Combining All MP4s in Directory with ffmpeg
13 octobre 2015, par Eric MarcinowskiI’ve been wrestling trying to get the syntax right on this batch file and I can’t for the LIFE of me figure out why some things aren’t working.
1) The variable ’i’ is not getting incremented.
and
2) Concatenation on strc doesn’t seem to want to...well, concatenate.set i=0
set "strc=concat:"
for %%f in (*.mp4) do (
set /a i+=1
set "str=intermediate%i%.ts"
set strc="%strc% %str%|"
ffmpeg -i "%%f" -c copy -bsf:v h264_mp4toannexb -f mpegts "%str%"
)
set strc="%strc:-1%"
ffmpeg -i "%strc%" -c copy -bsf:a aac_adtstoasc Output.mp4 -
Size of files was increased after splitting by Ffmpeg
29 avril 2014, par user3584205I use this code to split file to multiple parts :
@echo off
for %%i in (*.mp4) do (
ffmpeg -i "%%~i" -vcodec copy -acodec copy -ss 00:00:00 -t 00:00:05 "D:\Ebook\%%~ni_1.mp4"
ffmpeg -i "%%~i" -vcodec copy -acodec copy -ss 00:00:05 -t 00:00:10 "D:\Ebook\%%~ni_2.mp4"
ffmpeg -i "%%~i" -vcodec copy -acodec copy -ss 00:00:10 "D:\Ebook\%%~ni_3.mp4"
)
pauseIt worked but I have a problem. It is total size of parts is larger than original file.
Original : 700 MB and after splitting :
Part 1: 225
Part 1: 500
Part 2: 250Why ? And how to keep same quality and size of files after splitting ? Thank you very much !

How to use Jaffree with Spring Boot for streaming a RTSP flow
25 août 2022, par JmarchiIm trying to build a APIRest and one of the things i want to do is recirculate the rtsp video provided by some security cameras to the frontend.


I have found the Jaffree, a dependency that integrates the ffmpeg into spring, until then all is good.


The problem is when i try to send the video to the frontend (make in React) i recieve this error :




Starting process : ffmpeg


Waiting for process to finish

Input #0, mpjpeg, from __________


Duration : N/A, bitrate : N/A


Stream #0:0 : Video : mjpeg (Baseline), yuvj420p(pc, bt470bg/unknown/unknown), 1920x1080 [SAR 1:1 DAR 16:9], 25 tbr, 25 tbn


[warning] Codec AVOption b (set bitrate (in bits/s)) specified for output file #0 (tcp ://127.0.0.1:52225) has not been used for any stream. The most likely reason is either wrong type (e.g. a video option with no video streams) or that it is a private option of some encoder which was not actually used for any stream.

: Interrupting starter thread (task-1) because of exception : TCP negotiation failed




The code in the backend is this :


@GetMapping(value = "/{id}/video")
public ResponseEntity<streamingresponsebody> getVideo() {
 String url = "**********";

 return ResponseEntity.ok()
 .contentType(MediaType.APPLICATION_OCTET_STREAM)
 .body(os ->{
 FFmpeg.atPath()
 .addArgument("-re")
 .addArguments("-acodec", "pcm_s16le")
 // .addArguments("-rtsp_transport", "tcp")
 .addArguments("-i", url)
 .addArguments("-vcodec", "copy")
 .addArguments("-af", "asetrate=22050")
 .addArguments("-acodec", "aac")
 .addArguments("-b:a", "96k" )
 .addOutput(PipeOutput.pumpTo(os)
 .disableStream(StreamType.AUDIO)
 .disableStream(StreamType.SUBTITLE)
 .disableStream(StreamType.DATA)
 .setFrameCount(StreamType.VIDEO, 100L)
 //1 frame every 10 seconds
 .setFrameRate(0.1)
 .setDuration(1, TimeUnit.HOURS)
 .setFormat("ismv"))
 .addArgument("-nostdin")
 .execute();
 });
 }
</streamingresponsebody>

And this is the html part :


<video width="100%" height="auto" controls="controls" autoplay="autoplay" muted="muted" src="http://localhost:7500/***/1/video">
 Sorry, your browser doesn't support embedded videos.
 </video>


What is it missing for the TCP negotiation ?
