Hello,
I've been tasked with building FFMPEG with Cisco's OpenH264. I'm doing this on
Ubuntu Linux 64.
My understanding is that all I need is
> configure --enable-libopenh264> make
I have 2 questions:
1) The building process proceeded almost flawlessly, until I hit the errors
below. Can anybody suggest a workaround?
2) I did NOT use either --enable-gpl or --enable-nonfree. I had been using
libx264 up to now but want to make sure I will be using Cisco's OpenH264. The
way I select H264 is with the code
avformat_alloc_output_context2 (&oc,NULL,"mp4",NULL);
oc->oformat->video_codec = AV_CODEC_ID_H264;
This has been working just fine. Once I enable openh264 can I still use the
line above to select H264, or is the enumerated type above strictly for
libx264? If so, what change should I make to use openh264?
Thanks.
Here are the errors:
