2 months ago As you say, especially for PPS, it should be accumulated each pic_parameter_set_id separately.
I don't know if there are any practical examples of using multiple VPS/SPS.
The problem is that Fragmented MP4 seems not to support multiple PPS. I have looked into related stackoverflow, and there appears to be multiple (probably unofficial) ways to do it.

iam again
do you think VPS SPS PPS can be only once per PES ? no is can split per PES as example i have AVC PES stream AUD[2],SPS[23],PPS[4],PPS[95],PPS[5],SEI[8],I(1)Slice(7)[40793]
per AVC/HEVC Config Record VPS can be 15 counts SPS can be 31 counts PPS can be 255 counts
so i think place where assign VPS,SPS,PPS should be impove or reimplement
as example, this is wrong it should accumulate ber counts, after counts overflow, should ParseXXX
yes, usefull info which used for produce mp4 can be at first VPS,SPS,PPS counts, but anyway it can make incorrect
