  • convert CCTV .264 video to one of common formats (mp4, avi, etc.) via ffmpeg or other cmdline tool

    21 mars 2016, par yy502

    I’ve got a CCTV cam that produces .264 format video clips. These clips plays fine just like any other normal video recording that you would expect on portable devices, but only with it’s manufacture provided App. When played directly using VLC or mplayer, only gray blocks are visible in the picture. I doubt it is propitiatory encoding, but some kind of hardware encoded raw h264 format that I’m just lacking the right combination of arguments/options for playback or convert using ffmpeg. ffmpeg -i does report the basic metadata correctly, but also crazy amount of frame errors.... but I know the video can be played fine.

    The Android App has the following files in its lib folder :
    enter image description here

    I understand these files are not all for video decoding but also some other feature in the app. I’m just hoping someone could maybe determine what extra lib or option is needed to convert it with ffmpeg. e.g. libh264ToRGB565.so could be useful maybe...?

    This is a screenshot of what to expect from the sample video.
    enter image description here

    And here is the sample video clip (1.3M, 1280x720p) : http://146.185.145.75/vid.264
    (MD5 = 0ae871484b3832984f46e6820b21c673)

    Any suggestion is appreciated.

  • recording from webcam using ffmpeg at high framerate

    14 novembre 2017, par Zorglub29

    I have a webcam (model Brio 4K stream edition from Logitech) that is able to record at resolution 1280x720 and 60 fps in guvcview on Ubuntu 16.04. I then use a video codec ’raw camera input’. This is working fine and as expected, and the result is well a 60 fps video at the desired resolution.

    However, I need to record using command line and not GUI. The guvcview GUI crashes on my machine (segmentation fault, this has been reported by other users before), so I want to use ffmpeg instead.

    Unfortunately, when I use the command (in terminal) :

    ffmpeg -i /dev/video1 -framerate 60 -video_size 1280x720 out.mkv

    I only get around 30 fps out. This is of course not due to the camera by itself (it works at 60 fps in guvcview), but I cannot understand why I get 30 fps when I ask for 60 fps explicitely. It also looks in the output of ffmpeg as it records at 30 fps :

    Metadata:
       encoder         : Lavf56.40.101
       Stream #0:0: Video: h264 (libx264) (H264 / 0x34363248), yuv422p, 1280x720, q=-1--1, 30 fps, 1k tbn, 30 tbc

    Any suggestion how I can solve this and record at 60 fps using ffmpeg ?

    Note : I also tried something like this, with the same result (only 30 fps) :

    ffmpeg -f video4linux2 -i /dev/video1 -framerate 60.0 -video_size 1280x720 out.mkv

    Edit 1 thank you for the help in comment : order of arguments matters. Now using :

    ffmpeg -framerate 60 -video_size 1280x720 -i /dev/video1 out.mkv

    I get still around 30 fps, and a new (probably more understandable) warning message :

    [video4linux2,v4l2 @ 0x1ddc4e0] The driver changed the time per frame from 1/60 to 1/30
    Input #0, video4linux2,v4l2, from '/dev/video1':
     Duration: N/A, start: 256338.694616, bitrate: 442368 kb/s
       Stream #0:0: Video: rawvideo (YUY2 / 0x32595559), yuyv422, 1280x720, 442368 kb/s, 30 fps, 30 tbr, 1000k tbn, 1000k tbc

    I find several entries for this problem (video4linux2 + The driver changed the time per frame), but no clear solution.

    Edit 4 :

    It looks like there may still be a problem using :

    ffmpeg -f v4l2 -framerate 60 -video_size 1280x720 -input_format mjpeg -i /dev/video1 out.mkv

    As the output of ffmpeg looks like :

    Output #0, matroska, to 'out.mkv':

    frame=  198 fps= 37 q=-1.0 Lsize=    1043kB time=00:00:05.38 bitrate=1587.4kbits/s

    Is the fps indicated in the last line (37 instead of 60) reliable ? It was working at 60 fps with guvcview, so I do not think the laptop write speeed or CPU is the problem.

    Edit 5 :

    Thank you for the great help @LordNeckbeard , now it looks like everything works using your additional output argument command ffmpeg -f v4l2 -framerate 60 -video_size 1280x720 -input_format mjpeg -i /dev/video1 -preset faster -pix_fmt yuv420p out.mkv :

    $ ffmpeg -f v4l2 -framerate 60 -video_size 1280x720 -input_format mjpeg -i /dev/video1 -preset faster -pix_fmt yuv420p out.mkv
