  • How do I access the files from a ffmpeg_streaming PUT request in Django ?

    8 juin 2020, par Sage

    I'm trying to stream video from my webcam using a python package called ffmpeg_streaming and Django2.0. I can see the request being received on the server side but I can't access the actual files in views.

    



    This is my views.py

    



    @csrf_exempt
def stream_video(request):
    stream = QueryDict(request.body)
    print("Stream: ", stream)
    data = {'stream': 'streaming...'}
"""
    if hasattr(request, '_post'):
        del request._post
        del request._files
    try:
        request.method = 'POST'
        request._lost_post_and_files()
        request.method = 'PUT'
    except(AttributeError):
        request.META['REQUEST_METHOD'] = 'POST'
        request._load_post_and_files()
        request.META['REQUEST_METHOD'] = 'PUT'
    request.PUT = request.POST
"""
    file_ob = request.POST
    print('Files: ', file_ob)
    files = request.FILES
    print('Files:' , files)
    return JsonResponse(data)


    



    stream_video.py

    



    import ffmpeg_streaming

video = ffmpeg_streaming.input('/dev/video0', capture=True)
_480p  = Representation(Size(854, 480), Bitrate(750 * 1024, 192 * 1024))
hls = video.hls(Formats.h264(), hls_list_size=10, hls_time=5, method='POST', post_data='File')
hls.flags('delete_segments')
hls.representations(_480p)
hls.output('http://127.0.0.1:8000/stream_video/out.m3u8')


    



    How would I go about accessing the files and treating them as uploads ?

    


  • Unable to play video recorded from OpenAi Environment

    10 mars 2021, par ipro_ultra

    I am developing some Reinforcement Learning algorithms in python and I am trying to record the environment into a video however I am unable to play the file once I have recorded it and it is only 1KB in size, I have tried an example I found online and this didn't work either so I assume it's a system issue rather than a problem with my code, I have enabled the debugging by running gym.logger.set_level(gym.logger.DEBUG) but this doesn't seem to through anything useful back, below is my code

    


    def replay_episode(self):
    self._env.reset()
    video_recorder = VideoRecorder(self._env, "{}/episode{}.mp4".format(self._output_directory, episode_number), enabled=True)
    for action_taken in self._current_episode_actions:
        self._env.render()
        video_recorder.capture_frame()
        self._env.step(action_taken)
    video_recorder.close()

for i in range(solution.get_episode_count()):
    # AI Stuff
    episode_number = i + 1
    solution.intialise_episode(episode_number)
    profiler.enable()
    while not solution.current_episode_done():
       solution.run_tick()
    solution.train_model()
    profiler.disable()
    export_profiling_results(profiler, '{}/episode{}.csv'.format(solution._output_directory, episode_number))


    # This is the bit we're intrested in
    if solution.current_episode_successful() or episode_number % 50 == 0:
        solution.replay_episode()

    done_time = time.time()
    print("Episode {} Completed in {}s".format(episode_number, done_time-start_time))
    start_time = done_time

solution.close()


    


    Here is the log I get from the environment when the replay_episode() method is called

    When I attempt to play the video I get the error : This file isn't playable. That might be because the file type is unsupported, the file extension is incorrect, or the file is corrupt. 0xc10100be

    


    Thank you in advance for any responses

    ffserver : Use AVOption API to access ffm demuxer instead of direct access depending on ABI

    server_attached is newly added so the demuxer knows if there is an attached server
    
that can update the write index. This is needed to fix a infinite loop
