  • How to use hardware acceleration with ffmpeg

    16 juin 2014, par ixSci

    I need to have ffmpeg decode my video(e.g. h264) using hardware acceleration. I’m using the usual way of decoding frames : read packet -> decode frame. And I’d like to have ffmpeg speed up decoding. So I’ve built it with --enable-vaapi and --enable-hwaccel=h264. But I don’t really know what should I do next. I’ve tried to use avcodec_find_decoder_by_name("h264_vaapi") but it returns nullptr.
    Anyway, I might want to use others API and not just VA API. How one is supposed to speed up ffmpeg decoding ?

    P.S. I didn’t find any examples on Internet which uses ffmpeg with hwaccel.

  • av_find_stream_info works OK with file, not with pipe

    14 décembre 2016, par Aliza

    I have the following code :

    av_register_all();
    
pFormatCtx = avformat_alloc_context();
    
const char* input = "pipe:";
    
AVInputFormat* iFormat = av_find_input_format("mpegts");
    
if ( avformat_open_input(&pFormatCtx, input, iFormat, NULL) != 0 )
    
         return -1;
    
int res = av_find_stream_info(pFormatCtx);

    when my input is a regular file, this works nicely and pFormatCtx is populated with the streams in the file. However, when i set input to "pipe :", av_find_stream_info returns with -1.

    I am using the same file and piping it by running
    cat mpeg.ts | myApp

    Any ideas ?

    Thanks,
    Aliza

  • ftp upload then loop

    23 juillet 2012, par thevoipman

    I have a minor bash script loop I'm trying to learn and accomplish but it's giving me a hard time to comprehend with all the readings I've done.

    I am uploading to a ftp server, then I want to check to see if the upload went through successfully by using wget spider method. If it returns OK then we're good, if not then I want to redo the ftp upload once more.

    The code I have below are based on my research and learning from here. If I could be doing this better, please help me revise it so I can learn from it.

    Thanks again in advance :

    for ((i = 0 ; i < 1 ; i++ )); 
    
do 
    
    wget_output=$(wget -q --spider "http://$FTP_HOST/test.jpg")
    
    if [ $? -ne 0 ]; 
    
    then
    

    
        ftp -in $FTP_HOST &lt;<endftp user="user" binary="binary" put="put" bye="bye" endftp="endftp" else="else" echo="echo" code="code" fi="fi" done="done"></endftp>code>

    My errors when executing is :

    line 28: syntax error: unexpected end of file
