button, and go to my facebook page, I can find a post said I am Live Now. When I press the ’play button’, there are only black scenes that last for 1 2 seconds, and the video ends.
And there is also a weird thing, the video can be played when I end up the live stream. When refreshing the page, I can find a post said I was Live, the video of this post can be played successfully.
Anyone knows why the video can be watched when previewing and finishing live but not the exact live moment ?
[updated]
During the live streaming period, if I press the play button, there are only 1 2 seconds black scenes and the live stream ends.
However if I press the video frame again, another modal pops up then I can see the live streaming. Is it a facebook bug ?

How to watch or download periscope live streams from start ?
10 septembre 2019, par SanchitI am trying to figure how watch/download a periscope livestream from it’s starting point. The app doesn’t let go back more than 2 minutes so I tried downloading as someone told me it downloads from beginning but it didn’t. It started from the current time.
I tried running :

ffmpeg rtmp webcam live stream iphone/pad segment size too big
1er février 2013, par Foo BarazzI'm transcoding a rtmp stream from a red5 server for use to live stream on a iphone or ipad device. I built latest ffmpeg version from git repo using the built in segmenter to create .ts files and m3u8 playlist file using the following :
ffmpeg -probesize 50k -i "rtmp://localhost/oflaDemo/red5StreamDemo live=1" \
-c:v libx264 -b:v 128k -vpre ipod320 -flags -global_header -map 0 \
-f segment -segment_time 3 -segment_list foo.m3u8 -segment_list_flags +live \
-segment_list_type m3u8 -segment_list_size 5 -segment_format mpegts foo%d.tsThis works fine, but I can't get the segment size smaller than about 12 sec even set to 3 (-segment_time 3). It seems to be caused by libx264 vcodec.
Am I missing any flag ?By the way, you can simple run the ffmpeg command above successfully by starting red5 SimpleBroadcaster example.
