• ffmpeg doesnt use all the pictures when creating a video

  9 septembre 2022, par Mikhael Karabas

  I have 75 pictures of the same size for an animation. named 0.png ... 74.png
when running ffmpeg to create a video out of them with 24 fps (commmand and log below) the resulting video instead of expected 75/24 = 3.125 sec. is 2.667 sec in lenght and consists only of first 64 frames(pictures), although ffmpeg tells it has processed 75 frames.
I have checked with

  


  ffmpeg -i output.webm out%%d.png - on the resulting video, it indeed exports 64 first frames and not the rest 11 of them.

  


  Cant undertand what am i doing wrong. please kindly advise.

  


  brief output below.

• ffmeg, missing size : Could not find codec parameters for stream 0 (Video : exr, gbrapf32le)

  13 septembre 2022, par RobertSmith

  I’m getting an error message using ffmpeg on Windows (a newer version of ffmpeg from 2022) using exr files. I'm trying to convert the exr to a video. However, I can get the error with just the command below :

  


  ffmpeg.exe -analyzeduration 9223372036854775807 -probesize 9223372036854775807 -i test_501_030_075_cg_testing_v001.1001.exr


  


  Below is the error :

  


  [exr @ 0000026319944c00] Unsupported channel VRayVelocity.Y.
[exr @ 0000026319944c00] Unsupported channel VRayVelocity.Z.

Consider increasing the value for the 'analyzeduration' (9223372036854775807) and 'probesize' (9223372036854775807) options
Input #0, exr_pipe, from 'X: Test_501_030_075_cg_testing_v001.1001.exr':
  Duration: N/A, bitrate: N/A
  Stream #0:0: Video: exr, gbrapf32le, 25 fps, 25 tbr, 25 tbn


  


  When converting to a video, I also got :

  


  2022-09-12 10:39:36:  0: [buffer @ 000001402775ee80] Unable to parse option value "0x0" as image size
2022-09-12 10:39:36:  0: [buffer @ 000001402775ee80] Error setting option video_size to value 0x0.


  


  I'm not sure what's wrong ? I can open the EXR itself. We've also used ffmpeg fine on a bunch of other exrs (which also got those errors about unsupported channels like VRayVelocity, but ffmpeg worked just fine).
I believe I have set analyzeduration and probsize to the highest values allowed ( MaxInt64).

  


  Anyone have any ideas/suggestions ? Thanks !

  


  P.S. If people need more info here, please let me know what info specifically might be helpful. I have done research on this question (setting analyzeduration to highest setting for example) I'm posting here because I'm lost as what to try next and wondering if people have had similar issues

  


• Jellyfin ffmpeg permission denied

  11 septembre 2022, par Steve

  I am running Jellyfin on a Raspberry Pi 4 in a docker container (https://hub.docker.com/r/linuxserver/jellyfin) and am trying to set up hardware accelerated video transcoding. I'm fairly certain I have set up the video devices & permissions correctly, but I am getting the following exception in the logs when trying to play a video through the web interface :

  The real head-scratcher is that if I log in to the docker container with docker exec -it  /bin/bash and paste the ffmpeg command from the logs and run it, it works fine.

  


  I'm running as the jellyfin user, which is in the video group, and has read/write access to the media directory.

  


  Any thoughts ?

  


  My docker-compose file is attached below, if any other system information is needed let me know.
