In this mode, the parsers look for the best sync sample from the first 10 sync samples. "Best" here is defined as the biggest frame in terms of bytes with the rationale that an I-frame with more number of bytes will have more pictorial information compared to the others.
So, first and foremost, you need to check how many I-frames is your encoder producing, if any? If there are I-frames, look at the mp4 parser node to see why you are not seeing any thumbnail. Or, file a bug, along with the clip in question, and we can take a look. -Ravi On Jun 8, 1:41 am, Jia Meng <dspm...@gmail.com> wrote: > I found there is a macro "BEST_THUMBNAIL_MODE" defined in > metadriver.h.
