Keeling, William via Libav-user (HE12026-05-22): > I have an issue of avformat_open_input() returning -3 “No such > process” on call to open a pulse audio source. The code works on > older Pi OS with larger memory.
The error message “No such process” is a bug in the Pulse module of FFmpeg, you can report it: In pulse_audio_dec.c, pulse_read_header() returns AVERROR(pa_context_errno(pd->context)), but despite the name, pa_context_errno() does not return a errno value compatible with system error codes. > avformat_open_input() ps is nullptr, url is "plughw:RacecamMic" that > works for arecord, fmt is the AVInputFormat pointer found by > av_find_input_format() to "pluse' and options is nullptr I would suggest to use the Pulse command that lists the devices available on the system. Also, check if you really wrote pluse in the program and not just in the mail.
