  • 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" (...)

  • torchaudio.io.StreamReader doesn't throw error when seeking to time stamp more than the duration of audio file

    27 mars 2023, par lokesh

    I am trying to get the audio chunk of audio file between specific start time and end time

    


    Consider a audio of duration 10 seconds. Now i need to get chunk from 4 sec to 7 sec

    


    torchaudio.info doesn't give correct num_frames for io.BytesIO flac audio file. So there is no way to find the total number of frames in the given audio to check for out of bounds start offset
Ref : https://github.com/pytorch/audio/issues/2524

    


    What I did to get the chunk of audio with start and end offsets.

    


    def read_audio(audio_file, start, end):
    audio_file.seek(0)
    reader = StreamReader(audio_file)
    sample_rate = int(reader.get_src_stream_info(reader.default_audio_stream).sample_rate)

    reader.seek(start * sample_rate)
    reader.add_basic_audio_stream(frames_per_chunk=(end - start) * sample_rate)

    return list(reader.stream())[0].pop()


    


    This is working as intended for start time less than the duration of audio file. But when we give the start time more than the duration of audio file, It doesn't throw error or return empty tensor.
Is there any way to know the given offsets are out of bounds.

    


  • GStreamer on Android

    9 décembre 2014, par DiscGolfer

    Can anyone give me any tips on getting GStreamer to work on Android. I have never used it before and I would like to use it with FFmpeg (I already have FFmpeg compiled and works fine on Android). I would just like to use GStreamer to help with some of the processing as learning the FFmpeg API is somewhat of a nightmare haha. Thanks in advance for any help at all !

  • Installing openCV with anaconda on ubuntu

    6 décembre 2017, par Akash Sethi

    I’m trying to use the openCV library with anaconda (Python) , i am able to import the cv2 package but nothing has been able to access a .mp4 file so far. It’s an issue with the ffmpeg thing which i have no idea about. I cannot post code right now since I’m using my phone. But if anyone can give me a Linux script or a tutorial that can help me work with openCV on python to be able to analyze mp4 videos with h264 encoding , that would be great
