| 1 | | Yesterday, I got the latest snaphot from GIT and tested the case. |
| 2 | | On a CBR test, if outpur bandwidth rate is high, some decoders/TS analyze SWs give PCR accuracy and repetition error (very rare). |
| 3 | | |
| 4 | | Example: |
| 5 | | ffmpeg -i pipe -aspect 16:9 -fflags +genpts -vcodec libx264 -preset ultrafast -vb 25000k -minrate 25000k -maxrate 25000k -bufsize 2500k -muxrate 27000k -tune stillimage -qmin 20 -pix_fmt yuv420p -vbsf h264_mp4toannexb -strict experimental -acodec libfdk_aac -ab 128k -flush_packets 0 -f mpegts 'udp://225.2.1.1:1234?pkt_size=1316' |

| 7 | | This works fine. Time to time on some decoders (like Ericsson) make black frame. But no PCR error. |

| 9 | | ffmpeg -i pipe -aspect 16:9 -fflags +genpts -vcodec libx264 -preset ultrafast -vb 50000k -minrate 50000k -maxrate 50000k -bufsize 10000k -muxrate 54000k -tune stillimage -qmin 20 -pix_fmt yuv420p -vbsf h264_mp4toannexb -strict experimental -acodec libfdk_aac -ab 128k -flush_packets 0 -f mpegts 'udp://225.2.1.1:1234?pkt_size=1316' |

| 11 | | In this case, it reports PCR accuracy and repetition error and decoders gives alarm as well. |
