• How to get stream info from opened file in ffmpeg ?

  31 mai 2013, par Srv19

  I am trying to read video file using ffmpeg. I had working code that corresponded to somewhat old version of it, and started to try and upgrade to latest build version, exchanging all those deprecated functions for their actual analogues.

  However i have run into a problem. No streams seem to be retrieved and the load of video stops dead in tracks.

  here is the code i am using :

     // Open video file
  
     if(avformat_open_input(&pFormatCtx, filename.toStdString().c_str(), NULL, NULL)!=0)
  
         return FILE_NOT_OPENED; // Couldn't open file
  
  
  
     // Retrieve stream information
  
     if(avformat_find_stream_info(pFormatCtx,NULL)<0)
  
         return NO_STREAM_INFO; // Couldn't find stream information
  
  
  
     // Dump information about file onto standard error
  
     av_dump_format(pFormatCtx, 0, filename.toStdString().c_str(), false);
  
  
  
     // Find the first video stream
  
     videoStream=-1;
  
     for(unsigned i=0; inb_streams; i++)
  
         if(pFormatCtx->streams[i]->codec->codec_type==ffmpeg::AVMEDIA_TYPE_VIDEO)
  
         {
  
             videoStream=i;
  
             break;
  
         }
  
     if(videoStream==-1)
  
         return OTHER; // Didn't find a video stream
  
  
  
     // Get a pointer to the codec context for the video stream
  
     pCodecCtx=pFormatCtx->streams[videoStream]->codec;
  
  
  
     // Find the decoder for the video stream
  
     pCodec=avcodec_find_decoder(pCodecCtx->codec_id);
  
     if(pCodec==NULL)
  
         return CODEC_NOT_FOUND; // Codec not found
  
  
  
     // Open codec
  
     if(avcodec_open2(pCodecCtx, pCodec,NULL)<0)
  
         return CODEC_NOT_OPENED; // Could not open codec

  The problem arises in the cycle through video streams in ffmpeg::AVFormatContext *pFormatCtx. nb_streams field is 0, and i never actually enter the cycle, and codec is not loaded etc. Strange thing is, av_dump_format gives following output :

  and there are 2 streams, clear as day.

  I am utterly baffled. Please help.

  At this step I have two problems :
  first is a warning during execution
  deprecated pixel format used, make sure you did set range correctly
  The second is the video do not work correctly in VLC (video is "black") but it work in wmp...
  

  Then I add an empty audio track :

  ffmpeg -threads 8 -f lavfi -i aevalsrc=0 -i "D:\Records\2013-10-11_115453\PublishingDirectory\Temporary_WithtoutAudio1.mp4" -vcodec copy -b:v 1500k -acodec aac -map 1:0 -map 0:0 -shortest -strict experimental -y "D:\Records\2013-10-11_115453\PublishingDirectory\Temporary1.mp4"

  After that I concat this video to others using complex filter .
  When I concat my videos I have this message :
  

  [output stream 0:1 @ 0451d3a0] 100 buffers queued in output stream 0:1, something may be wrong.

  And when i Watch the result my video freeze after the image insertion for a approximatly a seconde .
  perhaps it is not related
  I don't know ...

  Here my concat command and execution log
  

  D:\test>ffmpeg.exe -threads 8 -i "D:\Records\2013-10-11_115453\PublishingDirectory\Temporary0.mp4" -i "D:\Records\2013-10-11_115453\PublishingDirectory\Temporary1.mp4" -i "D:\Records\2013-10-11_115

  So How can I Fix my "picture" video ?
  Will it fix the freeze problem after concatenation of videos ?
  If not How can I fix it ?
  

  Thanks in advance !
  

• DASH package (mpd) I made freezes after raising the onratechange event

  7 mars 2016, par Nick Birke

  I am trying to created an adaptive stream from an mp4 file. I have a decent amount of experience at doing streaming, and have successfully implemented smooth streaming via Silverlight. We want a solution for everything that works in HTML5. I am pursuing DASH. So here are the steps I take...

  1. Resample the mp4 to different sizes using ffmpeg.
  2. Ensure the files are properly fragmented using Bento4s mp4Fragment utility.
  3. Create the DASH mpd file and associated segments using Bento4s mp4dash utility.

  I have done a lot of work to learn each of these utilities and create a process that gets to output that I think will work. To create reliable DASH artifacts. But it seems I am doing something wrong. Here are examples of command lines I run.

  For step one I create three different files... for three different rates and sizes... (these may not be the exact command lines, they are from old notes... but the parameter values are the ones I am using for sure)

  ffmpeg -y -i C:\_SIMULATED_SHARE_C\ff\big_buck_bunny.mp4 -c:v libx264 -x264opts keyint=24:min-keyint=24:no-scenecut -b:v 1500k -maxrate 1500k -bufsize 1000k -vf "scale=-1:720" C:\_SIMULATED_SHARE_C\ff\output\outputfile720.mp4
  
  
  
  ffmpeg -y -i C:\_SIMULATED_SHARE_C\ff\big_buck_bunny.mp4 -c:v libx264 -x264opts keyint=24:min-keyint=24:no-scenecut -b:v 800k -maxrate 800k -bufsize 500k -vf "scale=-1:540" C:\_SIMULATED_SHARE_C\ff\output\outputfile540.mp4
  
  
  
  ffmpeg -y -i C:\_SIMULATED_SHARE_C\ff\big_buck_bunny.mp4 -c:v libx264 -x264opts keyint=24:min-keyint=24:no-scenecut -b:v 400k -maxrate 400k -bufsize 400k -vf "scale=-1:360" C:\_SIMULATED_SHARE_C\ff\output\outputfile360.mp4

  So that gives you the three files that need to be fragmented. So I fragment them using the mp4fragment utility from Bento4. That command line is simple so I will not offer an example.

  The I use Bento4s mp4dash to create the dash. Something like this...

  "E:\\_INSTALL\\Bento4\\Bento4-SDK-1-4-3-607.x86-microsoft-win32-vs2010\\Bento4-SDK-1-4-3-607.x86-microsoft-win32-vs2010\\bin\\mp4dash.exe --mpd-name=\"\\\\d9fqt52\\_SIMULATED_SHARE_C\\ff\\output\\dash\\something.mpd\" -f -o \"\\\\d9fqt52\\_SIMULATED_SHARE_C\\ff\\output\\dash\" \"\\\\d9fqt52\\_SIMULATED_SHARE_C\\ff\\output\\bunny360f.mp4\" \"\\\\d9fqt52\\_SIMULATED_SHARE_C\\ff\\output\\bunny540f.mp4\" \"\\\\d9fqt52\\_SIMULATED_SHARE_C\\ff\\output\\bunny720f.mp4\" "

  This runs ok. And creates the mpd file, an audio folder with segment files, an a video folder with 3 folders each with the segment files.

  I am able to configure IIS to play the mpd ok. As well as the segement files. The video plays fine... and then it stops. It freezes between 50 and 60 seconds. Right before it freezes I can confirm that the onratechange event of the HTML5 video tag is raised. This is an event that is raised with the rate of play is changed. I do nothing to change this it just happens.

  The actual video in question is about 1hr long. Also I am using the dash.js library as a player.

  If you can identify any components or specifics I should change please let me know !
