• FFmpeg disrupting "while/if" structure in Bash/shell scripting - how to fix ?

  25 avril 2020, par charles_river_runs

  I'm trying to extract a set number of frames from a series of .mp4 videos within several folders. I'm reading in variables from a CSV file, where each row of the CSV file contains the variables for each clip, which are : "dataset", "file name", "framelabel", "clip target start time", "clip target end time", "extract rate" (in seconds per frame), and "reason for exclusion."

  



  I'm using a while/if loop structure so I can avoid trying to process the videos that are excluded from our project.

  



  The while/if loop structure seems to work well when I just print out the variable names. However, when I insert a line of ffmpeg code, the variable assignments for the next video (ie, the following line read from the CSV file) go haywire.

  



  Here is the code WITHOUT the ffmpeg line, which seems to work (all the "echo" statements are just there as debugging aids to track the variable assignments) :

  



  IFS=‘,’
while read DATASET FILENAME FRAMELABEL TARGET_START TARGET_END TOTAL_DURATION EXTRACT_RATE REASON_FOR_EXCLUSION 
do  
echo “PRE FFMPEG”
echo “dataset and filename are “ $DATASET/$FILENAME
echo “target start is “ $TARGET_START
echo “target end is “ $TARGET_END

if [ $TARGET_START != EXCLUDED ] && [ $TARGET_START != Target_start ]
then
IFS=‘:’ 
read -r -a fps_array <<< "$EXTRACT_RATE"
IFS=‘,’
let "secs = ${fps_array[0]}*3600 + ${fps_array[1]}*60 + ${fps_array[2]}"
FPS_RATE=$(echo "scale=20;1/$secs" | bc)

echo “AFTER FFMPEG”
echo “dataset and filename are “ $DATASET/$FILENAME
echo “target start is “ $TARGET_START
echo “target end is “ $TARGET_END

fi
done < Test_Key.csv`



  



  The output for the code above looks like this, which is correct (I have 2 folders, "cats" and "es123", with two videos each ; one of the es123 videos is excluded from frame extraction) :

  



  “PRE FFMPEG”
“dataset and filename are “ cats/IMG_3460
“target start is “ 0:00:02
“target end is “ 0:00:24
“AFTER FFMPEG”
“dataset and filename are “ cats/IMG_3460
“target start is “ 0:00:02
“target end is “ 0:00:24
“PRE FFMPEG”
“dataset and filename are “ cats/IMG_4137
“target start is “ 0:00:10
“target end is “ 0:00:40
“AFTER FFMPEG”
“dataset and filename are “ cats/IMG_4137
“target start is “ 0:00:10
“target end is “ 0:00:40
“PRE FFMPEG”
“dataset and filename are “ es123/IMG_4577
“target start is “ EXCLUDED
“target end is “
“PRE FFMPEG”
“dataset and filename are “ es123/IMG_4839
“target start is “ 0:00:05
“target end is “ 0:00:25
“AFTER FFMPEG”
“dataset and filename are “ es123/IMG_4839
“target start is “ 0:00:05
“target end is “ 0:00:25


  



  However, I then try to add my ffmpeg line in that does the actual frame extraction :

  



  IFS=‘,’
while read DATASET FILENAME FRAMELABEL TARGET_START TARGET_END TOTAL_DURATION EXTRACT_RATE REASON_FOR_EXCLUSION 
do  
echo “PRE FFMPEG”
echo “dataset and filename are “ $DATASET/$FILENAME
echo “target start is “ $TARGET_START
echo “target end is “ $TARGET_END

if [ $TARGET_START != EXCLUDED ] && [ $TARGET_START != Target_start ]
then
IFS=‘:’ 
read -r -a fps_array <<< "$EXTRACT_RATE"
IFS=‘,’
let "secs = ${fps_array[0]}*3600 + ${fps_array[1]}*60 + ${fps_array[2]}"
FPS_RATE=$(echo "scale=20;1/$secs" | bc)

ffmpeg -i $DATASET/$FILENAME.mp4 -ss $TARGET_START -to $TARGET_END -vf fps=$FPS_RATE ${DATASET}/${DATASET}_${FILENAME}_%03d.jpg

echo “AFTER FFMPEG”
echo “dataset and filename are “ $DATASET/$FILENAME
echo “target start is “ $TARGET_START
echo “target end is “ $TARGET_END

fi
done < Test_Key.csv


  



