File libdv-filesizecheck.patch of Package libdv
The patch checks if the file is smaller than the smallest video frame size, and if it's smaller, there can't be a valid video file in it, hence, the file is truncated and there is nothing to play in it. See https://bugzilla.novell.com/show_bug.cgi?id=157631 for further information. --- libdv/playdv/playdv.c 2006/03/21 11:12:19 1.1 +++ libdv/playdv/playdv.c 2006/03/21 11:33:05 @@ -344,6 +344,11 @@ if (!dv_player->no_mmap) { if(fstat(fd, &dv_player->statbuf)) goto fstatfail; eof = dv_player->statbuf.st_size; + if (eof < sizeof(dv_header_t) + 120000) { /* 1st frame incomplete */ + fprintf(stderr, "playdv: File size of %d bytes " + "smaller than frame size, nothing to play!\n", eof); + exit(-1); + } } dv_player->decoder->quality = dv_player->decoder->video->quality;
