Hello,
Thanks for this amazing work.

Error opening './tmp/test.wav': System error.

Above error on executing python main.py --feature_type vggish --on_extraction save_numpy --device_ids 0 --video_paths ../../sample/v__N1MWv9bW6Q.mp4 --output_path ../../sample/ comand

@KPKWCE, were you able to solve this error?

hi!!! Iv fixed this issue.

The problem is because the sample mp4 file' audio is coded by acc, but our mp4 file is not.

you can try this ffprobe -v error -show_entries stream=codec_name,codec_type -of default=noprint_wrappers=1 ./sample/women_long_jump.mp4 to check out.

for me, my mp4 file is mp3.

Then i go to models/vggish/utils/utils.py
and change the line
mp4_to_acc = f'{which_ffmpeg()} -hide_banner -loglevel panic -y -i {video_path} -acodec copy {audio_aac_path}'
with
mp4_to_acc = f'{which_ffmpeg()} -hide_banner -loglevel panic -y -i {video_path} -acodec aac {audio_aac_path}'

That's ok!!!