  The result is that frames are correctly extracted for the first movie, but then the variable names for the second movie are completely screwed up (and then, of course, the code fails because the video names are wrong). You can see this in the 'echo' statements I used to track the variable naming, which become :

  



  “PRE FFMPEG”
“dataset and filename are “ cats/IMG_3460
“target start is “ 0:00:02
“target end is “ 0:00:24
“AFTER FFMPEG”
“dataset and filename are “ cats/IMG_3460
“target start is “ 0:00:02
“target end is “ 0:00:24
“PRE FFMPEG”
“dataset and filename are “ IMG_4839/es123_2
“target start is “ 0:00:25
“target end is “ 0:00:20


  



  Does anyone know why ffmpeg is affecting the functioning of the while/if loop structure here ? (I'm pretty new to shell scripting, sorry if this is something obvious). And what I can do to fix it ?

  



  Thank you !

  



  For reference, here is everything printed when I run the code with the ffmpeg line included— there are some parse errors showing up that I don't really understand but probably explain this.

• FFmpeg warning : could not find codec parameters for stream 1 [closed]

  17 avril 2020, par Mocchi

  Hello : I have videos in the TS container that are Advanced Video Codec created by Elgato Game Capture HD60 Pro. I am trying to convert the TS videos because sometimes the Elgato MP4 output videos have audio/video sync issues. I have been trying for a few days now to get a clean remuxed video into MP4. I am using this simple batch file :

  



  ffmpeg -analyzeduration 10000M -probesize 10000000M -i "Game Video.ts" -acodec copy -vcodec copy "Game Video.mp4"
pause


  



  I always get these warnings no matter what I have tried. even if I use the -vn command to ignore the video. which makes me believe FFmpeg is seeing something or can't read something in my source video. The Source video Information via Media Info is here, there is 12 Audio streams which are all the same and I only put the first two here :

  I have not been able to figure out how to address the FFmpeg warnings and I am concerned that there is something wrong with the video that I will not find out until after I delete the source video. Any help is appreciated. here is the output from FFmpeg :

  Do I need to tell FFmpeg more information about the source file which I have seen suggested but I have been unable to implement. Again all Help is appreciated

  


• ffmpeg : concat videos and merge with one audio

  15 avril 2020, par yannis_m

  I am trying to concatenate multiple videos priorly reencoded and merge an audio file on top of it all.

  



  I have tried

  



  ffmpeg -y  -i  ../../video_editing_input_dir/part_00.mp4 -i ../../video_editing_input_dir/part_01.mp4 -i ../../video_editing_input_dir/part_02.mp4 -i ../../video_editing_input_dir/part_03.mp4 -i ../../video_editing_input_dir/part_04.mp4 -i ../../video_editing_input_dir/part_05.mp4 -i ../../video_editing_input_dir/part_06.mp4 -i ../../video_editing_input_dir/part_07.mp4 -i ../../video_editing_input_dir/part_08.mp4 -i ../../video_editing_input_dir/part_09.mp4 -i ../../video_editing_input_dir/part_10.mp4 -i ../../video_editing_input_dir/part_11.mp4 -i ../../video_editing_input_dir/new_audio.mp3 -filter_complex " [0:v:0] setsar=1/1 [v0]; [1:v:0] setsar=1/1 [v1]; [2:v:0] setsar=1/1 [v2]; [3:v:0] setsar=1/1 [v3]; [4:v:0] setsar=1/1 [v4]; [5:v:0] setsar=1/1 [v5]; [6:v:0] setsar=1/1 [v6]; [7:v:0] setsar=1/1 [v7]; [8:v:0] setsar=1/1 [v8]; [9:v:0] setsar=1/1 [v9]; [10:v:0] setsar=1/1 [v10]; [11:v:0] setsar=1/1 [v11]; [v0] [v1] [v2] [v3] [v4] [v5] [v6] [v7] [v8] [v9] [v10] [v11] [12:a:0] concat=n=13:v=1:a=1 [v] [a] " -map [v] -map [a] -c:v h264 -pix_fmt yuv420p -c:a aac ../../video_editing_input_dir/tmp_output_video.mp4


  



  ( the setsar=1/1 is mandatory otherwise the concat doesn't work)

  



  And get the following error
