MP4: The first sample count has a problem in SrsMp4SampleManager::write_track

            uint32_t delta = (uint32_t)(sample->dts - previous->dts);

            }
        } else {
            // The first sample always in the STTS table.

stts_entry.sample_count++; // Does this line still need to be incremented here if it has already been done in the subsequent if (previous) statement? } }

What problems will it cause? I can't remember specifically if it's necessary or not.

Need more analysis. So much time has passed that it's as hard as possible for me to reminder.
