  • playing multiple intervals of a video [on hold]

    6 juin 2018, par gagan singh

    I have a video. I know how to play one interval say 10s-20s.

    How do I play multiple intervals, say 10s-20s then immediately 30s-50s and so on ?

    I am also fine with running ffmpeg -c once to extract the combined stream of my time ranges.

    In one of the ffmpeg query, some one mentioned edit list support in some video players. What is that ?

    I am fine with playing the video with any linux video player, vlc, mplayer etc.
    anything which can play something like the following.

    player —intervals=10-20,30-50 video.mp4

    basically for a movie, I want to play selected intervals of the movie, instead of the whole movie.

    I hope this makes my question clearer.

  • What are the APIs for hardware accelerated video decoding in phones ?

    11 janvier 2012, par cloudraven

    I have seen many smartphones coming with hardware accelerated video decoding supporting mpeg2 and h264, but unlike in desktop and laptop systems, it is not clear to me how to interact with the hardware acceleration.
    For desktops/laptops there is DXVA, VDPAU and OpenMax.
    Is any of those supported in Mobile phones ? I think OpenMax is, but I am not sure of how widely supported it is.

    Is anyone familiar with what is usually used to write hardware accelerated media players and decoders for platforms like Snapdragon, Tegra 2 or Omap 4 running Android or Windows Phone ?
    I know that ffmpeg can be compiled for arm and I wonder what kind of hardware video acceleration it supports on that platform.

  • FFMEPG Audio Encoding, How to get optional frame_size of the CodecContext and get right ouput

    23 octobre 2014, par 程栋彬

    I’m trying to encode pcm format audio using ffmpeg, because the pcm data is of FLTP format, I use audio codec AV_CODEC_ID_AC3 or AV_CODEC_ID_MP3, when I use avcodec_open2(pCodecCtx,pCodec), the pCodecCtx->frame_size was set by this function, for example, it is set as 1536. But the pcm data I get was saved by frame_size = 512. I don’t to do the data transfer, so I just change pCodecCtx->frame_size to 512 after avcodec_open2(), but the output encoded audio sounds wrong.

    So how to encode audio with optional frame_size when the input is pcm data saved in FLTP format ?
