rtmppkt: Repeat the full 32 bit timestamp for chunking continuation packets
This fixes sending chunked packets (packets larger than the output chunk size, which often can be e.g. 4096 bytes) with a timestamp delta (or absolute timstamp, if it's a timestamp step backwards, or the first packet of the stream) larger than 0xffffffff. The RTMP spec explicitly says (in section 5.3.1.3.) that packets of type 3 (continuation packets) should include this field, if the previous non-continuation packet had it included. The receiving code handles these packets correctly. Pointed out by Cheolho Park. CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>
