• 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 :

  Duration: 01:28:23.42, start: 0.000000, bitrate: 448 kb/s

  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 :

  ffmpeg -i cc121307pm.rm -map 0:8 -map 0:7 -c:v libx264 -c:a libfaac -b:a 32k test.avi

• How to concat mp4 files using libffmpeg in c program ?

  1er août 2013, par chichien

  I know ffmpeg command line is easy, but how to programmatically implement？ I'm not good at this，here is some code from internet, it is used to convert .mp4 to .ts，and i made some changes，but the audio stream problem persists：

  #include

  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.
