FFMPEG - How to record multiple RTMP streams into multiple files
11 juillet 2014, par user3146313I tried the following, but it does not work.
ffmpeg -i rtmp://83.229.210.89/RAZTV/BTVraztv1 -map 0 -b:v 900k -vcodec libx264 -acodec aac -b:a 256k -strict -2 -t 3600 /media/TV_1T_3T_6/ffmpegtest/ort.mp4 -i rtmp://mirtv.cdnvideo.ru/mirtv-live/mirtv600.sdp -map 1 -b:v 900k -vcodec libx4 -acodec aac -b:a 256k -strict -2 -t 3600 /media/TV_1T_3T_6/ffmpegtest/mir.mp4 -i rtmp://chanson.cdnvideo.ru/chanson-live/shansontv.sdp -map 2 -b:v 900k -vcodec libx264 -acodec aac -b:a 256k -strict -2 -t 3600 /media/TV_1T_3T_6/ffmpegtest/shansontv.mp4 -i rtmp://83.229.210.89:1935/TROTV/BTVtro0 -map 3 -b:v 900k -vcodec libx264 -acodec aac -b:a 256k -strict -2 -t 3600 /media/TV_1T_3T_6/ffmpegtest/tro.mp4Looks like it hangs on a second stream and no movement. S.O.S. Please help.
I have 4 stream URLs. I want them to be recording together at the same time.With one ffmpeg command:
I want: rtmp://83.229.210.89/RAZTV/BTVraztv1 to record into file: /media/TV_1T_3T_6/ffmpegtest/ort.mp4
I want: rtmp://mirtv.cdnvideo.ru/mirtv-live/mirtv600.sdp to record into file: /media/TV_1T_3T_6/ffmpegtest/mir.mp4
I want: rtmp://chanson.cdnvideo.ru/chanson-live/shansontv.sdp to record into file: /media/TV_1T_3T_6/ffmpegtest/shansontv.mp4
I want: rtmp://83.229.210.89:1935/TROTV/BTVtro0 to record into file: /media/TV_1T_3T_6/ffmpegtest/tro.mp4The log that I get right now is :

Record and livestream xvfb to facebook with audio
7 janvier 2017, par boygiandiI can live a Xvfb screen to facebook with this ffmpeg command :
ffmpeg -r 30 -framerate 5 -f x11grab -i :1045.0 -f lavfi -i anullsrc -video_size 640x480 -codec:v libx264 -x264-params keyint=60 -bufsize 500k -c:a aac -ac 1 -ar 44100 -b:a 128k -f flv "rtmp ://rtmp-api.facebook.com:80/rtmp/10208339883840092 ?ds=1&s_l=1&a=ATizxYY-84bloD-H"
But it doesn’t contain audio. I know that -f lavfi -i anullsrc mean no audio. I tried many ways but I can’t make it record audio from Xvfb screen and live to facebook.
Any one can help ? -
JavaCV record video in Android
11 janvier 2017, par wyxI want to record video quiet and without preview in Android. So I choice MediaRecorder but I could record only without preview but what make me crazy is that when MediaRecorder start or stop it will with a sound dee.... I try many methods about that . But I think it perhaps sth related to the OS of the mobile. So I try JavaCV because I also want to have a Live function in my app.
But JavaCV spent me to too much time to solve some strange problems because it’s my first time to do sth about C++ src and video.
