• Can ffmpeg read-only options be used via the command line ?

  13 juin 2024, par Quppa

  For example, ffmpeg's ebur128 filter has read-only (AV_OPT_FLAG_READONLY) export (AV_OPT_FLAG_EXPORT) options integrated, range, lra_low, lra_high, sample_peak and true_peak (source).

  


  Is there a way to get the output values for filter options like these when using the command line ?

  


  My command line :
ffmpeg -i test.mp3 -af ebur128=integrated:framelog=quiet -f null -

  


  Output (ffmpeg 7.0.1) :

  


  [Parsed_ebur128_0 @ 000001e0c2f27880] Unable to parse option value "integrated" as boolean
Error applying option 'video' to filter 'ebur128': Invalid argument
[aost#0:0/pcm_s16le @ 000001e0c2f26a40] Error initializing a simple filtergraph

• h265_videotoolbox for Apple Chips Not working with ffmpeg

  22 janvier 2024, par Martin Julien

  I have a 16-inch Macbook Pro.
System :
Model Name : MacBook Pro
Chip : Apple M1 Max
Total Number of Cores : 10 (8 performance and 2 efficiency)
Memory : 64 GB

  


  You can take advantage of apple chips to encode faster by replacing the usual line :
-c:v libx265 by -c:v h265_videotoolbox.

  


  Here's an example.
Since h265 doesn't work at the moment, here's a line that works just fine :

  


  for i in *.mp4; do ffmpeg -i "$i" -c:v h264_videotoolbox -b:v 2000k -c:a aac -b:a 192k -s 1920x1080 -threads 8 "${i%.*}_1.mp4"; done

  


  The version of ffmpeg installed on my mac is the latest : 6.1.1

  


  My problem :
I want to encode in h265. My command line is :
for i in *.mp4; do ffmpeg -i "$i" -c:v h265_videotoolbox -b:v 2000k -c:a aac -b:a 192k -s 1920x1080 -threads 8 "${i%.*}_1.mp4"; done

  


  Everything should work in theory. But I get this from the Shell :

  


  [vost#0:0 @ 0x150f06fd0] Unknown encoder 'h265_videotoolbox' [vost#0:0 @ 0x150f06fd0] Error selecting an encoder Error opening output file Denis_1.mp4. Error opening output files: Encoder not found

  


  My attempts :

  


  I spent a lot of time with ChatGPT to solve the problem, but nothing worked. So I'm asking the question here to see if anyone has had the same problem as me and if there's a solution to fix it.

  


  Thank you for your help,

  


  best regards,
Martin
