Ok, so looking at older flags, I need to add a define to version.h, something like #ifndef FF_API_LAVF_MP4A_LATM #define FF_API_LAVF_MP4A_LATM (LIBAVFORMAT_VERSION_MAJOR < 59) #endif and place the flag under guard in avformat.h And place same guard in the options table. Is that correct? I assume the other changes can be committed as-is. Thanks, Gyan

Change the description of the option in this table into something like "Deprecated, does nothing" while at it as well. > > Is that correct? > > I assume the other changes can be committed as-is.
