  • ffmpeg - How to determine if -movflags faststart is enabled ? PHP

    6 juillet 2017, par IIIOXIII

    While I am able to encode an mp4 file which I can play on my local windows machine, I am having trouble encoding files to mp4 which are readable when streaming by safari, etc.

    After a bit of reading, I believe my issue is that I must move the metadata from the end of the file to the beginning in order for the converted mp4 files to be streamable.

    To that end, I am trying to find out if the build of ffmpeg that I am currently using is able to use the -movflags faststart option through php - as my current outputted mp4 files are not working when streamed online.

    This is the way I am now echoing the -help, -formats, -codecs, but I am not seeing anything about -movflags faststart in any of the lists :

    exec($ffmpegPath." -help", $codecArr);
    
for($ii=0;$iibr>';
    
}

    Is there a similar method of determining if -movflags fastart is available to my ffmpeg build ? Any other way ? Should it be listed with any of the previously suggested commands ? -help/-formats ?

    Can someone that knows it is enabled in their version of ffmpeg check to see if it is listed under -help or -formats, etc.?

    TIA.

  • 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

  • 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 ?
