  • Why does ffmpeg show a corrupted video when receiving stream in MPEG TS format ?

    20 décembre 2019, par Carlo

    I’m trying to stream a CCTV footage using RTP/MPEGTS. I can properly view it in vlc using the following command(I’m using windows 10) :

    vlc --demux ts rtp://239.194.115.71:5000

    vlc

    The problem arises when I tried to receive and play it in ffmpeg using the following command :

    ffplay -f mpegts rtp://239.194.115.71:5000

    I’m getting a semi decent video for the first 5 seconds :

    first5

    After 5 seconds the video gets droopy and corrupted
    (note that the top part of the video seems to be unaffected)

    after5

    What could be problem with ffmpeg playing the stream, could it be the codec used ?

  • Keep trying a command until it returns "True" and then execute another

    6 janvier 2023, par Tyrone Hirt

    I'm trying to make a script to check the processor usage for a specific process every 10 seconds, and when the usage is less than 2% I want another 2 commands to be executed.

    


    The purpose is to know when the program has finished processing the requests, in order to release the execution of the other commands.

    


    I created this script to check the processor usage by this application :

    


    SET ProcessorUsage = wmic path Win32_PerfFormattedData_PerfProc_Process get Name,PercentProcessorTime | findstr /i /c:RenderQuery

%ProcessorUsage%


    


    And these are the commands I want to be executed when the processor usage of the RenderQuery application is less than 2% :

    


    for /f "delims=" %%X in ('dir /s/b/ad Proxy') do for /f "delims=" %%Y in ('dir /s/b/a-d "%%X"') do move "%%Y" ".\03. Proxy"

for /f "delims=" %%i in ('dir /s/b/ad Proxy') do rd "%%i"


    


    I tried to create a script that way here :

    


    SET ProcessorUsage = wmic path Win32_PerfFormattedData_PerfProc_Process get Name,PercentProcessorTime | findstr /i /c:RenderQuery
:Loop
IF %ProcessorUsage% LSS 2 (
(for /f "delims=" %%X in ('dir /s/b/ad Proxy') do for /f "delims=" %%Y in ('dir /s/b/a-d "%%X"') do move "%%Y" ".\03. Proxy") && (for /f "delims=" %%i in ('dir /s/b/ad Proxy') do rd "%%i")
) ELSE (
sleep 10 && goto Loop
)


    


    I also tried this way here :

    


    SET ProcessorUsage = wmic path Win32_PerfFormattedData_PerfProc_Process get Name,PercentProcessorTime | findstr /i /c:RenderQuery

:Loop
for %ProcessorUsage% LSS 2 do (
(for /f "delims=" %%X in ('dir /s/b/ad Proxy') do for /f "delims=" %%Y in ('dir /s/b/a-d "%%X"') do move "%%Y" ".\03. Proxy") && (for /f "delims=" %%i in ('dir /s/b/ad Proxy') do rd "%%i") || (sleep 10 && goto Loop)
)


    


    With these scripts I tried to create the window that only blinks and closes right away...

    


    What's the best way to do this ?

    


    EDIT

    


    Explaining in more detail : I work with video production, so I constantly need to render Proxy files, which are video files with low quality to be used during my video editing and replaced at the end of editing, this makes the much smoother video editing.

    


    Having said that, I have a folder model, inside this folder model there is a folder where I always download the video files from the camera and in that folder there is always a .bat file that opens all the video files in the software that generates proxy files of the camera's video files.

    


    This .bat file has this exact code :

    


    start "" "C:\Users\User\Downloads\FFmpeg_Batch_AV_Converter_Portable_2.8.4_x64\FFBatch.exe" -f "%~dp0\"


    


    When this software opens, it automatically renders the proxy files and their output is always in a child folder of the original files folder, and the name of the folder is Proxy.

    


    The issue is that I don't want them to be in several separate Proxy folders, so I created another .bat file that is in the parent folder of all video files, this script contains exactly these lines :

    


    for /f "delims=" %%X in ('dir /s/b/ad Proxy') do for /f "delims=" %%Y in ('dir /s/b/a-d "%%X"') do move "%%Y" ".\03. Proxy"

for /f "delims=" %%i in ('dir /s/b/ad Proxy') do rd "%%i"


    


    That is, it only searches recursively for files that are inside folders named Proxy, then it moves these files to the folder 03. Proxy that is inside the parent folder.

    


    The second line looks for all proxy folders (which are now empty) and deletes them.

    


    The point is : I currently run the second script manually, as soon as the render finishes, and I would like it to run automatically.

    


    Given this, I thought of adding a line in the first script, which opens the video files in the rendering program, this line would call the second script in the background, and the second script would be analyzing the CPU usage of this application every 10 seconds, and when the usage is less than 2% (in theory there is nothing else rendering, since it has a low CPU usage) it executes the lines that move the files and remove the folders.

    


    I think there's a good change for this to work, because this software renders 4 videos at a time, and this means that there is no time between stopping rendering a video and starting another... the CPU usage is always very high until all the videos are finished, so I think this would be the best signal to release the other commands.

    


  • ffmpeg : How does one designate what parts of an overlay video stream let the underlay video stream show through ?

    21 février 2023, par Walt Howard

    Stream 0 is a rotating planet created using povray. (https://www.povray.org/)

    


    Stream 1 is just a static jpeg of stars.

    


    I'm using overlay like this :

    


    nice ffmpeg -i protoplanet.mp4 -i stars.jpg \
         -filter_complex "[0:v]scale=1024:768[scaled];[1:v][scaled]overlay=0:0" \
         -movflags faststart -pix_fmt yuv420p -r 10 planet.mp4


    


    I had it working when I used the output from povray directly. I didn't have to know why that worked, because it just did. However, after adding some post processing to the planet video, the entire video has no alpha channel (educated guess) so the background stream (Stream 1) cannot show through.

    


    The post processing I did was this (which works great) : https://www.reddit.com/r/ffmpeg/comments/im2mkp/creating_a_retro_glow_effect_with_ffmpeg/

    


    But that made the video unable to have an overlay background possibly due to it destroying the alpha channel and turning many of the blacks to dark grey.

    


    I can merge the pure POVRAY output and the background and then add the glow effect, but it adds the effect to the background stars and captions also which ruins the effect to some degree. I want to glo-ify the planet first, then stick it on a pure starfield background.

    


    In thinking this over I may have to recreate the alpha channel after adding the glow effect, using a nearest match to black and dark grey to alpha.

    


    Hmmm. It might be a codec issue as I didn't specify any -c:v in any of my commands....
