  • (FFMPEG Error)Real-time buffer [USB cam's name] too full or near too full

    9 juin 2020, par ZzangWoo

    I am doing project about making rtsp stream of my USB Camera.
And my project environment is 
- OS : windows server 2019
- CPU : AMD Ryzen 7 3700X
- RAM : 64GB
- GPU : NVIDIA GeForce RTX 2070 SUPER

    



    My project goal is to detect object with YOLO and show original cam video, detected video to client. So I need to change my USB Camera to RTSP Stream. But I had an error below picture.
enter image description here

    



    And this is my command line.

    



    ffmpeg -re -f dshow -i video="JOYTRON HD20" -pix_fmt yuv420p -vsync 1 -threads 0 -vcodec libx264 -r 30 -g 60 -sc_threshold 0 -b:v 640k -bufsize 768k -maxrate 800k -preset veryfast -profile:v baseline -tune film -acodec aac -b:a 128k -ac 2 -ar 48000 -f rtsp rtsp ://localhost:8888/test

    



    I saw an answer that the problem is bandwidth. So I added parameter. It didnt help.

    



    I also added the -rtbufsize parameter and -thread_queue_size parameter. But it didnt help anything.

    



    What should I do ??

    


  • h.265 encoding with ffmpeg, video not playing correctly

    11 mars 2020, par DanielRieken

    I got a h.264 video I would like to encode to h.265 using FFmpeg :

    ffmpeg.exe -i h264source.mkv -vcodec libx265 -preset slower -threads 0 -crf 24 -an h265output.mkv

    The source h.264 video is a recording of a RTMP-stream. At some point the video stops moving for 3 seconds. This is because of connection-issues of the original RTMP-stream.
    Of course the resulting h.265 video also stops moving for 3 seconds at the same point. But other than the h.264 video, the picture of the h.265 video is not frozen for only 3 seconds, it is frozen until the end of the video.

    I am using VLCplayer 3.0.8 for playback and it shows the following messages for the h.265 video :

    avcodec: Using D3D11VA (NVIDIA GeForce GT 1030, vendor 10de(NVIDIA), device 1d01, revision a1) for hardware decoding
    
avcodec error: hardware acceleration picture allocation failed
    
avcodec error: hardware acceleration picture allocation failed
    
avcodec error: hardware acceleration picture allocation failed
    
avcodec error: avcodec_send_packet critical error

    When I disable hardware acceleration in VLCplayer the playback of the h.265 video works fine.

    Next I encoded the h.264 to h.265 using HandBrake 1.3.0 and the resulting h.265 video also works fine in VLCplayer with hardware acceleration enabled.

    So my question is :
    Why is the playback of the h.264 and the h.265-handbrake-videos working fine in VLCplayer but not the h.265-ffmpeg video ?

    When I encode the h.264 to huffyuv and then to h.265 using FFmpeg, the resulting h.265-video also works fine :

    ffmpeg.exe -i h264source.mkv -vcodec huffyuv -an huffyuv.mkv
    
ffmpeg.exe -i huffyuv.mkv -vcodec libx265 -preset slower -threads 0 -crf 24 -an h265output.mkv

    I am using the windows build by Zeranoe, ffmpeg-4.2.2-win64-static.

    C:\ffmpeg>ffmpeg.exe -loglevel verbose -i h264source.mkv -vcodec libx265 -preset slower -threads 0 -crf 24 -an h265output.mkv
