How to set codec at FFMPEG android Kotlin ?
7 avril 2022, par AndrewI'm trying to set code at android compression process, but I received such error :


Unrecognized option 'vcodec libx264 \'.



my general config you can see below :


val inputs: ArrayList<string> = ArrayList()
inputs.apply {
add("-y")
add("-i")
add(file.absolutePath)
add("-s")
add("${1080}x${720}")
add("-r")
add("${25}")
add("-vcodec libx264 \\")
add("mpeg4")
add("-b:v")
add("150k")
add("-b:a")
add("48000")
add("-ac")
add("2")
add("-ar")
add("22050")
add("-preset")
add("ultrafast")
add(resFile.absolutePath)
}
</string>


The problem which I try to solve :
compressed video can't be played in no web-browser player, so as I understood I have to set some special codec which is damaged during compression. I tried to remove at all this field in config array, but I the lib looked for this field during compression.


Also saw this question and added this field to the config :


add("-movflags +faststart")



but I received this error :


Unrecognized option 'movflags +faststart'.



maybe I missed smth ?


UPDATE


Tried to add -
add("--enable-libx264")
---> Didn't help :(

Decode h264 video with csharp
28 août 2011, par john bowringI am looking for a way to decode h264 (or indeed any video format) using c#. The ultimate goal is to be able to decode the images and very strictly control the playback in real time. The project I am working on is a non-linear video art piece where the HD footage is required to loop and edit itself on the fly, playing back certain frame ranges and then jumping to the next randomly selected frame range seamlessly.
I have created an app which reads image files (jpegs) in from the disk and plays them on screen in order, I have total control over which frame is laoded and when it is displayed but at full HD res it takes slightly longer than I want to load the images from hard drive (which are about 500k each), I am thinking that using a compressed video format would be smaller and therefore faster to read and decode into a particular frame however I cannot find any readily avaiable way to do this.
Are there any libraries which can do this ? i.e. extract an arbitrary frame from a video file and serve it to my app in less time than it takes to show the frame (running at 25fps), I have looked into the vlc libraries and wrappers for ffmpeg but I don't know which would be better or if there would be another even better option. Also I dont know which codec would be the best choice as some are keyframe based making arbitrary frame extraction probably very difficult.
Any advice welcome, thanks

MP3 file become silent when time changed in Firefox with audio API
14 décembre 2022, par Simon TrichereauI have some problem but I need to give you some context :


I have a production environment with large audio mp3 files. Everything is working perfectly but files are too heavy. I used
ffmpeg
to reduce their Bitrates from 320kbit/s to 190kbit/s to free space in my disk.

My script worked well and I saved almost 50% of space, but before to put it in production I wanted to test it on pre-production and there is some problem with Firefox...


When I play the audio everything is working good, if I listen to it normally everything is working BUT, when I click on the range to change the time and navigate into the audio, it becomes silent. Nothing happens, I can stop, start again, change the time, nothing works, but the audio is still playing...


I don't have any errors in my console, nothing so the only solution is to reload the page and play again the audio without changing the time.


I tried in chrome and it works like a charm, but in Firefox no. I also tried without any extensions and still the same...


Do you have any idea what is happening ?


Thanks a lot !


--- EDIT 14/12/2022 ---


Ok, I have tried a lot of different solutions and I finally found one, it seems firefox doesn't support VBR (variable bitrate) so I've compressed my file in CBR and it seems to finally work ...
