• Invalid frame dimension, invalid data found when processing input, muxing overhead : unknown when concatting old VOB files | FFMPEG

  9 mars 2023, par Victor Hartman

  I am dealing with multiple errors which I am not able to resolve. I am trying to concat 4 old VOB files to a mp4. Using command (already solved a 'pts has no value error') :

  


  .\ffmpeg.exe -fflags +genpts -f concat -i .\files.txt -c copy output.mp4


  


  files.txt looks like this :

  


  file 'VTS_01_1.VOB'
file 'VTS_01_2.VOB'
file 'VTS_01_3.VOB'
file 'VTS_01_4.VOB'


  


  Output looks like this :

• Cannot stream video from VLC docker

  4 avril 2023, par Snake Eyes

  I have Dockerfile :

  


  FROM fedora:34

ARG VLC_UID="1000"
ARG VLC_GID="1000"

ENV HOME="/data"


RUN groupadd -g "${VLC_GID}" vlc && \

    dnf install -y libbluray-bdj && \
    dnf clean all

USER "vlc"

WORKDIR "/data"

VOLUME ["/data"]

ENTRYPOINT ["/usr/bin/cvlc"]


  


  And then run :

  


  docker run -d -v "d:\path":/data -p 8787:8787 myrepo/myvlc:v1 file:///data/Sample.mkv --sout '#transcode {vcodec=h264,acodec=mp3,samplerate=44100}:std{access=http,mux=ffmpeg{mux=flv},dst=0.0.0.0:8787/stream.flv}'


  


  I get error :

  I mention that I'm using cvlc and I can't stream that mkv file.

  


  I tried as well --sout '#transcode{scodec=none}:http{mux=ffmpeg{mux=flv},dst=:8787/}' but same errors.

  


  How can I solve it ?

  The resultant video can play the first part of the video correctly, then the video players either skips directly to the end of the video (MPC-HC), or don't render anything at all while timer passes as normal (VLC).

  


  My impression of the concat is that it requires all videos to have the same spec, which I think my input achieved (all the "Steam #0:0", etc, line matches). I only see the following difference, which I assumed that should be okay :

  


  

  1. Metadata are different both for the whole input (e.g. "major_brand") and for each stream (e.g. "encoder"). I assumed that metadata won't affect the processing.

  


  2. The order of video/audio streams are different in the two inputs : the 1st input file has audio then video ; the 2nd input file has video then audio. I assumed that ffmpeg knows the difference and won't concat a video stream to an audio stream.
