• Why does FFMPEG work with 1080p but doesn't work with 720p size… (code included)

  2 avril 2017, par JavaRunner

  I’ve uploaded my fully compiled code with its Makefile here :

  https://pastebin.com/xtCTj06F

  If I set 1280x720 I get the segmentation fault :

  There’s some problem with this line :

  std::cout << "sws_scale BEGIN\n";
  
  sws_scale( sws_context, ( const uint8_t * const * ) &rgb, inLinesize, 0, frame->height, frame->data, frame->linesize );
  
  std::cout << "sws_scale END\n";

  but if I set the size of a video to 1920x1080 or to 320x240 - all works fine.

  Is that some sort of a magick ?? Or a bug ?

• FFmpeg - Merge two images (.png) to video (.mp4) doesn't work

  12 juin 2019, par Jokoe

  I want to merge two images (names are not numbered in a sequence) to a video, but the result includes only a video of the first image.

  I would appreciate any kind of help !

• Could not find tag for codec h264 in stream #2 when trim video and add watermark, music background

  13 août 2020, par Nguyễn Trọng

  I'm doing cut video into chunks, then join them and add watermark and background music with the command below.

  


  "[-y, -i, /storage/emulated/0/WhatsApp/Media/WhatsApp Video/VID-20200726-WA0154.mp4, -i, /storage/emulated/0/FXMotion/.cache/.watermark/logo_watermark.png, -stream_loop, -1, -i, /storage/emulated/0/WhatsApp/Media/WhatsApp Documents/DripReport_-_Skechers_(Lyrics)(MP3_160K).mp3, -filter_complex, [1:v]scale=640/4:-1[logo1];[0:v]trim=0:2.483,setpts=PTS-STARTPTS[v1];[0:v]trim=2.483:7.45,setpts=2.0*(PTS-STARTPTS)[v2];[0:v]trim=7.45:9.933,setpts=PTS-STARTPTS[v3];[v1][v2][v3]concat=n=3:v=1[video];[video][logo1]overlay=main_w-overlay_w-10:main_h-overlay_h-10[vw], -map, [vw], -map, 2, -c:v, libx264, -crf, 23, -preset, veryfast, -shortest, /storage/emulated/0/FXMotion/FXMotion-200810e.mp4, -hide_banner]"
