#3399: Scaling MP4 Video results in bad output MP4 --------------------------------------+---------------------------------- Reporter: mressler | Type: defect Status: new | Priority: normal Component: undetermined | Version: 2.1.3 Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | --------------------------------------+---------------------------------- Summary of the bug: Attempting to scale an MP4/H264 1920x1080 source video to 1024:-1 (also Mp4/H264) results in odd playback in different players. VLC shows green box artifacts, QuickTime and MPlayer both show jerky/slow playback. How to reproduce: (Grab source from: https://www.dropbox.com/s/thy8zxbvx1ygqru/VID_20130619_161750_449.mp4) {{{ % ffmpeg -i VID_20130619_161750_449.mp4 -vf "scale=1024:-1" VID_scaled.mp4 }}} VID_scaled.mp4 ends up with green artifacts in VLC and doesn't play appropriately in QuickTime or MPlayer. Interestingly, if I clip the video first via: {{{ % ffmpeg -i VID_20130619_161750_449.mp4 -ss 18 -t 15 -c:v copy -c:a copy clip2.mp4 }}} And then run the scale command: {{{ % ffmpeg -i clip2.mp4 -vf "scale=1024:-1" VID_clip_scaled.mp4 }}} The resulting video plays fine in VLC, QuickTime, and MPlayer. -- Ticket URL: <https://trac.ffmpeg.org/ticket/3399> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#3409(undetermined:new): Impossible to transcode full range RGB videos with libx264, and keep full range + proper colors

#3409: Impossible to transcode full range RGB videos with libx264, and keep full range + proper colors -------------------------------------+------------------------------------- Reporter: mzso | Type: defect Status: new | Priority: normal Component: | Version: undetermined | unspecified Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- I encountered this while trying to transcode screencasted videos with fraps or ut-video streams. When using yuv444p pixel format I get washed out, too light videos. "-color_range" has no affect. People suggested: "-vf colormatrix=bt601:bt709" But it also doesn't have an affect. x264 itself has issues with RGB full range videos, if I use i444 with it I also get improper output. But if I use "--output-csp rgb" it succeds in encoding a proper output file, though with a large file size. I can't even achieve this with ffmpeg because it doesn't let me use RGB with libx264: "Incompatible pixel format 'rgb24' for codec 'libx264', auto-selecting format 'yuv444p'" -- Ticket URL: <https://trac.ffmpeg.org/ticket/3409> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#3389: Feature Request - Isolate and normalize video content -------------------------------------+------------------------------------- Reporter: Rafajafar | Type: Status: new | enhancement Component: ffmpeg | Priority: wish Keywords: feature | Version: request normalize video | unspecified Blocking: | Blocked By: Analyzed by developer: 0 | Reproduced by developer: 0 -------------------------------------+------------------------------------- Hey, I have an interesting problem and I'm solving it with OpenCV. It's be great if the solution could come straight from ffmpeg, though! I need to: 1) cropdetect 2) crop surrounding borders from a video 3) resize video to normalize its dimensions In other words, all I want is one command that will detect the frame-by- frame borders and in the same step, crop it, and also resize it. And I want this done for the entire video, not a single frame. It's gotta be possible, right? The applications are very useful in video analysis. I've spoken to colleagues of mine and they are doing this manually themselves. It would be great to be able to work this feature into the automation surrounding ffmpeg in our tools. My personal application, for instance, is in detecting videos that are similar using content perceptual hashing. Another colleague of mine works for the Center for Missing and Exploited Children. He does similar work, but with pHashing. I can see applications for ContentID type systems across the board. I'm sure this is a low on the totem pole request, but if you have any spare cycles, this would really rock in the world of computer vision and video analysis! Thanks for your consideration, --Collin -- Ticket URL: <https://trac.ffmpeg.org/ticket/3389> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

Works under Linux with the same version. Is this a bug or is there anything i'm missing? Same commandline works just fine under linux with the same git-version. There are no space issues. Both ffserver and machine running windows has plenty of space available. {{{ ffmpeg -i http://10.10.0.108:7522/upnp/channelstream/18.ts http://10.0.1.100:8090/feed1.ffm ffmpeg version N-60859-g313a6c6 Copyright (c) 2000-2014 the FFmpeg developers built on Feb 23 2014 22:01:50 with gcc 4.8.2 (GCC) configuration: --enable-gpl --enable-version3 --disable-w32threads --enable-av isynth --enable-bzlib --enable-fontconfig --enable-frei0r --enable-gnutls --enable-iconv --enable-libass --enable-libbluray --enable-libcaca --enable-libfreetype --enable-libgsm --enable-libilbc --enable-libmodplug --enable-libmp3lame --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libopenjpeg --enable-libopus --enable- librtmp --enable-libschroedinger --enable-libsoxr --enable-libspeex --enable-libtheora --enable-libtwolame --enable-libvidstab --enable-libvo- aacenc --enable-libvo-amrwbenc --enable-libvorbis --enable-libvpx --enable-libwavpack --enable-libx264 --enable-libx265 --enable-libxavs --enable-libxvid --enable -zlib libavutil 52. 65.100 / 52. 65.100 libavcodec 55. 52.102 / 55. 52.102 libavformat 55. 33.100 / 55. 33.100 libavdevice 55. 10.100 / 55. 10.100 libavfilter 4. 1.103 / 4. 1.103 libswscale 2. 5.101 / 2. 5.101 libswresample 0. 17.104 / 0. 17.104 libpostproc 52. 3.100 / 52. 3.100 [mpeg2video @ 0441f640] Invalid frame dimensions 0x0.

#3396: Intel DXVA2 H.264 Improvements for SNB GPUs -------------------------------------+------------------------------------- Reporter: afedchin | Type: Status: new | enhancement Component: avcodec | Priority: normal Keywords: dxva h264 | Version: git- Intel | master Blocking: | Blocked By: Analyzed by developer: 0 | Reproduced by developer: 0 -------------------------------------+------------------------------------- There are a set of patches for add some improvements for SandyBridge/IvyBridge Intel GPUs. This still actual for SNB GPU. The latest drivers for IVB/Haswell doesn't include the old DXVADDI_Intel_ModeH264_E device and doesn't experience the issue but SNB still. http://patches.libav.org/patch/35320/ http://patches.libav.org/patch/35321/ See discussion https://lists.libav.org/pipermail/libav- devel/2013-March/043945.html for more info. The main issue is h264 with refs > 11 decoded on DXVADDI_Intel_ModeH264_E device with artifacts. And solution is use standard Microsoft H264 device DXVA2_ModeH264_E but decoding with Microsoft H264 on SNB will no work without this improvements. This still actual for lastest git-master. -- Ticket URL: <https://trac.ffmpeg.org/ticket/3396> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
