"File descriptor in bad state" error while running ffmpeg on android device and selecting an input device
25 août 2012, par user1545779Below is the output of the ffmpeg command :# ./ffmpeg -y -f s16le -i /dev/snd/pcmC3D0c 1640.wmv -to create an audio file from a Logitech webcam on an android device.
As shown in the output, I received a File descriptor in bad state error for referring to the mic input as /dev/snd/pcmC3D0c I determined the value of the device (webcam mic) by reviewing the contents of /proc/asound. The webcam mic was card3 and its STREAM0 file indicated that the mic has an audio format of format S16_LE
It was also confirmed that it is a capture device and its' pcm id was pcmC3D0c (C3 being the card number and D0 being the Device number. I then confirmed the correct device by checking the /dev/snd/ directory to confirm its proper and full description. The /dev/snd folder confirmed that the mic was /dev/snd/pcmC3D0c
I then checked the permissions and ownership to make sure that I could use that device. Hence as far as identifying the correct device to used I do believe that /dev/snd/pcmC3D0c is the correct device. I do believe this error could possibly have something to do with the OS, however after all these checks, I still cannot figure out what is giving the bad file descriptor state error.
Please note that I tested for different output formats, etc and that did not make any difference. Any leads or suggestions ?

Pydub does not work sometimes (ffmpeg problem)
17 juillet 2022, par randomguyI'm making a program for macOS that uses pydub and therefore ffmpeg (ffmpeg was installed by copying ffmpeg and ffprobe to /usr/local/bin).


When I run my program through the terminal (python3 [filename]) or compile it into an executable file without extension, it works fine. But when I run it via IDLE or compile to .app, ffmpeg doesn't work. It says this :


RuntimeWarning: Couldn't find ffmpeg or avconv - defaulting to ffmpeg, but may not work
warn("Couldn't find ffmpeg or avconv - defaulting to ffmpeg, but may not work", RuntimeWarning)



The same message appears when ffmpeg is not installed at all.


How to make ffmpeg/pydub work correctly ?
