Capture stderor output?

Hi I am writting a script to do some conversions on a very large number of audio files. Using a small set of sample data I run the script and see two messages that i assume are from ffmpeg: ``` [pcm_f32le @ 000002824c7eb180] Invalid PCM packet, data has size 2 but at least a size of 8 was expected [aist#0:0/pcm_f32le @ 000002824c7a0ec0] [dec:pcm_f32le @ 000002824c7eab00] Decoding error: Invalid data found when processing input [pcm_f32le @ 000001643ca67c00] Invalid PCM packet, data has size 2 but at least a size of 4 was expected [aist#0:0/pcm_f32le @ 000001643ca20ec0] [dec:pcm_f32le @ 000001643ca67680] Decoding error: Invalid data found when processing input ``` I am doing the following in my code: ``` try: ( ffmpeg .input(original) .output( copy, acodec='pcm_s16le', ac=1, ar=16000, loglevel='error', af='aresample=osf=s16:dither_method=triangular_hp' ) .overwrite_output() # Add this to overwrite the output file .run() ) except ffmpeg.Error as ex: raise RuntimeError(repr(ex)) ``` Is tthere a way to sense/capture the message output above so that i can identify which files generated the output?
