It looks like the ffmpeg code has a small problem. The source references externals declared in a header that is not normally available. The previous git versions do not require this new interface, and do not exhibit the problem. I added a patch that removes the feature that is added that causes the problem. It is not necessary and will use the fallback resources (just as it was before the new code changes) and should work well. Additionally, I updated the ffmpeg.git.patch* set to the current ffmpeg get repo commit 12bbfc4ccaa150e06895691049fa2ea33385d210 This ports patches we currently use, and adds a few new/fixed patches for problems and features we use in cin5. It is not well tested, but seemed to work for the problems I tried. Most of them are pretty safe. The mpegtsenc.c patch was a major rework, and represents the highest risk. We were able to create blurays and test on players, as well as ffplay and cin5 playback. Let me know if you have any problems. This has only a few hours of testing. BTW. I did try the ffmpeg vanilla mpegtsenc (current version) and it does not work with the samsung and LG bluray players. There are needed changes in the patches. gg
