  • Le plugin : Podcasts.

    14 juillet 2010, par

    Le 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 (...)

    I send video stream from mobile app over rtmp encoded with hevc to my laptop where running script ffmpeg -f flv -listen 1 -i rtmp://192.168.0.194/s/streamKey -c:v libsvtav1 -f mpegts srt://192.168.0.167:9998?mode=caller. On the desktop i have obs with media source input srt://192.168.0.167:9998?mode=listener.

    


    When i run ffmpeg script without video codec option (-c:v libsvtav1) its working fine and in obs i can see video from my phone camera. With the option i can not see video only audio.
I clearly dont understand warning message : [mpegts @ 0x55ec921d9540] Stream 0, codec av1, is muxed as a private data stream and may not be recognized upon reading..
Do I need specify codec (av1) in obs media source or my ffmpeg script is wrong ?

    


  • ffmpeg command to convert 720p to 1080p, 1440p, 2160p compatible with YouTube [closed]

    24 juin 2024, par Tendekai Muchenje

    I have a video that I created in Final Cut Pro. When i uploaded it to Youtube, it only maxes out at 720p. I would like it to have higher options like 1080, 1440 and 2160 even if the quality does not change. Maybe 2160 is impossible, but 1440p would be nice. I have tried this command, but the resulting file is unplayable, it only plays audio.

    


    ffmpeg -i Hey\ Girl.mov -vf scale=3840x2160:flags=lanczos -c:v libx264 -crf 13 -c:a aac -b:a 512k -preset slow hey_girl_hd.mov


    


    I am looking for a command that would make at least 1080 and 1440 work on YouTube. If 2160 can work, that would be great too. If it matters, here is all the info that ffprobe throws out about the file

    Originally, I was trying to add a subtitle to in.mkv, but I keep encountering this error. When I add the subtitle to another MKV file, it works fine, so I believe the problem lies with in.mkv.

    


    Troubleshooting

    


    Output only video stream produce the same error :

    


    ffmpeg -i in.mkv -map 0:v:0 -c copy out.mkv


    


    Output only audio stream works fine :

    


    ffmpeg -i in.mkv -map 0:a:0 -c copy out.mkv


    


    Output as mp4 got no error, but the output file is unplayable :

    


    ffmpeg -i in.mkv -c copy -strict -2 out.mp4


    


    Re-encoding works fine :

    


    ffmpeg -i in.mkv -c:v libx265 -c:a copy out.mkv


    


    How can I fix the video stream in in.mkv so that I can add a subtitle stream and remux the file without re-encoding the video ? Any insights or suggestions on handling this error would be greatly appreciated.
