Le plugin : Podcasts.
14 juillet 2010, parLe problème du podcasting est à nouveau un problème révélateur de la normalisation des transports de données sur Internet.
Deux formats intéressants existent : Celui développé par Apple, très axé sur l’utilisation d’iTunes dont la SPEC est ici ; Le format "Media RSS Module" qui est plus "libre" notamment soutenu par Yahoo et le logiciel Miro ;
Types de fichiers supportés dans les flux
Le format d’Apple n’autorise que les formats suivants dans ses flux : .mp3 audio/mpeg .m4a audio/x-m4a .mp4 (...)

Stream H264 raw data on RTSP server
1er janvier, par AitazazI have H264 hex string data saved in a list.
The data is in correct format as it is being received, I am trying to stream it to RTSP server.


I have stream the data in realtime as it is from a dashcam.


The RTSP server is deployed but when I stream frames to it, the connection is created and then ends in an instant (does not last for a second)


The code is mentioned below which performs this streaming task.


def h264_stream_to_rtsp(data_list, rtsp_url):
 try:
 ffmpeg_command = [
 "ffmpeg", 
 "-f", "h264",
 "-i", "-",
 "-vcodec", "libx264",
 "-preset", "fast",
 "-f", "rtsp",
 "-analyzeduration", "5000000",
 "-probesize", "5000000", 
 rtsp_url # The RTSP URL to stream to
 ]
 
 ffmpeg_process = subprocess.Popen(ffmpeg_command, stdin=subprocess.PIPE)

 for index, hex_data in enumerate(data_list):
 # print(f"Processing hex data {index + 1}/{len(data_list)}...")

 if len(hex_data) % 2 != 0:
 hex_data = '0' + hex_data # Append a leading zero if length is odd

 binary_data = binascii.unhexlify(hex_data)

 ffmpeg_process.stdin.write(binary_data)

 ffmpeg_process.stdin.close()

 ffmpeg_process.wait()
 print("Stream completed.")

 except KeyboardInterrupt:
 print("Stopping live stream.")
 except Exception as e:
 print(f"Error: {e}")



Logs from the RTSP server are mentioned below :


2025/01/01 10:56:04 INF [RTSP] [conn 20.174.9.78:35474] opened
2025/01/01 10:56:04 INF [RTSP] [session 1d2bb871] created by 20.174.9.78:35474

How can I stream continuously ?

Hence ffmpeg is added to the path and recognized by the console, but not by torchaudio.
