Could not encode video packet with h264 #1563
Description
I record rtmp to a video file with x264 encorder with errors, similler to #778. I have add recorder.setVideoOption("threads", "1");, but still the same error. when i remove line recorder.setVideoCodec(avcodec.AV_CODEC_ID_H264);, it work fine. but the video file is not H264 ecoder. I use javacv-platform 1.5.4. and i did not use multithreading. below is my code and exception.
Snippet from code:
FFmpegFrameGrabber grabber = new FFmpegFrameGrabber("rtmp://10.160.21.186/live/camera_11");
grabber.start();
String videoFile = videoSavePath + File.separator + DateFormatUtils.format(t1, "yyyyMMddHHmmss") + ".mp4";
FFmpegFrameRecorder recorder = new FFmpegFrameRecorder(videoFile, 1280, 720, audioChannel);
recorder.setVideoOption("threads", "1");
recorder.setFrameRate(grabber.getFrameRate());
recorder.setVideoCodec(avcodec.AV_CODEC_ID_H264);
recorder.setFormat("flv");
recorder.start();
Frame frame;
int frames = 0;
int conNullFrames = 0;
while (conNullFrames <= 5) {
if((frame = grabber.grabFrame()) != null){
conNullFrames = 0;
recorder.record(frame);
frames ++;
if (frames >= grabber.getFrameRate() * 30) {
recorder.stop();
and i got this error:
org.bytedeco.javacv.FrameRecorder$Exception: avcodec_encode_video2() error -542398533: Could not encode video packet.
