  • Error initializing filter 'amovie' when Join multiple files and add background music, watermark

    25 août 2020, par Nguyễn Trọng

    I am doing concatenation of multiple videos with adding background music and watermark at the same time (see below)

    


    [-y, -i, 012.mp4, -i, 011.mp4, -i, 010.mp4, -i, 009.mp4, -i, 008.mp4, -i, 007.mp4, -i, 006.mp4, -i, 005.mp4, -i, 004.mp4, -i, 003.mp4, -i, 002.mp4, -i, 001.mp4, -i, 000.mp4, -i, /storage/emulated/0/FXMotion/.cache/.watermark/logo_watermark.png, -filter_complex, [0:v][0:a][1:v][1:a][2:v][2:a][3:v][3:a][4:v][4:a][5:v][5:a][6:v][6:a][7:v][7:a][8:v][8:a][9:v][9:a][10:v][10:a][11:v][11:a][12:v][12:a]concat=n=13:v=1:a=1[video][audio];[13:v]scale=320:-1[watermark];[video][watermark]overlay=main_w-overlay_w-10:main_h-overlay_h-10[vw];amovie=/storage/emulated/0/Download/Afro B - Drogba (Joanna) Prod by Team Salut [Official Music Video].mp3:loop=0,asetpts=N/SR/TB,aformat=sample_fmts=fltp:sample_rates=44100:channel_layouts=stereo[bgmusic];[audio]aformat=sample_fmts=fltp:sample_rates=44100:channel_layouts=stereo,volume=0[fmaudio];[fmaudio][bgmusic]amerge=2,pan=stereo|c0code>

    


    When I run the above command, it has an error :

    


    [Parsed_amovie_3 @ 0x816c5c00] Failed to avformat_open_input '/storage/emulated/0/Download/Afro B - Drogba (Joanna) Prod by Team Salut'

    I don't know why it happened, is it a bug of amovie filter ?

    


    how to solve it ?, thank advance.

  • Compile Shotdetect on CentOS 7

    14 septembre 2015, par BitLegacy01

    I’m migrating a service from a Debian server to a CentOS 7 one.

    The service needs the Shotdetect command (github , official site).

    I could not make it work on CentOS though I followed all steps :

    1. Compile ffmpeg compilation guide

      1. Install needed packages

        # yum install gd-devel libxml2-devel libxslt-devel clang libvpx libvorbis

      2. Add pthread in the CMakeList file, in TARGET_LINK_LIBRARIES, because it throws an lpthread missing in linker error

      3. Compile Shotdetect

        # FFMPEG_DIR="/root/ffmpeg_build"  ./compile.sh cmd

  • Decoding VP8 On A Sega Dreamcast

    20 février 2011, par Multimedia Mike — Sega Dreamcast, VP8

    I got Google’s libvpx VP8 codec library to compile and run on the Sega Dreamcast with its Hitachi/Renesas SH-4 200 MHz CPU. So give Google/On2 their due credit for writing portable software. I’m not sure how best to illustrate this so please accept this still photo depicting my testbench Dreamcast console driving video to my monitor :



    Why ? Because I wanted to try my hand at porting some existing software to this console and because I tend to be most comfortable working with assorted multimedia software components. This seemed like it would be a good exercise.

    You may have observed that the video is blue. Shortest, simplest answer : Pure laziness. Short, technical answer : Path of least resistance for getting through this exercise. Longer answer follows.

    Update : I did eventually realize that the Dreamcast can work with YUV textures. Read more in my followup post.

    Process and Pitfalls
    libvpx comes with a number of little utilities including decode_to_md5.c. The first order of business was porting over enough source files to make the VP8 decoder compile along with the MD5 testbench utility.

    Again, I used the KallistiOS (KOS) console RTOS (aside : I’m still working to get modern Linux kernels compiled for the Dreamcast). I started by configuring and compiling libvpx on a regular desktop Linux system. From there, I was able to modify a number of configuration options to make the build more amenable to the embedded RTOS.

    I had to create a few shim header files that mapped various functions related to threading and synchronization to their KOS equivalents. For example, KOS has a threading library cleverly named kthreads which is mostly compatible with the more common pthread library functions. KOS apparently also predates stdint.h, so I had to contrive a file with those basic types.

    So I got everything compiled and then uploaded the binary along with a small VP8 IVF test vector. Imagine my surprise when an MD5 sum came out of the serial console. Further, visualize my utter speechlessness when I noticed that the MD5 sum matched what my desktop platform produced. It worked !

    Almost. When I tried to decode all frames in a test vector, the program would invariably crash. The problem was that the file that manages motion compensation (reconinter.c) needs to define MUST_BE_ALIGNED which compiles byte-wise block copy functions. This is necessary for CPUs like the SH-4 which can’t load unaligned data. Apparently, even ARM CPUs these days can handle unaligned memory accesses which is why this isn’t a configure-time option.

    Showing The Work
    I completed the first testbench application which ran the MD5 test on all 17 official IVF test vectors. The SH-4/Dreamcast version aces the whole suite.

    However, this is a video game console, so I had better be able to show the decoded video. The Dreamcast is strictly RGB— forget about displaying YUV data directly. I could take the performance hit to convert YUV -> RGB. Or, I could just display the intensity information (Y plane) rendered on a random color scale (I chose blue) on an RGB565 texture (the DC’s graphics hardware can also do paletted textures but those need to be rearranged/twiddled/swizzled).

    Results
    So, can the Dreamcast decode VP8 video in realtime ? Sure ! Well, I really need to qualify. In the test depicted in the picture, it seems to be realtime (though I wasn’t enforcing proper frame timings, just decoding and displaying as quickly as possible). Obviously, I wasn’t bothering to properly convert YUV -> RGB. Plus, that Big Buck Bunny test vector clip is only 176x144. Obviously, no audio decoding either.

    So, realtime playback, with a little fine print.

    On the plus side, it’s trivial to get the Dreamcast video hardware to upscale that little blue image to fullscreen.

    I was able to tally the total milliseconds’ worth of wall clock time required to decode the 17 VP8 test vectors. As you can probably work out from this list, when I try to play a 320x240 video, things start to break down.
