How to parse ffmpeg -list_options output to get complete list of formats ?
9 octobre 2024, par gaamaaOn my Windows 10, application I use VB6 and ffmpeg.exe to capture video from USB capture device.
I need to show complete list of supported formats by this capture card.


When I use below command I get some list.
But its looks incomplete for me.



 ffmpeg -f dshow -list_options true -i video="USB3. 0 capture"



Result :


USB3. 0 capture:
 Q:\FFMpeg VB6\f2>ffmpeg -f dshow -list_options true -i video="USB3. 0 capture"
[dshow @ 087d7480] DirectShow video device options (from video devices)
[dshow @ 087d7480] Pin "Capture" (alternative pin name "0")

pixel_format=yuyv422 min s=640x480 fps=5 max s=640x480 fps=30


My question is :


How to get the proper list in-between min and max ?


Eg :
Please see the below 4 lines.


vcodec=mjpeg min s=1920x1080 fps=10 max s=1920x1080 fps=60.0002
 vcodec=mjpeg min s=1920x1080 fps=10 max s=1920x1080 fps=60.0002
 vcodec=mjpeg min s=1600x1200 fps=10 max s=1600x1200 fps=60.0002
 vcodec=mjpeg min s=1600x1200 fps=10 max s=1600x1200 fps=60.0002


It says
min fps=10
max fps=60.0002


Actually it supports below fps :


fps=10.00,
fps=20.00,
fps=25.00,
fps=30.00,
fps=50.00,
fps=60.00


How to guess and get the hidden list like : 20, 25, 30 and 50 ?
If I blindly make a list from guessed values,
Some format doesn't have fps=25 on the list and ffmpeg throw error !


Note :
I can not use C++ or .NET to dig further.
Please suggest me some trick to get the proper list from ffmpeg commands only.
Or any universal guess !
