OpenGLES glReadPixels exc_bad_access
29 novembre 2011, par YannyI'm trying to create video from images using OpenGLES and ffmpeg, but on iPad(4.3) I have a crash on glReadPixels
-(NSData *) glToUIImage {
int numberOfComponents = NUMBER_OF_COMPONENTS; //4
int width = PICTURE_WIDTH;
int height = PICTURE_HEIGHT;
NSInteger myDataLength = width * height * numberOfComponents;
NSMutableData * buffer= [NSMutableData dataWithLength :myDataLength];
[self checkForGLError];
GLenum type = NUMBER_OF_COMPONENTS == 3 ? GL_RGB : GL_RGBA; //RGBA
glReadPixels(0, 0, width, height, type, GL_UNSIGNED_BYTE, [buffer mutableBytes]); //EXC_BAD_ACCESS here
return buffer;
}It is working on iPhone 4 (4.3) and iPod Touch, but have problems on iPhone 3G(3.0) and iPad(4.3). Can you help me with this issue ?
Also on iPhone 3G(3.0) and iPad(4.3) I have problems with Video - first 5-20 video frames have trash. Maybe issue with optimization ? Or architecture ?

RUN FFMPEG IN PYTHON
7 janvier 2023, par SMARTI have 1 video & 1 audio.


video's duration : 4s


audio's duration : 7.48 s


i wrote python function to combine these files


MY CODE :


import subprocess as sp

 def runffmpeg(cmd):
 try:
 pipe = sp.Popen(cmd, stdout=sp.PIPE, stderr=sp.STDOUT,
 universal_newlines=True)
 
 ffmpeg_output, _ = pipe.communicate()
 
 print(ffmpeg_output)
 return (ffmpeg_output)
 
 except sp.CalledProcessError as err:
 print("FFmpeg stdout output on error:\n" + err.output)
 
 def get_duration(fn):
 cmd = (
 f"ffprobe -v error -show_entries format=duration -of default=noprint_wrappers=1:nokey=1 {fn}")
 
 cmd1 = (
 f"ffprobe -v error -of flat=s_ -select_streams 1 -show_entries stream=duration -of default=noprint_wrappers=1:nokey=1 {fn}")
 try:
 pipe = sp.Popen(cmd, stdout=sp.PIPE, stderr=sp.STDOUT,
 universal_newlines=True)
 
 viddur, _ = pipe.communicate()
 
 print(viddur)
 
 pipe = sp.Popen(cmd1, stdout=sp.PIPE, stderr=sp.STDOUT,
 universal_newlines=True)
 
 auddur, _ = pipe.communicate()
 
 try:
 auddur = float(auddur.strip())
 except:
 auddur = 0
 
 print(auddur)
 
 # if (len(auddur) == 0):
 # auddur = 0
 
 return float(viddur.strip()), (auddur)
 
 except sp.CalledProcessError as err:
 print("FFmpeg stdout output on error:\n" + err.output)
 

def set_audio_to_video(vn, an, output):

 vdur, adur = get_duration(fn=vn)
 print(f" video duration is {vdur}")

 auddur, adur = get_duration(fn=an)
 print(f" audio duration is {auddur}")

 #cmd = (f" ffmpeg -i {vn} -i {an} -filter_complex \"[0:v]setpts=PTS*{auddur}/{vdur} [v];atempo={auddur}/{vdur} [a]\" -map \"[v]\" -map 1:a -shortest -y {output}")

cmd = (
 f" ffmpeg -i {vn} -i {an} -filter_complex \"[0:v]setpts=PTS*{auddur}/{vdur} [v]\" -map \"[v]\" -map 1:a -shortest -pix_fmt yuv420p -y {output}")
print(cmd)

x = runffmpeg(cmd=cmd)


to call the function :
set_audio_to_video(vn="cremovie.mp4", an="a1.wav", output="output.mp4")


i'm getting error :


Traceback (most recent call last):
 File "e:\MOVIEPY\FFMPEG-PYTHON.py", line 439, in <module>
 set_audio_to_video(vn="cremovie.mp4", an="a1.wav", output="output.mp4")
 File "e:\MOVIEPY\FFMPEG-PYTHON.py", line 424, in set_audio_to_video
 x = runffmpeg(cmd=cmd)
 File "e:\MOVIEPY\FFMPEG-PYTHON.py", line 399, in runffmpeg
 pipe = sp.Popen(cmd, stdout=sp.PIPE, stderr=sp.STDOUT,
 File "C:\Python39\lib\subprocess.py", line 947, in __init__
 self._execute_child(args, executable, preexec_fn, close_fds,
 File "C:\Python39\lib\subprocess.py", line 1416, in _execute_child
 hp, ht, pid, tid = _winapi.CreateProcess(executable, args,
 OSError: [WinError 87] The parameter is incorrect
</module>

final command generated by function will look like :


ffmpeg -i cremovie.mp4 -i a1.wav -filter_complex "[0:v]setpts=PTS*7.489116/4.0 [v]" -map "[v]" -map 1:a -shortest -pix_fmt yuv420p -y output.mp4


i want to extend the video's duration to audio's duration ( video's duration increased to from 4s to 7.48 s)


while running this ffmpeg command in command prompt (CMD) , its working , got no errors but in python , i'm getting errors.
