    Skip buffer update in sub8x8 rd loop

    This commit allows the encoder to skip a few buffer update steps in
    rd_pick_best_mbsegmentation, when early breakout has been triggered
    in the rd_check_segment_txsize. It provides about 1% speed-up for
    bus_cif at 2000 kbps, in the settings of speed 0.

    Special handle on DC only inverse 8x8 2D-DCT

    This commit enables a special handle for the 8x8 inverse 2D-DCT,
    where only DC coefficient is quantized to be non-zero. For bus_cif
    at 2000 kbps, it provides about 1% speed-up at speed 0.

  • Converting Real Media with ffmpeg

    7 août 2013, par Eric Arenson

    I have a number of old crusty Real Media files I need to convert and was hoping to write a script to batch process them. I'm able to do a Real Media -> AVI conversion with FFMpegX, but when I try to replicate the conversion with ffmpeg, it always errors out with something like :

    [avi @ 0x10084fa00] Too large number of skipped frames 117425 > 60000

    It may have something to do with the funky format of these Real Media files :

    Does anyone have any tips on either how to find out what FFMpegX is doing to make the conversion work, or a better way to go about using ffmpeg to do this ?

    EDIT

    Including the ffmpeg command (thank you to @Mondain for teaching me about the stream mapping !) and output :
