How to write to fifo in while loop and read in continuous process
18 avril 2019, par Russ_ellI’m running 3 multiprocess while loops that each write to seperate fifo’s , that are read by a continuously running ffmpeg process. This runs for the first loop of each process then stops.
The code below is one of the write loops ( the other two are pretty much the same ), and the read process.
def dubv():
while True:
print('loop')
file, dur = getFile('vocal')
fx = (
AudioEffectsChain()
.delay()
)
songvfx = fx(file)
with open('/tmp/pipe2.fifo', 'wb') as p1:
print('open s fifo')
p1.write(songvfx.T.tobytes())
p1.close()
print('close s fifo')
del songvfx
def mixer():
command4 = [
'ffmpeg',
'-nostdin',
'-re',
'-y',
'-thread_queue_size', '4096',
'-ac', '2',
'-ar', '44100',

'-map', '[map]',
'-c:a', 'libmp3lame',
'-b:a', '320k',
'-f', 'mp3',
'icecast://source:hackme@localhost:8000/test'
]
o = open('/tmp/pipe1.fifo', 'rb')
o2 = open('/tmp/pipe2.fifo', 'rb')
o3 = open('/tmp/pipe3.fifo', 'rb')
mix = sp.Popen(command4, stdin=DEVNULL, bufsize=4096)
mix.wait()I’d like the write process to write to fifo2 , then loop and continue writing to fifo2 , to be read in the mixer process continuously.
EDIT :
I think the problem is coming from the reader closing as the loop runs once , then runs round the loop , open the fifo but never prints ’close s fifo’ again , so i presume it cant write to the file ?
EDIT 2 :
I have resolved this by moving the fifo close out of the loop. My writer is now
def dubv():
with open('/tmp/pipe2.fifo', 'wb') as p2:
while True:
print('loop')
file, dur = getFile('vocal')
fx = (
AudioEffectsChain()
.delay()
)
songvfx = fx(file)
p2.write(songvfx.T.tobytes())
del songvfx
time.sleep(2)
p2.close()
print('close s fifo')and the reader doesn’t open the fifo files as ffmpeg seems to deal with this.

How to show a watermark for 3 second on a MP4 using FFmpeg
6 février 2014, par b1izzardI need to add a 3-second watermark to a Camera recorded video in Android. I'm using FFmpeg static build to execute the commands.
Approach I
I had tried the below command using latest version of FFmpeg(version N-60108-gda25a65) in my Desktop running Linux Mint, the command works fine.
ffmpeg -y -itsoffset 3 -i input.mp4 -i myImage.jpg -filter_complex "[0:v][1:v]overlay=0:0:enable=between(t\,0\,3)" -codec:a copy output.mp4
In Android I'm using the FFmpegv1.2 with below config to execute the command.
*******Starting FFMPEG
***ffmpeg version 1.2 Copyright (c) 2000-2013 the FFmpeg developers***

String[] ffmpegCommandToAddWatermark = {
mFfmpegInstallPath, "-y", "-itsoffset","3",
"-i", INPUT_VIDEO_PATH, "-i", WATERMARK_IMAGE_PATH,
"-filter_complex","[0:v][1:v]overlay=0:0:between(t\\,0\\,3)",
"-strict","-2",
"-codec:a","copy",OUTPUT_VIDEO_PATH};
try {
Process ffmpegProcess = new ProcessBuilder(ffmpegCommandToAddWatermark)
.redirectErrorStream(true).start();
String line;
BufferedReader reader = new BufferedReader(
new InputStreamReader(ffmpegProcess.getInputStream()));
Log.d(TAG, "*******Starting FFMPEG");
while ((line = reader.readLine()) != null ) {
Log.d(TAG, "***" + line + "***");
}
Log.d(null, "****ending FFMPEG****");
} catch (Exception e) {
e.printStackTrace();
}The command execution failed with following error :
***[overlay @ 0x271f770] No option name near 'between(t,0,3)'***
***[AVFilterGraph @ 0x2711530] Error initializing filter 'overlay' with args '0:0:between(t,0,3)'***
***Error configuring filters.***The same command executes successfully when
:enable=between(t\,0\,3)
is removed, but the resulting output video has the watermark throughout the timeline, but I need watermark only for the starting 3 seconds.Approach II :
I tried to convert WaterMarkImage to WaterMarkVideo
ffmpeg -y -loop 1 -r 30 -i WaterMarkImage.jpg -b:v "4096k" -vf "scale=640:480" -t 3 WaterMarkVideo.mp4
And then merge the WaterMarkVideo.mp4+CameraRecordedVideo.mp4 using the concat command :
ffmpeg -y -f concat -i inputs.txt -c copy output.mp4
The resulting output is corrupt due to BitRate,FrameRate,etc., mismatch. Any idea to solve the problem ?.
