Some decoders may not need a writable buffer in some specific cases, but only a reference to the existing buffer with updated frame properties instead, for the purpose of returning duplicate frames. For this, the FF_REGET_BUFFER_FLAG_READONLY flag is added, which will prevent potential allocations and buffer copies when they are not needed. Signed-off-by: James Almer <jamrial@gmail.com>

When compiling natively on an RPI where libomxil-bellagio-dev was also installed, `check_headers OMX_Core.h` succeeded and the -isystem compiler flag was never added to the build. For non-native builds, the error message now mentions the raspberrypi/firmware repository where the RPI specific headers are available. Signed-off-by: Aman Gupta <aman@tmm1.net>

When ffmpeg was streaming, multiple clients were only supported by using a multicast destination address. An alternative was to stream to a server which re-distributes the content. This commit adds ZeroMQ as a protocol, which allows multiple clients to connect to a single ffmpeg instance. Signed-off-by: Marton Balint <cus@passwd.hu>

Integer overflow in the Q16 framerate calculation was sending invalid values to the OMX encoder. On the RPI4, this manifested as bitrate controls being ignored on video streams with 60000/1001 framerates. Video streams with 30000/1001 framerates were not affected.

7d097a0f had the same purpose as 3700f655 but 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>
