| Summary | 0000250: "Warning: RTP sequence number discontinuity detected" |
|---|
| Description | I was trying to decode a .264 where the bitstream has some packet lossed (generated using rtp_loss model) but it exit program abnormally and shows msg
"Warning: RTP sequence number discontinuity detected". If i try to decode a bitstream that does not have any packet loss in that case it works fine. I uses RTP in both encoder(OutFileMode = 1) and decoder(FileFormat = 1) config file.
In additional information area i pasted the decoder.cfg file.
Please follow steps to reproduce. |
|---|
| Steps To Reproduce | 1. encode a yuv file
2. do some packet loss using rtp_loss model,
ex: rtp_loss carphone_qcif_15fps.264 carphone_qcif_15fps_loss_50.264 50
3. now use carphone_qcif_15fps_loss_50.264 in decoder.cfg as input file
4. try to decode the bitstream using ldecode and see the output, in my case i got the warning, please see the attached snapshot |

| Additional Information | decoder.cfg
