• FFMPEG crash while cropping video

  18 octobre 2022, par Khawar Raza

  I am using FFMPEG to crop a video. I am using ffmpeg-kit as a ffmpeg wrapper in my android app where the user can select any output size irrespective of the original video aspect ratio. Below is the problematic command :

  


  -i "/storage/emulated/0/Download/83a2f6_1080p~2.mp4" -filter_complex "[0:v]crop=304:236:2:2[cropped]" -map "[cropped]" "/storage/emulated/0/DCIM/appname/vid_d8ee328d-ec7a-468b-9313-4561dceea33e.mp4"


  


  When the execution starts, the application crashes.

  I don't know what is wrong with the output width and height parameters. If I change [0:v]crop=304:236:2:2[cropped] to [0:v]crop=304:304:2:2[cropped] with change in height, the process completes successfully. The original video (1080x808) is not smaller than the output size. It does not seem to be a problem in the video as I have tried different videos. Any tips on what is missing from my command ?

  


• Invalid data error during ffmpeg .m4a conversion

  4 janvier 2023, par Kazi bácsi

  I wanted to edit my .m4a voice recording from Samsung Voice Recorder using ffmpeg 2.2.2, however, I got the error Invalid data found when processing input. I tried to open it through Audacity, but it returned an error claiming that the ffmpeg library is missing, which is definitely not the case. Eventually I tried to use online .m4a to .mp3 converters, but they all returned error, so I assume there may be an issue with the encoding of the original file and ffmpeg should be configured accordingly. What settings shall I use ? (The original file can be played on the phone without any problem.)

• Video encoder & segmenter for HLS VoD poor quality

  10 juillet 2017, par Murilo

  I am trying to encode and segment video for HLS on demand(VoD).
  I am using the following code for such :

  ffmpeg -i 20170706_174314.mp4 -c 24 \
  
          -vcodec libx264 -acodec aac -ac 1 -strict -2 -b:v 128k \
  
          -profile:v baseline -maxrate 400k -bufsize 1835k \
  
          -hls_time 10 -hls_playlist_type vod -vsync 1 \
  
          video_chunks/index1.m3u8 \
  
          -c 24 -vcodec libx264 -acodec aac -ac 1 -strict -2 -b:v 128k \
  
          -profile:v baseline -maxrate 700k -bufsize 1835k \
  
          -hls_time 10 -hls_playlist_type vod -vsync 1 \
  
          video_chunks/index2.m3u8

  I tried this other code also just for segmenting but had the same exactly problem :

  ffmpeg -i 20170706_174314.mp4 \
  
  -c:a libmp3lame -ar 48000 -ab 64k  -c:v libx264 -b:v 128k -flags \ 
  
  -global_header -map 0 -f segment \
  
  -segment_list video_chunks/test.m3u8 -segment_time 10 -segment_format mpegts \
  
  video_chunks/segment_%05d.ts

  Later on I create another playlist with bandwidth separators to call on the two other playlists generated with the code above.

  This code was working great on some videos but yesterday I recorded a video with my Samsung J7 Prime phone to test since the videos will be generated by phone and this video was poorly encoded. The quality sucks and some parts of the video turned Black&White.

  Another thing I noticed on this video is that the following message kept appearing in loop until the end of the encoding&segmenting process.

  Past duration X too large

  Where X is a decimal really close to

  0.675316
