rtmp server as output
by Haris Zukanovic 27 Apr '15

27 Apr '15

Hello, This command works... waits and accepts only 1 rtmp client then exits after the client has disconnected. ffmpeg -f lavfi -i testsrc=size=512x288 -f lavfi -i "aevalsrc=0|0:d=5" -pix_fmt yuv420p -c:v libx264 -s 512x288 -preset veryfast -profile:v baseline -strict -2 -c:a aac -f flv -listen 1 rtmp://127.0.0.1:1935/test Is there a way to serve 2 rtmp clients with one ffmpeg process (1 transcoding) and make it accept new connections forever? Maybe there is another prefered way or protocol to let multiple clients connect and pull from the ffmpeg? In my case I have to use a reliable (tcp) protocol... and the idea is to not interrupt ffmpeg when a clients disconnects and allow it to reconnect without having to restart the transcoding process. -- -- Haris Zukanovic

--enable-freior ignored
by Roger Pack 27 Apr '15

27 Apr '15

Hello. I notice that "typically" if I call out to enable something with configure, and it "can't use it" it fails the configure script. however, got a note that with --enable-frei0r and --enable-filter=frei0r if it fails, it fails fails silently (other than posting a reference to an unlocatable function in config.log), and therefore the frei0r filter interface is not incorporated into libavfilter and FFmpeg. Cheers! -r

Re: [FFmpeg-user] bat file problem
by mB 26 Apr '15

26 Apr '15

greetings, I have ffmpeg.exe, 7 BMP images (i.e. img1.bmp, img2.bmp, ...) and the following bat file all located in the same Wins folder: @echo off ffmpeg.exe -framerate 1/10 -f image2 -i img%1d.bmp temp.avi PAUSE This does not work when double clicked - and returns the error: “Could find no file with path ‘imgd.bmp’ and index in the range 0-4. imgd.bmp: no such file or directory.” BUT if I use this bat file: @echo off CMD Pause and type in “ffmpeg.exe -framerate 1/10 -f image2 -i img%1d.bmp temp.avi” – without the quote marks (the exact same command) - the bat file works (combines the img files and creates a avi video – slideshow) Any help to get the bat file to just automatically exe the command instead of having to enter it manually at the cmd prompt? Thanks in advance for any help, mikeB

can "Press [q] to stop, [?] for help" be disabled in FFmpeg.exe? Please help!
by James Heliker 26 Apr '15

26 Apr '15

Hello I'm trying to automate the calling of FFmpeg via Windows command line, and everything is working well until FFmpeg actually begins an encode and prints out: "Press [q] to stop, [?] for help" Is it possible to disable that functionality that seems to be re-opening a stream somehow? It is crashing everything I have tried to use, even sysinternals' PSExec and the lesser-known PAExec counterpart (http://www.poweradmin.com/paexec/) It believe things would be perfect if I could somehow get FFmpeg to run without doing that extra "listen" for whether I want to push "q" or "?"...

Concurrent Segment/Concat Read/Writes
by Robert Nagy 26 Apr '15

26 Apr '15

I'm using ffmpeg to segment/concat a 120Mbit/s file in 2 second segments to/from a HTTP server. The problem is that ffmpeg only writes/reads one segment at a time which doesn't fully use all available bandwidth. Each request to/from the server has a limit of 10MB/s. However using 5+ concurrent request it can get all the way up to 50+ MB/s. Is there some way I can get the segment/concat muxer/demuxer to run several requests concurrently? If not I'll have to modify ffmpeg myself and would in that case appreciate any tips.

Any suggestions on action camera for streaming?
by Ricardo Kleemann 26 Apr '15

26 Apr '15

Hi I'm having a hard time researching action cameras because none of the ones with wifi mention much about streaming, other than ios/android apps. I wanted to have ffmpeg access a live stream from a camera I know it's possible to connect to a gopro to access http streaming. Does anyone know of any others that enable a url that could be used with ffmpeg? Thanks Ricardo

New user trying to get things working
by En Figureo Canal 26 Apr '15

26 Apr '15

Hello. This is my first post to the list. I've done some research about what I'm trying to accomplish but, can't really find the correct answer to my problem: I'm trying to configure a ffserver to stream feeds and files locally but, first I'm trying to get it to work with files. I have hundreds of videos on a server I would like to watch on my tv and smartphones at different quality and rates since bandwidth could be an issue. How can I have clients use specific amount of bandwidth for each stream, for example I would like to make clients not to use more than 1024Kbit/s. If I have four clients watching a stream that would be each 1024, 4 x 1024 = 4096 TOTAL. Does this type of "shaping" needs to be configured the os side or simply by assigning a max bit rate: Here's what I try doing in my ffserver.conf: <Stream video.sdp> > Format rtp > File "/root/videos/video1.mp4" > AudioBitRate 96 > AudioSampleRate 44100 > VideoBitRate 1024 > VideoFrameRate 30 > VideoCodec libx264 > > VideoCodec libx264 > VideoSize 720x480 > AVOptionVideo crf 23 > AVOptionVideo flags +global_header > Preroll 15 > </Stream> The video's specs are as follow: Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'videos/video1.mp4': > Metadata: > major_brand : mp42 > minor_version : 0 > compatible_brands: isommp42 > creation_time : 2013-11-26 23:10:14 > Duration: 01:27:39.02, start: 0.000000, bitrate: 3035 kb/s > Stream #0:0(und): Video: h264 (High) (avc1 / 0x31637661), yuv420p, > 1280x720, 2840 kb/s, 25 fps, 25 tbr, 50 tbn, 50 tbc (default) > Metadata: > handler_name : VideoHandler > Stream #0:1(und): Audio: aac (LC) (mp4a / 0x6134706D), 44100 Hz, > stereo, fltp, 192 kb/s (default) > Metadata: > creation_time : 2013-11-26 23:15:21 > handler_name : IsoMedia File Produced by Google, 5-11-2011 The ffserver.conf does not work, I checked the server bw consumption or traffic with iptraf and is over 6M. Am I doing something wrong? Please guide me to where I can find more info to correct my problem. Thanks in advanced for your time and guidance.

I've been trawling google on this but can't work out why this is. if I trim the command down and leave out the dual target and just stream to rtmp only it works fine, I get an image. Can anybody help? I've been on this problem for days and now I'm close to solving if I can just get the rtmp image back on. Thanks for any further help.
