* Revert "avcodec/wcmv: Avoid copying frames if they are unchanged"James Almer2019-09-041-3/+1
| | | | | | This reverts commit 976dae8b32f48d17cccfd6b19d2beb01770dfa7c. An alternative approach to reduce frame copying will follow.
* avcodec/wcmv: use ff_reget_buffer()James Almer2019-09-041-14/+9

* avcodec/decode: add a flags parameter to ff_reget_buffer()James Almer2019-09-0448-57/+58
| | | | | | | | | | 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>
* avformat/mpegts: Check if ready on SCTE receptionAnthony Delannoy2019-09-031-0/+7
| | | | | | | | On some DVB stream SCTE-35 data packet are available before the end of MpegTSContext initialization. We have to check if it is the case to avoid a SEGFAULT. Signed-off-by: Marton Balint <cus@passwd.hu>
* configure: ensure --enable-omx-rpi uses rpi-specific IL headersAman Gupta2019-09-031-3/+6
| | | | | | | | | | | | 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>

* avformat: Add ZeroMQ as a protocolAndriy Gelman2019-09-028-2/+254
| | | | | | | | | 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>
* avcodec/omx: fix xFramerate calculationAman Gupta2019-09-021-2/+2
| | | | | | | | | | | 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.

* avformat/mpegtsenc: fix flushing of audio packetsMarton Balint2019-09-021-17/+2
| | | | | | | | | | | | | | | | | | | | | | | | 7d097a0fc57f0fa8385962a539c657c2f40b5ed0 had the same purpose as 3700f655c55e2001b57215210b957b169d66b50f 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>

* avfilter/vf_delogo: unbreak fatePaul B Mahol2019-09-021-0/+12
| | | | | | | | | It is not clear what was real intention of previous commit to this filter. It was not working correctly, hopefully this is fixed now. It never checked that new x/y/w/h are actually valid, hopeffully this is fixed now. It uses named variables in expressions that are never set, still not fixed. It does not set named variables that uses actual frame widht/height, making actual expressions less usable for our users, still now fixed.

* lavc/tiff: Enable decoding of LinearRaw imagesNick Renieris2019-09-021-1/+1
| | | | | | | | | | | | | "LinearRaw" is a value that the PhotometricInterpretation tag can be set to on DNG images that contain color information for all channels instead of being bayer-encoded ("CFA" value). The DNG decoder is complete enough that we can enable this now. Sample: - http://www.rawsamples.ch/raws/nikon/SCANNER_NIKON_LS5000.DNG Signed-off-by: Nick Renieris <velocityra@gmail.com>

| | | | | | | | | Also, ensure no false positives when determining DNG bayer images, by setting them in tiff.c instead of relying on a heuristic. There's no way to determine this just from the JPEG data, so we have to pass this information from outside the MJPEG decoder. Signed-off-by: Nick Renieris <velocityra@gmail.com>
