• Revision ba8b5e8d6d : Use separate inter predictors for enc/dec The decoder will construct inter pred

  22 novembre 2013, par Jingning Han

  Use separate inter predictors for enc/dec

  The decoder will construct inter predictor using lazy border extension,
  while the encoder, going with multiple runs of motion search in the rate-
  distortion optimization loop for each block, does border extension at
  frame level. This commit makes separate the inter predictors for encoder
  and decoder, respectively.

• How multiple DirectShow buffers work ?

  3 février 2014, par dtumaykin

  DirectShow filters allow to allocate multiple buffers in DecideBufferSize.

  I have a transform filter that encodes raw frames with x264, generating 1+ NALs to pass upstream to next filter. I thought that allocating a pool of buffers for NALs can be a solution, but I can’t figure out how to access all the buffers I’ve allocated before.

  Maybe, there is a better way to solve the problem - allocate one big buffer and pass all the NALs inside ?

• How to batch insert same clip scene at the beginning of multiple videos ?

  13 juin 2013, par FLYqtFLY

  I have been for a few days researching on a suitable auto or semi-automatic way of mass merging files this way. Basically, what I want to achieve is inserting the same clip, before a bunch of other clips.

  In this case I´ve been trying with .flv, .mp4, .avi files (always merging same codecs), and I didn´t succeed after testing all the programs available in both Windows and OSx. Believe me, I´ve tried them all. The only ones which are supposed to handle quite well this quite of tasks are from Videocharge : Watermark Master and Videocharge Studio. None of them could perform correctly the task. Maybe there was some way I could have achieved this by scripting with After Effects or Sony Vegas, I just didn´t find any.

  Now I´m trying to find some way to achieve the same thing either by shell, unix scripting... I don´t care. I just don´t want to mount Ubuntu only for these tasks. I´m not a programmer, but I´m quite stuborn (which sometimes leads me to neverending nights) so I would appreciate some help or guidance from anyone keen and good enough on batch video processing or scripting.

  Right now, the only useful paths I´ve found drive me into either using mencode or ffmpeg through commands, but I am not able to perform the merge on batch. I don´t care about the way to sort the videos out. But taking into consideration that the operation would be performed on hundreds or thousands of videos, it wouldn´t be suitable to have them all in separate folders each accompanied by the "unique" intro clip. I guess that the most logic way would be storing the "bunch" videos in a folder, and the intro clip on the same folder as the encoder or renderer.

  Thanks in advance for any help or guidance,
