multiple ffmpeg instance with zmqsend
6 février 2018, par liewjlsBy any chance anyone would able to point to the right direction, I have multiple ffmpeg instances running on the server and i need to change the configuration (for example change the volume) on the fly while the ffmpeg instance is running. I found this https://lists.ffmpeg.org/pipermail/ffmpeg-user/2016-September/033777.html which the zmqsend is the tool do the job.
But how can i point the zmqsend sending the command to a specific ffmpeg instance ?
I tried to run the zmqsend, but it got hanged.
thanks.

To concatenate more than two video using FFMPEG
21 décembre 2018, par Alok Kumar VermaI’ve been working on FFMPEG, this is indeed not an easy task since I’ve succeeded in doing some work. I’m done with concatenating two videos using ffmpeg but somehow when it comes to more than two it does not work. So I’m finding out some command to do my task.
The thing I did is to merge two videos are :
String complexCommand[] = {"-y", "-i", "/mnt/m_external_sd/Videos/VID-20161221-WA0000.mp4", "-i", "/mnt/m_external_sd/Videos/Brodha V - Aathma Raama [Music Video]_HD.mp4", "-strict", "experimental", "-filter_complex",
"[0:v]scale=1920x1080,setsar=1:1[v0];[1:v] scale=iw*min(1920/iw\\,1080/ih):ih*min(1920/iw\\,1080/ih), pad=1920:1080:(1920-iw*min(1920/iw\\,1080/ih))/2:(1080-ih*min(1920/iw\\,1080/ih))/2,setsar=1:1[v1];[v0][0:a][v1][1:a] concat=n=2:v=1:a=1",
"-ab", "48000", "-ac", "2", "-ar", "22050", "-s", "1920x1080", "-vcodec", "libx264","-crf","27","-q","4","-preset", "ultrafast", savingPath};The above is working fine for two videos. I’ve tried altering my code for three videos but it does not work.
What I’ve done in the above code is :
- Added one more input after the second one
- Changed the concat=3:v=1:a=1
But it does not merge and gave me this error in my LogCat :

After following the LordNeckbeard’s suggestion from the comment section, I’ve used his suggestion in my code but after doing that still no luck however the console’s output got changed and here is the command which I used :
String complexCommand[] = {"-y", "-i", "/mnt/m_external_sd/Videos/VID-20161221-WA0000.mp4", "-i", "/mnt/m_external_sd/Videos/Brodha V - Aathma Raama [Music Video]_HD.mp4", "-i", "/mnt/m_external_sd/DCIM/Sinha's POP/20150530_073113.mp4", "-strict", "experimental", "-filter_complex",

And the logs are :

Using ffmpeg for streaming video composition from Python : why the sound is cut only when streaming into a mp4 file ?
4 décembre 2017, par redantlabsI am using ffmpeg within Python for automatizing some video compositions. To do so, I am using the subprocess module of Python and run a ffmpeg command with a pipe input. This allows me to stream frame by frame the video composition from my array of raw images (numpy matrices) into ffmpeg. In the following example, I reduced the video composition to a simple video of a duration of 12 seconds. The produced ffmpeg command is :
ffmpeg -i stream_audio.mp3 -re -f rawvideo -vcodec rawvideo -s 1280x720 -pix_fmt rgb24 -r 25 -i - -map 0:a -map 1:v -y -strict -2 -f mp4 -pix_fmt yuv420p out.mp4The file stream_audio.mp3 is a well formed mp3 file corresponding to the audio output of the output mp4 file. However, the sound in the output file out.mp4 is cut 3 seconds before the end.
If I am trying to output any other format (for example avi), I do not observe this problem. The following command produces a well formed avi file.
ffmpeg -i ./stream_audio.mp3 -re -f rawvideo -vcodec rawvideo -s 1280x720 -pix_fmt rgb24 -r 25 -i - -map 0:a -map 1:v -y -b 4096k -f avi -pix_fmt yuv420p out.aviI tried to reproduce the bug with the most simple ffmpeg command without passing by Python, but did not succeed.The closest I have done is the following :
