Why calling libav* library doesn't have same quality as ffmpeg command line ?
10 mai 2016, par seaguestI am using the ffmpeg 3 to do the video format conversion, it works fine when I use the command line mode, but when I call the libav* library, I get a audio quality loss problem (there is a lot of noises in the audio).
Here are the two files :
mv.webm - original file
mv2.mp4 converted with libarary , a lot of noisesHere is the probe information for the mv.webm :
$ ffprobe mv.webm

Why the command line mode and use libav* library mode with same setting, but have different output ?
What should I do to call libav* library to get lossless video conversion ? -
ffmpeg concat command of many files loses quality or makes result video to stall
28 avril 2016, par edotomI have a Project that intends to have the union of several images and several videos converted to mp4 output.
Source images come from a Windows App that converted bmps to jpgs. Those images were converted to mp4 using the following command :ffmpeg -report -framerate 1/7 -i source.jpg -c:v libx264 -r 30 -pix_fmt yuv420p destination.mp4Result video can be seen without problems.
Source videos come from a vms in mkv format and are converted into mp4 using the following :
ffmpeg -i source.mkv -vcodec copy -acodec copy destination.mp4As a result I have a series for different mp4 files that are copied to a txt file which will allow us to make a concatenation into a result mp4.
The contents of txt will be something like this (jpgs should be placed alternately to videos) :
file '1_VideoMkvto.mp4'
file '2_VideoMkvto.mp4'
file '3_BmptoJpg.mp4'
file '4_VideoMkvto.mp4'
file '5_BmptoJpg.mp4'
file '7_VideoMkvto.mp4'
file '8_JpgtoMp4.mp4'
....I use the following instruction :
ffmpeg -report -f concat -i allVideos.txt -c copy results.mp4The issue that I’m experiencing is that in joined video, videos created originally from images (they were originally bmps converted to jpg) show problems like not being shown, shown for more or less time than original video or even worse... they make video player to stall when their part is played or closed without warning.
Pd. I tried to concat all videos into one single file and all jpgs-mp4 into one single file and individually they can be seen easily, but when joined together, that’s when everything starts to fail.

Using FFMPEG Android Library to convert PCM to m4a [duplicate]
11 avril 2016, par CvongrimThis question already has an answer here :
-
ffmpeg Too many bits per frame requested
2 answers
I am using https://github.com/WritingMinds/ffmpeg-android-java.
I have a PCM file that I created using AudioRecord.
I am now trying to convert the PCM file to an m4a file.
Running the following command converts it but it speeds up the audio making the voices on the recording sound like the chipmunks.
Finished command : ffmpeg -f s16be -i /storage/emulated/0/GMT/recordTestNew.pcm -strict -2 -y -c:a aac -b:a 176k /storage/emulated/0/GMT/recordTestFFMPEG.m4a
Which gives
SUCCESS with output : WARNING: linker: /data/user/0/com.globalmedicaltranscriptionapp/files/ffmpeg has text relocations. This is wasting memory and prevents security hardening. Please fix.

The frequency should be 11025, The encoding is using Android’s AudioFormat.ENCODING_PCM_16BIT, the channels are using AndioFormat.CHANNEL_IN_DEFAULT.
This is my first time working with audio so it’s been a struggle. The reason why I am using AudioRecord is because I need the audio files to be in a form that allows me to split them and potentially add new audio clips in the middle.
It seems like an issue due to the frequency not being passed to the output. I tried updating the above command to

Doing that makes the input seem to have the correct duration and bit rate but then I get the following error.
