• FFMEPG crop : Invalid too big or non positive size for width '1920' or height '1040'

  12 février 2021, par NatePhysics

  I run into a strange issue with a particular file in FFMPEG. When I try and crop it down a little I get :

  


  [Parsed_crop_0 @ 000002ad60c27980] Invalid too big or non positive size for width '1920' or height '1040'
[Parsed_crop_0 @ 000002ad60c27980] Failed to configure input pad on Parsed_crop_0
Error reinitializing filters!
Failed to inject frame into filter network: Invalid argument
Error while processing the decoded data for stream #0:37
Conversion failed!


  


  This is odd to me because you can even see from the stream metadata that the resolution is much higher :

  


  Metadata:
    encoder         : libebml v1.4.0 + libmatroska v1.6.2
    creation_time   : 2021-02-09T22:45:47.000000Z
  Duration: 02:17:48.93, start: 0.000000, bitrate: 8548 kb/s
    Stream #0:0: Video: h264 (High), yuv420p(progressive), **1920x1080** [SAR 1:1 DAR 16:9], 23.98 fps, 23.98 tbr, 1k tbn, 47.95 tbc (default)


  


  There's only 1 video stream. I'm running the following command :

  


  ffmpeg -i "wedding.mkv" -filter:v "crop=1920:1040" -c:v libx264 -preset slow -tune film -profile:v high -level 4.1 -crf 19 -c:a copy -c:s copy -map 0 "wedding-cropped.mkv"


  


  I can preview the crop using the following command without any errors :

  


  ffplay -i "wedding.mkv" -vf "crop=1920:960"


  


  I've cropped a few files before without issue. I'm a bit confused as to why I'm getting a resolution error in this case when the video file is clearly higher resolution. I've also tested lowering the cropped resolution and even when I lower both by several hundred pixels it still spits out the same error. Any thoughts or suggestions ?

  


• mkv video from raw png pictures16 bit depth using ffmpeg

  9 novembre 2023, par Jake

  I need to receive video with this output

  


  


  Stream #0:1(eng) : Video : rawvideo (b16g / 0x67363162), gray16be,
640x576, SAR 1:1 DAR 10:9, 30 fps, 30 tbr, 1000k tbn, 1000k tbc
(default)

  


  private data :

  


  size 40(FourCC : 0x62313667 "b16g")

  


  


  I am trying to use :

  


  ffmpeg.exe -i depth%d.png -c:v rawvideo -vtag b16g -pix_fmt gray16be -r 30 -allow_raw_vfw 1 depth_out.mkv


  


  but i received video with those parametres :

  


  


  Stream #0:0 : Video : rawvideo, rgb555le, 640x576, SAR 1:1 DAR 10:9, 30
fps, 30 tbr, 1k tbn, 1k tbc (default)

  


  and with this private codec data :

  


  size 40(FourCC : 0x00000000 " ????" : Uncompressed)

  


  


  I would appreciate any advice or guesses, thanks !

• AWS MediaConvert fails when transcoding a video created from an iOS Safari WebRTC

  18 février 2021, par Node.JS

  I am trying to transcode a video using MediaConvert and I get the following error :

  


  


  Error message Demuxer : [ReadPacketData File read failed - end of file
hit at length [1105924]. Is file truncated ?]

  


  


  When I try to run ffmpeg command to get information about the file I see this :

  


  


  non monotonically increasing dts to muxer in stream

  


  


  I am wondering is there a configuration in MediaConvert that can correct the time stamps ?
