Issue with h264depay and avdec_h264 when using rtpulpfecenc/dec !
Hello Sir,
I am currently working on adding elements rtpulpfecenc and rtpulpfecdec to my sender and receiver pipelines respectively. The example program for these were written in rust and uses rtpvp8pay /depay along with vp8enc and vp8dec . Since my application is only compatible with rtph264pay/depay ,I have used , Sender: filesrc >> decodebin >> videoconvert >> queue >> rtph264pay >> Queue >> rtpbin ( rtpulpfecenc > rtpsession ) >> udpsink Receiver : udpsrc>> netsim >>rtpbin ( funnel > rtpsession > rtpstorage > rtpssrcdemux > rtpjitterbuffer > rtpptdemux > rtpulpfecdec ) >> rtph264depay >> h264parse
capsfilter >> *decodebin *>>videoconvert >> videoscale >> capsfilter >> x264enc >> matroskamux >> filesink
I am setting the fec percentage as 10 on sender and drop as 1 % on receiver side , I am getting the ratio of packets unrecovered : recovered , But Issue is that decode bin at the receiver side uses *avdec_h264 *internally as decoder , it is producing the following errors,

/ Is there any elements that I need to add when i use other pay/depay instead of VP8 ,or is this because of any wrong configuration? / Please Help me with this situation, Eagerly Waiting for a response.
