FFMPEG: encode x265, container mpeg2 ts, stream-STARTCODE MISSING

Question

I am trying to encode a video with FFMPEG x265, put it into MPEG2 TS and then stream it over UDP. Then receive on another PC and save it. Perform PSNR.

The encoding works fine, but when I try to stream I get the error:

[mpegts @ 00000000050b0520] HEVC bitstream error, startcode missing, size 1436 data 00000100

• Step 1- Encoding:

ffmpeg -re -i test.ts -r 25 -b:v 2500k -preset medium -c:v libx265 -x265-params crf=27 -y -f mpegts test1.ts

No error, everything fine.

• Step 2- Streaming:

Start code missing.

When I do the steps above with x264 everything works fine. I can stream the video and I can receive it on the other side. Any idea what is wrong? Is this a BUG?

Commands for x264:

ffmpeg -re -i test.ts -r 25 -b:v 2500k -preset medium -c:v libx264 -x264-params crf=27 -y -f mpegts test1.ts

ffmpeg -re -i test1.ts -c copy -f mpegts udp://172.18.60.47:1234

Thanks for the help!!
