Hello, What are the options for RTSPOption in the ffserver configuration file ? I am trying to stream my webcam video as a live RTSP stream. In my current configuration, all [DESCRIBE] requests fail and server returns 404 Not found. What am I doing wrong ? *Ffserver.conf:* *HTTPPort 9090* *RTSPPort 5554* *HTTPBindAddress 192.168.1.10* *RTSPBindAddress 192.168.1.10* *MaxHTTPConnections 2000* *MaxClients 1000* *MaxBandwidth 10000* ** *CustomLog /var/log/ffserver.log* *#NoDefaults* *##################################################################* *# Definition of the live feeds.

Recoding H.264/4.2.2 to H.264/4.2.0
by Mike Brown 07 Jun '17

If given an H.264/4.2.2 elementary stream, can ffmpeg recode it to H.264/4.2.0. If so, what would the command line be? Thanks.

by Wei.Yang 06 Jun '17

06 Jun '17

i'm decoding video stream using ffmpeg, what i want to do is to check if the picture is broken when a frame is decoded by avcodec_decode_video2(). i call av_frame_get_decode_error_flags() on decoded frame to get the errflags, but it returned 0 all the time. am i calling the right function to get what i want? what's the right way to check integrity of a decoded picture?

Slow motion ramp
by Jonathan Girven 05 Jun '17

05 Jun '17

I am trying to apply slow motion to a clip with a gradual ramp into and out of the slow motion period. I would like to apply this to both the video and the audio. I tried to separate my clip into multiple small sections, apply different setpts and atempo rates to each, and then concat them back together. This almost works except that after the slow motion period, the audio and video about 1s out of sync. The video and audio seem reasonable on their own. Is what I am trying to do not really possible with this method?

Recording a playing vdeo from screen is something I would only ever do as a last resort. (Are you circumventing DRM? ;-)) Have you ever had a look at youtube-dl?

A question about adding delay in a live streaming
by xyzero 02 Jun '17

02 Jun '17

Hi all: I want to add a 5s delay in a live streaming such as rtmp, and I use ffmpeg command as follows "ffmpeg -re -i rtmp://live.hkstv.hk.lxdns.com/live/hks -muxdelay 5 -c copy -f flv rtmp://localhost/rtmp/test" The result is the delay has no effect. If I change the command param "-c copy" to "-c:v h264 -c:a aac", then it works correctly in 5s delay. Delay in a live streaming must need transcoding? If transcoding is unavoidable, how to use min CPU load to add the delay? Thanks!

View segment duration for all streams
by Tyler Pacheco 02 Jun '17

02 Jun '17

I am a brand new to ffmpeg and video formats in general, so sorry if this is a really beginner question. I am trying to use ffmpeg to view the segment durations of each rendition of an HLS file from previously encoded videos, and make sure that they are valid. From my understanding this means the the "EXTINF" of each segment is less than or equal to the specified "EXT-X-TARGETDURATION" in the rendition. My main m3u8 file looks like the following: #EXTM3U > > #EXT-X-VERSION:4 > > >> #EXT-X-STREAM-INF:BANDWIDTH=62000,AVERAGE-BANDWIDTH=65000, >> CLOSED-CAPTIONS=NONE,CODECS="mp4a.40.2" > > -KIu3HfQQH-a-0.m3u8 > > #EXT-X-STREAM-INF:BANDWIDTH=288000,AVERAGE-BANDWIDTH= >> 289000,RESOLUTION=480x270,CLOSED-CAPTIONS=NONE,CODECS=" >> avc1.66.13,mp4a.40.2" > > -KIu3HfQQH-a-1.m3u8 > > #EXT-X-STREAM-INF:BANDWIDTH=380000,AVERAGE-BANDWIDTH= >> 376000,RESOLUTION=640x360,CLOSED-CAPTIONS=NONE,CODECS=" >> avc1.66.13,mp4a.40.2" > > -KIu3HfQQH-a-2.m3u8 > > #EXT-X-STREAM-INF:BANDWIDTH=1464000,AVERAGE-BANDWIDTH= >> 1249000,RESOLUTION=960x540,CLOSED-CAPTIONS=NONE,CODECS=" >> avc1.4d001e,mp4a.40.2" > > -KIu3HfQQH-a-3.m3u8 > > #EXT-X-STREAM-INF:BANDWIDTH=2093000,AVERAGE-BANDWIDTH= >> 1799000,RESOLUTION=1280x720,CLOSED-CAPTIONS=NONE,CODECS=" >> avc1.4d001e,mp4a.40.2" > > -KIu3HfQQH-a-4.m3u8 > > and each of the renditions look like: #EXTM3U > > #EXT-X-TARGETDURATION:6 > > #EXT-X-VERSION:4 > > #EXT-X-MEDIA-SEQUENCE:0 > > #EXT-X-PLAYLIST-TYPE:VOD > > #EXTINF:6, > > -KIu3HfQQH-a-1_00000.ts > > #EXTINF:6, > > -KIu3HfQQH-a-1_00001.ts > > #EXTINF:6, > > -KIu3HfQQH-a-1_00002.ts > > #EXTINF:6, > > -KIu3HfQQH-a-1_00003.ts > > ... > > I can't seem to find a way to get all segment durations for each rendition from the main file. If I know the individual .ts files, I can do `ffprobe -i "-KIu3HfQQH-a-1_00000.ts" -show_entries format=duration` on each one, but I don't know how I can get the individual files using ffprobe alone, or if there is a way I can include them all from the main file or rendition. The concat demuxer has an option for segment_time_metadata that looks promising, but I can't find any examples for it and everything I try seems to do nothing (presumably I am not using it correctly). Can anyone provide some advice? Also, is there any way I can do this with ffmpeg instead of ffprobe? Thanks, Tyler
