  • WebM Cabal

    8 octobre 2010, par Multimedia Mike — On2/Duck, VP8

    I traveled to a secret clubhouse today to take part in a clandestine meeting to discuss exactly how WebM will rule over all that you see and hear on the web. I can’t really talk about it. But I can show you the cool hat I got :



    Yeah, you’re jealous.

    The back of the hat has an Easter egg for video codec nerds– the original Duck Corporation logo (On2′s original name) :



    Former employees of On2 (now Googlers) were well-represented. It was an emotional day of closure as I met the person — the only person to date — who contacted me with a legal threat so many years ago. He still remembered me too.

    I met a lot of people involved in creating various Duck and On2 codecs and learned a lot of history and lore behind then– history I hope to be able to document one day.

    I’m glad I got that first rough draft of a toy VP8 encoder done in time for the meeting. It was the subject of much mirth.

  • What could change the fps when copying frames from mp4 file to mp4 without reencoding ?

    27 novembre 2012, par theateist

    I try to copy video from in.mp4 to out.mp4 without reincoding. I'm using the code example suggested by pogorskiy here. The copy process success, but the video is played very fast. I checked the fps of both files with MediaInfo. The fps of "in.mp4" is 25 fps and "out.mp4" it 533fps. I don't understand what changing the fps to 533 if I construct outStream from inStream ?

    I hope I explained myself correctly.

  • Codec profile of AAC media file [closed]

    9 janvier 2013, par Pavle

    I need to find out codec profile of some AAC media file. (I want to know if that file iz HE-ACC or some other codec profile).

    I tried with source like this :

    AVFormatContext* pFormatCtx;
    
avformat_open_input(pFormatCtx, input_path, NULL, NULL);
    
..
    
avformat_find_stream_info((*pFormatCtx), NULL);
    
..
    
/* I hope i'll get FF_PROFILE_AAC_MAIN or FF_PROFILE_AAC_LOW or FF_PROFILE_AAC_HE ... */
    
int wanted_profile = pFormatCtx->streams[audio_stream_index]->codec->profile;
    

    
/* but I always get FF_PROFILE_UNKNOWN :( */

    Can anyone help me to find out how to do it, please.
