  • Losslessly convert from RGBA rawvideo to H.264

    11 décembre 2017, par J''

    I am creating a tool that generates frames of RGBA video and pipes it to ffmpeg to create an .mp4 video. Here is the command that I give ffmpeg :

    ffmpeg -y -f rawvideo -vcodec rawvideo -s 960x540 -pix_fmt rgba -r 60 -i - 
    
-an -c:v libx264 -pix_fmt yuv420p -b:v 995328k vigeo_demo.mp4

    However, the quality is very, very, poor. The video consists of around 2-px wide lines being drawn across the screen at various angles. The lines are very blurry and blocky. What could be the cause of this and how do I fix it ?

    Things I’ve tried :

    • -q:v 0
    • crf 1 (crf 0 gives me an error)

  • online free media hosting for live streaming

    30 novembre 2013, par Abdul Ali

    wanted to ask two things :

    1- How can we put the output of FFMPEG to a stream (online address to put the stream).

    2- Is there any free service (for testing purpose) to use FFMPEG and pass the output to it for live streaming .

    apologies if am unable to explain properly what is intended.

    to summarize, wish to convert images to video using FFMPEG (have tried the image to video conversion locally and seems to be working) and put the output to an online resource for live streaming and possibly also have VOD (so users who later logon can view at least from some point behind which they have missed).

  • How to store out put of ffmpeg in buffers or etc instead of phone storage in android ?

    28 mars 2018, par Hossein Yazdanfar

    I have and android studio project using ffmpeg.

    As I want to process the output of ffmpeg commands again ,I want to store the them in buffers , byte[] or etc instead of phone memory so the performance would be better.

    my project includes ffmpeg so libraries with jni and I do things with commands...
    I have heard about memory protocol but searches didn’t help me a lot...

    any Help please ?
