    23 mai 2012, par user1320885

    Right now I am making a Facebook application for iOS. When a make a Facebook request, it returns some videos. I need help and I can only find things online about uploading videos. So my question is how would I play those Videos ?? Is there any way to return the videos in a preferred video format for iOS. I understand that you need to use ffmpeg is that true and if so can someone help me implement this ??

    Thanks,

  • FFMPEG Library MP3 Encoder

    13 mars 2013, par David Tay

    Does the ffmpeg library come with an MP3 encoder ?

    This :

    AVCodec *pCodec = avcodec_find_encoder(AV_CODEC_ID_MP3);

    always returns null. I also tried AV_CODEC_ID_MP3ADU and AV_CODEC_ID_MP3ON4, they too return null. The only encoding codec I've found is AV_CODEC_ID_MP2.

    Any help appreciated

  • Initializing hwaccel_context in libavcodec

    3 janvier 2018, par dloman

    I am trying to get hardware accelerated video working using libavcodec. I am using the hw_decode.c example as a starting point and am unable to get it to work. both AVCodecContext->hwaccel and AVCodecContext->hwaccel_context are NULL

    I belive some part of the hwaccel is working as I see the output

    libva info: VA-API version 0.39.0
    
libva info: va_getDriverName() returns 0
    
libva info: Trying to open /usr/lib/x86_64-linux-gnu/dri/i965_drv_video.so
    
libva info: Found init function __vaDriverInit_0_39
    
libva info: va_openDriver() returns 0

    Which is the same as when I run

    ffmpeg -hwaccel vaapi -hwaccel_device /dev/dri/renderD128 -hwaccel_output_format vaapi -i input.mpg -f null -

    but immediately after that I get the following error message

    [h264 @ 0x1df2cc0] Hardware acceleration context (hwaccel_context) does not exist.
    
Failed to get HW surface format.
    
[h264 @ 0x1df2cc0] decode_slice_header error
    
[h264 @ 0x1df2cc0] no frame!

    I looked at the similar question and the answer to this shows how to get a AVCodecContext->hwaccel. But even with the AVCodecContext->hwaccel being a valid VAApih264 decoder I still get the same error message.

    How do I initialize a AVCodecContext->hwaccel_context and after that what else do I need to do to get hardware accelerated video working in ffmpeg ?
