  • Choppy result from FFMPEG Concatenate

    21 juin 2018, par stonehenge

    I am using this code to merge mp4 files that all have identical encoding, format, etc. My issue is that there is choppiness / flickering at the seams where the videos are combined.
    ffmpeg -f concat -i mylist.txt -c copy output.mp4

    How can I ensure the files merge smoothly ?

    Here is the output from the command prompt.

  • ffmpeg for android, out of memory on encoding h264

    15 juin 2018, par Rafael Lima

    I’m getting an weird error when enconding a video with ffmpeg on android

    Failed to inject frame into filter network: Out of memory

    Althoug is a pretty objective error, I do believe this is some "generic message" for another problem, because the video I used for testing is 17MB and less than 11 seconds length and I’ve sucessfully tested with videos bigger than 200MB and longer than 5min

    This problem happens to any video vertical videos recorded on my phone (the videos were recorded and play fine on my phone but i cant reencode them... other video h264 were encoded fine on same phone)

    this is ffmpeg output

    I detected the problem happens to ANY video with the

    Metadata:
    
      rotate          : 90 (or any value)

    It was suggested to use -noautorotate as workaround and it WORKDED, but this implies in tons of other complications ex :

    -if i decide to apply any filter to the video, it will be applied to the horizontal version but the video will be played at vertical producing a totally different effect

    ex : https://i.stack.imgur.com/R3jXJ.jpg (at this photo the drawtext filter should be placed at bottom line with horizontal text, but as ffmpeg can’t handle the orientation it is missplaced and rotated at runtime producing this vertical message)

    -I checked and if I set -metadata:s:v:0 rotate= while enconding it has no effect ex :

    ffmpeg -i input.mp4 -c copy -metadata:s:v:0 rotate= output.mp4
    will remove the rotate metadata and produce a non rotated video

    BUT
    ffmpeg -i input.mp4 -c:v libx264 -metadata:s:v:0 rotate= output.mp4
    will keep the metadata and the produced video will be played rotated (this behavior was also noticed on the official ffmpeg 4.0 binaries for windows available at ffmpeg website)

    I’M STILL LOOKING FOR A BETTER SOLUTION, THANKS FOR THE HELP

    BUT
    ffmpeg -i input.mp4 -c:v libx264 -metadata:s:v:0 rotate= output.mp4
    will keep the metadata and the produced video will be played rotated (this behavior was also noticed on the official ffmpeg 4.0 binaries for windows available at ffmpeg website)

    I’M STILL LOOKING FOR A BETTER SOLUTION, THANKS FOR THE HELP
