  • lsws : duplicate ff_log2_tab

    lsws : duplicate ff_log2_tab

    libswscale uses the table but wasn’t duplicating it like the rest of the libs.
    
This should fix compilation failures on msvc/icl after lavu stopped exporting
    
internal functions and tables.

  • Problems using Cuda for video transcoding [closed]

    19 août 2022, par Jay Adlard

    I just bought a new pc as my faithful old windows 7 i7 laptop died. Now the laptop had both intel and nvidea gtx660m chips. When I transcoded video with handbrake the intel graphics managed 8fps when I changed over to the nvidia it managed 80fps and the graphics card got nice and hot so was obviously working.

    &#xA;

    The new machine i bought is a i9 with an nvidea gtx780 running windows 10. When I tried to transcode some video hoping for it to use the cpu and Gpu but no joy,the card stays cool power usage is only a handful of watts higher than it running something simple.I had been using handbrake but I read it doesn’t support Cuda so why the laptop speeded up I don’t know. A friend of mine that is into ffmpeg came round found that ffmpeg reports no Cuda yet the card works fine in every other respect. Unlike the rest of the machine the graphics card wasn’t new but it looked like new…

    &#xA;

    One thing to note I am not talking about nvenc as the quality is rather poor, no point in capturing uncompressed files cleaning them up and not using an encoder that will do 2 pass and an exhaustive search.&#xA;Can anyone recommend a reasonably priced encoder that will use the Cuda cores ?

    &#xA;

    Has anyone got any idea what the problem is ?

  • Getting motion vector side data from ffmpeg from the compressed domain (without performing full decode)

    4 mai 2019, par John Allard

    The ffmepg source code comes with a file extract_mvs.c which is quite helpful in showing how to extract the motion vectors from an h264-encoded video file. Unfortunately, it performs a full decode before getting the motion vectors from the side data of the stream.

    One should be technically able to (as was confirmed by FFMPEG developer Carl Eugen in this thread https://ffmpeg.org/pipermail/libav-user/2016-December/009913.html) get the motion vectors from the compressed domain before performing a full decode step. This would obviously be less computationally intensive as one wouldn’t have to perform a full decode.

    Is it possible to do this with ffmpeg/libavcodec as is ? I know Carl said that it wasn’t possible but that was 3 years ago. If it is not currently possible, does anyone have any hints on how one would go about modifying the ffmpeg source code to do this ?

    Thanks
