  • av_read_frame of ffmpeg in windows always returning packet.stream_index as 0

    17 février 2015, par yanqing lu

    I’m using ffmpeg to demuxer, for some video like the windows’s sample Wildlife.wmv, the av_read_frame is always returning packet.stream_index=0. This leads the video queue very big and memory overflow. I get 15 frames of video, but only 1 frame of audio. Is there some options to control the av_read_frame, so I can read frames like : video-audio-video-audio, in this way it’s easy to sync AV and keep queue balance.

    Thanks in advance.

  • Using ffmpeg on Windows, what is the command to capture hardware encoded H264 stream from Logitech c930e

    2 mai 2015, par Jeff

    I am using ffmpeg on Windows 8 and I would like to capture the built-in H264 hardware encoded stream from the Logitech c930e camera. The H264 built-in encoded stream is part of the UVC 1.5 interface.

    Using this command I have noticed that the c930e exposes two video pins through DirectShow : 0 and 1.

    ffmpeg -report -list_options true -f dshow -i video="Logitech Webcam C930e"

    [dshow @ 0000000002d89360]  Pin "Capture" (alternative pin name "0")

    [dshow @ 0000000002d89360]  Pin "Capture" (alternative pin name "1")

    It doesn’t seem to matter if I choose Pin 0 or 1, I still get raw video from the Logitech c930e webcam. On Linux, the supposed command involves v4l2, but this does not appear to exist in the default Windows version of ffmpeg from http://ffmpeg.zeranoe.com/builds/

    Does the default Windows build of ffmpeg support the direct capture of the UVC interface ?

    This is the closest I have gotten on this journey, but still isn’t quite right :

    ffmpeg -report -f dshow -i video="Logitech Webcam C930e" -s 1920x1080 -r 30 -video_pin_name 1 -vcodec H264 -c copy -f mp4 Logitechc930eFeed.mp4

    As of April 17, 2015 I am still trying to figure this out and have two new pieces of info.

    I found this interesting article on Logitech’s website instructing the user to change the default Logitech driver to the generic USB Video Device driver :
    https://support.logitech.com/en_us/article/Install-native-UVC-drivers-for-your-Logitech-webcam?product=a0qi00000069v0MAAQ#

    I also found that my C930e had an older firmware (8.0.866), and Logitech recommends updating the firmware to 8.0.875 to fix an unspecified UVC H.264 issue.

    So now I have the latest firmware, and am using the generic "USB Video Device" on Windows 8.1.

    ffmpeg -list_devices true -f dshow -i

    which gives this output :

    cmdutils : Only do the windows-specific commandline parsing on _WIN32

    Fixes commandline parsing on Cygwin (on 64 bit, and on very recent
    
32 bit), where the configure check does find the CommandLineToArgvW
    
function (since it exists in the link libraries and in the headers),
    
but whose GetCommandLineW() only returns the application’s path.
    
(This is due to a cygwin internal optimization, see
    
http://cygwin.com/ml/cygwin/2013-07/msg00538.html for details.)
    
Arguments are only given through main’s argc/argv, and they’re already
    
UTF-8.
