| Summary | 0000159: JM decoder crashes with a lost NAL unit... (erc_do_p.c)? | ||||
| Description | Hi, I have encoded a YUV file with an H.264 encoder (x264). Then to simulate the channel error, I drop one of the NAL units of this encoded file (in the middle of the video, frame 150). But unfortunately, when I try to decode it with JM decoder I got the following errors: > ldecod.exe decoder.cfg case 1: in decoder.cfg we set Err Concealment mode = 0 in this case I got this error on frame 150 : An unintentional loss of pictures occures! Exit case 2: in decoder.cfg we set Err Concealment mode = 1 or 2 in this case at the begining of the decoding process (at frame 1) I got the following error: 0000(I) 0 0 10 4:2:0 140 Assertion failed: conceal_from_picture != NULL, file c:\jm\lencode\src\erc_do_p.c, line 1725 Actually, in the second case JM crashes. Please note that I can play this encoded file (even in the case that some of its NAL units have been dropped) with VLC player with no error. But what is the problem? Could you please help me? Thank you in advance! [Edited to avoid linking to unrelated bugs, KS] | ||||

Error stability is not of high priority for the JM software. |
|
|
But what is the wrong and how can we solve this error? Thanks |

If I knew a solution, I would have fixed the issue long time ago. The original contributors of the frame error concealment do no longer support it. So somebody will have to read the code, understand how it is supposed to work (see PDF document in bug 0000004) and finally fix it. Volunteer work is encouraged, because the coordinators have limited resources and low priority on error handling. |

how I can to fix Assertion failed: conceal_from_picture != NULL, file ldecod\src\erc_do_p.c, line 1756 for decode a video? |
