Currently, FFmpeg requires an exact match of the audio input device name
when specifying an input device (e.g., with -f dshow -i audio="Device
Name" on Windows). This can be inconvenient when device names are long or
change slightly between systems.
Proposed Enhancement:
Introduce support for partial matching of device names, so users can
provide a substring instead of the full, exact name.
For example:
ffmpeg -f dshow -i audio="microphone" ...
Implementation Suggestion:
In the code that matches input device names, the comparison currently uses
strcmp in dshow.c
{{{
if (pfilter) {
if (strcmp(device_name, friendly_name) && strcmp(device_name,
unique_name))
goto fail;
}}}
This could be replaced with a substring match using strstr:
{{{
if (pfilter) {
if (!strstr(friendly_name, device_name) && !strstr(unique_name,
device_name))
goto fail;
}
}}}
It might be worth considering implementing some form of case-insensitive
comparison.
Thank you.
