MP3 files created using FFmpeg are not starting playback in browser immediately. Is there any major difference between FFmpeg and AVCONV ?
23 janvier 2019, par AR5I am working on a website that streams music. We recently changed server from Debian (with avconv) to a Centos7 (with FFmpeg) server.
The mp3 files created on Debian server start playback on browser (I have tested Chrome and Firefox) start almost at the same time they start loading into the browser (I used Network tab on Developer Tools to monitor this)Now after the switch to Centos/FFmpeg server, the files being created on this new server are displaying a strange behavior. They only start playback after about 1MB is loaded into the browser.
I have used identical settings for converting original file into MP3 in both AVCONV and FFmpeg but the files created using FFmpeg are showing this issue. Is there something that might be causing such an issue ? Are there differences in terms of audio conversion between AVCONV and FFmpeg ?
I have already tried
I first found that the files created on old server (Debian/Avconv) were VBR (variable bitrate) and the ones created on new server were CBR (constant bitrate), so I tried switching to VBR but the issue still persisted.
I checked the mp3 files using MediaInfo app and there seems to be no difference between the files.
I also checked if both files were being served as 206 Partial Content and they both are indeed.
I am trying to create mp3 files using FFmpeg that work exactly like the ones created before using avconv
I am trying to make the streaming site work on the new server but the mp3 files created using FFmpeg are not playing back correctly as compared to the ones created on the old server. I am trying to figure out what I might be doing wrong ? or if there is a difference between avconv and FFmpeg that is causing this issue.
I am really stuck on this issue, any help will be really appreciated.
Edit
I don’t have access to old server anymore so I couldn’t retrieve the log output of avconv. The command that I was using was as follows :
avconv -y -i "/test/Track 01.mp3" -ac 2 -ar 44100 -acodec libmp3lame -b:a 128k "/test/Track 01 (converted).mp3"Here is the command and log output from new server :
ffmpeg -y -i "/test/Track 01.mp3" -ac 2 -ar 44100 -acodec libmp3lame -b:a 128k "/test/Track 01 (converted).mp3"

ffmpeg avcodec_send_packet/avcodec_receive_frame memory leak
23 janvier 2019, par G HamlinI’m attempting to decode frames, but memory usage grows with every frame (more specifically, with every call to avcodec_send_packet) until finally the code crashes with a bad_alloc. Here’s the basic decode loop :
int rfret = 0;
while((rfret = av_read_frame(inctx.get(), &packet)) >= 0){
if (packet.stream_index == vstrm_idx) {
//std::cout << "Sending Packet" << std::endl;
int ret = avcodec_send_packet(ctx.get(), &packet);
if (ret < 0 || ret == AVERROR(EAGAIN) || ret == AVERROR_EOF) {
std::cout << "avcodec_send_packet: " << ret << std::endl;
break;
}
while (ret >= 0) {
//std::cout << "Receiving Frame" << std::endl;
ret = avcodec_receive_frame(ctx.get(), fr);
if (ret == AVERROR(EAGAIN) || ret == AVERROR_EOF) {
//std::cout << "avcodec_receive_frame: " << ret << std::endl;
av_frame_unref(fr);
// av_frame_free(&fr);
break;
}
std::cout << "frame: " << ctx->frame_number << std::endl;
// eventually do something with the frame here...
av_frame_unref(fr);
// av_frame_free(&fr);
}
}
else {
//std::cout << "Not Video" << std::endl;
}
av_packet_unref(&packet);
}Memory usage/leakage seems to scale with the resolution of the video I’m decoding. For example, for a 3840x2160 resolution video, the memory usage in windows task manager consistently jumps up by about 8mb (1 byte per pixel ??) for each received frame. Do I need to do something besides call av_frame_unref to release the memory ?

}Update 1 : (1/21/2019) Compiling on a different machine and running with different video files I am not seeing the memory usage growing without bound. I’ll try to narrow down where the difference lies (compiler ?, ffmpeg version ?, or video encoding ?)
Update 2 : (1/21/2019) Ok, it looks like there is some interaction occurring between ffmpeg and Qt’s QCamera. In my application, I’m using Qt to manage the webcam, but decided to use ffmpeg libraries to handle decoding/encoding since Qt doesn’t have as comprehensive support for different codecs. If I have the camera turned on (through Qt), ffmpeg decoding memory consumption grows without bound. If the camera is off, ffmpeg behaves fine. I’ve tried this both with a physical camera (Logitech C920) and with a virtual camera using OBS-Virtualcam, with the same result. So far I’m baffled as to how the two systems are interacting...

Concatenating multiple mp4 files [duplicate]
18 octobre 2019, par Mr MedusaThis question already has an answer here :
I’m currently trying to join multiple mp4 video files into one file, and I found the ffmpeg library and looked at a lot of ways on how I should use it.
Currently I’m usingffmpeg -f concat -safe 0 -i mylist.txt -c copy output.mp4This should work, but for some reason it doesn’t. My terminal is filled with this
(Can’t give anymore output than this)

At least one output file must be specifiedI’ve read most of the posts on here about ffmpeg causing this issue for other people, but none of the fixes that are explained have worked for me.
The video output I get seems fine for the first video, but then once it’s supposed to transition into the other videos it just "freezes" or sets the speed to something like 100x. Output video also ends up being 28 minutes long instead of 2.8 minutes.
Anyone able to help me ?
