Merge audio of multiple movies by ffmpeg command
11 février 2019, par S.TI want to merge 3 video files to one. my problem is that i can hear the audio only from 2. one of them is muted.
The command i did will show the 3 movies each one next to each other and should play the audio from the whole 3.
This is my query :
complexCommand = new String[]{"-i", tempPath1, "-i", tempPath2,"-i", tempPath3,"-filter_complex",
"[0:v]pad=width=iw+20:height=ih+20:x=10:y=10:color=green[a];" +
"[1:v]pad=width=iw+20:height=ih+20:x=10:y=10:color=red[b];" +
"[2:v]pad=width=iw+20:height=ih+20:x=10:y=10:color=blue[c];" +
"[b][c]hstack=inputs=2,scale=iw/2:-2[bottom];" +
"[a][bottom]vstack=inputs=2,scale=ih*2:-2[video];" +
"[0:a][1:a]amerge=inputs=2[audio];" + // take audio first movie, take audio second movie and merge with 2 inputs
"[audio][2:a]amerge=inputs=2[audio1]",
"-map", // map of the video
"[video]",
"-map", // map of the audio
"[audio1]",
"-ac",
"2", // number of chanels
outputFilePath};The result of this command is that i can hear only movies a and b.
Thanks a lot :)Edit
I also tried this one :
complexCommand = new String[]{"-i", tempPath1, "-i", tempPath2,"-i", tempPath3,"-filter_complex",
"[0:v]pad=width=iw+20:height=ih+20:x=10:y=10:color=green[a];" +
"[1:v]pad=width=iw+20:height=ih+20:x=10:y=10:color=red[b];" +
"[2:v]pad=width=iw+20:height=ih+20:x=10:y=10:color=blue[c];" +
"[b][c]hstack=inputs=2,scale=iw/2:-2[bottom];" +
"[a][bottom]vstack=inputs=2,scale=ih*2:-2[video];" +
"[0:a][1:a][2:a]amerge=inputs=3[audio]",
"-map", // map of the video
"[video]",
"-map", // map of the audio
"[audio]",
"-ac",
"2", // number of chanels
outputFilePath};Another Edit
After another investigation, i saw that he is not merging the last movie audio. Also if i have 4 movies, it merges 3 and you can’t hear the last one.

Overlay 2 RTSP live stream in sync
2 mai 2015, par perohuI’ve got 2 webcams. I capture the two RTSP h264 stream with FFMPEG and I’m overlaying one of the webcam’s stream on bottom right corner of the other webcam picture.
But the streams are not is sync, there is about 1 sec difference.How can I accomplish this to have both webcams in sync ?
Here is my FFMPEG command :
ffmpeg -rtsp_transport tcp -i "rtsp://xx.xx.xx.xx:555/h264/ch1/sub/av_stream" -rtsp_transport tcp -i "rtsp://xx.xx.xx.xx:554/h264/ch1/sub/av_stream" -i watermark704x400.png -filter_complex "[0]scale=496:288,crop=w=130:h=268:x=208:y=20 [pip]; [1]scale=704:400 [nagy]; [nagy][2] overlay=0:0 [nagy2];[nagy2][pip] overlay=main_w-overlay_w-5:main_h-overlay_h-5,drawtext=fontfile=/root/fonts/courbd.ttf:textfile=TEMP:fontsize=16:fontcolor=white:x=100-tw:y=7:reload=1,drawtext=fontfile=/root/fonts/courbd.ttf:textfile=HUM:fontsize=16:fontcolor=white:x=100-tw:y=40:reload=1,drawtext=fontfile=/root/fonts/courbd.ttf:text='%{localtime\:%Y.%m.%d. %T}':fontsize=16:fontcolor=white:x=60:y=h-51:shadowcolor=black:shadowx=1:shadowy=1,split=3 [a] [b] [c];[c] fps=fps=1/60 [p]" -c:v libx264 -map "[a]" -crf 23 -maxrate 1200k -bufsize 900k -f tee -movflags faststart -flags +global_header -g 100 -r 20 -rtmp_live live -profile:v main -preset:v medium -level 3.1 "/tmp/mp4/vp.feszek-`date +%Y%m%d-%H%M%S`.mp4|[f=flv]rtmp://xx.xx.xx.xx:12345/livewebcam/vp_feszek" -f image2 -y -map "[b]" -update 1 -r 1 -qscale:v 3 current.jpg -f image2 -map "[p]" -bt 20M -qscale:v 3 /tmp/jpg/`date +%Y%m%d-%H%M%S`-video%06d.jpgMaybe it is a keyframe related issue ? There are keyframes in every second in both source streams.

Blitted OpenGL Textures take less memory and CPU
16 avril 2015, par Pedro H. ForliI’m making a game using pygame + pyopengl, and right now i’m trying to make a video player on this context. To do so I use ffmpeg to load different video formats, then convert each frame to an opengl texture, as designed below, and then play the video.
class Texture(object):
def __init__(self, data, w=0, h=0):
"""
Initialize the texture from 3 diferents types of data:
filename = open the image, get its string and produce texture
surface = get its string and produce texture
string surface = gets it texture and use w and h provided
"""
if type(data) == str:
texture_data = self.load_image(data)
elif type(data) == pygame.Surface:
texture_data = pygame.image.tostring(data, "RGBA", True)
self.w, self.h = data.get_size()
elif type(data) == bytes:
self.w, self.h = w, h
texture_data = data
self.texID = 0
self.load_texture(texture_data)
def load_image(self, data):
texture_surface = pygame.image.load(data).convert_alpha()
texture_data = pygame.image.tostring(texture_surface, "RGBA", True)
self.w, self.h = texture_surface.get_size()
return texture_data
def load_texture(self, texture_data):
self.texID = glGenTextures(1)
glBindTexture(GL_TEXTURE_2D, self.texID)
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_NEAREST)
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST)
glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, self.w,
self.h, 0, GL_RGBA, GL_UNSIGNED_BYTE,
texture_data)Problem is that when i load all the textures of a given video, my RAM goes off the ceiling, about 800mb. But it’s possible to work around this by blitting each texture as it loads, like shown below.
def render():
glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT)
glLoadIdentity()
glDisable(GL_LIGHTING)
glEnable(GL_TEXTURE_2D)
glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA)
glClearColor(0, 0, 0, 1.0)
def Draw(texture, top, left, bottom, right):
"""
Draw the image on the Opengl Screen
"""
# Make sure he is looking at the position (0,0,0)
glBindTexture(GL_TEXTURE_2D, texture.texID)
glBegin(GL_QUADS)
# The top left of the image must be the indicated position
glTexCoord2f(0.0, 1.0)
glVertex2f(left, top)
glTexCoord2f(1.0, 1.0)
glVertex2f(right, top)
glTexCoord2f(1.0, 0.0)
glVertex2f(right, bottom)
glTexCoord2f(0.0, 0.0)
glVertex2f(left, bottom)
glEnd()def update(t) :
render()
Draw(t, -0.5, -0.5, 0.5, 0.5)# Check for basic Events on the pygame interface
for event in pygame.event.get():
BASIC_Game.QUIT_Event(event)
pygame.display.flip()Although this reduces the RAM consumption to an acceptable value it makes the loading time bigger than the video length.
I really don’t understand why opengl works this way, but is there a way to make a texture efficient without blitting it first ?
