    Le lecteur ne fonctionne pas sur Internet Explorer

  • Encoding 25mp video

    18 août 2016, par Yuval.Sightec

    I have a 25MP uncompressed video file of 100 frames.

    I tried to encode it with ffmpeg and h264 encoder into a .mp4 file, but the encoding got stuck around the 10th frame.
    This is the script :

    avconv -y -i input.avi -c:v libx264 -preset medium -b:v 5000K -pass 1 -c:a libfdk_aac -b:a 5000K -f mp4 /dev/null && \
    
avconv -i input.avi -c:v libx264 -preset medium -b:v 5000K -pass 2 -c:a libfdk_aac -b:a 5000K output.mp4

    I am running it on a jetson TK1 with nvidia gpu, is there any way to use an accelarating encoding in order to make the encoding possible ?

    Please, if you can, give me a sampler script of something that might work.
    Right now, I dont care how much time the encoding take, as long as it will work.

    Thank you in advance ! :)

  • lavfi/delogo : take SAR into account

    lavfi/delogo : take SAR into account

    When interpolating, weights are based on relative distances, which
    
assume square pixels. If a non-1:1 sample aspect ratio is used, it
    
should be taken into account when comparing distances, because the
    
human eye and brain care about the picture as it is displayed, not
    
stored.

    lavc/hevcdec : call ff_thread_finish_setup() even if hwaccel is in use

    Serializing frame threading for non-threadsafe hwaccels is handled at the
    
generic level, the decoder does not need to care about it.
