#4486: Missing AVInputFormat.get_device_list() for dshow and avfoundation
----------------------------------+--------------------------------------
Reporter: nalply | Type: defect
Status: new | Priority: normal
Component: avdevice | Version: git-master
Keywords: | Blocked By:
Blocking: | Reproduced by developer: 0

----------------------------------+--------------------------------------
Rationale: We are writing a C library to enumerate devices
programmatically.
Currently one can pass the option -list_devices to the ffmpeg executable
and this is handled in libavdevice/dshow.c:dshow_read_header() and
libavdevice/avfoundation.m:avf_read_header(), but this is not accessible
by API (we get "function not implemented" when invoking
avdevice_list_devices()).
Would it make sense to separate this code out to a separate function
dshow_get_device_list() and assign it to ff_dshow_demuxer.get_device_list?
Similarly for avfoundation?
Should we go ahead and then mail a patch or a git merge proposal to
ffmpeg-devel?
