• FFMpeg hello world failed

  13 mai 2014, par xorange

  I’m new to the ffmpeg development.

  I’ve got my ffmpeg via ffmpeg.mplayerhq.hu/download.html using

     `git clone git://source.ffmpeg.org/ffmpeg.git ffmpeg`

  My OS is Win7. I’m using Cygwin to help me work under a Unix-like environment.

  I’m using tutorial code from http://dranger.com/ffmpeg/ffmpeg.html. My current code is Tutorial01.

  So I’ve got my gcc, ffmpeg and code together. Working directory is /ffmpegDemo,

  code : /ffmpegDemo/tutorial01.c

  ffmpeg : /ffmpegDemo/ffmpeg

  And I use command gcc-I ffmpeg -o t01 tutorial01.c to compile my code.
  (cygwin doesn’t support "copy", here’re just some major message :)

  libavutil/avconfig.h : No such file or directory

  ...

  error : ’CODEC_TYPE_VIDEO’ undeclared

  ...

  and others are just warnings.

  Indeed, there’s no avconfig.h under ffmpeg/libavutil. I’ve looked for ’CODEC_TYPE_VIDEO’, here’s this reference : http://cekirdek.pardus.org.tr/ ismail/ffmpeg-docs/avcodec_8h.html says that ’CODEC_TYPE_VIDEO’ is defined in libavcodec/avcodec.h. I’ve checked avcodec.h and didn’t find any.

  I was very confused about this error and confused about all the "configure" and "make" things that I saw while searching for answer. Am I doing it wrong ? Did I miss some steps ? Hope that I could find an answer here.

  Thanks.

• Laravel ffmpeg failed to execute command

  I'm using protonemedia/laravel-ffmpeg package everything works fine on localhost but on the live server, there is an error message shown.

  I'm using a job to do conversation

  


  ConvertVideoForStreaming.php Job :

  


  <?php

        $this->video->update([
            'converted_for_streaming_at' => Carbon::now(),
        ]);
    }
}


  


  I'm storing the key at custom disk "streamable_keys", and converted videos should be stored in "streamable_videos".

  


  the streamable keys are generated and saved to a directory without any issues, but streamable videos are not saved to the directory.

  


  after some tracks I found that the problem happens in this line of code :

  


          ->save($this->video->id . '.m3u8');


  


  all the lines before that line work perfectly.

  


  any ideas on how to fix that ?

• Conversion failed. 2 frames left in the queue on closing ffmpeg

  28 août 2020, par AlexZheda

  My simplified ffmpeg command (the longer one has over 300 files) is the following.

  



  ffmpeg -i "v1.mp4" -i "v2.mp4" -i "v3.mp4"
    -filter_complex "[0:v:0][1:v:0][2:v:0]concat=n=3:v=1:a=0,fps=fps=30[cv1]; 
        [0:a:0][1:a:0][2:a:0]concat=n=3:v=0:a=1,asetpts=N/SR/TB[ca1]; 
        [cv1]setpts=0.25*PTS[v4]; 
        [ca1]atempo=4,asetpts=N/SR/TB[a4]" 
    -c:v h264_nvenc -map "[v4]" -map "[a4]" x4_output_0.mp4


  



  The video encoding is working but then breaks and the output file seems to be truncated. The output files are nearly of the size as they should be but they can't be read.

  



  Video encoding failed\r\n
[aac @ 00000248a7856840] Qavg: 325.600\r\n

Conversion failed!\r\n")


  



  

  1. Does the error have anything to do with the audio part of .mp4 since aac @ ... ?

  


  2. What does the Qavg mean in the error message ?

  


  3. What is the difference in the video stream between the codec_time_base and the time_base (see the differences in the video attributes frequencies below) ?

  


  



  Below are the frequencies of the video attributes for all videos that have more than 1 distinct value. It's of the form [(value, frequency), (value, frequency),...].

  



  codec_time_base --- [('1/60', 384), ('1001/60000', 7), ('50/2997', 1)]
has_b_frames --- [(0, 336), (2, 56)]
level --- [(31, 336), (30, 56)]
r_frame_rate --- [('30/1', 384), ('30000/1001', 7), ('2997/100', 1)]
avg_frame_rate --- [('30/1', 384), ('30000/1001', 7), ('2997/100', 1)]
time_base --- [('1/30', 383), ('1/30000', 7), ('1/2997', 1), ('1/15360', 1)]


  



  The same for the audio attributes in all those video files.

  



  codec_time_base --- [('1/48000', 386), ('1/44100', 6)]
sample_rate --- [('48000', 386), ('44100', 6)]
time_base --- [('1/48000', 386), ('1/44100', 6)]


  



  

  4. Is it possible that something is not right with some of the video files here that causes the breakdown of the encoding ?
