avformat/mpegtsenc : fix incorrect PCR selection with multiple programs
2 août 2019, par Marton Balintavformat/mpegtsenc : fix incorrect PCR selection with multiple programs
The MPEG-TS muxer had a serious bug related to the use of multiple programs :
in that case, the PCR pid selection was incomplete for all services except one.
This patch solves this problem and selects a stream to become PCR for each
service, preferably the video stream.This patch also moves pcr calculation attributes to MpegTSWriteStream from
MpegTSService. PCR is a per-stream and not per-service thing, so it was
misleading to refer to it as something that is per-service.Also remove *service from MpegTSWriteStream because a stream can belong to
multiple services so it was misleading to select one for each stream.You can check the result with this example command :
./ffmpeg -loglevel verbose -y -f lavfi -i \
"testsrc=s=64x64:d=10,split=2[out0][tmp1] ;[tmp1]vflip[out1] ;sine=d=10,asetnsamples=1152[out2]" \
-flags +bitexact -fflags +bitexact -sws_flags +accurate_rnd+bitexact \
-codec:v libx264 -codec:a mp2 -pix_fmt yuv420p \
-map '0:v:0' \
-map '0:v:1' \
-map '0:a:0' \
-program st=0:st=2 -program st=1:st=2 -program st=2 -program st=0 -f mpegts out.tsYou should now see this :
[mpegts @ 0x37505c0] service 1 using PCR in pid=256
[mpegts @ 0x37505c0] service 2 using PCR in pid=257
[mpegts @ 0x37505c0] service 3 using PCR in pid=258
[mpegts @ 0x37505c0] service 4 using PCR in pid=256Fixes ticket #8039.
v2 : a video is stream is preferred if there are no programs, just like before

ffmpeg rename output if the file already exists
24 février 2018, par Xeno BossI am recording one hour long video clips from an rtsp stream through ffmpeg with a custom filename and I want it to check if the video file already exists each time it saves a clip to my hard drive and rename the new output to conserve both files.
For example if it is saving the clip
video-02222018.mp4
instead of overwriting it will rename it tovideo-02222018-01.mp4
if the file already exists orvideo-02222018-02.mp4
and so on as long as the file exists.Note : I am going to run this using
crontab
on alinux
system so it would fire this script each hour.
