Andreas Rheinhardt 43991dbd05 avformat/assenc: Fix potential NULL + 1 
Incrementing a NULL pointer is undefined behaviour,
yet this is what would happen in case trailer were NULL
before the check.

session, use the corrected values to initialize the session.

Yeoh, Hoong Tee da4b2549c6 lavf/rtpenc_jpeg: Retrieve sampling factor from SOF0 
In ff_rtp_send_jpeg, the type is defined based on PIX_FMT and
color-range parsed in. There is limitation on current design
where need to include support newly introduced PIX_FMT such as
AV_PIX_FMT_QSV and there might be more and more in future. Hence,
retrive the sampling factor from SOF0 in JPEG compressed header
directly. This introduces flexibility to handle different type of
new codec introduced in future.
