  • How to send time stamps to ffmpeg when encoding uncompressed video frames via stdin ?

    7 août 2023, par Spacy

    I'm writing a C# application, but this question applies to any programming language.
I know it is possible to pass uncompressed video frames (in yuv420p format) via stdin to ffmpeg.exe, but I recorded these frames to RAM from a webcam that has a variable frame rate. I have the exact time stamps for each frame. How do I send the time stamps to ffmpeg.exe together with the uncompressed frame data ?

    


    I would prefer if it was possible to send them within the stdin byte stream, but I could also provide them up front when invoking ffmpeg.exe (this might become a very long argument list though). I could also write them to a text file on disk if nothing else works.

    


  • ffmpeg replace audio with filter complex start and end time [closed]

    3 juin 2020, par a4n6c

    I have this code that I found on one of the posts in StackOverflow and I tested it and it works however the only slight problem I need fixing on this.

    



    ffmpeg -y -i  "C:\Users\test\Desktop\vidz\New folder (2)\target\vaastav song .mp4" -i "C:\Users\test\Desktop\vidz\New folder (2)\target\2.mp3" -filter_complex "[0:a]atrim=start=0:05,asetpts=PTS-STARTPTS[aud1];[1:a]atrim=0:09,afade=t=out:st=57:d=3,asetpts=PTS-STARTPTS[aud2];  [aud2][aud1]concat=n=2:v=0:a=1[aout]"  -map 0:v -map "[aout]" -c:v copy -c:a  libmp3lame "C:\Users\test\Desktop\vidz\New folder (2)\target\output1.mp4"


    



    were you see the end-time [1:a]atrim=0:09 works ok does what i need it to do but the start time is not working accordingly as it starts playing the mp3 on the start of the video even when i set the time too atrim=start=0:05.
