Hi Francois, I'm using a third party compiled API, to talk to FFmpeg. I can't change the command line structure. I would have to purchase the API source to do it.
If that is true. They should remove the pages from the website, talking about the feature. But I can see using these files for several of my projects. It's too bad they removed this feature. Thanks, Scott. -----Original Message----- From: ffmpeg-user <[email protected]> On Behalf Of Francois Visagie Sent: September 4, 2018 4:00 PM To: 'FFmpeg user questions' <[email protected]> Subject: Re: [FFmpeg-user] preset files > -----Original Message----- > From: ffmpeg-user [mailto:[email protected]] On Behalf Of > Scott Johnson > Sent: 31 August 2018 15:07 > To: [email protected] > Subject: [FFmpeg-user] preset files > > Hi Everyone, > > > > Here is a newbie question. > > > > I have a C++ API that uses FFmpeg to stream an IP camera to my application. > I can not pass any variables to the background call to FFmpeg, other > than the source rtsp and transport type call. > > > > Here is the command I used to test the FFmpeg settings to make it work > with my camera.

I'd use a wrapper that takes the source and transport type arguments from your API and then specifies the additional settings on the actual ffmpeg command line. > > > > Thanks, > > > > Scotty. > > > > > > > > > > ffmpeg version N-91715-gd71dfc087b Copyright (c) 2000-2018 the FFmpeg > developers > > built with gcc 8.2.1 (GCC) 20180813 > > configuration: --enable-gpl --enable-version3 --enable-sdl2 > --enable-fontconfig --enable-gnutls --enable-iconv --enable-libass > --enable-libbluray --enable-libfreetype --enable-libmp3lame > --enable-libopencore-amrnb --enable-libopencore-amrwb --enable- > libopenjpeg --enable-libopus --enable-libshine --enable-libsnappy > --enable-libsoxr --enable-libtheora --enable-libtwolame > --enable-libvpx --enable-libwavpack --enable-libwebp --enable-libx264 > --enable-libx265 --enable-libxml2 --enable-libzimg --enable-lzma > --enable-zlib --enable-gmp --enable-libvidstab --enable-libvorbis > --enable-libvo-amrwbenc --enable-libmysofa --enable-libspeex > --enable-libxvid --enable-libaom --enable-libmfx --enable-amf > --enable-ffnvcodec --enable-cuvid --enable-d3d11va --enable-nvenc > --enable-nvdec --enable-dxva2 --enable-avisynth > > libavutil 56. 19.100 / 56. 19.100 > > libavcodec 58. 27.100 / 58. 27.100 > > libavformat 58. 17.103 / 58. 17.103 > > libavdevice 58. 4.101 / 58. 4.101 > > libavfilter 7. 26.100 / 7. 26.100 > > libswscale 5. 2.100 / 5. 2.100 > > libswresample 3. 2.100 / 3. 2.100 > > libpostproc 55. 2.100 / 55. 2.100 > > _______________________________________________ > ffmpeg-user mailing list > [email protected] > http://ffmpeg.org/mailman/listinfo/ffmpeg-user > > To unsubscribe, visit link above, or email > [email protected] with subject "unsubscribe". _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe". _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
