Bash script : Cycle script until ffmpeg command restarts successfully
13 août 2023, par BellacodaI have a IP Camera and the recordings are saved with ffmpeg RTSP into a raspberry pi.


Sometimes, when the electricity shuts off and comes back on, the raspberry boots faster than the IP Camera and the ffmpeg command (saved on a crontab to run every reboot) fails to execute because it can't reach the IP Camera (that is still turning on).


I tried to put a sleep command before the command but that doesn't work either.


It also happened that when the IP Camera reboots, the raspberry closes the command, but when the camera comes back online, I have to manually lauch the command.


Is there a way to make a script that waits to run the ffmpeg command until the camera is fully online (I assume with the $ ? variable for command exit status), and to wait to restart the ffmpeg command when the camera reboots ?


The setup I have now is a crontab :
SHELL=/bin/bash
@reboot sleep 120s ; sudo ffmpeg ...

How to convert MPEG2-TTS to MPEG2-TS format to playback using ffplay
29 février 2024, par AsustorI know some OSS such as ffmpeg or gstreamer don't support to play-back MPEG2-TTS stream.
Then, I tried to convert 192 bytes TTS packet to 188 bytes TS packet by deleting first 4 bytes like :


def conv_tts2ts(rtp_payload):

 payload_len = len(rtp_payload)
 if payload_len % 192 != 0:
 raise

 pkt_num = int(payload_len / 192)
 ts_data = bytearray()
 for i in range(pkt_num):
 spos = 192 * i
 epos = spos + 192
 tmp = rtp_payload[spos:epos]
 ts_data.extend(tmp[4:])

 return ts_data

# after this, send ts_data with RTP header received from MPEG2-TTS streamer via UDP/IP.




However, ffplay and ffprobe don't reaction.


I expect to be able to play-back using ffplay as MPEG2-TS format.
Please tell me how to convert TTS to TS in order to deocde by ffmpeg ?

FFmpeg/MP4 - Force all existing frames to play at fixed frame rate
16 mai 2020, par MJosephI have an MP4 video file that I suspect is corrupt, in that
mediainfo
reports a variable frame rate, but I believe the frames present are meant to be played at a fixed frame rate. This discrepancy causes video stuttering. Is there any way to force an MP4 container (by editing header info, or frame timing tables) to simply play back all existing frames at a fixed frame rate (i.e. 24fps). Every tip I've read assumes you want to drop and/or add frames to achieve a new frame rate, while keeping all the old frame timings (i.e.ffmpeg -r
orffmpeg -filter
). These methods end up preserving the stutter and altering the size of the file. I would like to throw out the frame timings, but keep all frames, and just play them back at a constant rate. Is this possible ?
