the pjsua runs in openwrt, we use USB SoundCard.
When we answer a call, allways choopy, both the capture and the playback are not work well!
Tips:We have use auddemo tested my soundcard, recoreding/playing are good, and the capture id is 8, playback id is 1.
thank you~~

Beforte I compling simple_pjsua.c I set the log level frome 4 to 5.After complied and I run it, I fond the same warnging as you, but have no effect to the session.when I set the log level from 5 back to 4,the waring disappeared.I didn't know the reasion that cause the waring but I know it dosn't have effect to the session.

I encode a new H.264 video muxed with audio in MP4 file.
How to correctly calculate PTS and DTS for AVPacket and AVFrame for video and audio?
I generate new video frames and new audio from my source. There are no original PTS/DTS information. I know frame rate which I need to use (time_base).
Assuming your frame rate is constant. And after setting stream time bases correctly. Start both pts's from zero (0). Audio pts will increase by 'sample per frame' for each frame. This is typically audio_sample_rate / frame_rate (i.e. 48000/60 = 800).
For the video, things are different and somewhat simpler. Video pts will increase same amount of 'Video frame duration' per frame. Use this cheat sheet to calculate the duration:
FPS Frame duration
23.98 2002
24.00 2000
25.00 2000
29.97 2002
30.00 2000
50.00 1000
59.94 1001
60.00 1000
Yes these somewhat hacky but will work.
I have a file .m4a audio file of size 805 kb which I wanted to convert it to wav. My purpose is to (1) get highest quality .wav audio file and (2) get 320 kbps .mp3 audio file.
I used an online service (https://www.online-convert.com) to convert it. When I converted directly without optional settings, the file size increased to 11.6 mb and when I converted the same audio with optional settings like, changing bit resolution to 32 Bit and changing sampling rate to 96000 Hz, the file size jumped to 50.7 mb
There are only two optional settings in the web service
Bit resolution - no change, 8 bit, 16 bit, 24 bit, 32 bit
Sampling rate - no change, 1000 hz, 8000, 11025, 16000, 22050, 24000, 32000, 44100, 48000, 96000 hz
And one raido button for Normalize audio that can be checked and unchecked
Can someone explain why the file size increases and what settings I must keep to get the highest quality from the original 805 kb audio?
Thanks
I have a task to add running text to video stream (or file) on receive. Video need to be run on cubieboard with Armbian. I tested with mpv, with flag --hwdec=vdpau, and the video runs smoother that without it. To add running text I tried to use lavfi-drawtext filter, but when I use it, mpv falls back to software decoding and lag is seen. Here is one of the examples I used:
mpv --hwdec=vdpau Videos/VID* -vf lavfi=[drawtext=fontsize=40:fontcolor=yellow:x=w-50*t:y=h/2:textfile=livetext.txt:reload=1]
And an output from that command with --msg-level=vd=v, it is from my working PC, on cubieboard it also warns about audio/video desync:

After a long search I doubt that hardware acceleration with mpv here is possible. If so, maybe you could give advice on other tools to achieve that? I am a newbie in this sphere and maybe there is a more efficient way to add running text to video. Thanks.
I found a format of subtitles that can move text (ASS), so that no video filters are needed. Tag \move(x1,y1,x2,y2) can do that, reference to tags below:
http://docs.aegisub.org/3.2/ASS_Tags/
I am trying to measure voice-quality (PESQ Score) by playing a file at server and recoding it at client-side and then passing both files to ITU implementation of PESQ score computation.
While the codec negotiated is PCMU(G.711) so I should get PESQ score of 4.1 (or something near that) but the score I am getting is in range of 3.4-3.7.
After computing score for more than 40 recordings PESQ Scores I am getting is:
AVG: 3.4278035714
MAX: 3.707
MIN: 3.343
I don't understand what is it that I am doing incorrectly. Why am I not getting scores close to 4.1 ??
Setup:
File (PCM#8000) --- FreeSwitch(PCMU#8000) ---PJSIPClient(PCMU#8000)---File(PCM#8000)

I want to reduce the muxing overhead when creating .ts files using FFMPEG.
Im using FFMPEG to create a series of transport stream files used for HTTP live streaming.
./ffmpeg -i myInputFile.ismv \
-vcodec copy \
-acodec copy \
-bsf h264_mp4toannexb \
-map 0 \
-f segment \
-segment_time 10\
-segment_list_size 999999 \
-segment_list output/myVarientPlaylist.m3u8 \
-segment_format mpegts \
output/myAudioVideoFile-%04d.ts
My input is in ismv format and contains a video and audio stream:
Stream #0:0(und): Video: h264 (High) (avc1 / 0x31637661), yuv420p, 320x240, 348 kb/s, 29.97 tbr, 10000k tbn, 59.94 tbc
Stream #0:1(und): Audio: aac (mp4a / 0x6134706D), 44100 Hz, stereo, fltp, 63 kb/s
There is an issues related to muxing that is causing a large amout of overhead to be added to the streams. This is how the issue was described to me for the audio:
So for a given aac stream, the overhead will be 88% (since 200 bytes will map to 2 x 188 byte packets).
For video, the iframe packets are quite large, so they translate nicely into .ts packets, however, the diffs can be as small as an audio packet, therefore they suffer from the same issue.
The solution is to combine several aac packets into one larger stream before packaging them into .ts. Is this possible out of the box with FFMPEG?
It is not possible. Codecs rely on the encapsulating container for framing, which means to signal the start and length of a frame.
Your graphic actually misses an element, which is the PES packet. Your audio frame will be put into a PES packet first (which indicates its length), then the PES packet will be cut into smaller chunks which will be TS packets.
By design you can not start a new PES packet (containing an audio frame in your case) in a TS packet which already contains data. A new PES packet will always start in a new TS packet. Otherwise it would be impossible to start playing mid-stream (broadcast sitation) - it would be impossible to know on which byte in the TS the new PES begins (remember you have missed the beginning of the current PES).
There are some mitigating factors, the FF FF FF padding will probably be compressed by the networking hardware. Also if you are using HTTP (instead of UDP or RDP), gzip compression can be enabled (but I doubt it would help much).
I've fixed the worst problem of syncing the TS output on each frame in http://git.videolan.org/gitweb.cgi/ffmpeg.git/?a=commit;h=75c8d7c2b4972f6ba2cef605949f57322f7c0361 - please try a version after that.
