  • ffmpeg : cut from left (with -ss) - incorrect result

    20 novembre 2018, par Kirill Zhirnov

    I have an auto generated video from image (30 secons) :

    ffmpeg -loop 1 -i img1.png -f lavfi -i anullsrc -pix_fmt yuv420p -c:v libx264 -c:a aac -ar 44100 -ac 2 -t 30 img.ts

    I need to cut it. If I cut it from right (e.g from 0 seconds to 5) - it works fine :

    ffmpeg -ss 0 -i img.ts -to 5 -c copy cropped.ts

    But if I want to cut it from left (e.g from 5 second to 8) - the result is damaged video :

    ffmpeg -ss 5 -i img.ts -to 8 -c copy cropped.ts

    What should I do to fix it ?

    Thanks in advance !

  • Embedding Metadata to H.264 encoded file

    7 septembre 2012, par kerim yucel

    I am currently developing an application which produces certain metadata with respect to preview frames coming from the camera. I can see this metadata being produced properly and I have no problems here.

    However, I have to embed this metadata to these frames of interest (frames are processed by a native algorithm to produce this metadata). I am using ffmpeg with x264 to encode the frames into H.264. I have checked x264.h and some documentations but failed to find what I seek.

    My question is ; is there any unused portion of H.264 syntax that I can embed my metadata to encoded frames ?

    I hope I was clear enough. Thanks in advance.

  • Is there a need to apply Deblocking filter, when I have all Intra frames Encoding

    31 août 2015, par Codec Guy

    I am working on H.264 Deblocking Filter and need some clarity.

    • While designing an all Intra Encoder and Decoder, is it mandatory to
      add Deblocking Filter block in the Codec.
    • If deblocking filter is not enabled for all Intra Encoding does that
      cause any PSNR degradation(I checked few streams the PSNR almost
      remained the same).
    • If I am encoding all my frames using Intra prediction, does that also
      have any blocking artifacts.

    Thanks in advance
