Hello! I try to solve a problem which seems to be very simple. There is a source file which is to be streamed as multicast (UDP) infinitely. Ok, not even infinitely, just once. What is the problem? Terrible bitrate range. Here is my source file:
Input #0, mpegts, from 'test.ts': Duration: 00:08:14.46, start: 1.458667, bitrate: 4490 kb/s Program 1 Metadata: service_name : Service01 service_provider: FFmpeg Stream #0:0[0x100]: Video: h264 (High) ([27][0][0][0] / 0x001B), yuv420p(progressive), 1920x1080 [SAR 1:1 DAR 16:9], 25 fps, 25 tbr, 90k tbn, 50 tbc Stream #0:1[0x101](und): Audio: aac (LC) ([15][0][0][0] / 0x000F), 48000 Hz, stereo, fltp, 139 kb/s I try to stream it: ffmpeg -threads 0 -re -stream_loop -1 -i test.ts -c copy -f mpegts "udp://@235.5.2.193:1234?pkt_size=1316" But when I analyze the result multicast I see bitrate jumps from almost zero to 12 Mbps: http://image.ibb.co/cqrhPw/ffmpeg_stream.png I made a lot of attempts to change some parameters but nothing helped. Is it possible to get smoother bitrate? I don't even dream about CBR but I would be happy to get 3-5 Mbps at least.
