How to execute this ffmpeg command for multiple videos in a folder and rename them on Linux terminal [duplicate]
3 février 2023, par average_grad_studentI'm trying to change the framerate of my video to 15fps and I need to do that for 100+ videos that are in the same folder


For processing a single video I use the following command-

ffmpeg -i input.mp4 -filter:v fps=fps=15 processed/input_15fpst.mp4


How do I do this for multiple videos in the folder and add a suffix _15fps to them ? I'm not very familiar with Linux programming


Thank you so much !


I tried doing this-

for f in *.MP4; do ffmpeg -i "$f" -filter:v fps=fps=15 process/"$f"; done


But I want to rename the file as well, how do I change my loop ?

avcodec/golomb : Prevent shift by negative number
10 juillet 2020, par Andreas Rheinhardtavcodec/golomb : Prevent shift by negative number
This happened in get_ue_golomb() if the cached bitstream reader was in
use, because there was no check to handle the case of the read value
not being in the supported range.
For consistency with the uncached bitstream reader and for compliance
with the documentation, every value not in the 0-8190 range is treated as
error although the cached bitstream reader could actually read values in
the range 0..65534 without problems.Reviewed-by : Michael Niedermayer <michael@niedermayer.cc>

Incorrect frame rate in video (Xuggler + MPEG 4 + H.264)
12 novembre 2014, par Vladislav BauerI have a problem with incorrect value of frame rate in output file, after converting. I made a really simple example to describe a problem :
public static void main(String[] args) {
// reader
IMediaReader reader = ToolFactory.makeReader("/tmp/1/i3.avi");
IMediaWriter writer = ToolFactory.makeWriter("/tmp/1/o3.mp4", reader);
reader.addListener(writer);
while (true) {
try {
final IError error = reader.readPacket();
if(error != null) {
System.err.println("Error decoding packet " + error.getDescription());
if (!reader.isOpen()) {
break;
}
}
} catch (final Exception ex) {
System.err.println("Error decoding packet " + ex.getMessage());
if (!reader.isOpen()) {
break;
}
}
}
}Any additional parameters for video or audio streams/codecs aren’t configured .
The input video file ("/tmp/1/i3.avi") has the following features :
- General
- Container : Audio Video Interleave (AVI)
- Video
- Dimensions : 624x352
- Codec : XVID MPEG-4
- Framerate : 24 frames per second
- Bitrate : N/A
- Audio :
- Codec : MPEG-1 Layer 3 (MP3)
- Channels : Stereo
- Sample rate : 48000 Hz
- Bitrate : 112 kbps
The output video file ("/tmp/1/o3.avi") has the following features :
- General
- Container : Quicktime
- Video
- Dimensions : 624x352
- Codec : H.264
- Framerate : 8 frames per second
- Bitrate : 378 kbps
- Audio :
- Codec : MPEG-4 AAC
- Channels : Stereo
- Sample rate : 48000 Hz
- Bitrate : 127 kbps
So, the frame rate in output file is 8 instead of 24. How can I fix it ? Please, help me..
PS : I’ve already tried Xuggler H264 FPS encoding issue and few another solutions, it doesn’t help..
UPD : After a long war with Xugler I wrote my own pure-java interface to the avconv and it works fine for me : https://github.com/vbauer/avconv4java
