    I'm writing a script which can take screenshots from videos, and I've used ffmpeg and mplayer. But both of them outputing too much information, I want to suppress everything, how can I do it ? I'm running macOS Bigsur.

    


    Command

    


    ffmpeg -ss 00:30:00 -i hello.mp4 -vframes 1 -q:v 2 hello.jpg

  • Converting MTS to MP4 using FFmpeg results in no/missing audio

    17 mars 2021, par tenninebt

    I have a few videos coming from a Sony Nex-5N. Basically they are "compiled" in an AVCHD. The format that is inside is MTS. I'm able to convert the videos losslessly but the resulting MP4 has no audio.

    


    ffmpeg -i 20201205150626.MTS -c:v copy -c:a copy -an -f mp4 20201205150626.MP4 


    


    The result is no audio. Then I tried to select explicitly the audio track using -map 0:a:1 but it says that it does not matches no streams. Please have a look at the following extract :

    I can see an audio stream, and its index is 1. I have no clue what is happening.
