  • FFMPEG converting MP4 - No video

    31 mars 2017, par mrcatmann

    I’m trying to re-encode a MP4 video with the latest version of FFMPEG (the original video is playable in all Windows players like WMP or MPC) :

    ffmpeg -re -i /home/clip.mp4 -y -preset ultrafast -crf 35 -c:a aac -threads 2 /home/conv1.mp4

    But the output file is only audio and no video. In the console I can see many strings like

    frame=    0 fps=0.0 q=0.0 Lsize=

    So it doesn’t see the video stream. Here is the ffprobe output :

    Is there any way to fix it ? Tried converting the video to different formats, or using Handbrake - still same results, no video.

  • Why X.Org's X Server has stopped working on Google Colab ?

    20 février 2021, par Rahul

    I am Using X server for the virtual screen on Google Colab and capturing that screen with ffmpeg to record it and live stream it to twitch. (for the reinforcement learning project)

    


    


    The above process was completely working till my last use of my Colab notebook (on mid-January 2021), but now (on 19th February 2021) I am using the same notebook and the streaming code has stopped working.

    


    


    I am adding config and log file data below. (I have never seen these files before because it was working, now it's not so I don't have any idea what wrong)

    


    The config file stored at /etc/X11/xorg.conf have the following data :

    I am using this github repo to setup the video-streamer

    


    If anyone wants the colab notebook for the example then I will add it over here.

    


    For this problem I am really not sure where to file an issue for this so that's why I am writing this here.

    


  • ffmpeg - 'hevc' codec changed to 'rawvideo' after copying video codec

    11 mars 2021, par Md Yeamin

    I am trying to convert some mkv videos with hevc codec to avi format. For this I run the following command :

    


    ffmpeg -i input.mkv -vcodec copy -acodec copy out.avi


    


    For some video this command works without any issue. But in some cases video does converted, but I can not play those files in any video player. I've tried several video players including VLC, SMPlayer, Deepin Movie etc.

    


    After looking into the video codec of converted video I can see that the video codec got transformed from hevc to rawvideo. Hers is the stream information of the original and the converted video files :
