Resize the video
8 juin 2016, par Android devI have a requirement for video size before upload on the server and would like to resize the video to make sure it will not go the threshold.
So far I ended up with this command :
ffmpeg -y -i E:\test3.mp4 -s 640*480 -r 15 -aspect 3:4 -ab 12288 -vcodec mpeg4 -b 2097152 E:\debug_video.mp4The issues with this command :
- is it changes aspect ratio of the video
- it works too slow (30 seconds for 12 seconds 24mb video on Nexus 5)The best solution so far for the first issue is to check the video resolution first and only than run the ffmpeg.
Do you know how to do that with help of ffmpeg as two separate commands or as a single one ? Do you know how to make it faster ? Thank you in advance

VLC snytax to transcode & stream to stdout ?
4 octobre 2016, par Will TowerGoal : I am trying to use VLC as a local server to expand the video capabilities of an app created with
Adobe AIR,FlexandActionscript. I am usingVLCto stream tostdoutand reading that output from within my app.VLC Streaming capabilities
VLC Flash VideoStatus : I am able to launch
VLCas a background process and control it through its remote control interface (more detail). I can load, transcode and stream a local video file. The example app below is a barebones testbed demonstrating this.Issue : I am getting data in to my app but it is not rendering as video. I don’t know if it is a problem with my VLC commands or with writing to/reading from
stdout. This technique of reading fromstdoutin AIR works (withffmpegfor example).One of the various transcoding commands I have tried :
-I rc // remote control interface
-vvv // verbose debuging
--sout // transcode, stream to stdout
"#transcode{vcodec=FLV1}:std{access=file,mux=ffmpeg{mux=flv},dst=-}"This results in data coming into to my app but for some reason it is not rendering as video when using
appendByteswith theNetStreaminstance.If instead I write the data to an .flv file, a valid file is created – so the broken part seems to be writing it to
stdout. One thing I have noticed : I am not getting metadata through the stdout`method. If I play the file created with the command below, I do see metadata.Hoping someone sees where I am going wrong here.
// writing to a file
var output:File = File.desktopDirectory.resolvePath("stream.flv");
var outputPath:String = output.nativePath;
"#transcode{vcodec=FLV1}:std{access=file,mux=ffmpeg{mux=flv},dst=" + outputPath + "}");
Note : In order to get this to work in AIR, you need to define the app profile as "extendedDesktop"

Why does the frame count change when scaling with FFmpeg ?
22 octobre 2016, par ajmicekI use this to scale 1920x1080 H.264 videos :
ffmpeg -i IMG_1438.MOV -threads 2 -vf scale=-2:600 IMG_1438_scaledTo600.MOVAnd it works great ! But here is my question : most of the time, the frame rate stays exactly the same between the original file and the scaled file. For example :
$ mediainfo -F IMG_1426.MOV | grep Frame\ rate
Frame rate : 29.970
Frame rate : 29.970 FPS
Frame rate mode : VFR
Frame rate mode : Variable
Frame rate : 29.970
Frame rate : 29.970 (29970/1000) FPS
$ mediainfo -F IMG_1426_scaledTo600.MOV | grep Frame\ rate
Frame rate : 29.970
Frame rate : 29.970 FPS
Frame rate mode : CFR
Frame rate mode : Constant
Frame rate : 29.970
Frame rate : 29.970 (30000/1001) FPSBut sometimes, the frame rate increases dramatically :
$ mediainfo -F IMG_1438.MOV | grep Frame\ rate
Frame rate : 25.044
Frame rate : 25.044 FPS
Frame rate mode : VFR
Frame rate mode : Variable
Frame rate : 25.044
Frame rate : 25.044 FPS
$ mediainfo -F IMG_1438_scaledTo600.MOV | grep Frame\ rate
Frame rate : 120.000
Frame rate : 120.000 FPS
Frame rate mode : CFR
Frame rate mode : Constant
Frame rate : 120.000
Frame rate : 120.000 FPSWhat should I know about FFmpeg or libx264 or libswscale that will help me understand why this happens ? (Hoping to hear from LordNeckbeard, in particular).

Unsupported codec with id 0 for input stream 2
Unsupported codec with id 0 for input stream 3UPDATE
To clarify : my video above, the one with the high framerate (120 FPS) output after scaling, plays perfectly before and after scaling with FFmpeg (no sync issues, and 120 FPS is only about 14% larger in file size), I am simply trying to understand why this increase in framerate happens (just a little beyond Mulvya’s note that the framerate stored in the container is wrong).From a programming perspective, the initial issue I ran into was that I was using
frame=from FFmpeg’s sterr console output to determine progress, which reports erroneous results when the frame count increases dramatically on output ("I’m 372% done encoding ?!") ; I have since read another stackoverflow answer and changed my code to usetime=, which appears to be a more robust way for me to display FFmpeg progress. (Also, there is FFmpeg’s-progressoption, of course).Improving on the original command
My new command to scale, preserve a useful framerate, and optimize threads :
ffmpeg -i IMG_1438.MOV -vf scale=-2:600 -r 30 -vsync 0 IMG_1438_scaledTo600.MOVWhere
30is the "Maximum frame rate" frommediainfo.Thanks to help in the comments, I now know I do not fully understand FFmpeg’s use of three different time bases for timestamps :
tbn,tbc, andtbr.
They were explained by Robert Swain in 2009 and his explanation was also used to answer a Stackoverflow question about tbn, tbc, tbr.It sounds to me, as I’m pulling together comments from Mulvya below and Michael Rampe at another forum, that
tbris guessed ; it is frequently but not always the best value to use when changing from a variable to a constant frame rate video.Which leaves these 2 questions...
(1)
tbris incorrect when "field rate and frame rate" differ ? Does this happen a lot ?
(2) Is-r 30where30is the maximum frame rate reported bymediainfothe best way to do it for most codec/container combinations ? (Or should I only use this method when I am scaling a H.264/MPEG-4 AVC video ?)
