Hi Marton,
Thanks for replying. And without resampling you mean? Sorry, Im far away
of having video skills.
Do not top post. Try to figure out based on the ffmpeg command line manual
what your command actually does.
./ffmpeg -re -f decklink -i "DeckLink SDI 4K@2" -c:v mpeg2video -pix_fmt
yuv420p -aspect 16:9 -deinterlace -sc_threshold 1000000000 -b:v 3.5M
-minrate:v 3.5M -maxrate:v 3.5M -bufsize:v 2.4M -acodec mp2 -ac 2 -b:a
128k -ar 44100 -af aresample=async=1:min_hard_comp=0.100:first_pts=0
-metadata service_name="TVT" -mpegts_service_id 123 -f mpegts
udp://224.0.0.247:5001?pkt_size=1316
With -ar 44100 you are resampling the initial sample rate of the captured
source (48000) to 44100. You are also manually specifying a resample
filter with -af resample. Try your encoding without these options.
Regards,
Marton
