  • ffmpeg. convert jpeg to mp4 and stretch it [duplicate]

    12 novembre 2020, par rzlvmp

    I have image with size 561x704 and want to convert it in mp4 file with size 200x100.

    


    The problem is ffmpeg saving aspect ratio of image's width/height

    


    The result of ↓these↓ two commands is the same : file with size 79x100.

    


    ffmpeg -loop 1 -i in.jpg -c:v libx264 -t 15 -vf "scale=200:100" out.mp4
ffmpeg -loop 1 -i in.jpg -c:v libx264 -t 15 -vf "scale=-2:100" out.mp4


    


    Why ffmpeg don't allow to create 200x100 file ?

    


    Looks like simple rescaling have to work for me, but doesn't. Is it applicable to images only ?

    


    ffprobe shows correct info

    ],

    But MacOS file info shows 79x100 and QickTime player also playing with original aspect ratio. Looks like I need to resize image and stream are both...

    


  • FFmpeg pseudocolor filter - Option 'p' not found Error initializing filter 'pseudocolor' with args 'p=inferno'

    5 février 2023, par Greynol4

    I'm trying to process output from a uvc camera using ffmpeg. The original command that I was given that works on another linux distribution is :

    


    ffmpeg -input_format yuyv422 -video_size 256x384 -i /dev/video0 -vf 'crop=h=(ih/2):y=(ih/2)' -pix_fmt yuyv422 -f rawvideo - | ffplay -pixel_format gray16le -video_size 256x192 -f rawvideo -i - -vf 'normalize=smoothing=10, format=pix_fmts=rgb48, pseudocolor=p=inferno'

    


    (yes it works on his machine, I've seen the screen capture)

    


    I can get everything but the pseudocolor filter to work and this command works fine if i just delete , pseudocolor=p=inferno

    


    This is for processing the stream from a thermal camera that outputs raw data as video which necessitates the cropping and processing and is also why the resolution is so low.

    


    No matter what I do, it throws - Option 'p' not found Error initializing filter 'pseudocolor' with args 'p=inferno' \[rawvideo @ 0x625007a0\] Packet corrupt (stream = 0, dts = 3).=0/0 
I have modified it for my needs but I still cant get the pseudocolor filter to use the presets.

    


    The full configuration and output are below. This is a raspberry pi 3B+ running bullseye that I've reinstalled multiple times without resolution of this problem.

    The examples for the presets in the documentation are lacking but that makes me think that it shouldn't be giving this much trouble and I'm overlooking something.

    


    I plan on integrating this but can't until I can proceed with this proof of concept.

    


    Thanks for any help !

    


  • GStreamer x264 on Linux (ARM)

    8 septembre 2017, par Tõnu Samuel

    Trying to get streaming work with x264 encoding.

    I am doing some black magic with stitching two images which is known to work :

    gst-launch-1.0 -e \
    
    v4l2src device=/dev/video0 ! \
    
        video/x-raw,framerate=90/1,width=640,height=480 ! m.sink_0 \
    
    v4l2src device=/dev/video1 ! \
    
        video/x-raw,framerate=90/1,width=640,height=480 ! m.sink_1 \
    
    videomixer name=m sink_1::xpos=640 ! \
    
    video/x-raw,framerate=90/1,width=1280,height=480 ! \
    
    xvimagesink

    Now I am trying to get same thing over x264 stream with help of internet :

    gst-launch-1.0 -e \
    
    v4l2src device=/dev/video0 ! \

    udpsink host=127.0.0.1 port=5000

    And seems to work because no errors appear. But I see no way to receive image.

    I have tried

    gst-launch-1.0 udpsrc port=5000 ! application/x-rtp ! rtph264depay ! h264parse ! avdec_h264 ! xvimagesink

    which does not provide anything useful. Also attempted to use VLC with SDP file :

    c=IN IP4 127.0.0.1
    
m=video 5000 RTP/AVP 96
    
a=rtpmap:96 H264/3000

    I must be doing something wrong but unsure what.

    EDIT : Question about version of GStreamer. Probably this is information needed :

    ubuntu@tegra-ubuntu:~$  gst-launch-1.0 --version
    
gst-launch-1.0 version 1.2.4
