  • wrong ffmpeg version for xuggler

    13 décembre 2011, par kerel

    I am trying to get Xuggle working on Ubuntu.
    This is however my first time using a Unix system.

    After installing Xuggle and correcting the PATH files I tried some very simple code from tutorials at the xuggle website. But once I attempt to debug my code, it stops and eclipse says

    Suspended (exeption IllegalArgumentException)

    and refers to line 488 of MediaReader.readPacket()

    After searching possible explanations I found that my FFMPEG version was not the version Xuggle needs. When I test my FFMPEG version from command line with
    $ ffmpeg /invalid/file/ it displays --extra-version='4:0.7.2-1ubuntu1' but according to the xuggle site the --extra-version= should include the word "xuggle". Following their installation procedures does not change anything.

    I downloaded the source code from SVN, which includes a ffmpeg folder. I assume this is the ffmpeg version I need. I have no clue however what to do with this folder.

    question is : how do I get my ffmpeg version to the xuggle compatible ffmpeg version ?

  • avcodec/x86/videodsp : Small speedups in ff_emulated_edge_mc x86 SIMD.

    avcodec/x86/videodsp : Small speedups in ff_emulated_edge_mc x86 SIMD.
    

    Don’t use word-size multiplications if size == 2, and if we’re using
    SIMD instructions (size >= 8), complete leftover 4byte sets using movd,
    not mov. Both of these changes lead to minor speedups.

  • FFMPEG 'Fontconfig error : Cannot load default config file' error Windows

    30 décembre 2024, par Merel

    I am trying to make a short video in FFMPEG, where a word stays on screen for the duration of the video (0.5s). My FFMPEG code looks like this :

    &#xA;&#xA;

    ffmpeg -f lavfi -i color=c=white:s=320x240:d=0.5 -vf "drawtext=fontfile= ‘c\:\Windows\fonts\calibri.ttf&#x27;:fontsize=18:  fontcolor=black:x=(w-text_w)/2:y=(h-text_h)/2:text=&#x27;word&#x27;" output.mp4

    &#xA;&#xA;

    However, I keep getting the following error (see below for full output) :

    &#xA;&#xA;

    Fontconfig error: Cannot load default config file &#xA;[Parsed_drawtext_0 @ 000001c2918cef00] Using "C:/Windows/fonts/mingliub.ttc"&#xA;

    &#xA;&#xA;

    I figured it had something to do with the path to the font file. I also tried copying the font file to my FFMPEG map and map the font path to the FFMPEG directory :

    &#xA;&#xA;

    ffmpeg -f lavfi -i color=c=white:s=320x240:d=0.5 -vf&#xA;"drawtext=fontfile=‘C:\FFMPEG\bin\calibri.ttf&#x27;:fontsize=18: &#xA;fontcolor=black:x=(w-text_w)/2:y=(h-text_h)/2:text=&#x27;word&#x27;" output.mp4&#x27;&#xA;

    &#xA;&#xA;

    This doesn't work either. I do get an output video.mp4 video, but the font is wrong. Here is the full output I get. It is the same for both code examples above :

    &#xA;&#xA;

