Sorry for the confusion. Yes, "old code” relates to my app and ndn-cpp library that I used.
<div class="">I just want to understand more why packet is being dropped. Based on your reply, it seems that interests use selectors. I’ll check that first...</div>

<div class="">I don't understand what you mean by "old code", what is old? Your app? The library? NFD? All of them? What library is your app using?</div>

<div class="">Are you using any v0.3 packet format features in your app, such as Interest Parameters? If so, or if for some other reason your library is encoding the Interest in v0.3 format, then the decoder in NFD will not accept any TLV elements that were

Hi devs,<br class="">
<br class="">
<br class="">
I recently noticed that I can’t fetch ndnrtc video stream with somewhat old (~2months) code. In the app I’m getting timeouts:<br class="">
<br class="">
1543953646377 [WARN ][ remote-stream]- operator(): error fetching stream meta: Time out for interest /touchdesigner/ndnrtcOut/ndnrtc/%FD%03/video/s/_meta<br class="">
<br class="">
while in NFD log I observer these messages:<br class="">
<br class="">
1543953961.057775 WARNING: [GenericLinkService] [id=287,local=<a href="unix:///private/var/run/nfd.sock,remote=fd://73" class="">unix:///private/var/run/nfd.sock,remote=fd://73</a>] packet parse error (unrecognized element of critical type 9): DROP<br class="">
<br class="">
Face 287 is an application face:<br class="">
<br class="">
faceid=287 remote=<a href="fd://73" class="">fd://73</a> local=<a href="unix:///private/var/run/nfd.sock" class="">unix:///private/var/run/nfd.sock</a> congestion={base-marking-interval=100ms default-threshold=65536B} counters={in={0i 0d 0n 1120B} out={0i
0d 0n 0B}} flags={local on-demand point-to-point congestion-marking}<br class="">
<br class="">
I was wondering whether these DROP messages relate to my code or not. I still can fetch video with my latest code though.<br class="">
<br class="">
I’m using NFD 0.6.4 (macOS).<br class="">
<br class="">
Thanks, <br class="">
<br class="">
