Goal is to create stream for facebook from image and audio file.
This is my command:
ffmpeg \
-re -y \
-loop 1 \
-f image2 \
-i ./maxresdefault.jpg \
-i ./audio-loop.mp3 \
-ar 44100 \
-b:a 128k \
-vcodec libx264 \
-vf scale=800:600 \
-b:v 1000k -minrate 1000k -maxrate 1000k -bufsize 500k \
-f flv 'rtmp://rtmp-api.facebook.com:80/rtmp/...'
I get error like:
Stream mapping:
Stream #0:0 -> #0:0 (mjpeg (native) -> h264 (libx264))
Stream #1:0 -> #0:1 (mp3 (native) -> mp3 (libmp3lame))

I've been searching for about 4 hours. I believe it's something to do with Sound.
I was having the same problem, ended up switching my audio encoding to libvo_aacenc instead of libmp3lame...
I have not tested if the audio still works however the stream is no longer dying.

Situation
I have accidentally overwrote .mkv file and luckily restored it by using PhotoRec.
Now I have a large size (4.9GB, about 1 hour) file named "f1.mkv" but cannot play it.
To be precise, only about the first second of the video is played, after which the screen remains still and only the current time on the timeline continues to advance.
If I try to jump ahead a few minutes, I get a dialog box that says "Output stream cannot be retrieved".
I'm using ubuntu20.04 desktop and its default media player.
What I have tried
Play it using VLC -> Same result as above
ffmpeg -i f1.mkv -> No error, showing apparently correct information as below:

Now I can see f1.mp4 for few more seconds with stuttering screen.
Is there I can do more?
I am trying to generate a periodic intra refresh h264 stream with only P frames using ffmpeg and x264 but I always get an I frame at the start.
Is there a way with x264 to create a P frame only stream?
Commands I am using:
ffmpeg -f lavfi -re -i testsrc=duration=5:size=1920x1080:rate=30000/1001 -s 1920x1080 -pix_fmt yuv420p -f rawvideo out.yuv
x264 --input-res 1920x1080 --intra-refresh out.yuv --b-pyramid none -b 0 --ref 0 -o out.264
Verification:
ffprobe -show_frames out.264 |grep pict_type=I
Or just looking at the x264 output e.g.

Thanks to #Gyan and #nobody555 this works:
ffmpeg -f lavfi -re -i testsrc=duration=60:size=1920x1080:rate=30000/1001 -s 1920x1080 -pix_fmt yuv420p -f rawvideo -|x264 --input-res 1920x1080 --intra-refresh -o - -|ffmpeg -r "30000/1001" -fflags +genpts -i - -c copy -movflags frag_keyframe+empty_moov -f mp4 -|ffmpeg -i - -ss 200ms -c copy -f mpegts out.ts -y
So, I'm using this code to compress my *mp4 file. I need to get lower quality and decrease bitrate:
ffmpeg -i input.mp4 -c:v libx264 output.mp4
The problem is: the last frame of footage is dropped after ffmpeg compression.
Screenshot is here: screenshot_ffmpeg_drop frame
I tried to use full preferences I need, but the problem is the same.
ffmpeg -i input.mp4 -c:v libx264 -vf scale=1280:720 -preset fast -crf 29 -r 25 -c:a copy output.mp4

I am trying to convert a stack of 447 still images (jpg) to video using avconv on ubuntu 14.04
avconv -f image2 -i aligned_%04d.tif.jpg -r 10 movie.mkv

The resulting video runs about 18s, but seems to contain only the first frame. Changing the framerate will still end up with ~18s and only the first frame.
My expectation was: Every image would be used for one frame and the higher the framerate the shorter the video. And of course: The video should contain all images.
Is my expectation wrong? Or what could be the cause for my problem?
My command is mainly based on: https://libav.org/avconv.html#toc-image2-1
I would much rather like to delete the question.
When converting the input frames from tif (which were not accepted by avconv) to jpg, I must have hosed them up. All 447 images were actually a copy of the first one. That explains the video issues, which were no issues really.
