  • FFMPEG concat videos

    10 juin 2015, par Maverick

    I am unable to concat two videos using FFMPEG. The command fails on the two special videos.

    Video 1 :
    First video is generated from the image using the following command :

    ffmpeg -loop 1 -i 20150608_162807.jpg -c:v libx264 -t 3 -pix_fmt yuv420p out.mp4

    I tried to concat the above video but it did not work so, I thought to add an audio to check if it will work.

    ffmpeg -f lavfi -i aevalsrc=0 -i out.mp4 -shortest -c:v copy -c:a aac -strict experimental silent.mp4

    but even with that it did not work.

    Video 2 :
    Second video is captured from the device camera.

    Both of these videos can be downloaded from here.

    Update 1 :
    The concat protocol doesn’t work with mp4s. So, I tried the other approaches.

    ffmpeg -i input1.mp4 -c copy -bsf:v h264_mp4toannexb -f mpegts intermediate1.ts
    
ffmpeg -i input2.mp4 -c copy -bsf:v h264_mp4toannexb -f mpegts intermediate2.ts 
    
ffmpeg -i "concat:intermediate1.ts|intermediate2.ts" -c copy -bsf:a aac_adtstoasc output.mp4

    but still it didn’t work.

    Update 2 :
    I have also used concat demuxer approach but it did not work as well.

  • Embedding timed text metadata in MP4

    10 juin 2015, par Steve Robinson

    Is it possible to manually embed timed text metadata into MP4 files ?
    I have a TTML / SRT file with the metadata. I just need to embed the text data without doing any encoding the video / audio.

    EDIT :
    We used to do the metadata injecting using on Wowza server which we use for live streaming. What I need to do is manually inject the metadata in to prerecorded MP4 files without running the video through Wowza.

    Here is one such video file that was processed by Wowza :

    Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'metadata-back.mp4':

    Now if I run the command ffmpeg -i new-meta.mp4 -i sub.srt -c copy -c:s mov_text -movflags +faststart out.mp4 and if I run ffmpeg -i out.mp4, I get this :

    Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'out.mp4':

    Metadata:
    
      handler_name    : SubtitleHandler

    Now as you can see the text is embedded with a different codec (is this the right term ?). Also I dont see an audio track as well.

    Hope my question is clear enough. I need a way to embed metadata (from srt / ttml) into an MP4 video it should be embedded in amf format (again is this the right term ?)
