FFMPEG fails while processing MOV files
29 septembre 2020, par TomI'm trying to convert video files to DASH format. All videos work great except MOV videos.


I'm using the following command :


/usr/local/bin/ffmpeg -y -i /path/to/mov/video.mov -c:v libx264 -c:a aac -bf 1 -keyint_min 25 -g 250 -sc_threshold 40 -use_timeline 1 -use_template 1 -init_seg_name 'video_init_$RepresentationID$.$ext$' -media_seg_name 'video_chunk_$RepresentationID$_$Number%05d$.$ext$' -seg_duration 10 -hls_playlist 0 -f dash -adaptation_sets -0:s -map 0 -s:v:0 854x480 -b:v:0 750k -strict -2 -threads 12 /output/path/video.mpd



I get the error :


- 

Could not write header for output file #0 (incorrect codec parameters ?): Invalid argument ... Error initializing output stream 0:1

I guess the problem is that the file contains two not audio/video streams :
I can not find a way to exclude or ignore or copy without processing those last two streams (#2 and #3).

ffmpeg detects a videofile path when it does not exist
17 novembre 2020, par Nejc Kejzarthis is boggling my mind. I am using ffmpeg to compress videos within the following python script :


import re
import os

kage = 'MH5'
year = '2020'
month = '11'
day = '10'

# Set output dir; create it if it doesn't exist yet
downsampled_video_dir = home_data_dir + f'piCamera/downsampled_videos/{kage}/{year}/{month}/{day}/'
Path(downsampled_video_dir).mkdir(parents=True, exist_ok=True)
 
for i, video in enumerate(videos):
 # Set ffmpeg video compression terminal command and output directory for downsampled videos
 video_name = re.findall('\d+_\d+.mp4', video)[0]
 ds_output = downsampled_video_dir + video_name
 compress_command = f"ffmpeg -i {video} -vf scale={video_res[0]}:-2 {ds_output}"
 
 # Run ffmpeg video compression
 os.system(compress_command)



videos
is a list of full video paths of the videos that I wish to compress, andds_output
is a full path of where to write the compressed video.video_res[0]
contains the desired height of the video with the following-2
automatically calculating the width so that the aspect ratio is preserved.

For some reason when running this, ffmpeg detects some of the videos in the output directory as already existing and asks if I wish to overwrite them. The videos of course aren't there yet, so when I pass
y
, ffmpeg complains that no such file exists. Here is an example output for one of the problematic videos :

ffmpeg -y -i '/home/piCamera/MH4/2020/11/10/20201110_085451.mp4' -vf scale=400:300 '/home/piCamera/downsampled_videos/MH4/2020/11/10/20201110_085451.mp4'

This happens with about 3 videos out of 53, the rest run normally. I've tried restarting the terminal, deleted the whole created
downsampled_video_dir
and run again, but no matter how many times I restart, the same videos are the problem. The only thing that appears to help is if I change the output directory name. Any ideas of why this strange error is happening ?

This is being run on Ubuntu20 with python3.7.9 in a Jupyter Notebook.


Many, many thanks for all the insights !
