FFmpeg - invalid argument on a creation of MP4 with .SRT - "Unable to parse option value "Link_to_the.srt" as image size...?
20 mai 2023, par sKunZelI'm stuck for 2 weeks on same problem on developping a command that bring together a .mp4 file consisting on a fixed image & audio from a .mp3 and then burnt-in subtitle from a stylized .srt into a new MP4.


Here is my command :



And you can see here the main script definitions of variables and call to fonction :




input_srt = os.path.normpath(os.path.join(input_directory, srt_file))
print(f"Chemin du fichier SRT : input_srt")
reformat_srt(input_srt)
final_video_output=os.path.normpath(os.path.join(output_directory,
os.path.splitext(mp3_file)[0] + '.mp4'))
time.sleep(0.5)
create_final_video(temp_video_output, input_srt, final_video_output)




This code generated an output file correctly named but 0 Ko. Every log i found indicated an error in the way of my .srt but when i print my input_srt it is correct.


Here i add up some logs :

I'm thinking of "E :" as the problem since on Windows it should be correct but with FFMPEG langage, i don't know...


I wish anyone can help me, and will be glad if it is a tricky solution. Else, sorry for my newbism...
Thanks

Opencv VideoCapture not streaming RTSP link and returns "no frame !"
6 septembre 2023, par Asadullah NaeemI am trying to stream my HikVision IP camera throough python. I am using
cv2.VideoCapture("rtsp_link")
which works fine on my Laptop but when I try to run the same python script with same Opencv and FFmpeg version it gives me following error :

Error :


[h264 @ 000002124c7f9a40] missing picture in access unit with size 47
[h264 @ 000002124c7f9a40] no frame!



I have so far tried to run this script on 5 computer devices but it gives the same error. I am using the following python script and my Opencv version is
4.6.0.66
and ffmpeg version2022-06-20-git-56419428a8-essentials_build-www.gyan.dev
:

Python Script :


import cv2

# RTSP stream URL
rtsp_url = "rtsp://username:password@ip_address:port/Streaming/Channels/501"

# Open the RTSP stream
cap = cv2.VideoCapture(rtsp_url)

# Check if the stream was successfully opened
if not cap.isOpened():
 print("Failed to open RTSP stream.")
 exit()

# Read and display frames from the stream
while True:
 # Read a frame from the stream
 ret, frame = cap.read()

 # Check if the frame was successfully read
 if not ret:
 print("Failed to read frame from RTSP stream.")
 break

 # Display the frame
 cv2.imshow("RTSP Stream", frame)

 # Exit if 'q' is pressed
 if cv2.waitKey(1) & 0xFF == ord('q'):
 break

# Release the resources
cap.release()
cv2.destroyAllWindows()




Update :


Code runs on a laptop on both wifi and mobile internet (4G) but on other devices rtsp link is accessible only with mobile internet (4G).

bash variable changes in loop with ffmpeg
17 septembre 2018, par MikeI wrote a skript to quickly create short preview clips from vides I recorded on timestamps that I found worth checking out later for cutting.
My file with the timestamps is written like thisFILE_NAME1#MM:SS MM:SS
FILE_NAME2#MM:SS MM:SS MM:SS MM:SSexample :
MAH01728#02:47 03:34 03:44 05:00 06:08 06:55
The script looks like this :
#!/bin/bash
while read f
do
file=$(echo $f | cut -d"#" -f1)
filename=${file}".MP4"
timestamps=$(echo $f | cut -d"#" -f2)
for time in $timestamps
do
ffmpeg -ss 00:${time}.0 -i "orig/${filename}" -c copy -t 10 "preview/${file}_${time}.MP4"
done
done < $1The script gets half of the previews that I want and on the other the filename is messed up and ffmpeg complains that the file is not found :
orig/714.MP4: No such file or directory
orig/00:58 01:25.MP4: No such file or directorySo I modified the script for trouble shooting and just put an echo in front of the ffmpeg command - now all file names are correct. What am I missing ?
ffmpeg -ss 00:01:47.0 -i orig/MAH01714.MP4 -c copy -t 10 preview/MAH01714_01:47.MP4
ffmpeg -ss 00:02:00.0 -i orig/MAH01713.MP4 -c copy -t 10 preview/MAH01713_02:00.MP4
ffmpeg -ss 00:00:58.0 -i orig/MAH01712.MP4 -c copy -t 10 preview/MAH01712_00:58.MP4
ffmpeg -ss 00:01:25.0 -i orig/MAH01712.MP4 -c copy -t 10 preview/MAH01712_01:25.MP4
