#4234(avdevice:new): Direct3D desktop capture on Windows

#4234: Direct3D desktop capture on Windows ----------------------------------+--------------------------------------- Reporter: cracki | Type: enhancement Status: new | Priority: normal Component: avdevice | Version: unspecified Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | ----------------------------------+--------------------------------------- ffmpeg can use 'dshow' filters or 'gdigrab' to capture the desktop on Windows. However, gdigrab is slow (on Aero-enabled desktops) and dshow desktop capture filters aren't shipped with Windows (3rd party filters require installation with admin rights). in GStreamer, there's a 'dx9screencapsrc' that uses Direct3D 9 and performs reasonably well (~18 fps on my computer). The source of that module can be found at http://cgit.freedesktop.org/gstreamer/gst-plugins- bad/tree/sys/winscreencap/gstdx9screencapsrc.c -- Ticket URL: <https://trac.ffmpeg.org/ticket/4234> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

Re: [FFmpeg-trac] #2686(avcodec:open): Native AAC encoder collapses at high bitrates on some samples

#2686: Native AAC encoder collapses at high bitrates on some samples -------------------------------------+------------------------------------- Reporter: Kamedo2 | Owner: Type: defect | klaussfreire Priority: normal | Status: open Version: git-master | Component: avcodec Keywords: aac | Resolution: regression | Blocked By: Blocking: | Reproduced by developer: 1 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Comment (by klaussfreire): I tracked it all the way to codebook_trellis_rate and encode_window_bands_info with short windows. When the optimum allocation spans more than SCALE_MAX_DIFF sf, anmr is carefull not to create allocations that result in deltas to be encoded greater than SCALE_MAX_DIFF, but codebook_trellis_rate and the other both undo this. I tried many ways to patch that with no avail as of yet. The issue almost always happens near zero bands and the switch from one window group to the next (which is usually where the greatest deltas happen and where it is hardest to enforce). But I did just notice the assertion error happens on git head as well. It seems like a pre-existing bug. Feel free to check exactly under which conditions, I just saw the error logs on a run of tests and didn't get to comparing when it happens vs v9b just yet. -- Ticket URL: <https://trac.ffmpeg.org/ticket/2686#comment:364> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
