Qualité du média après traitement
21 juin 2013, parLe bon réglage du logiciel qui traite les média est important pour un équilibre entre les partis ( bande passante de l’hébergeur, qualité du média pour le rédacteur et le visiteur, accessibilité pour le visiteur ). Comment régler la qualité de son média ?
Plus la qualité du média est importante, plus la bande passante sera utilisée. Le visiteur avec une connexion internet à petit débit devra attendre plus longtemps. Inversement plus, la qualité du média est pauvre et donc le média devient dégradé voire (...)

ffmpeg Progress Bar in php - fps=0.1 q=0.0 size= 0kB time=00:00:00.00 bitrate=N/A speed= 0x for every frame
5 mai 2020, par Mahmood HussainI want the progress of FFmpeg command like how much time is remaining or how much percentage is finished.



this ffmpeg Progress Bar - Encoding Percentage in PHP do the job for dealing with audio and video but failed in my case i.e creating video from images.



similar question Can ffmpeg show a progress bar ? in my case the command is follows



exec("$FFmpegPath -protocol_whitelist file,http,https,tcp,tls,crypto -f concat -safe 0 -i '$image_txt_file' -vsync vfr -pix_fmt yuv420p -vf 'pad=ceil(iw/2)*2:ceil(ih/2)*2' '$out_vid_name' 1>'output.txt' 2>&1", $output, $return_var);



and in my output file this is what I have

Problems video playing in some android devices (version 4+) but not in others
5 juin 2014, par anquegifollowing the settings for video in android developers, http://developer.android.com/guide/appendix/media-formats.html I encoded a video using ffmpeg like this :
ffmpeg -i gravityTrailer.mp4 -y -f mp4 -vcodec libx264 -profile:v baseline -acodec aac -strict -2 -profile:a aac_low -b:v 500k -ar 44100 -b:a 128k -ac 2 -r 30 -s 480x360 output_hq.mp4which corresponds on sd highquality in table 2 from android developers (link above).
Then i put this video in a server and use the class android.media.MediaPlayer to reproduce it from that URL like this
https://cloudapp.somedomain.com/bmftvideos/output_hq.mp4
The problem is that the video is played on android version 4+
you can see the video on :
LG G2,
Sony xperia Syou cannot see the video on :
Samsung galaxy S4,
BQ (spanish) aquaris 4.5And I don not know why
this is the ffmpeg output :

ffmpeg : Input link parameters do not match the corresponding output link parameters, when concatenating same size videos
4 mars 2021, par mSourireI'm trying to combine a video and an audio, using the following command :


ffmpeg -y -i 1.mkv -i 1.mka 
-max_muxing_queue_size 10000 -preset veryfast -r 30 -crf 20 -b:a 96000 -vbr on

aevalsrc=0:d=15ms[silence1];

[1][silence1]concat=n=2:v=0:a=1[audio]'
-map [video] -map [audio] -c:v libvpx -c:a libopus output.webm


But ffmpeg returns an error :


[Parsed_concat_2 @ 0x7f8004506d00] Input link in0:v0 parameters (size 640x480, SAR 1:1) do not match the corresponding output link in0:v0 parameters (320x240, SAR 1:1)

Error while processing the decoded data for stream #0:0
[libopus @ 0x7f800500c000] 1 frames left in the queue on closing
Conversion failed!


It looks like ffmpeg is unable to concatenate video and black frames, complaining, that video has a distinct resolution, but that's not true :


#> ffprobe 1.mkv

So, both the input source and the filter has the same resolution.


When I'm trying to change the color filter to "color=s=640x480", ffmpeg says an opposite thing :


[Parsed_concat_2 @ 0x7fca3ca185c0] Input link in0:v0 parameters (size 320x240, SAR 1:1) do not match the corresponding output link in0:v0 parameters (640x480, SAR 1:1)
[Parsed_concat_2 @ 0x7fca3ca185c0] Failed to configure output pad on Parsed_concat_2
Error reinitializing filters!
Failed to inject frame into filter network: Invalid argument


Help please to solve this !
