  • Media contaner which supports uncompressed audio and video

    21 juin 2017, par Denis Kokorin

    I want to produce uncompressed video and audio programmatically and feed it via stdin to ffmpeg.
    I need uncompressed, because I don’t want to encode video and audio in my code.

    I found here the way to create video only file from uncompressed rgb24 input stream. But I do need to create both video and audio.

    Which container supported by ffmpeg can contain uncompressed video and audio ?

  • 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 ?

    EDIT

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

    Command :

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