Hi sat, I may have a solution below. Long shot though.

Does that site provide older *and* recent git builds, so that you could iterate through to see when it stopped working? I guess that would be too much of a hassle for you, judging from the below. > If anyone can enlighten me as to why this no longer works in ffmpeg > 3.0 I would very much appreciate it. There's probably really meaningful info in the console output. ;-) > I cannot show you ffmpeg's output because it is not being run from a > command prompt, so I don't see any output and since this is a live > stream rather than a file I don't even think there is any way I could > see any output from ffmpeg. Using the "-report" option will let ffmpeg create files named ffmpeg-YYYYMMDD-HHMMSS.log in the "current" directory. Perhaps you could create and grab those. > pipe:///usr/local/bin/ffmpeg -loglevel fatal -i > http://127.0.0.1:9981/stream/channelnumber/CHANNEL_NUMBER -c:v copy -c:s copy > -c:d copy -c:t copy -filter_complex > +[0:1][0:2][0:3]amerge=inputs=3,pan=5.1|FL=c0|FR=c1|FC=c2|LFE=c3|BL=c4|BR=c5 > -c:a eac3 -f mpegts pipe:1 I have an idea what the issue could be though! It may be this recent commit: http://git.videolan.org/gitweb.cgi/ffmpeg.git/?p=ffmpeg.git;a=commit;h=470749703e3cec3a86bc556648a20f0ec1701954 It changes the format of the output MPEG-TS w.r.t. E-AC3 audio (which you are using). If you add "-mpegts_flags system_b", it should revert the behavior. Please see if that helps. It's a wild guess. (BTW, if that's it, then that's something we probably could *not* have seen from the console logs. ;-)) Moritz _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user
