  • video preview from remote mp4 [h264] file

    20 novembre 2015, par sathia

    I was trying to make a video preview from a remote video (smaller size, short clip and no audio. you get the idea)

    By knowing the video duration, and bitrate (constant) is rather easy to make several byte-range requests in order to fetch chunks of it.

    Once all the needed chunks are downloaded I use the "concat" method of ffmpeg to make a single video (this is in order to avoid to download all the video locally)

    well, technically it all works perfectly the problem is that most of the chunks I download have pretty severe aberrations, and I mean, it’s usually all green and pixelated, rubbish.

    Is this a limit on the h264 protocol or I should maybe find the first keyframe and start from there (on each chunk of course) ? thanks

  • RTP-Server in Android 4.0 and above

    9 juin 2013, par PowerPC

    Working on Android 4.0+ above.

    I am in process of analyzing ways to live stream my camera video to Window PC using RTP , encoding MPEG-2.

    1. Is there readily available "rtp-server" in android 4.0+ ?

    2. Is following true: : "The Android platform lacks support for
      streaming protocol, which makes it difficult to stream live audio /
      video to Android enabled devices." extracted from website

    3. Currently I analyzed used the ffserver from the ffmpeg
      libraries, but the FPS is < 5. which is far slow. Did any one
      explored other solution which has more FPS ?

    4. Did anybody tried using StageFright for same ? Capturing raw data
      from camera and sending it to stagefright framework for encoding and
      then streaming the same using RTP ??

    Many Thanks.

    avformat/mp3dec : optimize mp3_seek() for dir < 0

    this minimizes the amount of protocol seeks and reading needed in that case
