Hey guys, Here are my results. One note: I encountered the 1080i playback bug that Marcin Kostur reported a few weeks back, wherein 1080i output plays back normally (~30fps) from the start of the video, but slows down considerably to 2fps if you choose a random point within the video.
This bug documented here: http://bugs.cinelerra.org/show_bug.cgi?id=348 However, this bug has not been resolved, other than in the fix that Marcin found: https://init.linpro.no/pipermail/skolelinux.no/cinelerra/2006-November/008696.html Could any of the programmers update Bug 348 to let us know if this fix is sufficient? thanks, scott PS - here are my results of the playback: System: Cinelerra CVS, SVN r947 Dell 400SC, 3.2Ghz, 800FSB, 2GB 400Mhz, Dual DDR, ECC 250GB SATA system drive Nvidia GEForce 7600GS 8xAGP video card, 512MB memory Project Format: 1080i preset Driver: X11-OpenGL or X11-XV Playback every frame/Decode frames async: unselected Compositor: 75% spanned across two monitors Playback FPS (from beginning of video): OpenGL: 30.15, XV: 29.4 Playback FPS (from 3 seconds into the video): OpenGL 2.21, XV: says 29.94, but that is not correct, as playback is slowed considerably When I playback the video, I get a bunch of these messages in the terminal window in which I started cinelerra: mpeg3_read_prev_packet 100 result=0 title=0 tell=5866ff8 program_byte=5866ff8 mpeg3_read_prev_packet 1 result=0 title=0 tell=5866ff8 program_byte=5866ff8 /sbin/hdparm -t -T /dev/sda /dev/sda: Timing cached reads: 2528 MB in 2.00 seconds = 1263.76 MB/sec Timing buffered disk reads: 116 MB in 3.01 seconds = 38.58 MB/sec iostat output (average): avg-cpu: %user %nice %sys %iowait %idle 73.83 0.00 3.10 0.00 23.08 cat /proc/meminfo: MemTotal: 2070884 kB MemFree: 812096 kB Buffers: 62404 kB Cached: 407492 kB SwapCached: 0 kB Active: 973628 kB Inactive: 199840 kB HighTotal: 1179088 kB HighFree: 66404 kB LowTotal: 891796 kB LowFree: 745692 kB SwapTotal: 0 kB SwapFree: 0 kB Dirty: 8 kB Writeback: 0 kB AnonPages: 703688 kB Mapped: 79100 kB Slab: 58140 kB PageTables: 7232 kB NFS_Unstable: 0 kB Bounce: 0 kB CommitLimit: 1035440 kB Committed_AS: 2329572 kB VmallocTotal: 116728 kB VmallocUsed: 43068 kB VmallocChunk: 67060 kB HugePages_Total: 0 HugePages_Free: 0 HugePages_Rsvd: 0 Hugepagesize: 2048 kB I got 29.94 fps.
