Could not find tag for codec h264 in stream #0 (mp4)
18 août 2019, par TabsNotSpacesI’ve been using the sickbeard_mp4_converter for a while to convert video files to mp4 by generating a script for ffmpeg. I’m not sure what I changed, but the ffmpeg script it generates no longer works and I’m having trouble debugging it. Can anyone tell from my log what the issue is ? Yes, its supposed to be an mp4 to an mp4, which is typically fine.
I’m at the point where I’m using an mp4 that worked with the same autogenerated script yesterday but it no longer is. I remember updating ffmpeg but downgrading did not resolve the issue, though I may have not downgraded enough.

Video concatenation puts sound out of sync
9 août 2019, par mmorin(Cross-posted from Video Production, where the question received no answers and may be more technical than usual video production.)
I have several
MOV
files from a DSLR camera. I concatenate them with directions from this thread :ffmpeg -safe 0 -f concat -i files_to_combine -vcodec copy -acodec copy temp.MOV
where
files_to_combine
is :file ./DSC_0013.MOV
...
file ./DSC_0019.MOVThe result has image and sound in sync for the first clip and is out of sync by fractions of a second in the second clip, and out of sync by around a second for the last clip. It is probably related to this error from the log :

rm $OUTPUT
ffmpeg -safe 0 -f concat -i $FILES -vcodec copy -acodec copy $OUTPUTWhen I trim a single file near the end, the sound and video do not seem out of sync :
ffmpeg -ss 00:09:20 -t 20 -i DSC_0014.MOV -vcodec copy -acodec copy end.MOV
When I concatenate only 30 seconds from each video, the result seems OK :
FILES=files_to_combine
OUTPUT=show2.MOV
rm $FILES
for i in 3 4 5 6 7 8 9; do
rm ${i}.MOV
duration=$(ffprobe -v 0 -show_entries format=duration -of compact=p=0:nk=1 DSC_001${i}.MOV)
start=$(echo $duration - 30 | bc)
end=$(echo $duration - 1 | bc)
ffmpeg -ss $start -t $end -i DSC_001${i}.MOV -vcodec copy -acodec copy ${i}.MOV
echo file ./${i}.MOV >> $FILES
done
rm $OUTPUT
ffmpeg -safe 0 -f concat -i $FILES -vcodec copy -acodec copy $OUTPUTThis last concatenation gives this error multiple times :
[mov @ 0x7fc3c7837400] Non-monotonous DTS in output stream 0:0; previous: 9080205, current: 9080200; changing to 9080206. This may result in incorrect timestamps in the output file.
So I am guessing that the problem is small differences in timestamps that
accumulate and become more noticeable with longer durations and the
concatenation of multiple files.For reference, the DSLR that shot these clips is a Nikon D3300 and the result
offfprobe
on one of the files is :$ ffprobe DSC_0017.MOV -hide_banner

I concatenated the files in iMovie and the sound and image are not as out of sync as with FFMPEG. Maybe iMovie aligns the timestamps at the end of each clip instead of concatenating the audio and image streams separately.
I ran the concatenation again with the latest
ffmpeg 4.1.4_1
on these files and others from the same camera. The audio and image are in sync in one case (the results lasts 46 minutes) out of sync in another (the result lasts 48 minutes). -
How can fix CalledProcessError : in ffmpeg
7 décembre 2020, par MarioI hope someone can help to troubleshoot this problem. I'm trying to save the loss plots out of Keras in the form of the following animation.






but I have been facing the following error, and ultimately I can't save the animation :



MovieWriter stderr:

I tried to ignore the error by this answer but it seems it's not the case. I also checked similar case but its answer for getting a static git binary is not my cas as well since not especial converting PNG to MP4 !



My code is as follows :



plt.rcParams['animation.ffmpeg_path'] = '/usr/bin/ffmpeg'

def animate(i, data1, data2, line1, line2):
 temp1 = data1.iloc[:int(i+1)]
 temp2 = data2.iloc[:int(i+1)]

 line1.set_data(temp1.index, temp1.value)
 line2.set_data(temp2.index, temp2.value)

 return (line1, line2)


def create_loss_animation(model_type, data1, data2):
 fig = plt.figure()
 plt.title(f'Loss on Train & Test', fontsize=25)
 plt.xlabel('Epoch', fontsize=20)
 plt.ylabel('Loss MSE for Sx-Sy & Sxy', fontsize=20)
 plt.xlim(min(data1.index.min(), data2.index.min()), max(data1.index.max(), data2.index.max()))
 plt.ylim(min(data1.value.min(), data2.value.min()), max(data1.value.max(), data2.value.max()))

 l1, = plt.plot([], [], 'o-', label='Train Loss', color='b', markevery=[-1])
 l2, = plt.plot([], [], 'o-', label='Test Loss', color='r', markevery=[-1])
 plt.legend(loc='center right', fontsize='xx-large')

 Writer = animation.writers['ffmpeg']
 writer = Writer(fps=5, bitrate=1800)

 ani = matplotlib.animation.FuncAnimation(fig, animate, fargs=(data1, data2, l1, l2), repeat=True, interval=1000, repeat_delay=1000)
 ani.save(f'{model_type}.mp4', writer=writer)
