13 mai 2017, par xakepp35Assume current directory contains files in .bmp format, named IMG_0000.bmp, IMG_0001.bmp, and so on. I need to make avi file from them, threating them as a frames. FFmpeg gives me an error, and i could not understand what is wrong. I’ve got following error message :

How can I know a certain file is a video file ?
31 mai 2019, par Arthur ParkI am trying to figure out if a certain user-uploaded file is a video file.
I first tried ffprobe,
# a png file
Input #0, png_pipe, from '<file>':
Duration: N/A, bitrate: N/A
Stream #0:0: Video: png, rgba(pc), 920x2094 [SAR 4724:4724 DAR 460:1047], 25 tbr, 25 tbn, 25 tbc
# a text file
Input #0, tty, from '<file>':
Duration: 00:00:00.24, bitrate: 40 kb/s
Stream #0:0: Video: ansi, pal8, 640x400, 25 fps, 25 tbr, 25 tbn, 25 tbc
# a video file
Input #0, matroska,webm, from '<file>':
Metadata:
encoder : libebml v1.3.5 + libmatroska v1.4.8
creation_time : 2017-12-12T20:18:42.000000Z
<redacted>
</redacted></file></file></file>but it’s too hard to figure out what’s what. Even image files and text files count as a video.
Should I compare the output
matroska,webm,
with every codec ffmpeg supports or is there a better way to do this ? -
.h264 file cannot convert to .mp4 file by using ffmpeg
21 janvier 2023, par Dr.Fail to fall asleepI have a car camera. Videos are HEVC codec but stored with .h264 file type.

I use ffmpeg to convert these .h264 file type to mp4 file type.

Most of videos are converted successfully, some videos failed.


some video convert successfully, some video failed


What is weird is that this "convert-failed" video clip can be normally played by using the video player provided from video seller.
convert-failed video clip be played successfully


I will upload two of these .h264 videos, one can be converted successfully, one cannot.


Could anyone let me know how to finish the convert.


see my ffmpeg command and output here
