  • FFMpeg/libav set SEI unregistered user message per video frame

    17 décembre 2018, par maxhap

    I’m trying to set the SEI unregistered user message on a per video frame basis. I notice that libav has a H264MetadataContext structure which
    contains a const char *sei_user_data field. This seems to be exactly what I’m looking for. After poking around in the FFMpeg code I notice
    this structure is wrapped within the private data of the AVBSFContext. My knowledge is extremely limited so at this point I’m looking for an example
    or explanation on how to correctly access the H264MetadataContext structure. I presume I need a bit stream filter (based on the naming), but can’t
    find any examples of setting the H264MetadataContext.

    Can anyone help me with an explanation, code snippet or point me to an example I might have missed/overlooked ?

    Any general advice would also be appreciated. I have checked the few similar questions here on stackoverflow, they don’t seem to have any solid answers or explanations though (maybe due to my lack of understanding).

    Thanks in advanced !

  • How to implement HTTP Live Streaming server on Unix ?

    5 septembre 2012, par alex

    I just realized that Apple required HTTP Live Streaming in order to view videos in iPhone apps. I was not aware of this before... I am now trying to understand what this involves so I can decide whether I want to do the work and make the videos available in 3G or limit video playing to users who are connected to wi-fi.

    I read the overview provided by Apple, and now understand that my server needs to segment and index my media files. I also understand that I don't have to host the content to be able to stream it (I can point to a video hosted somewhere else, right ?).

    What's not clear to me at this point is what to implement on my server (Ubuntu Hardy) to do the actual segmenting and indexing on the fly (once again, I do not host the videos I want to serve).

    I found a link explaining how to install FFmpeg and X264, but I don't know if this is the best solution (since I have an Ubuntu server, I can't use the Apple Live Streaming tools, is it correct ?). Also, I do not understand at which point my server knows that a video needs to be converted and starts the job...

    Any feedback that could help me understand exactly what to do on the server side to be able to stream videos on my iPhone app in 3G would be greatly appreciated ! (Oh, and just it makes any difference, my app back-end is in Rails)
