• ffmpeg runs in terminal but returns error in subprocess.run from flatpak-installed pycharm

  19 juin 2024, par name

  I want to run this command in python :

  


  ffmpeg -ss 00:00:30 -i "/home/exl/—1—ARCHIVE—1—/video/music videos/author --- a2 - name (text).webm" -vf scale=150:-2 -vframes 1 -c:v libwebp -compression_level 6 -quality 100 /home/exl/—1—ARCHIVE—1—/—3—previews—3—/734a8a0bac3a83e0f6c69416a26ec5cd211a6d742f3df63bb72bdbe6431b57c30677bc11551ba4aaaecac15ed2c48de51340a09020b7e9d9479e1e81ff766191.webp


  


  In terminal it works fine, but in subprocess returns error. Python code :

  


  finished_process = subprocess.run(
                    [
                        '/usr/bin/ffmpeg',
                        '-ss', f'00:00:{seconds_shift}',
                        '-i', original_path,

                        '-vframes', '1',
                        '-c:v', 'libwebp',
                        '-compression_level', '6',
                        '-quality', '100',
                        preview_path
                    ],
                    #stdout=subprocess.DEVNULL,
                    #stderr=subprocess.DEVNULL,
                    check=False,

                )

  As suggested here (FFMPEG command runs in terminal but not by subprocess) i tried using which determine path to correct version, but this command returns /usr/bin/ffmpeg both in python and in terminal.

  


  which ffmpeg (both subprocess.run(['which', 'ffmpeg'], capture_output=True).stdout and terminal) : /usr/bin/ffmpeg

• FFmpeg unable to save file on Android : Output file #0 does not contain any stream

  16 mai 2022, par John M.

  I'm having difficulty when saving a RTSP stream into internal storage using ffmpeg-kit -i rtsp://192.168.100.60:554/stream1 -c:v copy -c:a copy -t 5 /data/user/0/com.arthenica.ffmpegkit.test/files/test.mp4. The command is called using FFmpegKit.executeAsync(command, ...). There're issues with the circular_buffer_size option, but I read that the warnings could be ignored. The command runs fine on desktop using ffmpeg. Please find below the log.

  


  Any advice would be appreciated.

• lavc/riscv : depend on RVB and simplify accordingly

  27 juillet 2024, par Rémi Denis-Courmont

  lavc/riscv : depend on RVB and simplify accordingly
  There is no known (real) hardware with V and without the complete B
  
  extension. B was indeed required in the RISC-V application profile from
  
  2022, earlier than V. There should not be any relevant hardware in the
  
  future either.
  In practice, different R-V Vector optimisations in FFmpeg already depend on
  
  every constituent of the B extension anyhow, so it would not work well.
