and i give you 2 blocks from cam.
Steps to get sigsegv:
1.put "frames_63.frm.3" in frame(QByteArray)
AVPacket *avpkt=new AVPacket;
avpkt->size=frame.count();
avpkt->data=(uint8_t*)frame.data();
int len =avcodec_decode_video2(codecContext,picture,&got_picture,avpkt);
here i get len<0 (Error while decoding frame) and i decide drop frame.So
frames_63.frm.3 lost.
2.put "frames_63.frm" in frame(QByteArray)
AVPacket *avpkt=new AVPacket;
avpkt->size=frame.count();
avpkt->data=(uint8_t*)frame.data();
int len =avcodec_decode_video2(codecContext,picture,&got_picture,avpkt);
and i crash on avcodec_decode_video2.
3.If you try to decode only frames_63.frm whithout frames_63.frm.3 than you have
no crash
now core was little different
