| * mpeg12dec: move setting first_field to mpeg_field_start()Anton Khirnov2016-12-191-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For field picture, the first_field is set based on its previous value. Before this commit, first_field is set when reading the picture coding extension. However, in corrupted files there may be multiple picture coding extension headers, so the final value of first_field that is actually used during decoding can be wrong. That can lead to various undefined behaviour, like predicting from a non-existing field. Fix this problem, by setting first_field in mpeg_field_start(), which should be called exactly once per field.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | find_fps attempts to infer framerate from AVCodec's timebase. When this results in a frame rate that isn't explicitly marked as supported in av_timecode_check_frame_rate, find_fps returns the AVStream's avg_frame_rate, which, per avformat.h, _may_ be set (or not). mov_get_mpeg2_xdcam_codec_tag, mov_get_h264_codec_tag and find_compressor attempt to call av_q2d on the return value of find_fps, which in the above case, may result in division by zero and therefore, an undefined frame rate when NaN is converted to int.
