#3497: multiple ffmpeg instances gives encoding error -------------------------------------+------------------------------------- Reporter: hemanth.he | Type: defect Status: new | Priority: critical Component: | Version: undetermined | unspecified Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Hi, Can anyone help me figure out to fix the problem below I am trying to encode multiple udp streams in HLS format. I run one by one instance (process) of encoding on the system. The application is working fine and I was able to encode, receive and play the streams using a player running on a STB (Set Top Box). The encoding was OK till running the 5 th instance. When I started running the 6th encoding instance on the system, the stream output starts freezing in all the 6 encoded outputs. I am using a Intel Xeon based Server with 24 cores and 32GB of RAM '''Here is my ffmpeg build info. ---- ffmpeg ffmpeg version N-61057-gec6d043 Copyright (c) 2000-2014 the FFmpeg developers built on Mar 4 2014 05:33:48 with gcc 4.6 (Debian 4.6.3-1) configuration: --prefix=/root/ffmpeg-static/64bit --extra-cflags='-I/root /ffmpeg-static/64bit/include -static' --extra-ldflags='-L/root/ffmpeg- static/64bit/lib -static' --extra-libs='-lxml2 -lexpat -lfreetype' --enable-static --disable-shared --disable-ffserver --disable-doc --enable-bzlib --enable-zlib --enable-postproc --enable-runtime-cpudetect --enable-libx264 --enable-gpl --enable-libtheora --enable-libvorbis --enable-libmp3lame --enable-gray --enable-libass --enable-libfreetype --enable-libopenjpeg --enable-libspeex --enable-libvo-aacenc --enable- libvo-amrwbenc --enable-version3 --enable-libvpx''' '''I am using the below command to encode one channel:''' {{{ ffmpeg -loglevel info -i "udp://@239.1.1.9:1009?fifo_size=1000000&overrun_nonfatal=1" -map 0:p:1:0 -map 0:p:1:1 -vcodec h264 -acodec aac -profile main -preset fast -g 12 -r 23.98 -s 256x144 -aspect 16:9 -b:v 166k -minrate 166k -maxrate 166k -bufsize 166k -vol 512 -b:a 128k -ac 2 -ar 48000 -strict experimental -flags -global_header -f ssegment -segment_time 10 -segment_wrap 30000 -segment_list Food_256x144_main_394.m3u8 -segment_list_flags +live -segment_list_size 6 -segment_format mpegts Food_256x144_main_394-%05d.ts -map 0:p:2:0 -map 0:p:2:1 -vcodec h264 -acodec aac -profile main -preset fast -g 12 -r 23.98 -s 640x360 -aspect 16:9 -b:v 722k -minrate 722k -maxrate 722k -bufsize 722k -vol 512 -b:a 128k -ac 2 -ar 48000 -strict experimental -flags -global_header -f ssegment -segment_time 10 -segment_wrap 30000 -segment_list Food_640x360_main_950.m3u8 -segment_list_flags +live -segment_list_size 6 -segment_format mpegts Food_640x360_main_950-%05d.ts -map 0:p:2:0 -map 0:p:2:1 -vcodec h264 -acodec aac -profile main -preset fast -g 12 -r 23.98 -s 960x540 -aspect 16:9 -b:v 1472k -minrate 1472k -maxrate 1472k -bufsize 1472k -vol 512 -b:a 128k -ac 2 -ar 48000 -strict experimental -flags -global_header -f ssegment -segment_time 10 -segment_wrap 30000 -segment_list Food_960x540_main_1700.m3u8 -segment_list_flags +live -segment_list_size 6 -segment_format mpegts Food_960x540_main_1700-%05d.ts -map 0:p:2:0 -map 0:p:2:1 -vcodec h264 -acodec aac -profile main -preset fast -g 12 -r 23.98 -s 1280x720 -aspect 16:9 -b:v 2772k -minrate 2772k -maxrate 2772k -bufsize 2772k -vol 512 -b:a 128k -ac 2 -ar 48000 -strict experimental -flags -global_header -f ssegment -segment_time 10 -segment_wrap 30000 -segment_list Food_1280x720_main_3000.m3u8 -segment_list_flags +live -segment_list_size 6 -segment_format mpegts Food_1280x720_main_3000-%05d.ts }}} ''I run the top command on the system and the output when I run the 6 th instance of the encoding is as follows'' Tasks: 831 total, 7 running, 824 sleeping, 0 stopped, 0 zombie Cpu(s): 42.0%us, 1.9%sy, 30.6%ni, 24.8%id, 0.0%wa, 0.0%hi, 0.7%si, 0.0%st Mem: 32844180k total, 12389892k used, 20454288k free, 32536k buffers Swap: 16490488k total, 7196k used, 16483292k free, 2747568k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 28365 root 20 0 12.1g 1.2g 3996 S 321.9 4.0 79:52.70 ffmpeg 28846 root 20 0 12.2g 1.1g 3720 R 315.0 3.5 76:45.76 ffmpeg 29334 root 20 0 11.8g 1.1g 4036 R 313.7 3.5 71:35.19 ffmpeg 30296 root 20 0 11.5g 1.1g 4036 R 296.2 3.5 67:50.69 ffmpeg 31405 root 20 0 11.9g 1.1g 4036 R 280.0 3.5 61:28.51 ffmpeg 29815 root 20 0 11.9g 1.1g 3952 S 255.6 3.4 60:18.52 ffmpeg ---- ''The sample error messages I am getting after adding the 6 th encoding instance is as below ( I have pasted only few lines of error message for reference as the log message is too long )'' ---- 619 [main] DEBUG com.ivz.streamer.FFmpegStreamer -

This is usually very bad advice. Not just for ffmpeg, for any program.

Agree that it is an unsafe advice, but there's a possible thread limitation associated to a specific user. Processing a live feed within allocated timing parameter requires all available hardware resources. AFAIK root has no limitations in that regard. -- Ticket URL: <https://trac.ffmpeg.org/ticket/3497#comment:9> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

If i use '''-preset slow''' then i can run only 2 instances. Starting 3rd one will create problem to the previous running instances,
Sounds as if this is a x264 performance issue that cannot be fixed within FFmpeg. -- Ticket URL: <https://trac.ffmpeg.org/ticket/3497#comment:11> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
