  • How can I use ffmpeg with h264_qsv?

    29 April 2018, by Ubunkun

    I’ve installed the "Intel MediaServer Studio Essentials 2018R1". And I complied ffmpeg with h264_qsv.

    When I tried to use ffmpeg with h264_qsv, the errors occurred.

    $ ffmpeg -y -i ffefc5a076d93be46df1ff8674592d39.mp4 -vframes 2000 -b:v 2000K -vcodec h264_qsv -preset slow out00.mp4

    I don’t know where is wrong. If input file is wrong, I can change input file. I have not succeeded in running ffmpeg with h264_qsv.
    I would appreciate it if somebody can help me on how to run ffmpeg with h264_qsv.

    But it can’t work. The access.log appears just one line.

    192.168.1.121 [02/May/2018:21:52:39 +0900] PUBLISH "hls" "test2" "" - 580840 753 "" "FMLE/3.0 (compatible; Lavf57.55" (21s)

    There is no "hls2" PUBLISH on access log.

    When I tried to run the ffmpeg command line while nginx is running, it was succeed.

    Why ffmpeg called by nginx doesn’t work? If you have any solution, let me know.

  • FFMPEG: Impossible to convert between the formats supported by the filter

    30 April 2018, by Netheme

    Trying to decode & encode the video in FFMPEG on my GPU. Using this command:

    ffmpeg -y -c:v mpeg2_cuvid -vsync 0 -deint 2 -drop_second_field 1 -surfaces 10 -i 'udp://@227.10.20.149:1234?fifo_size=100000000'  -map i:0x12c -r 25 -filter fps=30,scale_npp=640:360:format=same:interp_algo=lanczos -aspect 16:9 -g 96 -vcodec h264_nvenc -b 400K -minrate 400k -maxrate 400k -f mpegts 'udp://@239.0.0.12:1000?overrun_nonfatal_option=1'

    Thanks for tips.
