  • How to obtain titles and chapters information in DVD ?

    14 décembre 2022, par Tarhan

    I found many question about creating DVD menu using ffmpeg but i did not find any one about programmically access to DVD structure information. When i using libav (or FFmpeg) library i can open DVD image (iso file) and access to video, audio and subtitle streams. But i could not find any API.

    



    I can play video and found information using VLC player (and so libvlc library). But I need to do some processing on audio and subtitle stream programmically. I don't want to split VOBs using tools like SmartRipper, and only then do processing.

    



    Does libav(ffmpeg) contain any API for dealing with DVD menus ? If not can you recommend any other library which can be used to obtain information about title(chapter) start and end time with one frame(sample, AVPacket) accuracy ?

    



    I heard about libdvdnav library but i don't know if it right for me.
I'm new to libav and DVD format internals.

    


  • Discard data stream from container using ffmpeg

    10 décembre 2020, par A.Be

    I am trying to get rid of a data (subtitle) stream within a Mp4 container, using ffmpeg.

    



    Here's the screenshot from ffprobe :

    I tried :

    



     ffmpeg -i test.m4v -acodec copy -vcodec copy -sn nodata.mp4


    



    Data track still there, just moved from stream 0 to stream 2

    



    I tried also :

    



     ffmpeg -i test.m4v -acodec copy -vcodec copy -map 0:1 -map 0:2 no2.mp4


    



    Same result, track still there, just jumped to stream 0:2 no luck.

    



    Any hint ?
Thanks in advance

    


  • How to add chapters to ogg file ?

    22 février 2021, par MayurK

    I am trying to add chapters to a ogg file containing vorbis audio.

    



    From this link I copied the following ffmpeg command.

    



    ffmpeg -threads auto -y -i in.ogg -i metadata_OGG.txt -map_metadata 1 -codec copy out_METADATA.ogg


    



    My metadata_OGG.txt file is as given below.

    



    CHAPTER00=00:00:00.000
CHAPTER00NAME=Chapter 01
CHAPTER01=00:00:05.000
CHAPTER01NAME=Chapter 02
CHAPTER02=00:00:10.000
CHAPTER02NAME=Chapter 03


    



    I am getting the following error.

    



    [ogg @ 00000000006d6900] Unsupported codec id in stream 0
Could not write header for output file #0 (incorrect codec parameters ?): Invalid argument


    



    But if i change -codec copy to -acodec copy there is no error in ffmpeg but the text file is converted to video. i.e. the output file will have a static video frame with the text of metadata_OGG.txt in it. Also, I observe the following log message during conversion.

    



      Stream #1:0 -> #0:0 (ansi (native) -> theora (libtheora))
  Stream #0:0 -> #0:1 (copy)


    



    Anybody please tell me what is going wrong here ?

    



    Also, I would like to know what is the right way to add chapters to ogg. I searched for some tools also. I did not get any.
