mov : Export geotag metadata fields
3 juin 2014, par Martin Storsjömov : Export geotag metadata fields
The ’ ?xyz’ form is used by android devices (and according to apple
mailing list archives, also by older iOS devices). The ’loci’ field
(defined in 3GPP 26.244) is used by recent iOS devices.Even though the loci field can contain an altitude, it was plain
0 in my sample. Just export longitude and latitude, in a string
format matching the one used by the ’ ?xyz’ metadata field.Signed-off-by : Martin Storsjö <martin@martin.st>

CreateComponent(AMFVideoEncoderVCE_AVC) failed with error 36
16 février 2021, par Mitrajeet GolsangiI am working on a matplotlib project and want to save it in a mp4 video format.
I am using the ffmpeg program for converting the animation in a video. This is the code for conversion


# The animation definition

ani = FuncAnimation(figure, my_frame_function, frames=100,
 interval=5, init_func=init, blit=True, repeat=True)


# Path for ffmpeg

plt.rcParams['animation.ffmpeg_path'] = 'C:/ffmpeg/bin/ffmpeg.exe'


# Setting up the writer

Writer = writers['ffmpeg']
writer = Writer(fps=10, metadata=dict(artist='Mitrajeet'), bitrate=None)

# Trying to Save the file
ani.save("test.png", writer=writer) # ---- Error here


After running the file I get this Error


MovieWriter stderr:
