  • Added : Support for Chapter sub levels.

    5 octobre 2013, par Grandt
    Added : Support for Chapter sub levels.

    Rev. 2.53 - 2013-10-05
    
* Added : Support for Chapter levels.
    
* Added functions :
    
*  ->subLevel() to indent one level under the current, additional
    
chapters are added under that.
    
*  ->backLevel() to step one level back to the parent of the current
    
level.
    
*  ->rootLevel() to step back to the root of the navMap.
    
*  ->getCurrentLevel() to get the current level indentation (root = 1).
    
*  ->setCurrentLevel(int) to set the current level indentation (1 or
    
less returns to the root, same as ->rootLevel()).
    
* ->buildTOC now reflects this level indentation if present.
    
* ePub250 is otherwise compatible to the previous version, and no
    
modifications are needed if you don't need this feature.

  • How to solve issue for converting ismv file of h264 video codec and aac audio codec ?

    I want to convert transmux ismv file to mp4 format. ISMV file is encoded withe the following ffmpeg detail :

  • Audio object type 3 is not supported

    3 octobre 2013, par Ardoramor

    I am running into an issue with a custom-built ffmpeg. Basically, its a vanilla ffmpeg with x264 and fdk-aac libs enabled. I am feeding an SDP file through ffmpeg API and get the following error while passing the info to avcodec_open2 :

    Audio object type 3 is not supported

    My SDP file :

    v=0
    
o=- 0 0 IN IP4 127.0.0.1

m=application 8206 RTP/AVP 96
    
a=rtpmap:96 smpte336m/10

    The following is the output I get from ffmpeg as I open the input, dump its format, and try to open input streams :

    Format sdp probed with size=2048 and score=50

Stream #0:1, 0, 1/90000: Video: h264, 90k tbr, 90k tbn, 180k tbc  
    

    
Stream #0:2, 0, 1/90000: Data: none, 0/1  

    Audio object type 3 is not supported.

    I also see the error reported for not finding codec parameters for stream 1 :

    Could not find codec parameters for stream 1 (Video : h264) : unspecified size
    Consider increasing the value for the 'analyzeduration' and 'probesize' options

    However, I think that is due to me not running an actual rtp at the moment of the test.

    In any case, what may be the reason for getting audio object type 3 not supported exception ?

    UPDATE - Oct 02, 2013

    Static ffmpeg build gives the following flags :

    Static ffmpeg 2.0.1 build flag output :

    The fdk-aac library version I'm using :

    fdk-aac - 0.1.2

    So it seems that the same .sdp file causes Audio object type 3 error with my build but not with static but I really do not see what causes it (granted I am not an expert with ffmpeg API and may simply miss important details).

    Simplified code for opening .sdp file that doesn't include error checks and logic separation :

    AVFormatContext *inputContext = NULL;
    

    
av_register_all();
    
avformat_network_init();
    

    
avformat_open_input(&inputContext, "test.sdp", NULL, NULL);
    
avformat_find_stream_info(inputContext, NULL);
    

    
int inAudioStreamIdx = av_find_best_stream(inputContext, AVMEDIA_TYPE_AUDIO, -1, -1, NULL, 0);
    
AVStream *st = inputContext->streams[inAudioStreamIdx];
    

    
AVCodecContext *dec_ctx = st->codec;
    
AVCodec *dec = avcodec_find_decoder(dec_ctx->codec_id);
    

    
avcodec_open2(dec_ctx, dec, NULL); // Fails here with Audio object type 3

    Am I opening the sdp input improperly ?
