Hello
I'm trying to transcoding live UDP stream from h264 codec to mpeg2 with
ffmpeg built with --enable-libmfx
We need this because our CATV IP-to-RF-PAL gateway modulator only works
with mpeg2
console command i use:
ffmpeg -re -i udp://234.5.100.9:1234 -vcodec mpeg2_qsv -b:v 2M -minrate:v
2M -maxrate:v 2M -bufsize:v 1.4M -b:a 192k -flush_packets 0 -f mpegts
-metadata service_provider="Home.net" -metadata service_name="OTR" udp://
234.5.100.225:1234?pkt_size=1316
console output:
[root at iptv share]# ffmpeg -re -i udp://234.5.100.9:1234 -vcodec mpeg2_qsv
-b:v 2M -minrate:v 2M -maxrate:v 2M -bufsize:v 1.4M -b:a 192k
-flush_packets 0 -f mpegts -metadata service_provider="Home.net" -metadata
service_name="OTR" udp://234.5.100.225:1234?pkt_size=1316

Output UDP stream is broken and won't play on VLC (sometimes plays,
sometimes not with only sound). Hardware RF-PAL modulator for CATV says is
audio and video is scrambled

P.S. If i use mpeg2video instead mpeg2_qsv codec - all works correctly.
But i need hardware accelerated solution
