  • How to encode multiple videos parallel (Debian)

    20 juillet 2012, par Wolfen

    I'd like to encode some video files either to MP4 and X264 format in Linux Debian.

    It is very important that I encode multiple files parallel.
    E.g. I want to encode two videos parallel on a Dual Code Machine and put the other videos in a queue. When a Video is finished I want the free core to encode the next video in the queue. Also even when this'd work with x264 I don't know about MP4.

    What is the best approach here ?
    x264 supports parallel encoding but I don't know whether this is parallel encoding for multiple files or parallel encodings of different version for one single video.
    Is there a way I can assign a encoding-process to core1 and another to core2 ?

    Sincerly,
    wolfen

  • How to concat videos using ffmpeg ?

    5 septembre 2021, par schissmantics

    I'm trying to concat several videos using ffmpeg on macOS BigSur. I tried :

    


    ffmpeg -i concat:"01-vid.mov|02-vid.mov|03-vid.mov|04-vid.mov" out.mov


    


    which results in only 01-vid.mov being re-encoded for some reason and saved to out.mov.

    


    and :

    


    cat '01-vid.mov' > vid.txt
cat '02-vid.mov' > vid.txt
cat '03-vid.mov' > vid.txt
cat '04-vid.mov' > vid.txt
ffmpeg -f concat -safe 0 -i vid.txt -c copy out.mp4


    


    Which results in the same outcome.

    


    and :

    


    cat 01-vid.mov 02-vid.mov 03-vid.mov 04-vid.mov > out.mov


    


    which results in out.mov having the size of the 4 combined but a duration of only the first one.

    


    and :

    


    I join the vids using quicktime but whenever I try to re-encode the resulting vid using ffmpeg, it produces a corrupt video despite the input seemingly ok.

    


  • Manifest error pops up when trying to download certain videos for discord.py music bot

    30 novembre 2020, par bork

    I'm trying to make a discord music bot. I'm using youtube-dl to retrieve the info and ffmpeg to play the audio out. My bot has no problems downloading videos and everything is working fine. But when I tried downloading certain videos, this error popped up :

    


    [dash @ 0x7fe45a801200] Manifest too large: 65055
https://manifest.googlevideo.com/api/manifest/dash/expire/1606336104/ei/CGq-X4G6Htauz7sPrZuCsA8/ip/14.192.212.39/id/64a943d43b8f53eb/source/youtube/requiressl/yes/playback_host/r5---sn-h5mpn-30ae.googlevideo.com/mh/Go/mm/31%2C29/mn/sn-h5mpn-30ae%2Csn-30a7rn7l/ms/au%2Crdu/mv/m/mvi/5/pl/24/hfr/all/as/fmp4_audio_clear%2Cwebm_audio_clear%2Cwebm2_audio_clear%2Cfmp4_sd_hd_clear%2Cwebm2_sd_hd_clear/initcwndbps/533750/vprv/1/mt/1606314038/fvip/5/keepalive/yes/beids/23927369/itag/0/sparams/expire%2Cei%2Cip%2Cid%2Csource%2Crequiressl%2Chfr%2Cas%2Cvprv%2Citag/sig/AOq0QJ8wRQIhAOn6Br0QsuXc-3unfhYdzXVXcydzVWioIQlKvv2U4i3OAiB6ApoiqFoPvE3YKYGPbRiId_bHQYO8zsawGGPMidYGAA%3D%3D/lsparams/playback_host%2Cmh%2Cmm%2Cmn%2Cms%2Cmv%2Cmvi%2Cpl%2Cinitcwndbps/lsig/AG3C_xAwRQIhANmxfRNBI4wSJo6trsKkq8GinQ-ADMxgHRmelBwM-GEAAiAafey9YRrZz1h1S6PzV3u0S6IsZUKscGrrGP9Pofv2uQ%3D%3D: Invalid data found when processing input


    


    After trying to download other videos, which have no problem at all, I found out that the videos showing these errors have an extra step that downloads MPD manifest. I would try to download videos that are way larger and it would work, but it's just these certain videos, with the duration of about 7-10 minutes, that would have these errors. I'm really lost.

    


    This is my code for playing the videos in the voice channels :

    


    voice = get(client.voice_clients, guild = ctx.guild)
with YoutubeDL(ydl_opts) as ydl:
                info = ydl.extract_info(url[playlist], download = False)

URL = info['formats'][0]['url']
voice.play(FFmpegPCMAudio(URL, **FFMPEG_OPTIONS))
