• Concatenating on Windows throws "Invalid data found when processing input" while it works on Mac and Linux

  15 février 2020, par miguelmorin

  I need to run a command with a nightly build of FFMPEG to report a bug on the concat protocol. I found it difficult to compile from source with libx264 support on Linux, and I want to spare my Mac computer, so I use the nightly build on Windows from Zeranoe.

  I call this command to concatenate the files :

  ffmpeg -safe 0 concat -i files_to_combine -vcodec libx264 show.mp4

  where files_to_combine is :

  file ./short_DSC_0013.MOV
  
  file ./short_DSC_0014.MOV
  
  file ./short_DSC_0015.MOV
  
  file ./short_DSC_0016.MOV
  
  file ./short_DSC_0017.MOV
  
  file ./short_DSC_0018.MOV
  
  file ./short_DSC_0019.MOV

  I call this command from the directory containing the video files and files_to_combine.

  On Windows with a nightly build, I get the error :

  files_to_combine : Invalid data found when processing input
  

  I changed file ./DSC_0013.MOV to these options, all with the same error :

  file 'short_DSC_0013.MOV'
  
  file '.\short_DSC_0013.MOV'
  
  file 'F:\short_DSC_0013.MOV'

  How can I debug this error, or what is the syntax for concatenating on Windows with a nightly build ?

  Update with log-level 48

  I ran the same command with -v 48 and got :

  F :\brain squids>C :\Users\migue\Desktop\ffmpeg-20200211-f15007a-win64-static\bin\ffmpeg.exe -v 48 -i files_to_combine -vcodec libx264 show.mp4

  Update because of wrong command

  I had mistyped the command. The right command has a -f in front of concat, which I found because the accepted answer was able to make the command work in a similar environment :

  ffmpeg -safe 0 -f concat -i files_to_combine -vcodec libx264 show.mp4

• How to fix EXT-X-MAP:URI in m3u8 when specifying absolute hls_fmp4_init_filename using ffmpeg ?

  29 février 2020, par Ryan

  Today I found this blog post teaching me about fragmented mp4s (fmp4s).

  Using the ffmpeg docs, I’ve made great progress.

  I run this :

  '/usr/bin/ffmpeg' '-y' '-i' '/myproject/storage/app/sample_media/2020-02-27/Sample Videos 5.mp4' \
  
  '-c:v' 'libx264' '-s:v' '1920x1080' \
  
   '-crf' '20' '-sc_threshold' '0' '-g' '48' '-keyint_min' '48' \
  
  '-hls_list_size' '0' '-hls_time' '10' '-hls_allow_cache' '0' '-b:v' '4889k' \
  
  '-maxrate' '5866k' '-hls_segment_type' 'fmp4' \
  
  '-hls_fmp4_init_filename' '/myproject/public/storage/000000002/init.mp4' \
  
  '-hls_segment_filename' '/myproject/public/storage/000000002/list_1080p_%04d.m4s' \
  
  '-hls_key_info_file' '/myproject/hls_hls.keyInfo' '-strict' '-2' '-threads' '12' \
  
  '/myproject/public/storage/000000002/list_1080p.m3u8'

  And then I use hls.js on my webpage to try to show the video.

  Initially, it won’t load.

  But then I can get the video to load properly if I refresh the page after making this edit to list_1080p.m3u8 :

  Change from :

  #EXT-X-MAP:URI="/myproject/public/storage/000000002/init.mp4"

  To :

  #EXT-X-MAP:URI="init.mp4"

  How can I change my ffmpeg command so that it knows the absolute path of where to save the init.mp4 but also knows to write in the m3u8 only the filename init.mp4 without any path ?

  (I’ve tried using -hls_fmp4_init_filename init.mp4 without the abosolute path, but then it creates the init.mp4 at the root, which also doesn’t work. I need each video’s init.mp4 to be in its own folder.)

• ffmpeg faster conversion from jpg files to mp4

  25 mai 2021, par opensw

  I am trying (on Android and iOS) to convert 500 jpeg files into a mp4 video ; everything is working but the conversion time is too huge, around 1 minute. I have some constraints : the video should be playable by the native Android/iOS player then I cannot use the option '-codec copy' and then generates a mkv or mp4 containers of the original jpeg files (the conversion time in this case is around 1s !). After many attempts, the best solution is the default one without almost any options :D Is there a way to improve the conversion time of the following command ?

  


  ffmpeg -r 30 -I inputPath/%05d.jpg -y -threads 0 -r 30 + outputFilePath.mp4


  


  I have tried :

  


  

  1. -q:v 2 (but I would like to keep the original resolution, it is slower than the above command)

  


  2. -vf scale=-2:720 (but I would like to keep the original resolution, it is comparable to the above command)

  


  3. -s hd720 (but I would like to keep the original resolution, it is comparable to the above command)

  


  4. -threads 128 (does not change anything)

  


  5. -c:v libx264 -crf 23 -preset ultrafast, this one is painfully slow
