Converting Real Media with ffmpeg

22 avril 2018, 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 ?

How to reduce the bitrate loss from video processing via FFMPEG ?

so I use this code to add an intro, outro and watermark to a video but the final result has a loss in bitrate from 2108 bps to 705 bps, how can I keep the bitrate in the 2000 bps range ?

Thank you for your help.

current version of ffmpeg3.3.2 encode twice time of my video,the duration last two times long

20 juin 2017, par jimmy

I have a video with 00:01:41.46 play time,and transcode it perfect with ffmpeg-2.1.1,but when I upgrade FFmpeg version to 3.3.2 and compile it with the same compile option and same transcode option as 2.1.1 version used, I got a video with 00:03:21.82 long, I played that video to see what was added after 1:41.46, and find that it just repeat the video from the beginning with no audio, I find out no idea to this issue, it seems to be a bug that FFmpeg introducing, anyone help me !

here is the log that I had transcoded with ffmpeg 3.3.2 :
