    ffmpeg -loglevel debug -rtsp_transport tcp -i rtsp://192.168.1.13:1935 -rtsp_transport tcp -c:v copy -f rtsp rtsp://127.0.0.1:1935/live/stream


    


    but this usage can connect to the host and reads the packets from the host but it hangs when trying to connect to the local host :

  • Why is ffmpeg executable so much faster than using libfdk_aac directly ?

    3 février 2016, par lancejabr

    When I encode a wav file to AAC using the ffmpeg executable (using libfdk_aac and setting -threads 1), the process completes several times faster than when I use the AAC encoding example provided by the libfdk_aac library itself. I looked at the code and the central loop in libfdk_aac is almost identical to the aac_encode_frame method in the ffmpeg source.

    Anyone know why the executable would be so much faster ? I’m looking into compilation options but we’re talking like 8x speedup so I don’t think it’s just putting -O3 on there... Does ffmpeg encode multiple buffers at once even when there is only one thread ?

  • Docker run cannot find existing file ?

    11 juillet 2023, par dexonter

    I am trying to run this command to test if the gpu is being recognized

    


    docker run --rm --device /dev/dri:/dev/dri jrottenberg/ffmpeg:5.1.2-vaapi2004 -hwaccel vaapi -hwaccel_output_format vaapi -i /root/Server_transcoder/bbb_sunflower_1080p_30fps_normalORIG.mp4 -c:v h264_vaapi /tmp/example.mp4


    


    And it errors out with : /root/Server_transcoder/bbb_sunflower_1080p_30fps_normalORIG.mp4: No such file or directory

    


    The file exists in there and the path is not misspelled - I checked like 10 times

    


    What could be the problem here ?? I am clueless
