Has anyone tried UDP streaming of a live capture source, such as a BlackMagic card, encoded to mpeg2ts to a Pico QAM IP modulator?
The modulator is reporting both PAT and PMT faults and will not play either the audio or video stream . I have tried both direct streaming to the Pico address and to a multicast address without any luck. If I use multicast I can see the stream in ffplay and VLC. I am able to stream mpegts files to the QAM using LeadTools multi-media kit but I can't seem to get their sample apps to work at all for live capture using a Blackmagic card. I looked at some past posts that mention specifying pkt_size=1316 to prevent fragmentation but this didn't seem to help. I have tried all sorts of combinations on the command line, this is the last thing I was trying: ffmpeg -f decklink -i "DeckLink Mini Recorder (2)@9" -vcodec mpeg2video -streamid 0:50 -streamid 1:52 -pix_fmt yuv420p -vb 15000000 -minrate 15000000 -maxrate 15000000 -bufsize 7500000 -r 29.97 -async 1 -acodec mp2 -ac 2 -ab 224k -ar 44100 -f mpegts -mpegts_pmt_start_pid 0x1f00 -mpegts_start_pid 0x0f00 -mpegts_m2ts_mode 1 udp://239.255.12.42:6666?localaddr=10.10.10.201&reuse=1&overrun_nonfatal=1&p kt_size=1316&ttl=16&broadcast=1 Any help is appreciated. _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user
