The whole patchset looks good.

In "rtprtxsend: fix data locking when creating rtx packets", did you just move the gst_rtx_rtp_buffer_new() function or did you also modify it ?

Just moved. Only removed the starting underscore from the name of the function.

Commited in master.

    examples/*-rtpaux: specify payload type association for the audio stream, so that rtx works also for audio

    rtprtxsend: remove wrong check for payload type not having been set
    
    1) pt can be lower than 96
    2) there is no point in checking that because rtprtxsend will not
       even store buffers for payload types that it doesn't know about,
       so this case will never be reached

    rtprtxsend: fix data locking when creating rtx packets
    
    This patch moves the creation of rtx packets to be done early,
    in the src_event() function, when they are requested. The purpose
    is to run gst_rtp_rtx_buffer_new() with the object locked to
    protect internal data, because if it is done at the pushing stage,
    we would have to lock and unlock multiple times in a row while we
    are pushing the rtx buffers.
    
    Previously there was no locking at all, which was terribly wrong.
