  • Extract number of frames without using shell-True

    26 mars 2022, par petrush

    I have the following code that extract number of frames from video :

    &#xA;

    filename = "test.mp4"&#xA;video_path = os.path.join(os.getcwd(), filename)&#xA;with open(video_path, "rb") as file:&#xA;    cmd = f&#x27;ffmpeg -i {video_path} -r 10 -q:v 3 -s 1x1 -f image2 -update 1 - >/dev/null&#x27;&#xA;    proc = sp.Popen(cmd, stdout=sp.PIPE, stderr=sp.PIPE, shell=True)&#xA;    (stdout, stderr) = proc.communicate()&#xA;&#xA;    # i.e: &#x27;frame= 2062 fps=966 q=3.0 Lsize=N/A time=00:10:34.46 bitrate=N/A dup=1049 drop=3563 speed= 297x&#x27;&#xA;    decoded = stderr.decode(&#x27;utf-8&#x27;)&#xA;    frame_count_line = decoded.splitlines()[-2]&#xA;    m = FRAME_COUNT_REGEX.search(frame_count_line)&#xA;    if m:&#xA;        print(int(m.groups()[0]))&#xA;

    &#xA;

    but because of security reasons I want to remove shell=True parameter.&#xA;Unfortunately after that the code above throws :

    &#xA;

    FileNotFoundError: [Errno 2] No such file or directory&#xA;

    &#xA;

    Please help to fix it

  • Revision 11abab356e : Refactor inter mode rate-distortion search This commit separates the rate-disto

    28 septembre 2013, par Jingning Han

    Changed Paths :
     Modify /vp9/encoder/vp9_encodeframe.c


     Modify /vp9/encoder/vp9_encodemb.h


     Modify /vp9/encoder/vp9_onyx_if.c

    Refactor inter mode rate-distortion search

    This commit separates the rate-distortion optimization loop of
    superblocks from that of sub8x8 blocks. This allows better design
    rate-distortion optimization search loop for each setting. It also
    removes the use of SPLITMV and I4X4_PRED therein.

    No performance change in speed 0 settings. For bus@CIF at 2000kbps,
    the speed 1 runtime goes from 48009ms to 43894ms (about 10% faster).
    The overall compression performance on derf changed by -0.021%.

    Speed 2 runtime goes from 27114ms to 28700ms (6% slower), while the
    overall coding efficiency goes up by 1.629% for derf, 1.236% for yt.
