• ffmpeg nvdec not available when adding subtitles to mp4

  17 février 2019, par whatdoineed2do

  I have a mp4 video that I want to BURN-IN subtitles (from a .ass file and via -vf ass=/tmp/conf-notes.ass) with ffmpeg on a machine with a GTX1060 card however ffmpeg reports that it fails to create the NVDEC decoder.

  [h264 @ 0xcb9380] Error creating a NVDEC decoder: 1
  
  [h264 @ 0xcb9380] Failed setup for format cuda: hwaccel initialisation returned error.

  The output file is generated ok but during the creation the CPU is used heavily (I assume for decode) - if I drop the -vf ass=/tmp/conf-notes.ass and perform an mp4->mp4 reencode there are no problems.

  I want to know what I am missing from my command to allow the GPU to perform the decode when an .ass file is added to the chain.

  $ ffmpeg -hwaccel cuvid -i 2019-01-conferance.mp4 -vf ass=/tmp/conf-notes.ass -c:a copy -preset llhq -rc vbr_hq -vb 2M -minrate 500k -maxrate 12M -c:v h264_nvenc export.mp4

  This issue does not appear if I remove —enable-pocketsphinx from the configure argument.

  I built and installed sphinxbase from the source, and I used macport’s pocketsphinx version because building from source failed. These two issues might be related.

• W/System.err : java.lang.Exception : FFmpeg not loaded

  1er juillet 2021, par numa

  I ran an android machine learning code that uses AndroidAudioConverter from https://github.com/adrielcafe/AndroidAudioConverter, but I got the different errors as following.
  

  


  When I ran it with AVD emulator, it said (the error is in red font) :

  I used the Android 10 smartphone and Android 9 for AVD. This is a team project, which my friend build. It can run on his smartphone (Android 9). I need to connect the program to the cloud storage but I don't know why it ain't running on my device or emulator.
  
If anyone knows how to resolve this issue please help.
  
Thanks.
