* avformat/hlsenc: Fix memleak when using single_fileAndreas Rheinhardt2019-09-14
| | | | | | | | | | This commit fixes a memleak in the hls muxer when one uses a single file as output. It has been forgotten to free the temporary buffers used to write the packets so that the size of the leaks basically amounts to the size of the output file. This commit adds the necessary free.

* avformat: Add ZeroMQ as a protocolAndriy Gelman2019-09-02
| | | | | | | | | 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>
* avformat/mpegtsenc: fix flushing of audio packetsMarton Balint2019-09-02
| | | | | | | | | | | | | | | | | | | | | | | | 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>

* avformat/utils: return pending IO error on EOF in av_read_frame()Marton Balint2019-08-31
| | | | | | | | | | | | | | | | | | | | | | | | | avio_feof() returns true both in case of actual EOF and in case of IO errors. Some demuxers (matroska) have special handling to be able to return the proper error for this exact reason, e.g.: if (avio_feof(pb)) { if (pb->error) { return pb->error; } else { return AVERROR_EOF; } } However, most of the demuxers do not, and they simply return AVERROR_EOF if avio_feof() is true, so there is a real chance that IO errors are mistaken for EOF. We might just say that the API user should always check the IO context error attribute on EOF to make sure no IO errors happened, but not even ffmpeg.c does this. It should be more intuitive to the API user if we simply return the IO error as the return value of av_read_frame() instead of AVERROR_EOF. Signed-off-by: Marton Balint <cus@passwd.hu>

* avformat/mpegts: fix teletext PTS when selecting teletext streams onlyMarton Balint2019-08-31
| | | | | | | | | | | | | | | After a1b4f120c031e6697bac9fd8c725d9c37ee36d13 the teletext PTS values were set to AV_NOPTS_VALUE if the stream of the PCR pid was discarded. What actually matters is that if we parse the PCR of the PCR PID or not, so let's use the cached discard value of the actual PCR PID instead of the stream discard value, which may be different. Also fixes ticket #7567, which was caused by the fact that teletext PTS values were not touched if the PCR pid was discarded even before a1b4f120c031e6697bac9fd8c725d9c37ee36d13.

* avformat/mpegtsenc: get rid of packet counting for sdt/pat/pmtMarton Balint2019-08-23
| | | | | | | | | | | | | The packet counting based approach caused excessive sdt/pat/pmt for VBR, so let's use a timestamp based approach instead similar to how we emit PCRs. SDT/PAT/PMT period should be consistent for both VBR and CBR from now on. Also change the type of sdt_period and pat_period to AV_OPT_TYPE_DURATION so no floating point math is necessary.