     c:\FFMPEG\bin>ffmpeg -f lavfi -i color=c=white:s=320x240:d=0.5 -vf "drawtext=fontfile= ‘c\\:\\\Windows\\\fonts\\\calibri.ttf&#x27;:fontsize=18:  fontcolor=black:x=(w-text_w)/2:y=(h-text_h)/2:text=&#x27;word&#x27;" output.mp4&#xA;ffmpeg version N-93234-g2e67f751b5 Copyright (c) 2000-2019 the FFmpeg developers&#xA;  built with gcc 8.2.1 (GCC) 20190212&#xA;  configuration: --enable-gpl --enable-version3 --enable-sdl2 --enable-fontconfig --enable-gnutls --enable-iconv --enable-libass --enable-libdav1d --enable-libbluray --enable-libfreetype --enable-libmp3lame --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libopenjpeg --enable-libopus --enable-libshine --enable-libsnappy --enable-libsoxr --enable-libtheora --enable-libtwolame --enable-libvpx --enable-libwavpack --enable-libwebp --enable-libx264 --enable-libx265 --enable-libxml2 --enable-libzimg --enable-lzma --enable-zlib --enable-gmp --enable-libvidstab --enable-libvorbis --enable-libvo-amrwbenc --enable-libmysofa --enable-libspeex --enable-libxvid --enable-libaom --enable-libmfx --enable-amf --enable-ffnvcodec --enable-cuvid --enable-d3d11va --enable-nvenc --enable-nvdec --enable-dxva2 --enable-avisynth --enable-libopenmpt&#xA;  libavutil      56. 26.100 / 56. 26.100&#xA;  libavcodec     58. 47.102 / 58. 47.102&#xA;  libavformat    58. 26.101 / 58. 26.101&#xA;  libavdevice    58.  6.101 / 58.  6.101&#xA;  libavfilter     7. 48.100 /  7. 48.100&#xA;  libswscale      5.  4.100 /  5.  4.100&#xA;  libswresample   3.  4.100 /  3.  4.100&#xA;  libpostproc    55.  4.100 / 55.  4.100&#xA;Input #0, lavfi, from &#x27;color=c=white:s=320x240:d=0.5&#x27;:&#xA;  Duration: N/A, start: 0.000000, bitrate: N/A&#xA;    Stream #0:0: Video: rawvideo (I420 / 0x30323449), yuv420p, 320x240 [SAR 1:1 DAR 4:3], 25 tbr, 25 tbn, 25 tbc&#xA;Stream mapping:&#xA;  Stream #0:0 -> #0:0 (rawvideo (native) -> h264 (libx264))&#xA;Press [q] to stop, [?] for help&#xA;Fontconfig error: Cannot load default config file&#xA;[Parsed_drawtext_0 @ 00000291ad7def00] Using "C:/Windows/fonts/mingliub.ttc"&#xA;[libx264 @ 00000291af0ef180] using SAR=1/1&#xA;[libx264 @ 00000291af0ef180] using cpu capabilities: MMX2 SSE2Fast SSSE3 SSE4.2 AVX FMA3 BMI2 AVX2&#xA;[libx264 @ 00000291af0ef180] profile High, level 1.3, 4:2:0, 8-bit&#xA;[libx264 @ 00000291af0ef180] 264 - core 157 r2935 545de2f - H.264/MPEG-4 AVC codec - Copyleft 2003-2018 - http://www.videolan.org/x264.html - options: cabac=1 ref=3 deblock=1:0:0 analyse=0x3:0x113 me=hex subme=7 psy=1 psy_rd=1.00:0.00 mixed_ref=1 me_range=16 chroma_me=1 trellis=1 8x8dct=1 cqm=0 deadzone=21,11 fast_pskip=1 chroma_qp_offset=-2 threads=6 lookahead_threads=1 sliced_threads=0 nr=0 decimate=1 interlaced=0 bluray_compat=0 constrained_intra=0 bframes=3 b_pyramid=2 b_adapt=1 b_bias=0 direct=1 weightb=1 open_gop=0 weightp=2 keyint=250 keyint_min=25 scenecut=40 intra_refresh=0 rc_lookahead=40 rc=crf mbtree=1 crf=23.0 qcomp=0.60 qpmin=0 qpmax=69 qpstep=4 ip_ratio=1.40 aq=1:1.00&#xA;Output #0, mp4, to &#x27;output.mp4&#x27;:&#xA;  Metadata:&#xA;    encoder         : Lavf58.26.101&#xA;    Stream #0:0: Video: h264 (libx264) (avc1 / 0x31637661), yuv420p, 320x240 [SAR 1:1 DAR 4:3], q=-1--1, 25 fps, 12800 tbn, 25 tbc&#xA;    Metadata:&#xA;      encoder         : Lavc58.47.102 libx264&#xA;    Side data:&#xA;      cpb: bitrate max/min/avg: 0/0/0 buffer size: 0 vbv_delay: -1&#xA;[Parsed_color_0 @ 00000291af0aa840] EOF timestamp not reliable&#xA;frame=   13 fps=0.0 q=-1.0 Lsize=       2kB time=00:00:00.40 bitrate=  43.9kbits/s speed=4.27x&#xA;video:1kB audio:0kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: 84.991570%&#xA;[libx264 @ 00000291af0ef180] frame I:1     Avg QP: 9.22  size:   306&#xA;[libx264 @ 00000291af0ef180] frame P:3     Avg QP:11.33  size:    20&#xA;[libx264 @ 00000291af0ef180] frame B:9     Avg QP:12.67  size:    14&#xA;[libx264 @ 00000291af0ef180] consecutive B-frames:  7.7%  0.0%  0.0% 92.3%&#xA;[libx264 @ 00000291af0ef180] mb I  I16..4: 98.7%  0.0%  1.3%&#xA;[libx264 @ 00000291af0ef180] mb P  I16..4:  0.0%  0.0%  0.0%  P16..4:  0.0%  0.0%  0.0%  0.0%  0.0%    skip:100.0%&#xA;[libx264 @ 00000291af0ef180] mb B  I16..4:  0.0%  0.0%  0.0%  B16..8:  0.0%  0.0%  0.0%  direct: 0.0%  skip:100.0%&#xA;[libx264 @ 00000291af0ef180] 8x8 transform intra:0.0%&#xA;[libx264 @ 00000291af0ef180] coded y,uvDC,uvAC intra: 1.0% 0.0% 0.0% inter: 0.0% 0.0% 0.0%&#xA;[libx264 @ 00000291af0ef180] i16 v,h,dc,p: 92%  1%  7%  0%&#xA;[libx264 @ 00000291af0ef180] i4 v,h,dc,ddl,ddr,vr,hd,vl,hu: 39%  3% 42%  2%  5%  5%  2%  2%  2%&#xA;[libx264 @ 00000291af0ef180] i8c dc,h,v,p: 100%  0%  0%  0%&#xA;[libx264 @ 00000291af0ef180] Weighted P-Frames: Y:0.0% UV:0.0%&#xA;[libx264 @ 00000291af0ef180] kb/s:7.65&#xA;
