** Description changed: + SRU Justification + ~~~~~~~~~~~~~~~~~ + + Impact: + + Currently Brasero will fail to write files to a disc in on-the-fly + mode using the libburnia plugin resulting in 'coastered' media. + This is the default mode of operation and unless the user is writing + a pre-built ISO image, this fails 100% of the time and has since Oneiric + -- possibly Natty. + + Fix: + + Revert part of the following commit: + + http://git.gnome.org/browse/brasero/commit/?id=1b8397ee252df2d554682ca2d694d5937fbf6e39 + + Particularly the chage to plugins/libburnia/burn-libisofs.c around line + 200 that adds an additional priv->libburn_src->read_xt() call. + + Patch: + + http://git.gnome.org/browse/brasero/commit/?id=253031b69c5dcbcf079c445ec530afb7ccd9ea82 + + Test Case: + + * Insert blank CD or DVD in drive: + + (1) Attempt to write files to the writable optical disc by dragging + files from Nautilus to a blank disc. + + (2) Click on the 'Write Files to Disc' button in nautilus. + + (3) Make sure 'on the fly' mode is enabled by selecting 'Burn image + directly without saving to disc' (which should be the default). + + (4) Click on the 'burn' button. + + * If the bug is fixed, you should have a properly written and readable + disc. Otherwise, the procedure will fail and the disc will be unusable. + + ---------- + Binary package hint: brasero When I burn a DVD (4,7 and 8,5 GB) Brasero show the progressbar till about 30-40% (exact point is randomly) and than says, that it is finalizing the media. This finalizing messages is showing for the rest of the burning process (~10min @8x 8,5GB). After that, it ejects the media without any error. But when I insert the media again, nothing happens, except, that the DVD-Drive disappears from the "computer:///" location in nautilus. This problem only exists when burning On-The-Fly. Burning ISO Images or automatic creation of ISO Images before burning works without problems. The burning speed doesn't matter to this problem. I test 8x, 4x and 2x. All the same problem. On-The-Fly burning using K3B works quite well @8x speed. One thing I also notice is, that Brasero uses 100% CPU on one core, while K3B uses just about 5-15%. I attached the last Brasero log. I don't know, why it just says, that it was only at 49% and then says it's finished. The burning took about 28 minutes. The media was unusable on all my three devices (Linux/Windows).
