Steven,
Thanks for your response.
You mean when I send a FLV tag ( a frame),and when the sending AMF
header is 12 bytes,I should place the absolute ts in the header and
when the header is 4 or 8 bytes , I should place the relative ts in
the header?
I have tried sending each FLV tag with 12 bytes header in the sending
AMF,it didn't work. Here's what I've sent after receiving the 'play'
call:
1. onStatus, type:call(0x14),code: NetStream.Play.Reset
2. onStatus, type:call(0x14),code: NetStream.Play.Start
3. onStatus, type:notify(0x12),code: NetStream.Data.Start
4. 1st tag in the FLV file, type: metadata(0x12)
5. 1st video tag in the FLV file,type video(0x9), in 12 bytes header (6 chunks):
chunk1 header : 08 00 00 00 00 02 b4 09 01 00 00 00 <data>
chunk2 header: C8 <data>
chunk3 header: C8 <data>
chunk4 header: C8 <data>
chunk5 header: C8 <data>
chunk6 header: C8 <data>
6.2nd video tag in the FLV file,type video(0x9), in 12 bytes header (2 chunks):
chunk1 header: 08 00 00 42 00 00 a1 09 01 00 00 00 <data> (
absolute ts 0x42)
chunk2 header: c8 <data>
7. 3rd video tag in the FLV file,type video(0x9), in 12 bytes header (2 chunks):
chunk1 header: 08 00 01 0a 00 00 98 09 01 00 00 00 <data>
(absolute ts 0x010a)
chunk2 header: c8 <data>
8. 4th video tag in the FLV file,type video(0x9), in 12 bytes header (6 chunks):
chunk1 header: 08 00 01 4d 00 02 b2 09 01 00 00 00 <data>
(absolute ts 0x014d)
chunk2 header: C8 <data>
chunk3 header: C8 <data>
chunk4 header: C8 <data>
chunk5 header: C8 <data>
chunk6 header: C8 <data>
What's the problem? Thanks.
