How to get stream info from opened file in ffmpeg ?
31 mai 2013, par Srv19I 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 codecThe 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 :License: GPL version 3 or later
AVCodec version 3606372

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

DASH package (mpd) I made freezes after raising the onratechange event
7 mars 2016, par Nick BirkeI 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...
- Resample the mp4 to different sizes using ffmpeg.
- Ensure the files are properly fragmented using Bento4s mp4Fragment utility.
- 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.mp4So 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 !
