This is correct, you cannot use these functions in a portable way. > I also found this function ( > https://www.ffmpeg.org/doxygen/3.0/rtpdec_8c.html#a7775bfcc7505137bfa63f5610908a659) > in the rtpdec.h that calculates the packet loss using the RTPStatisticsread > from RTPDemuxContext. But I don't understand how I would access this > RTPDemuxContext (the function I found that returns this structure is in > rtsp.h, so I'd be back to the previously mentioned problem). You cannot access them but I believe an error is printed on the console every time a sequence error occurs, no? > So, any help regarding these doubts that I have or another different way to > extract the packet loss information would be appreciated! This appears only to be implemented for internal use.
