  • Python : Matplotlib Animation FFmpeg, RuntimeError : No MovieWriters available

    10 décembre 2017, par ib-

    The problem I am getting is in code similar to this example :
    https://matplotlib.org/examples/animation/basic_example_writer.html

    The error :

    RuntimeError : No MovieWriters available occurs at Writer = animation.writers['ffmpeg'] in the example above.

    I am using mac, I have installed ffmpeg using brew, and even installed it with conda even though I am not using anaconda for this particular code.

    I am positive that it is installed - I have used it in terminal to change files but it is not working within the program.

    Thanks !

  • ffmpeg set buf_len

    2 avril 2013, par Jeetendra_Nath_Jha

    I have been taken input from the device file /dev/video49.

    using ffmpeg, following command writing from the terminal :

    ffmpeg -f video4linux2 -i /dev/video49 -target ntsc-vcd -s 1920x1080 pixfmt:yuv420p -vstats -bufsize 225k -an -f mpegts -vcodec mpeg4 udp://127.0.0.1:10000?pkt_size=1316

    but it gives an error given below :

    I don't know how to set the buf_len here...

    because in an error it says that the buf_len is need to be set.

  • How to implement a command line of ffmpeg with ffmpeg static lib ?

    19 novembre 2014, par JackPearse

    I need a simple ffmpeg conversion task to be done inside an application :

    ffmpeg -i input_file.m4v -vcodec copy -acodec copy -vbsf h264_mp4toannexb output_file.ts

    This works well using the terminal. I’ve successfully compiled ffmpeg’s static lib. Some examples work perfectly, that means the lib is working. How do I implement the behaviour of the above command line with this library ?

    I looked into ffmpeg.c. But there is so much code inside that it took me hours to get an idea on how it works. Finally I still don’t really understand the whole structure.

    I would be very happy if someone could help me understanding how to use the library to do the very same what the example command line does. (At the end I just want to transmux mp4 files to ts files without reencoding)

    Thanks in advance

    Jack
