[FFmpeg-user] Ffmpeg compilation issues

[Ronak]

Hi all,

I'm trying to build the latest HEAD version of Ffmpeg on Linux on the following platform.

Linux 4.9.124-0.1.ac.198.71.329.metal1.x86_64 #1 SMP Thu Aug 30 20:39:05 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

But, I'm getting compilation problems:

libavcodec/v4l2_m2m_enc.c: In function ‘v4l2_set_ext_ctrl’:
libavcodec/v4l2_m2m_enc.c:51: warning: braces around scalar initializer
libavcodec/v4l2_m2m_enc.c:51: warning: (near initialization for ‘ctrls.count’)
libavcodec/v4l2_m2m_enc.c:55: error: ‘struct v4l2_ext_controls’ has no member named ‘ctrl_class’
libavcodec/v4l2_m2m_enc.c:60: error: ‘struct v4l2_ext_control’ has no member named ‘value’
libavcodec/v4l2_m2m_enc.c: In function ‘v4l2_get_ext_ctrl’:
libavcodec/v4l2_m2m_enc.c:71: warning: braces around scalar initializer
libavcodec/v4l2_m2m_enc.c:71: warning: (near initialization for ‘ctrls.count’)
libavcodec/v4l2_m2m_enc.c:76: error: ‘struct v4l2_ext_controls’ has no member named ‘ctrl_class’
libavcodec/v4l2_m2m_enc.c:89: error: ‘struct v4l2_ext_control’ has no member named ‘value’
make: *** [libavcodec/v4l2_m2m_enc.o] Error 1

It looks like Ffmpeg is not finding the correct unions in the file: /usr/include/linux/videodev2.h.

What do I have to set to make compilation succeed?

Thanks,

Ronak
