I can use GPU acceleration. My mind is blown! Such smooth playback, such smooth blurs... beautiful... Works: 1. Adding video to project bin 2. Dragging video from bin to timeline 3. Playing back clip in timeline 4. Clicking around the timeline quickly 5. Adding any of the GPU effects Doesn't work (after starting fresh Kdenlive project): 1. click on clip monitor, then click project monitor: http://codepad.org/Iz5gnc4U 2. import video, drag to timeline, play it back, click on project bin white space http://codepad.org/UATIGKel Video of the two crashes above: https://youtu.be/wvJ2gfr9m_c Can't reproduce, I probably didn't document small steps that contributed to the crash. I'm including this in case the gdb/bt output is useable nonetheless: 1. clicking on the clip monitor (while one clip is in the bin and being used in timeline): http://codepad.org/snQkdVq7 2. clicking on the project monitor in an empty project: http://codepad.org/qAWxCLli 3. clicking the timeline in an empty project: http://codepad.org/W0Y9Nes0 4. clicking empty space in the project bin while one clip is loaded: http://codepad.org/kSyzp1Dl Not tested: 1. Rendering 2. Loading projects 3. Many more things -- You are receiving this mail because: You are watching all bug changes.
