  • FFmpeg av_hwdevice_ctx_create returns ENOMEM

    4 mars 2021, par lnogueir

    I am trying to perform h264 video encoding on a GPU using the ffmpeg's vaapi library.

    


    I have been following this example from ffmpeg Github repo.

    


    It fails for me here :

    


    AVBufferRef* vaapi_encoder;
int err = av_hwdevice_ctx_create(&vaapi_encoder, AV_HWDEVICE_TYPE_VAAPI,
                                 NULL, NULL, 0);


    


    This returns -12, which maps to ENOMEM (out of memory) error, but that doesn't make sense to me because I have plenty of memory.

    


    For reference, this is my output after running 'vainfo' :

    


    libva info: VA-API version 1.7.0
libva info: Trying to open /usr/lib/x86_64-linux-gnu/dri/iHD_drv_video.so

  • php fread returns empty after one time of execution for popen

    20 avril 2021, par Hamed

    I'm trying to get real-time output from ffmpeg command with popen, but it returns empty after one time of execution in the loop.

    


    &lt;?php&#xA;&#xA;$a = popen(&#x27;ffpb -i mymovie.mp4 -vf subtitles=subtitles.srt mysubtitledmovie.mp4 2>&amp;1&#x27;, &#x27;r&#x27;);&#xA;&#xA;&#xA;while (true) {&#xA;    $b = fread($a, 2096);&#xA;&#xA;    var_dump($b) . "<br />\n";&#xA;&#xA;    ob_flush();&#xA;    flush();&#xA;&#xA;    sleep(1);&#xA;}&#xA;

    &#xA;

    The output : :

    &#xA;

    mymovie.mp4:   0%|          | 0/61080.0 [00:00&lt;?, ? frames/s]"&#xA;string(105) "Unexpected exception: &#x27;ascii&#x27; codec can&#x27;t encode characters in position 43-47: ordinal &#xA;not in range(128)&#xA;"&#xA;string(0) ""&#xA;string(0) ""&#xA;string(0) ""&#xA;
