So i've got some UDP video being converted to h264/AAC inside the FLV format, i use either ffmpeg, vlc or MX player to view the video and it works but it has a problem. The UDP is a camera so the source is always unique.
A media player comes along and starts streaming the video at time 0 seconds, the video will play perfectly and play forever. I've watched the video for 60 seconds, i hit stop. I hit play again. The video starts playing at time 0 (showing me what i've already seen, like some sort of cache). I need it to play from "now", if the ffserver has been running for 10 minutes, i need it to play from "now", not video encoded from 10 minutes ago. It's like some sort of time shift or caching. I'm just using the URL http://myserver.com/channel1.flv to view the video I've also tried using the URL http://myserver.com/channel1.flv?date=02:22:48 The URL is generated using php and the media player is redirected to the URL using <?php > > $_GET = filter_input_array(INPUT_GET, FILTER_SANITIZE_STRING); > > $channel = $_GET['channel']; > > $date = date('H:i:s', strtotime('-1 second')); > > //echo "Location: http://185.86.160.195:4004/$channel.flv?date=$date";; > > header("Location: http://185.86.160.195:4004/$channel.flv?date=$date";); > > exit; > > ?> > > So im trying to get it it play from "now" minus 1 second. How do i stop this? Is it a bug? ffserver.conf Port 11100 > BindAddress 0.0.0.0 > MaxHTTPConnections 2000 > MaxClients 1000 > MaxBandwidth 300000 > CustomLog - > #NoDaemon > <Feed s1.ffm> > File /tmp/channel1.ffm > FileMaxSize 64M > ACL allow 127.0.0.1 > </Feed> > <Stream channel1.flv> > Format flv > Feed channel1.ffm > VideoCodec libx264 > VideoFrameRate 24 > VideoBitRate 128 > VideoSize 640x480 > AVOptionVideo crf 23 > AVOptionVideo preset medium > # for more info on crf/preset options, type: x264 --help > AVOptionVideo flags +global_header > AudioCodec aac > Strict -2 > AudioBitRate 64 > AudioChannels 2 > AudioSampleRate 44100 > AVOptionAudio flags +global_header > Preroll 15 > </Stream> Input: ffmpeg -i 'udp://@224.2.2.1:3000?fifo_size=100000000' > http://127.0.0.1:11100/channel1.ffm > ffmpeg version: ffmpeg version 2.8.1-static http://johnvansickle.com/ffmpeg/ Copyright (c) > 2000-2015 the FFmpeg developers built with gcc 4.9.3 (Debian 4.9.3-4) configuration: --enable-gpl --enable-version3 --disable-shared > --disable-debug --enable-runtime-cpudetect --enable-libmp3lame > --enable-libx264 --enable-libx265 --enable-libwebp --enable-libspeex > --enable-libvorbis --enable-libvpx --enable-libfreetype --enable-fontconfig > --enable-libxvid --enable-libopencore-amrnb --enable-libopencore-amrwb > --enable-libtheora --enable-libvo-aacenc --enable-libvo-amrwbenc > --enable-gray --enable-libopenjpeg --enable-libopus --enable-libass > --enable-gnutls --enable-libvidstab --enable-libsoxr --enable-frei0r > --enable-libfribidi --cc=gcc-4.9 libavutil 54. 31.100 / 54. 31.100 libavcodec 56. 60.100 / 56. 60.100 libavformat 56. 40.101 / 56. 40.101 libavdevice 56. 4.100 / 56. 4.100 libavfilter 5. 40.101 / 5. 40.101 libswscale 3. 1.101 / 3. 1.101 libswresample 1. 2.101 / 1. 2.101 libpostproc 53. 3.100 / 53. 3.100 Hyper fast Audio and Video encoder usage: ffmpeg [options] [[infile options] -i infile]... {[outfile options] > outfile}... I've also tried using ffmpeg from Ubuntus repository which is version 7:2.8.6+git1~trusty Part of my ffserver restart script i delete all FFM files to ensure that no cache is left behind. The newly generated FFM files are repeated. The odd thing is that this problem does not happen all the time, it seems quite random. _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user
