Someone opened an issue https://github.com/intel/libxcam/issues/729 they want to use a FFmpeg video filter pipeline to do multiple decoder, stitching and encoder.
Those 3rd party libs are not necessary for stitching and most image processing functions. By default these 3rd libs are disabled. -----Original Message----- From: ffmpeg-devel <[email protected]> On Behalf Of [email protected] Sent: Thursday, July 30, 2020 5:34 PM To: FFmpeg development discussions and patches <[email protected]> Subject: Re: [FFmpeg-devel] [PATCH] avfilter/vf_xcam: add xcam video filter On Thu, Jul 30, 2020 at 5:15 PM [email protected] <[email protected]> wrote: > > On Thu, Jul 30, 2020 at 5:12 PM Nicolas George <[email protected]> wrote: > > > > zongwave (12020-07-31): > > > From: Yinhang Liu <[email protected]> > > > > > > xcam filter is a wrapper of libxcam project which supports 360 > > > video stitching, automotive surround view stitching, digital video > > > stabilization (DVS), Wide dynamic range (WDR), wavelet noise reduction, > > > 3D noise reduction, etc. > > > > Hi.

My confusion is, where is the boundary of FFmpeg？ in my personal opinion, libxcam is not a self-contained library. _______________________________________________ ffmpeg-devel mailing list [email protected] https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe". _______________________________________________ ffmpeg-devel mailing list [email protected] https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
