Converting ffmpeg loudnorm first pass dcf summary report output to data.frame R
23 décembre 2022, par ChrisFollowing from operations on a video with ffmpeg, a
loudnorm
first pass report for purely audio files is produced

names(aud_proc_df)
[1] "in_files" "proc_out" "filter"

cmds_loudness_report <- with(aud_proc_df, sprintf("ffmpeg -hide_banner -i %s -af loudnorm=I=-23:TP=-2:LRA=7:print_format=summary -f null /dev/null 2>&1 | tail -n 12 >> loudness_rpt_all.txt", in_files)) # linux specific notation
lapply(cmds_loudness_report, system)



reading this as a .csv rather than .dcf


loudness_df_csv <- read.csv('loudness_rpt_all.txt', header = FALSE, sep =':')
head(loudness_df_csv)
 V1 V2
1 Input Integrated -24.7 LUFS
2 Input True Peak -1.6 dBTP
3 Input LRA 17.9 LU
4 Input Threshold -37.8 LUFS
5 Output Integrated -23.4 LUFS
6 Output True Peak -2.0 dBTP
#data
structure(list(V1 = c("Input Integrated", "Input True Peak", 
"Input LRA", "Input Threshold", "Output Integrated", "Output True Peak", 
"Output LRA", "Output Threshold", "Normalization Type", "Target Offset", 
"Input Integrated", "Input True Peak", "Input LRA", "Input Threshold", 
"Output Integrated", "Output True Peak", "Output LRA", "Output Threshold", 
"Normalization Type", "Target Offset"), V2 = c(" -24.7 LUFS", 
" -1.6 dBTP", " 17.9 LU", " -37.8 LUFS", 
" -23.4 LUFS", " -2.0 dBTP", " 14.8 LU", " -36.2 LUFS", 
" Dynamic", " +0.4 LU", " -23.9 LUFS", " +0.2 dBTP", 
" 22.0 LU", " -37.6 LUFS", " -23.6 LUFS", " -2.0 dBTP", 
" 21.9 LU", " -37.0 LUFS", " Dynamic", " +0.6 LU"
)), row.names = c(NA, 20L), class = "data.frame")



then, for column notation portability between win and linux systems


df_names <- unique(loudness_df_csv$V1)
df_names2 <- gsub(' ', '_', df_names)



and then make a data.frame


loudnorm_rpt <- data.frame(loudness_df_csv$V2[which(loudness_df_csv$V1 == df_names[1])], loudness_df_csv$V2[which(loudness_df_csv$V1 == df_names[2])], loudness_df_csv$V2[which(loudness_df_csv$V1 == df_names[3])], loudness_df_csv$V2[which(loudness_df_csv$V1 == df_names[4])], loudness_df_csv$V2[which(loudness_df_csv$V1 == df_names[5])], loudness_df_csv$V2[which(loudness_df_csv$V1 == df_names[6])], loudness_df_csv$V2[which(loudness_df_csv$V1 == df_names[7])], loudness_df_csv$V2[which(loudness_df_csv$V1 == df_names[8])], loudness_df_csv$V2[which(loudness_df_csv$V1 == df_names[9])], loudness_df_csv$V2[which(loudness_df_csv$V1 == df_names[10])])
names(loudnorm_rpt) <- df_names2
rownames(loudnorm_rpt) <- c('A', 'B')



Should I just wrap this in a function or is there a dcf to data.frame function that I've missed ?

How to show video (no audio) from ffmpeg via RTP in VLC ?
15 juillet 2019, par Sagi MannI’m trying to stream RTP (video only) from ffmpeg to VLC :
ffmpeg -stream_loop -1 -i video.mp4 -vcodec copy -an -f rtp rtp://0.0.0.0:1235
In VLC app, I do file -> "open network" and set the url to rtp ://@:1235.
But I get an error :SDP required
A description in SDP format is required to receive the RTP stream.
Note that rtp:// URIs cannot work with dynamic RTP payload format (96).What am I doing wrong ? I see in ffmpeg’s output that SDP is being generated :
SDP:
v=0
o=- 0 0 IN IP4 127.0.0.1
s=No Name
c=IN IP4 0.0.0.0
t=0 0
