  • how to solve ffmpeg video merging complain about parameters mismatching

    22 septembre 2019, par mohammad rostami siahgeli

    I'm trying to concatenate an intro video to a main video. Here's my command:

    ffmpeg -i C:\Temp\intro.mp4 -i C:\Temp\main.mp4 -filter_complex "[0:v:0][0:a:0][1:v:0][1:a:0]concat=n=2:v=1:a=1[outv][outa]" -map "[outv]" -map "[outa]" C:\Temp\output.mp4

    When I run this command in cmd, I get the following error:

    I'm not a video ninja. I know parameters are different, but I have no idea after hours of search on how to solve this. A lot of online video services concatenate these two videos and give me a reasonable result. They have a GUI though. I need to do it in code, so that I can automate it.

    How can I solve these errors?

    Update: This is the second error:

  • Why does ffmpeg stop recording at midnight ?

    22 septembre 2019, par peter

    I have a shellscript like this under Kubuntu 19.10,

    #!/bin/bash

while true
do
    FILE=/media/petermc/Security5/Camera2/Camera2_.mp4  
    FILE=${FILE%.*}`date +%Y-%m-%d_%H-%M-%S-%N`.${FILE#*.}
    echo $FILE

    ffmpeg -rtsp_transport tcp -t 00:15:00 -i rtsp://*user*:*password*@192.168.1.60:554/ch02/0 -c copy -map 0 $FILE
done

    It records files like this,

    Camera2_2019-09-21_23-36-57-874602376.mp4
Camera2_2019-09-21_23-51-57-876639147.mp4

    Basically recording 15 minutes at a time from the RTSP feed, then starting a new file.

    However it stops working at midnight, the last few lines from the log file are this,

    frame= 3987 fps= 13 q=-1.0 size=  117760kB time=00:05:06.51 bitrate=3147.3kbits/s speed=1.01x    
frame= 3994 fps= 13 q=-1.0 size=  118016kB time=00:05:07.07 bitrate=3148.4kbits/s speed=1.01x    
frame= 4001 fps= 13 q=-1.0 size=  118016kB time=00:05:07.59 bitrate=3143.1kbits/s speed=1.01x    
frame= 4008 fps= 13 q=-1.0 size=  118272kB time=00:05:08.11 bitrate=3144.6kbits/s speed=1.01x

    So there doesn't seem to be any error, it stops recording at 5 minutes into the last file with no error.

    Another piece of information is that I have 6 cameras, and 4 stopped recording, the ones connected to a DVR. I have a couple of IP cameras and they kept recording.

    What could be the cause of this? Plus, what else could I do to work around this or diagnose this?

    UPDATE:

    I believe the issue is because the DVR has a maintenance setup to restart once at week at midnight. If this is what happened, is there any way I can configure ffmpeg to restart if it has lost the stream?

  • Compressing videos from a smartphone

    21 septembre 2019, par fejesjoco

    I have a Nexus 6p with the stock camera. It's set to record at 1080p, 30fps. Here's a 5 second sample (11 MB).

    Videos from this phone come out at about 17 Mbps on average. I tried to compress it with ffmpeg with -c:v libx264 -crf 23 -preset veryslow, the result comes out at about 5.5 MB, which is about 9 Mbps.

    I think this bitrate is a bit too much. When I look at torrent file listings, I can see high quality videos at 3 GB in size on average, and if such a movie is 90 minutes long on average, that is about 4-5 Mbps which sounds okay.

    I'm wondering, why the big difference? I can notice that my video is noisy/grainy (which is expected from a phone), and that might reduce compressibility. I tried a few ffmpeg filters, like hqdn3d and atadenoise, but the noise mostly remained (maybe I didn't play with it enough). Then I figured, the video is also shaky (which is also expected), and that might reduce compressibility too (and even makes temporal noise filtering less effective). I tried to stabilize it with the deshake filter, but that didn't help either.

    I know I could just limit the bandwidth to whatever I like, but there must be a reason why ffmpeg thinks it needs a high bandwidth to maintain a certain quality, and a lower bandwidth would just decrease the quality.

    Why do these videos have such a high bitrate? What's the best way to compress them more while keeping or even increasing their quality?

  • pydub no ffprobe found

    21 septembre 2019, par Virgil Sisoe

    I have an app for MacOS that is compiled with py2app. The app uses the pydub module and the latter uses ffmpeg family package.

    The problem is that once I compile the app and move it to a different OS, the subprocess call from pydub fails to find any of the ffmpeg packages even though they are installed in /usr/local/bin.

    If I launch the app from terminal ./Nameapp.app/Contents/MacOs/Nameapp then it runs no problem, but if I launch it with double click then pydub complains not finding the packages and the app hangs where ffmpeg/ffprobe should do the work.

    I can see that pydub searches in the /usr/local/bin only if launched from terminal, otherwise no. If I add /usr/local/bin to PATH, pydub doesnt complain anymore that it doesnt find ffmpeg/ffprobe, but it still gives me an error for both ffmpeg and ffprobe: [Errno 2] No such file or directory:.

    If I hardcode the path pydub.AudioSegment.converter = "/usr/local/bin/ffmpeg", the app gives me only ffprobe error [Errno 2] No such file or directory:'ffprobe': 'ffprobe'.

    On some other posts i've seen pydub.AudioSegment.ffprobe = "/path/to/ffprobe" but it doesnt seem to work in my case?

    So my two questions are:

    How to hardcode the ffprobe path in pydub?
    How to solve this without hardcoding path?

  • How can I use FFMPEG in my discord bot thats on github
