I am trying to decode and then re-encode an RTP video-stream. I need to use OpenH264 codec by Cisco. I used this codec with the FFmpeg tool:

ffmpeg -hide_banner \
   -protocol_whitelist file,rtp,udp \
   -err_detect ignore_err \
   -c:v libopenh264 \
   -i /src/stream.sdp \
   -c:v libopenh264 \
   -profile:v high \
   $OUTPUT_FILE &

The stream has a little packet-loss (around 2-3 % in the middle of the stream), and when packet loss occur, the codec print a lot of errors in the logs:

[sdp @ 0x5bfcad506740] max delay reached. need to consume packet 
[sdp @ 0x5bfcad506740] RTP: missed 1 packets
[libopenh264 @ 0x5bfcad560cc0] [OpenH264] this = 0x0x5bfcad6905e0, Warning:DecodeCurrentAccessUnit() failed (468766) in frame: 20 uiDId: 0 uiQId: 0

Because of this, I get an output with a lot of frame freezes. Is it possible to make OpenH264 to decode as many frames as possible, even if artifacts occur?

P.S. I have already tried to use FFmpeg build-in H.264 decoder and it works well. It decodes as many frames as possible and output a video with some artifacts. But I need the same result with OpenH264.
