  • FFMPEG - Converting MKV to MP4 on Gdrive using rclone mount. ERROR : output file #0 does not contain any stream

    30 avril 2020, par Enrique Torrez

    I am trying to convert video files from my back-up rip files library that I have on my Gdrive account. I was successfully able to set up a dedicated server + plexserver + rclone + gdrive. I have files that are big and my family are not able to stream them due to the poor internet service that I have in my country. So I am trying to reduce the file size so it can be streamed directly

    



    My rclone mount script is :

    



    rclone mount gcache: /path  --tpslimit 5 --allow-other --acd-templink-threshold 0 --stats 1s --buffer-size 64M --timeout 5s --contimeout 5s --max-read-ahead 1G --drive-chunk-size 64M -vv &


    



    And my ffmpeg script is :

    



    ffmpeg -i origen.mkv -c:v copy -movflags faststart -strict -2 convertedfile.mp4


    



    I had the following errors :

    



    moov atom not found


    



    I used this command :

    



    AtomicParsley myVideo.mp4 -P


    



    Now when I execute

    



    ffmpeg -i convertfile.mp4


    



    I get this error :

    



    Output file #0 does not contain any stream


    



    What am I doing wrong ? I need some help please.

  • ffmpeg watermarking processing is very slow

    25 février 2014, par Hitesh Rohilla

    I am working on a video processing project and using ffmpeg for watermarking. I achieve exactly what i want but the problem is that the process is very very slow.

    I am using a Intel Smart 2nd gen family Core-i5 Processor with 4GB RAM on a 32 bit operating system Microsoft Windows-8 on a 64-bit CPU.

    I tried watermarking a video [mp4] of length 1:30 Min. size of file is 1.5GB

    Whole process accomplish in 3 Hrs to watermark my video file and what i noticed while process is that ffmpeg was processing 28 frames per sec first and then later it slow down up to 20 frames per second. a normal human watch video with frame rate of 30 frame per second and process was even slower then this that's why it took more time [3 Hrs] then the actual length of video itself [1:33]

    What i think to make process efficient is to use ffmpeg Watermarking Source Code and modify it somewhat...

    I want to ask if someone have achieve fast watermarking before by any other way or have modified this code to achieve faster process in order to save my time...
