avconv - reducing video dimensions and file size
26 mai 2018, par VerodeIs there any way how to reduce the size of video ?
In php I use this :
$result = exec("avconv -i $file1 -vcodec libx264 -acodec aac -strict experimental $file2");Unfortynately, all produced videos have the same size as originals or are more bigger.
1) First of all I want to reduce dimensions of all videos : width : 750px, height : auto. Is it possible ?
2) Is there some way how to reduce the quality a little bit ? Of course, I don’t want blurry videos but in some websites I see that a good quality 15 minutes videofile have a size something like 50 MB. My videos of 1 minute have the same size.

Not all portions of video play well after concatenation
24 septembre 2018, par srgbndNode.JS 8.11.4, fluent-ffmpeg 2.1.2
I need to concatenate random portions of the same length of different videos in one video file. The concatenation proceeds without errors. But when I play the final concatenated file I see some portions playing well with sound, others have video "frozen" but sounds playing.
What’s the problem ? I want all portions playing well in the final concatenated file.
Concatenation config :
trex@cave:/media/trex/safe1/Development/app$ head concat_config.txt
file /media/trex/safe1/Development/app/videos/test/417912400.mp4
inpoint 145

inpoint 59
outpoint 69
file /media/trex/safe1/Development/app/videos/test/417912400.mp4
inpoint 144
outpoint 154
...In total, I have 16 portions of 2 videos. Duration of a portion is 10 sec. In the future the number of video files and portions will be much bigger.

Streaming video .mp4 H.264 baseline not working on some videos [duplicate]
8 janvier 2019, par D. B.This question already has an answer here :
I use server to stream recorder videos on Android phones and play them in Android app later. However I noticed that I am not able to play all videos, I used ffmpeg to see if there is any difference in recorded videos and where the issue might be.
That is an example of loading and playing video :Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'w1.mp4':

}I cannot see any difference in the videos characteristics. Both are baseline H.264.
Both videos are playing in chrome when I access them via direct links, the problem is on android versions 6, 7, 8.
There is strange thing because when I downloaded that not loading video directly and put in the android app to raw folder and played it directly everything worked perfectly.
I checked if the problem was bandwidth, so I uploaded bigger video about 12Mbs, mp4 as well H.264 Main and then streamed it to the app and it worked like a charm. So I suspect that the issue might be with recording bigger files within my android app.
To stream video I only use MediaPlayer.That is an example of the video I uploaded and later streamed :
