7d097a0fc5had the same purpose as3700f655c5but the former is much simpler, so let's remove the latter. Unfortunately both checks were wrong, because in order to make sure DTS > PCR we have to give us some headroom, so instead of using a dts_difference < max_delay check let's use a dts_difference < max_delay/2 check. Fixes DTS < PCR errors with this command line: ./ffmpeg -loglevel verbose -y -f lavfi -i \ "testsrc=s=64x64:d=20,split=2[out0][tmp1];[tmp1]vflip[out1];sine=d=20,asetnsamples=1000[out2]" \ -flags +bitexact -fflags +bitexact -sws_flags +accurate_rnd+bitexact \ -codec:v libx264 -codec:a mp2 -b:a 32k -pix_fmt yuv420p \ -map '0:v:0' \ -map '0:v:1' \ -map '0:a:0' \ -muxrate 800000 \ -program st=0:st=2 -program st=1:st=2 -program st=2 -program st=0 -f mpegts out1.ts Signed-off-by: Marton Balint <cus@passwd.hu>
