| Summary | 0000313: MVC Interlace decoding is broken when a bitstream contains multiple IDR | ||||
| Description | for interlace encoded bitstreams with multiple IDR, the decoder sometimes exit unexpectedly. An error message is shown "An unintentional loss of pictures occurs! Exit" when it tries to decode the 2nd IDR picture. See attached configuration files, encoding logs and decoding logs. The bitstream is also attached. | ||||
| Steps To Reproduce | 1) encode content with attached configuration file 2) encoding will finish successfully. after that, decode the bitstream with -mpr 1 3) decoding will show the error message at the 2nd IDR and will stop decoding. Only frames before the 2nd IDR will be decoded. | ||||
| Additional Information | 1) Only interlace content has this issue. 2) With all other parameters unchanged, change framerate to 15, set IDRperiod=60, encode 150 frames and it decodes successfully. (when framerate = 25, IDRperiod = 100, encode 150 frames it can not decode the 2nd IDR, IDRperiod is always 4 seconds long) | ||||
