Save a RTSP stream to mp4 file in android
22 décembre 2015, par aviI am working on a project where I need to read input stream from an IPCamera. I am able to fetch this in through an rtsp url.
Display the IPCamera stream. I am able to do same by using -
videoView = (VideoView) this.findViewById(R.id.videoView1);
MediaController mc = new MediaController(this);
videoView.setMediaController(mc);
videoView.setVideoURI(Uri.parse("rtsp://xxxxxxxx/camera1"));
videoView.requestFocus();Now I want to record this stream to an MP4 file. For same I am using mediarecorder.Here I am stuck.
MediaRecorder mediaRecorder = new MediaRecorder();
//mediaRecorder.setAudioSource(MediaRecorder.AudioSource.DEFAULT);
mediaRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
mediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.DEFAULT);
mediaRecorder.setOutputFile("rtsp://xxxxxxxxx/camera1");
try {
mediaRecorder.prepare();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
mediaRecorder.start();Thanks

I am confident it has nothing to do with the animation data, the error occurs even when I create a simple test animation :


import numpy as np
from matplotlib import pyplot as plt
from matplotlib import animation
# plt.rcParams['animation.ffmpeg_path'] = '/usr/bin/ffmpeg'

fig = plt.figure()
ax = plt.axes(xlim=(0, 2), ylim=(-2, 2))
line, = ax.plot([], [], lw=2)


def init():
 line.set_data([], [])
 return line,


def animate(i):
 x = np.linspace(0, 2, 1000)
 y = np.sin(2 * np.pi * (x - 0.01 * i))
 line.set_data(x, y)
 return line,


anim = animation.FuncAnimation(fig, animate, init_func=init,
 frames=200, interval=20, blit=True)

FFwriter = animation.FFMpegWriter()
anim.save('basic_animation.mp4', writer=FFwriter)



I am currently using PyCharm in LinuxMint and I have a fairly new version of FFMpeg (4.2.4) installed. Given that FFMpeg complains about 'rawvideo' which as far as I understand it is just a bunch of images in series, it seems unlikely this has anything to do with codecs. If I run ffmpeg -formats, sure enough rawvideo is in the list.


I have tried manually setting plt.rcParams, like in the commented line in the code above, with no success. I have also tried setting up both anaconda and venv environments, but I get the same error.
Annoyingly, I did not have this problem a few months ago when I was using Ubuntu. I have also verified that it works on my friends Ubuntu desktop, using the same simple venv as I set up for myself.


Any ideas ?


EDIT : I use the fish shell, if that is relevant...


Well this is peculiar. If I start a terminal from within PyCharm and check supported formats, I get the following :

As is evident, there is no support for 'rawvideo' in the list above ! Very strange indeed, I do not know which ffmpeg this list belongs to, perhaps it is a version integrated into matplotlib's animation class ?


Anyway, if I uncomment the line setting the ffmpeg_path I am back at the old error. I did get it to work however, by changing the path from '/usr/bin/ffmpeg' to '/home/j/.conda/envs/venvtest/bin/ffmpeg'. Then I get the file to run, create the animation and save it. This works for my real files as well, which do not even run that particular conda-environment. They do not recognize or find the ffmpeg I have in /usr/bin though. I have no clue why but at least I have a workaround now.


Final edit :
It is solved. It was flatpak's fault. Lesson is, don't use flatpak (or snap for that matter) to install Pycharm.
