Creating farms of unique websites
13 avril 2011, parMediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...) -

naming dual audio tracks with ffmpeg
22 octobre 2012, par AzevedoI'm using ffmpeg to combine 1 video + 2 audio tracks into a mp4 container.
How do I set the name of each track ? (so in the player it won't be '0' and '1')
ffmpeg -i file1.avi -i extra-audio.mp4 -c copy -map 0:0 -map 0:1 -map 1:0 final.mp4
thanks !

How to pass BytesIO image objects to ffmpeg ?
13 avril 2023, par Mr.SlowI a have a (nested) list od BytesIO objects (images) that I would like to pass to ffmpeg and make a video. I do know, the ffmpeg cannot take it straight. What should I convert it in first ? There might be a better way using 'pipe :', which I did not succeed to implement yet.
(in this example code I ignore image duration and audio, too)


def merge_videos(file_id: float, audio_list: List[BinaryIO], duration_list: List[float], images_nested_list):
 # flatten the nested list of images
 images_list = [image for images_sublist in images_nested_list for image in images_sublist]
 
 additional_parameters = {'c:a': 'aac', 'c:v': 'libx264'}

 # Create a BytesIO object to hold the output video data
 output_data = io.BytesIO()

 # create the FFmpeg command with the specified parameters and pipe the output to the BytesIO object
 command = ffmpeg.output(*images_list, '-', vf='fps=10,format=yuv420p', preset='veryfast', shortest=None, r=10, max_muxing_queue_size=4000, **additional_parameters).pipe(output_data)

 try:
 # run the FFmpeg command with error and output capture
 subprocess.check_output(['ffmpeg', '-y', '-f', 'concat', '-safe', '0', '-i', 'audio.txt', '-i', '-', '-c:v', 'copy', '-c:a', 'aac', f"{PROJECT_PATH}/data/final-{file_id}.mp4"], input=output_data.getvalue())
 log.info("Final video with file_id %s has been converted successfully", file_id)



...this code returns :


TypeError: Expected incoming stream(s) to be of one of the following types: ffmpeg.nodes.FilterableStream; got <class>
</class>


How to handle it please ? Thanks for help.

How does the dataflow look like in case of using ffmpeg and ffserver ?
6 mai 2015, par randomuser1I can capture the camera image by ffmpeg and send it to ffserver, but what happens next with the data ? Can I collect it on the other site with some other client that uses ffmpeg (e.g. some c# wrapper for it) ? If so - how exactly does the data look like and how can I present it to the final user ? Can I just display the data on display port ? Or is there some other controller for that ?
Thanks !
