  • Pas question de marché, de cloud etc...

    10 avril 2011

    Le vocabulaire utilisé sur ce site essaie d’éviter toute référence à la mode qui fleurit allègrement
    sur le web 2.0 et dans les entreprises qui en vivent.
    Vous êtes donc invité à bannir l’utilisation des termes "Brand", "Cloud", "Marché" etc...
    Notre motivation est avant tout de créer un outil simple, accessible à pour tout le monde, favorisant

  • Support audio et vidéo HTML5

    10 avril 2011

    MediaSPIP utilise les balises HTML5 video et audio pour la lecture de documents multimedia en profitant des dernières innovations du W3C supportées par les navigateurs modernes.
    Pour les navigateurs plus anciens, le lecteur flash Flowplayer est utilisé.
    Le lecteur HTML5 utilisé a été spécifiquement créé pour MediaSPIP : il est complètement modifiable graphiquement pour correspondre à un thème choisi.
    Ces technologies permettent de distribuer vidéo et son à la fois sur des ordinateurs conventionnels (...)

  • HTML5 audio and video support

    13 avril 2011, par

    MediaSPIP uses HTML5 video and audio tags to play multimedia files, taking advantage of the latest W3C innovations supported by modern browsers.
    The MediaSPIP player used has been created specifically for MediaSPIP and can be easily adapted to fit in with a specific theme.
    For older browsers the Flowplayer flash fallback is used.
    MediaSPIP allows for media playback on major mobile platforms with the above (...)

  • 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

    


  • What is the most efficient way to convert wav audio string to an ogg file without writing it to disk ?

    1er janvier 2023, par Saurabh Kumar Karn

    My final objective is to use TTS to get some Indic text converted into audio and pass that audio to a messaging system that accepts mp3 and ogg. Ogg is preferred.

    


    I am on Ubuntu and my flow for getting audio string is something like this.

    


      

    1. Text in Indic language is passed to an API

      2. 


    2. API returns a json with a key value called audioContent. audioString = response.json()['audio'][0]['audioContent']

      3. 


    3. The decoded string is arrived by using this decode_string = base64.b64decode(dat)

      4. 


    


    I am currently converting it to mp3 and as you can see I am writing the wave file first and then converting it into an mp3.

    


    wav_file = open("output.wav", "wb")
decode_string = base64.b64decode(audioString)
wav_file.write(decode_string)

# Convert this to mp3 file
print('mp3file')
song = AudioSegment.from_wav("output.wav")
song.export("temp.mp3", format="mp3")


    


    Is there a way to convert audioString directly to ogg file without doing the io ?

    


    I've tried torchaudio and pyffmpeg to load audioString and do the conversion but it doesn't seem to be working.

    


  • qsv : align surface width/height to 16.

    6 mars 2018, par Ruiling Song
    qsv : align surface width/height to 16.

    Per MediaSDK documentation, it requires width/height to 16 alignment.
    
Without this patch, hwupload pipeline may fail if 16 alignment is
    
not met. Although this patch also apply 16 alignment to qsv encoder/decoder,
    
it will not bring any side-effect to them as they are already aligned.
