There is a commented code that if, activated, shows whether there are broken_link_flag in a h.264 stream.
Want to use it? Find 'broken_link_flag is 1' and uncomment that part of code. Than compile and use esdots. --HG-- extra : convert_revision : svn%3Aeff31bef-be4a-0410-a8fe-e47997df2690/trunk%4073issue20
