You can pull from my github, the patches are in the chromakey branch: https://github.com/BtbN/FFmpeg/tree/chromakey If you want just the chromakey patch itself: https://github.com/BtbN/FFmpeg/commit/29294c283a656cf809461cbae21d612b5a0f2159.patch Hi I downloaded and merged the patch again, but the error still exists as follow: $ git am opencl_chromakey.patch Applying: avfilter/vf_chromakey: Add OpenCL acceleration fatal: corrupt patch at line 380 Patch failed at 0001 avfilter/vf_chromakey: Add OpenCL acceleration When you have resolved this problem run "git am --resolved". If you would prefer to skip this patch, instead run "git am --skip". To restore the original branch and stop patching run "git am --abort". I check the code, These codes are in the patch of corrupt patch at line 380. @@ -192,6 +368,7 @@ AVFilter ff_vf_chromakey = { .priv_size = sizeof(ChromakeyContext), .priv_class = &chromakey_class, .init = initialize_chromakey, + .uninit = uninitialize_chromakey, .query_formats = query_formats, .inputs = chromakey_inputs, .outputs = chromakey_outputs, the following codes are the latest ffmpeg master branch codes.

Could you please fix it? Thanks Best regards _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
