  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • Do I need an AVFormatContext for decoding raw audio data ?

    4 décembre 2023, par CheekyChips

    I am streaming encoded audio data to my program, in raw byte arrays. The audio data could have any encoding but when I receive the data I will know the encoding, sample rate, etc, so I know how to interpret it. Using ffmpeg/libav libraries, I want to decode the audio chunks when I receive them and do some processing with them (e.g. resampling). My question is, since I am getting raw encoded audio data that is not wrapped in a file format, do I still need to create a AVFormatContext and use av_read_frame() to get the encoded AVPacket ? Or should I just create an AVPacket using av_packet_from_data(AVPacket *pkt, uint8_t *data, int size) and manually set the properties like encoding, sample rate, etc ? It is my understanding that AVFormatContext is meant for representing file formats, i.e. wrappers, so I don't know if it would work if I use raw encoded audio data (which I would access through a custom AVIOContext). Also, since I want to support lots of different audio codecs as input, I don't know if the different frame sizes for different codecs will make it difficult to create an AVPacket, if I have the wrong number of samples in my data array, so maybe an AVFormatContext would be better.

    


    Which is the better approach for decoding raw encoded audio chunks - creating an AVFormatContext or AVPackets ?

  • Trancsode and generate waveform data file in ffmpeg with a single command

    19 mai 2019, par user1152226

    I am trying to transcode and generate a waveform data file in the same command. I cannot figure out how to generate 2 output files from a single input. I want an mp4 file, and the waveform data file. The waveform data needs to be generated from the output of the transcoding step (ie, after the stream has already been transcoded)

    The following does not work :

    ffmpeg -i "https://mp3l.jamendo.com/?trackid=862797&format=mp31" -map 0:a -c:a libfdk_aac out1.mp4 -f data data.txt
    
Output file #1 does not contain any stream
