• ffmpeg Transcoding Stops After Few Seconds [migrated]

  15 avril 2018, par Salem F

  I'm trying to do this over week now with no success, What's I'm trying to do is transcoding video from live streaming source and downscale it with FFmpeg, but every time I start transcoding it broadcasting for ~11 sec and stop.

  The last command I tried:

  ffmpeg  -re  -i 'http://source.com/1034.ts' -preset ultrafast http://localhost:2052/feed1.ffm
  

  I tried to download the .ts file with IDM and it finish downloading the file on the exact ~12 Sec that FFmpeg stop trans coding on it.

  Does that means that FFmpeg download that file as one segment and not continued reading the source video As what video players does usually. By the way, I tried with source with VLC player and it didn't stop playing the the same source video.

  I decided to pass FFmpeg command via FFserver config file ffserver.conf

  Launch ffmpeg -i 'http://source.com/1.ts' -copyinkf -codec copy   
  

  The stream works fine for a while but after testing couple sources I notice it's struggle to trans-coding HD videos.

  I guess the issue with my VPS KVM server being very limited CPU and RAM ( 128MB only)! Since I tried using ultrafast preset but din't solve the issue, another thing, I notice when I enable AVOptionVideo crf setting on ffserver.conf trans-coding runs bit smoothly without frame-rate dropping. Las my server uses Xeon L5520 CPU which is outdated CPU specially I gout 1/4 power of V single core (if they count HT it will be 1/8 of the real core): (

• Build ffmpeg static library on Mac

  15 avril 2018, par CoXier

  From guide, I can successfully compile ffmpeg on Mac. After compiling, I get a binary file ffmpeg which can be executed.

  Now I have to build ffmpeg project to a static library so that I can compile it with others c source file to a so or dylib file.

  From source code, I find ffmpeg.c and ffmpeg.h in FFmpeg/fftools/ directory and there is also a Makefile file. And its content is :

  AVPROGS-$(CONFIG_FFMPEG)   += ffmpeg
  AVPROGS-$(CONFIG_FFPLAY)   += ffplay
  AVPROGS-$(CONFIG_FFPROBE)  += ffprobe
  
  AVPROGS     := $(AVPROGS-yes:%=%$(PROGSSUF)$(EXESUF))
  PROGS       += $(AVPROGS)
  
  AVBASENAMES  = ffmpeg ffplay ffprobe
  ALLAVPROGS   = $(AVBASENAMES:%=%$(PROGSSUF)$(EXESUF))
  ALLAVPROGS_G = $(AVBASENAMES:%=%$(PROGSSUF)_g$(EXESUF))
  
  OBJS-ffmpeg                        += fftools/ffmpeg_opt.o fftools/ffmpeg_filter.o fftools/ffmpeg_hw.o
  OBJS-ffmpeg-$(CONFIG_CUVID)        += fftools/ffmpeg_cuvid.o
  OBJS-ffmpeg-$(CONFIG_LIBMFX)       += fftools/ffmpeg_qsv.o
  ifndef CONFIG_VIDEOTOOLBOX
  OBJS-ffmpeg-$(CONFIG_VDA)          += fftools/ffmpeg_videotoolbox.o
  endif
  OBJS-ffmpeg-$(CONFIG_VIDEOTOOLBOX) += fftools/ffmpeg_videotoolbox.o
  
  define DOFFTOOL
  OBJS-$(1) += fftools/cmdutils.o fftools/$(1).o $(OBJS-$(1)-yes)
  $(1)$(PROGSSUF)_g$(EXESUF): $$(OBJS-$(1))
  $$(OBJS-$(1)): | fftools
  $$(OBJS-$(1)): CFLAGS  += $(CFLAGS-$(1))
  $(1)$(PROGSSUF)_g$(EXESUF): LDFLAGS += $(LDFLAGS-$(1))
  $(1)$(PROGSSUF)_g$(EXESUF): FF_EXTRALIBS += $(EXTRALIBS-$(1))
  -include $$(OBJS-$(1):.o=.d)
  endef
  
  $(foreach P,$(AVPROGS-yes),$(eval $(call DOFFTOOL,$(P))))
  
  all: $(AVPROGS)
  
  fftools/ffprobe.o fftools/cmdutils.o: libavutil/ffversion.h | fftools
  OBJDIRS += fftools
  
  ifdef AVPROGS
  install: install-progs install-data
  endif
  
  install-progs-yes:
  install-progs-$(CONFIG_SHARED): install-libs
  
  install-progs: install-progs-yes $(AVPROGS)
      $(Q)mkdir -p "$(BINDIR)"
      $(INSTALL) -c -m 755 $(AVPROGS) "$(BINDIR)"
  
  uninstall: uninstall-progs
  
  uninstall-progs:
      $(RM) $(addprefix "$(BINDIR)/", $(ALLAVPROGS))
  
  clean::
      $(RM) $(ALLAVPROGS) $(ALLAVPROGS_G) $(CLEANSUFFIXES:%=fftools/%)
  

  Now I want to compile ffmpeg to a static library. But I am new to Makefile and it seems very hard. Can anyone help me ?

  EDIT

  I want ffmpeg.a file instead of ffmpeg binary file.

• FFMpegm. Unable to get video stream from a onvif camera

  15 avril 2018, par Denis Gottardello

  I have implemented ffmpeg in my own application to watch live video from video cameras. I have tested my application with 2 models of onvif camera and the application works perfectly. The customer has got another model of video cameram still onvif h264 but I can't watch the live stream. I can wath it using vlc but when I try to watch it with my application I obtain the following error:

  Consider increasing the value for the 'analyzeduration' and 'probesize' options
  

  I have already tried to modify analyzeduration and probesize without any good result.

  How to resolve this error? Could it be caused by a not up-to-date h264 library?

• HLS to MPEG DASH

  15 avril 2018, par Maximilian

  Im currently working on a platform that relies on MPEG Dash to deliver audio and video to the browser. For onDemand im using ffmpeg to encode videos to h264/aac and MP4Box to create the manifest.mpd file. Now im trying to figure out how to create live MPEG Dash streams, more specifically encode hls live streams to MPEG Dash.

  1. Do i need to reencode all the .ts segments to .mp4(h264/aac) segments, since chrome doesnt support mpeg2ts?
  2. If so, how do i continuously reencode all the segments (different resolution, different bitrates)
  3. How do i create a dynamic manifest with MP4Box / how would the input parameter look like
