Re: [FFmpeg-devel] h264_nvenc encoding issue
>> I already post my mail to ffmpeg-users group regarding this issue but no one could help me out and advised to ask more experienced users. So i hope you can tell me something and sorry posting here. Here is my re-encoding command's output (Windows 8.1 with Bash): *$ ffmpeg -i perspective.mp4 -c:v h264_nvenc -profile:v high -preset:v fast perspective_out.mp4* Please share the i/p file.

Re: [FFmpeg-devel] [PATCH]nvenc: Add capability check for Temporal AQ
>> Temporal AQ is implemented in CUDA, not in silicon. So far does the API (Video SDK 7.0.1) accept the flag without giving any errors. The output however remains identical currently (tested on a GTX 960). You'll have to ask Nvidia why they haven't implemented it yet (i'ts probably too soon). I am expecting it to become available with a future driver (or SDK or CUDA). It's already available for NVENC when encoding H.264/AVC and it's not only a method used in H.264 encoding, but one which is used in H.265 encoding, too (for example does x265 call auto variance '--aq-mode 2'). I am from Nvidia Video Team, so can give a good answer. Currently it has been implemented for H264 only. HEVC TAQ may be released in a future SDK release. All queries for NVENC/CUVID can also be directed to me. Thanks, Yogender ___ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel

Re: [FFmpeg-devel] Patch for fixing of nvenc.c compilation using msvc tools
I agree the change was not good, but since it was not compiling on my system using VS2013 I submitted this, but I hear that rather it may be an issue with my system as the code compiles well using VS2013 tools. I will retry at my end. On Wed, Sep 14, 2016 at 10:08 PM, Timo Rothenpieler wrote: > On 9/14/2016 3:43 PM, Yogender Kumar Gupta wrote: > > Attached is a patch for SDK 7_0 for NVENC.
