Bash : sort find results using part of a filename
13 novembre 2015, par utt50I have 3 webcams set up in a building, uploading still images to a webserver. I’m using ffmpeg to encode the jpgs to mp4 video.
The directories are set up like this :
Cam1/201504
Cam1/201505
Cam2/201504
Cam2/201505
Cam3/201504
Cam3/201505I’m using the following bash loop/ffmpeg parameters to make one video per camera, per year. This works well so far (well... except that my SSD is rapidly degrading in performance - too many simultaneous read/write operations ?) :
find Cam2/2013* -name "*.jpg" -print0 | xargs -0 cat | ffmpeg -f image2pipe -framerate 30 -vcodec mjpeg -i - -vcodec libx264 -profile:v baseline -level 3.0 -movflags +faststart -crf 19 -pix_fmt yuv420p -r 30 "Cam2-2013-30fps-19crf.mp4"The individual files are named like this (confusing ffmpeg’s built-in file sequencer) :
Cam1_2015052413543201.jpg
Cam1_2015052413544601.jpg
Cam2_2015052413032601.jpg
Cam2_2015052413544901.jpgI now need to create one video for an entire year across all 3 cameras, ordered by timestamp. To accomplish this, I need to sort the find results by the segment of the filename after the underscore.
What do I pipe the find output to to accomplish this ? For example, the files above would be ordered like this :
Cam2_2015052413032601.jpg
Cam1_2015052413543201.jpg
Cam1_2015052413544601.jpg
Cam2_2015052413544901.jpgAny help is very much appreciated !

Process terminates by signal calling ffmpeg part in Android NDK project
29 août 2013, par ÁlvaroAccording to this blog post I've build my Android ffmpeg project. I've written the native code from my Java code with the static library and the jni functions.
When I run this part of code I obtain the next logcat, any idea of why my process terminates by signal ?03-14 11:16:06.488: I/DEBUG(31): *** *** *** *** *** *** *** *** *** *** *** *** *** *** ***

ffmpeg extracts only part of 1 audio stream from .ts file
6 juillet 2020, par ShakalakahHere is what

Input #0, mpegts, from 'D:\Downloads\TEST\audio.ts':
 Duration: 02:22:29.67, start: 0.000000, bitrate: 51 kb/s
 Program 1
 Stream #0:0[0x101]: Audio: aac (LC) ([15][0][0][0] / 0x000F), 48000 Hz, stereo, fltp, 83 kb/s


So the length of .ts file is 2h:22m:29.67s and looks like it contains only audio (AAC) : when i open it in Windows Media Player i can jump to any position within the 2h:22m range and hear sound playing, and there is no video on the screen. This makes me think the extracted audio will also be of 2h:22m length, but i get only a 51m:14s file.
I tried the following commands :
1)
ffmpeg -i input.ts -vn -acodec copy outputaudio.aac2)
ffmpeg -i input.ts -map 0:v -map 0:a -c copy outputaudio.aac(as far as i understood this is "extract ALL audiotracks" command)3)
ffmpeg -i input.ts -ss 00:00:00 -t 02:22:29.6 -q:a 0 -map a outputaudio.aac(to force extraction to the full length, i.e. 2h:22m)4)
ffmpeg -i input.ts -map 0:a outputaudio.aac -map 0:v outputonlyvideo.avi(i heard this is an alternative way to force extraction of full-length audio through simultaneous extraction of video. Though looks like my .ts has no video, i decided to try this command too and got an error message : Stream map '0:v' matches no streams)What am i doing wrong ? Which alternative commands can i try ?
Is it possible, that the real length of audio stream is 51m:14s only ? But why i can listen to all 2h:22m length in Windows Media Player - could 51m:14s piece be somehow looped inside .ts to create an impression of 2h:22m length ?
