  • Revision 2c93a8ed5c : Give VP9 a different sync code from VP8 The new code is 0x49, 0x83, 0x42 There

    19 mai 2013, par Jingning Han

    Changed Paths :
     Modify /vp9/decoder/vp9_decodframe.c


     Modify /vp9/encoder/vp9_bitstream.c


     Modify /vp9/vp9_dx_iface.c



    Give VP9 a different sync code from VP8

    The new code is 0x49, 0x83, 0x42

    There is nothing particularly special about this code bitstream wise.
    Its derivation is the word "sync" coded using 4x6bit alphabetic indices.

  • Trying to save an animation gives error : OSError : Error saving animation to file (cause : [Errno 22] Invalid argument)

    18 octobre 2019, par Esmee

    I am trying to save an animation, but I get the error :

    OSError : Error saving animation to file (cause : [Errno 22] Invalid argument) Stdout : b’’ StdError : b’’. It may help to re-run with logging level set to DEBUG.

    I have installed ffmpeg and also added the path to it in my code. If I add print(animation.writers.list()), it gives ’ffmpeg’ in the list as well so I’m sure my computer can find the right file.

    At the top of my code, I have :

    import matplotlib.pyplot as plt
    
plt.rcParams['animation.ffmpeg_path'] = 'C:/FFmpeg/bin/ffmpeg.exe'

    And when saving the animation, I have :

    SubplotAnimation_1 = SubplotAnimation(F_vector, eta_atm, Pkid, Tb_sky)
    
Writer = animation.FFMpegWriter(fps=20, metadata=dict(artist='Me'), extra_args=['--verbose-debug'])
    
file_string = r'C:/Users/Esmee/Documents/Animations/animation_tryout.mp4'
    
print(file_string)
    
SubplotAnimation_1.save(file_string, writer=Writer)

    I have added the r in front of the string, so there are no problems with the /a in the file_string. The folder C :/Users/Esmee/Documents/Animations/ exists for sure, so that also shouldn’t be a problem.
    I have also tried

    Writer = animation.writers['ffmpeg']
    
mywriter = Writer(fps=15, metadata=dict(artist='Me'), bitrate=1800)

    But it doesn’t work either.

    I have looked at animation save gets errror, How can I overcome this key word error and No Moviewriters available, but none of them offers a solution to my problem.

    Does anyone know what the problem could be ? Thanks in advance !

  • How to re-encode a 120fps (or higher) MP4 from my Samsung Galaxy to a 30fps (example) so it plays on Windows like it does on the Samsung

    21 septembre 2022, par remark70

    I have some high fps slow-motion videos (mp4) that I've recorded on my phone, but when I copy them to windows and play them back, they play at the normal speed (or they play really fast), unless I slow down playback but this isn't a good result.

    


    What I'd like to do is re-encode (if that's the right word) the video to a standard fps (such as 30) to get a longer video (keeping all the frames), i.e. a 10 second 120fps would end up being a 40 second video at 30fps.
