I use ffmpeg on Windows 8.1 x64 - Intel I7 - RAM 16MB to stream to Youtube a captured area of my laptop. I use 480p resolution. The internet connection is WiFi with a router with a 4G SIM card.
I experiment this problem: - the bitrate shown by ffmeg starts from about 350kbits/s and grows slowly and constantly until 2,500kbits/s, - while Youtube display in green: GOOD DATA RECEIVED, and then, as the bitrate grows, says in RED that the receiving data is to slow and users could experiment some problems - the resulting Youtube video is ok - the bitrate grows until 2,450 kbits/s and stay for 10-15 minutes - then goes down slowly and continuosly until around 1,500 fps the video becomes gray and only sound is received. At this point I stop and restart ffmpeg, and everything restarts again. Command line: "C:\\mbiWebTV\\programs\\ffmpeg\\bin_x64\\ffmpeg.exe" -thread_queue_size 512 -report -rtbufsize 100M -f dshow -i "audio=Missaggio stereo (Realtek High Definition Audio)" -rtbufsize 2000M -thread_queue_size 512 -f dshow -i "video=screen-capture-recorder" -vf "crop=717:367:018:043,scale=848x480,setsar=1" -vcodec libx264 -preset ultrafast -maxrate 2000 -bufsize 2000M -pix_fmt yuv420p -r 23.976 -keyint_min 24 -g 48 -x264opts no-scenecut -strict experimental -acodec libmp3lame -b:a 96k -ac 2 -ar 44100 -f flv rtmp://a.rtmp.youtube.com/live2/0qkb-yxkw-8pr2-4tmv -filter:v "crop=717:367:018:043" "c:\\mbiWebTV\\Capture\\Capture_20180106_123403.mkv" The log file has a lot of error messages like this at the beginning: cur_dts is invalid (this is harmless if it occurs once at the start per stream) and then no more, while the trasmission goes on. -- Sent from: http://www.ffmpeg-archive.org/ _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
