Retranslating video stream using ffmpeg
6 mai 2014, par zdimon77I want to redirect video stream from rtmp to hls format using nginx rtmp-module.
This my nginx config
server { exec_options on; listen 1936; chunk_size 4000; application myapp { live on; exec /usr/bin/avconv -loglevel verbose -re -i rtmp://localhost:1936/myapp/$name -vcodec libx264 -vprofile baseline -acodec libmp3lame -ar 44100 -ac 1 -f flv rtmp://localhost:1935/hls/$name; } } server { listen 1935; chunk_size 4000; application hls { live on; hls on; hls_path /tmp/hls; } }But it doesnt work. When I try to publish my stream in console (without exec command in nginx.conf)
ffmpeg -loglevel debug -re -i rtmp://localhost:1936/myapp/test -vcodec libx264 -vprofile baseline -acodec libmp3lame -ar 44100 -ac 1 -f flv rtmp://localhost:1935/hls/testI see this in console

How to control insert position when insert video frames to pure audio file with ffmpeg
6 mai 2014, par teddyInserting video frames into pure audio flv file(may call it audio.flv) can make it seekable.I do this with ffmpeg using the following command:
/usr/bin/ffmpeg -y -loop 1 -i /root/testimage.jpg -i /file/audio.flv -s 2x2 -t 90 -r 1 -g 0 -acodec copy /tmp/out.flv 2>&1The number 90 in command is specify the file duration.this can work well except one thing: The output files for several executions of the previous command is not same. After i analysed the file's with flvparser i found that the position of the first video tag of these files were not same.
- For the first situation, the first video tag is the third tag, which is following script tag
- For the second situation, the first video tag is the fifth tag, there are three audio tags between it and script tag.
- For the third situation, the first video tag is the sixth tag.
I just got these three situations for my test. But other video tags are in the same position of tag-index in output file. I have no idea why is just the first video tag has different position. I want all video tag will be at same tag-indexes. Could anyone give me some advise? Thanks!

ffmpeg and streaming video - frame time issue
6 mai 2014, par 4ntoineI've compiled ffmpeg-android (https://github.com/appunite/AndroidFFmpeg) and it works for files. The problem is that it shows nothing for network streams (both rtmp and hls) as frame timestamp is too big and it seems to be not from video beginning (as for file). Then it waits for the first frame time which for network stream is too big:
player_decode_video copying... 05-05 18:11:26.994: INFO/player.c(16998): player_decode_video Decoded video frame: 568.233000, time_base: 51140970 05-05 18:11:26.994: INFO/player.c(16998): player_wait_for_frame[0] start ... 05-05 18:11:30.587: INFO/player.c(16998): player_wait_for_frame[0 = Video] = (568.233000) - (0.000977) 05-05 18:11:30.587: INFO/player.c(16998): player_wait_for_frame[0] Waiting for frame: sleeping: 568232023 05-05 18:11:31.088: INFO/player.c(16998): player_wait_for_frame[0] timeout 05-05 18:11:31.088: INFO/player.c(16998): player_wait_for_frame[0 = Video] = (568.233000) - (0.501542) 05-05 18:11:31.088: INFO/player.c(16998): player_wait_for_frame[0] Waiting for frame: sleeping: 567731458 05-05 18:11:31.588: INFO/player.c(16998): player_wait_for_frame[0] timeout 05-05 18:11:31.588: INFO/player.c(16998): player_wait_for_frame[0 = Video] = (568.233000) - (1.002778) 05-05 18:11:31.588: INFO/player.c(16998): player_wait_for_frame[0] Waiting for frame: sleeping: 567230222 05-05 18:11:32.089: INFO/player.c(16998): player_wait_for_frame[0] timeout 05-05 18:11:32.089: INFO/player.c(16998): player_wait_for_frame[0 = Video] = (568.233000) - (1.504563) 05-05 18:11:32.089: INFO/player.c(16998): player_wait_for_frame[0] Waiting for frame: sleeping: 566728437 05-05 18:11:32.590: INFO/player.c(16998): player_wait_for_frame[0] timeout 05-05 18:11:32.590: INFO/player.c(16998): player_wait_for_frame[0 = Video] = (568.233000) - (2.005708) 05-05 18:11:32.590: INFO/player.c(16998): player_wait_for_frame[0] Waiting for frame: sleeping: 566227292also i can't figure out what timestamp for frame for network stream means (for file frames it's a time from video beginning)
for file it's clear: time_base is frame number and timestamp is time from video beginning and it plays the files:

its can be opened now but it wait for frame time which is far in the future)?
UPDATE:
int64_t pts = av_frame_get_best_effort_timestamp(frame); if (pts == AV_NOPTS_VALUE) { pts = 0; } int64_t time = av_rescale_q(pts, stream->time_base, AV_TIME_BASE_Q); LOGI(10, "player_decode_video Decoded video frame: %f, time_base: %" SCNd64, time/1000000.0, pts); player_wait_for_frame(player, time, stream_no);it extracts time which is far in future:
player_wait_for_frame[0 = Video] = (568.233000) - (0.000977)Is it correct?
