Hi I would like to use System Exec.vi with ffmpeg commands to convert a wave file from ADPCM to PCM but whatever command I give to System Exec.vi I get nothing. Could you please help me on this matter.
Attached is the vi. This vi is used to convert a wave file to pcm file . This one is also not working at all and I get 1 as return value when I enable wait until completion and 0 when I disable it
the command I used is
ffmpeg -i file.wav -f s16le -acodec pcm_s16le file.pcm
Thanks

Hi tintin_99,
Could I confirm if this command works without issue if run directly from command line without LabVIEW?
This would establish if the issue is caused by System Exec or the command being used.
