问题 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 Stream #0:0:
